Description of the invention (1) [Background of the invention] [Field of the invention] The present invention relates to a sewage treatment device and an agglutination and sedimentation device, and more particularly, to a sewage treatment device and a phosphorus treatment component that precipitates water-insoluble metal salts and precipitates in the treated water and Aggregation sedimentation device. [Previous technical description] Conventionally, an sewage treatment device is equipped with an electrode. As the electrode undergoes electrical decomposition to generate metal ions, the phosphorus component in the treated water forms water-insoluble metal salts and precipitates. In such a sewage treatment apparatus, electrodes are provided in an electrolytic cell. Conventionally, the electrolytic cell in a sewage treatment system has a mode as shown in FIG. Referring to Fig. 38, the electrolytic cell 800 is provided with electrodes 801 and 802 provided therein, and is provided with an introduction port 803 for introducing treated water. The electrodes 801 and 802 are connected to separate power sources, and when either one is energized, it is electrically decomposed. The metal ions generated by such electrical decomposition are introduced into the treated water through the introduction port 803, and react with the phosphorus component therein to form water-insoluble metal salts. The bottom of the electrolytic cell 800 is provided with a shutter 805. The proper operation of the shutter 805 allows the above-mentioned metal salts to be discharged out of the electrolytic cell. However, the conventional sewage treatment device has a problem called metal salts cannot be completely discharged from the electrolytic cell 800, and thus the metal salts prevent the above-mentioned electrical decomposition. Furthermore, the electrolytic tank 800 of the conventional sewage treatment device will be provided with 1229657 V. Description of the invention (2) Other tanks for introducing domestic sewage. Then, the metal salts' discharged to the outside of the electrolytic tank 800 will settle together with the sludge settled in other tanks. Although metal salts will settle with the sludge, it will be difficult to recycle phosphorus from the metal salts. For this reason, high levels of phosphorus need to be recycled, which is considered a problem. Furthermore, in conventional sewage treatment equipment, in order to agglomerate and settle water-insoluble metal salts such as phosphorus components in the treated water, an agglutination tank and an agglutination and sedimentation device are provided. The figure shown in Figure 39 is a block diagram for explaining the flow of a sewage treatment device including a conventional agglutination and sedimentation device. Referring to Fig. 39, the sewage system circulates in the order of the intermediate flow adjustment tank 901, the agglutination tank 902, the agglutination and sedimentation tank 903, and the disinfection tank 904. Thus, the sewage of each treatment tank is discharged from the disinfection tank 904. In order to agglomerate the fixed components in the sewage, a medicament for supplying iron ions or aluminum ions is put into the agglutination tank 902 as a coagulant. Because such a pharmaceutical is put into the sewage, the phosphorus content in the sewage is removed due to agglomeration; in addition, the BOD (biological oxygen demand), SS (suspended matter), and COD (chemical oxygen demand) of the sewage will be low. . The so-called BOD refers to the amount of organic matter which is replaced by the amount of oxygen 値 and may be decomposed by microorganisms. The so-called SS refers to the amount of particles that are insoluble in water but in a free state. The so-called COD is the amount of organic matter that the oxidant may oxidize. It is used to indicate the degree of pollution of water such as seawater. After mixing with the coagulant in the coagulation tank 902, the sewage and the rubber plume generated in the coagulation tank 902 are introduced into the coagulation and sedimentation tank 903 together. -4- 1229657 V. Description of the invention (3) The rubber plume introduced from the agglutination tank 902 is settled in the agglutination sedimentation tank 903; and the clear liquid above the agglutination sedimentation tank 903 is introduced into the disinfection tank 904, and after proper disinfection Be released. However, in the agglutination and sedimentation device shown in FIG. 39, since the agent used for agglutination is an acidic solution, it is dangerous in agglutination operation; therefore, it is necessary to adjust the agglutination tank 9 in order to be able to agglutinate. The pH of 02 makes it difficult to reliably remove the phosphorus component. Moreover, in general, the phosphorous compounds aggregated in the sewage treatment device or the agglutination and sedimentation device are generally in the form of fine particles. For this reason, it is difficult to reliably remove the aggregated phosphorus compound from the treated water. [Summary of the invention] Therefore, the present invention has been researched in view of these related facts. An object of the present invention is to provide a sewage treatment apparatus and an aggregation and sedimentation apparatus capable of reliably removing phosphorus compounds from treated water. Furthermore, another object of the present invention is to recover more phosphorus compounds that exhibit a recyclable state. In addition, the present invention has other objects to provide a sewage treatment device and an aggregation sedimentation device capable of safely aggregating predetermined components such as phosphorus in sewage. According to the situation of the present invention, the sewage treatment device is a kind of sewage treatment device for treating sewage including a sewage treatment area capable of accommodating sewage, and is characterized in that the sewage treatment area of the sewage treatment device is equipped with a magnetic material. Adsorption equipment. According to the present invention, the agglomerates of phosphorus compounds generated in the sewage treatment area are 1229657 V. Description of the invention (4) is capable of being adsorbed by a magnetic adsorption material. Thus, the phosphorus compound is surely removed from the sewage. Furthermore, according to the present invention, a sewage treatment device equipped with a sewage treatment area, an activated sludge tank containing activated sludge, and a filter for treating treated water in the activated sludge tank; the adsorption device is preferably located near the filter. . For this reason, it is possible to avoid the cause of clogging the filter due to the adsorption material adsorbing the aggregate of the phosphorus compound. Moreover, according to the sewage treatment device of the present invention, it is preferable that the adsorption device and the filter are integrated into one. For this reason, the agglomerates of the phosphorus compounds near the filter can be surely adsorbed by the adsorbent. Therefore, the situation where the filter is blocked due to agglomerates of the phosphorus compound is more reliably avoided. In addition, according to the sewage treatment device of the present invention, the sewage treatment area further includes an ion supply area that provides iron ions or aluminum ions, and the sewage treatment area is equipped with: The sedimentation tank where the precipitate formed by the water reaction precipitates; the adsorption equipment is preferably arranged in the precipitation tank. For this reason, phosphorus compounds can be adsorbed very efficiently as adsorbent materials. The phosphorus compound in the treated water reacts with iron ions or aluminum ions, and thus becomes a state adsorbed by the adsorbent. In addition, the sewage treatment apparatus according to the present invention is provided with an ion supply area, an electrode immersed in the treated water, an electrode supporting portion supporting the electrode immersed in the treated water, and a connector of a power source for connecting the electrodes. Connector, 1229657 V. Description of the invention (5) It is more suitable to provide an electrode support section. Therefore, the electrical connection between the 'electrode and the power source is immersed in the treated water and corroded, which can be avoided. Furthermore, according to the sewage treatment device of the present invention, at least a part of the electrode supporting portion is preferably fitted at the place where the cutout portion is formed. Then, the electrode is settled in a fixed position. Therefore, when the distribution of ions supplied from the electrodes of the ion supply area is stable, the sewage treatment capacity of the sewage treatment device is also stabilized. On the other hand, according to other aspects of the present invention, the sewage treatment device of the present invention includes an electrolytic unit equipped with an electrode, and the phosphorus component of the treated water becomes water-insoluble due to the electrical decomposition of the electrode in the electrolytic unit. The metal salt is precipitated, which is characterized in that: in the electrolytic unit of the sewage treatment device, a box cover covering the side portion of the electrode is provided. According to the present invention, since the electrode system is covered by the box cover, the electrode is efficiently reacted with the treated water by the metal ions generated by the electrolysis. Therefore, because there is no electrode at the bottom of the case, metal salts generated by the reaction of metal ions with the phosphorus component in the treated water will quickly move to the place away from the electrode. Therefore, in terms of the metal salts precipitated in the sewage treatment device, it is possible to avoid the electrical decomposition of the electrodes and the low reaction efficiency of the metal ions with the phosphorus components in the treated water. Furthermore, the phosphorus compounds in the sewage treatment plant can be reliably removed. In addition, according to the sewage treatment device of the present invention, for the purpose of agitating in the space surrounded by the box cover 1229657 V. Description of the Invention (6), the electrolytic unit is more preferably provided with agitating equipment. For this reason, the metal ions produced by the electrical decomposition of the electrode can react with the treated water more efficiently. In addition, the sewage treatment device «a according to the present invention includes: an anaerobic tank in which anaerobic microorganisms are present, an aerobic tank in which aerobic microorganisms are present, and a sedimentation tank for sedimentation of sludge; the electrolytic unit is preferably It is set in the anaerobic tank or the anaerobic tank. Therefore, the sewage treatment device can be relatively compact. 0 According to another aspect of the present invention, the sewage treatment device of the present invention includes an electrolysis unit equipped with electrodes. The electrolysis of the electrodes in the electrolysis unit and the formation of phosphorus components in the treated water The water-soluble metal salts are precipitated and are characterized in that the waste water treatment device for selectively recovering the huge amount of metal salts further includes a recovery unit disposed downstream of the electrolytic unit and adjacent to the electrolytic unit. According to the present invention, The metal salts y precipitated in the sewage treatment device are recovered by the recovery unit. Therefore, it is necessary to control the mixing of metal salts and sludge in the sewage treatment device. Therefore, it is possible to avoid the hindrance of the reaction of the precipitated metal salt j near the electrode, and to make the recovery of the above-mentioned metal salt in a renewable state higher.

-► Η令 *··(2) -17- 1229657 五、發明說明（16) 再者，+極所生成之2價鐵，由於空氣氧化而變成3價 鐵。一旦，電極41及42乃由鋁所構成之場合，一極之反 應不改變，但+極之電解反應則表示成如下式（3 ): + 極：A1 -► Al3+ + 3e' ---(3) 以下茲以由鐵所構成的電極41及42之場合，來說明本 具體實施例。除了特定埸合外，在所有的觀點中，鐵係可 能變更爲鋁。 在式（1)電解反應之氧化反應中所生成之3價鐵離子 (Pe3+ )，係利用來作爲凝集由第一迴流管24所返送處理水 中之磷化合物之用。此外，使用Fe3+所凝集之磷化合物， 其主要之反應式係如式（4 )所示： P〇43 - +Fe3+ -► FePO| · · . (3) 形成於電解槽37底部之閥43，係爲了從電解槽37中除 去在電解槽37內的凝集物或污泥。當閥43打開時，在電 解槽37內的凝集物或污泥，則向第一厭氣濾床槽5移動。 第2圖所示係爲電解槽37及其附近之詳細構造圖。參照 第2圖，從第一迴流管24所返送之處理水，係從電解槽 37之流入口而流進電解槽37。在電極41及42附近處係配 備有第三散氣管40。在電極41及42附近之空氣，則係由 第三散氣管4 0來供給。 覆於排出口 47之蓋36係連接到浮球35上。此外，蓋 36係以絞鏈34而連接於排出口 47之下端處，而使得排出 口 47可以重複地開合。因此，第一厭氣濾床槽5之水位， -18- 1229657 五、發明說明（彳7) 在蓋36爲打開狀態之埸合下，當水位爲100A時，第一厭 氣濾床槽5內之溶液並不通過排出口 47而流入電解槽37 中；當水位爲100B時，第一厭氣濾床槽5內之溶液則通過 排出口 4 7而流 入電解槽3 7中。 在第一厭氣濾床槽5之水位爲100A之場合下，浮球35 係在第2圖中以符號35A所示之位置上；而蓋36則以符號 3 6A表示之；此時排出口 47係爲打開狀態。另一方面，第 一厭氣濾床槽5之水位係在100B之場合下，浮球35係在 第2圖中以符號35B所示之位置上；此時排出口 47係爲關 閉狀態。所以，在本具體實施例中，排出口 47係爲蓋36 所覆蓋，而且接續於浮球之蓋36得以確實避免了從流入口 6所流入之生活污水混入浮渣，並避免其直接流入電解槽 37中。再者，上述之水位100A係爲第一厭氣濾床槽5內 之溶液流入電解槽37之水位，也含有該溶液中之浮渣等並 不流入電解槽37中這樣的水位之意。 在電解槽37中係設有如圖示之控制件。該控制件係控制 閥43之開閉、電極41及42所流通之電流値、電極41及 42間之電壓値、第三散氣管40所吹出之空氣量、在電極 4 1及42中所印加電壓之極性等。 水位感測計48係爲了監測第一厭氣濾床槽5之水位，使 達到預定的水位之目的而設計的。水位感測計48所檢測出 之出力即爲上述控制件之入力。在此，預定的水位，係爲（ -19*· 1229657 五、發明說明（18) 例如）從流入口 6所流入之生活污水，直接流電解槽3 7中 之水位。因此，當水位達到預定之水位而爲感測計48所檢 測出之場合下，則控制件會發出以聲音等所表示之警告。 在此等控制件之構成中，由於通過排出口 6之排水流入量 受到了調整，因而通過排出口 6流入之生活污水並不會直 接流入電解槽37中，所以可確實地避免浮渣流入電解槽 37中。另外，上述預定之水位係爲第一厭氣濾床槽5內之 溶液流入電解槽37之水位，也是該溶液中之浮渣不流入電 解槽3 7中之水位。 進行本具體實施例污水處理系統之維修人員，係視是否 產生上述之警告，來判斷是否使從出口 6流入之生活污水 直接流入電解槽37中。於是，在不配備有蓋3 5及浮球36 之場合時，依警告之有無來判斷電極41及42附近是否堆 積了浮渣，則可容易地來判斷淸掃電極4 1及42之必要性 〇 此外，在水位感測計48檢測出達到預定水位之場合時， 則控制件會進行控制第三散氣管40空氣之供給量增加。進 行此種控制之控制件，即使在浮渣流入電極41及42附近 之場合下，當從第三散氣管所供給之空氣量增加時，該浮 渣會排出到電解槽37之外。因此，得以確實避免了浮渣在 電極41及42之附近堆積。 總之，以上所說明的具體實施例係至少配備有含浮球35 和蓋36之組合件，或者是水位感測計48中之任選一種， -20- 1229657 五、發明說明（19) 因而，避免了浮渣堆積在電極41及42之附近。 電極41及42係安裝於各個電極支撐部41A及42A上。 電極41及42頂部位置上之電極支撐部41A及42A並不浸 在電解槽37之處理水中，此電極支撐部41A及42A係由以 下所述之支撐棒3 7A及3 7B所支撐著。在第3圖中所示者 係爲電極41及42、以及電極支撐部41A及42A之構造圖 。另外，在第4圖所示者係爲安裝在電解槽37上方之電極 41及42、以及電極支撐部41A及42A之組合圖。 參照第3及第4圖，電極41及42係以螺栓固定在各個 電極支撐部41 A及42A之頂部上。電極支撐部41A與電極 支撐部42A之相對的適當面上，係按裝有墊片405。然後 ，在第4圖中所示之電極支撐部41A及42A，透過墊片405 而相向地組合並固定。適當地調整墊片405，所以可適當 地調整電極41及42之距離。 在此說明，電極支撐部41A及42A之構成。第5圖係爲 電極支撐部4 1 A之敘視圖。電極支撐部4 1 A係內包有電源 裝置38和電極41所接續之配線。該配線之一端係爲連接 器410，而另一端爲連接器411。由於電極41係以螺栓固 定在電極支撐部41A上，所以電係接到連接器410上。另 外，連接器411係電氣連接到電源裝置38上。因此，以螺 栓固定在電極支撐部41A上之電極41係電氣連接到電源裝 置38上。此外，電極支撐部42A係與電極支撐部41A —樣 有2個連接器並且內包配線。於是，以螺栓固定在電極支 -21 · 1229657 五、發明說明（2〇) 撐部41A上之電極41與電源裝置38則相互電氣連接。 爲了使電極41和42以及電極支撐部41A和42A具有如 此之構成，則電極41及42和電源裝置38之結配線，應避 免從本具體實施例之污水處理系統之處理水中橫越。此外 ，具有此種接續件之連接器，應避免浸在處理水中而受到 腐蝕。 第6圖係爲電解槽37之敘視圖。在電解槽37上方之2 支支撐棒37A及37B係依預定間隔來設置。電極支撐部 41 A和42A之下方，係配置在電解槽37上所設置的支撐棒 37A及37B之上。總之，電極41及42係在各個支撐棒37A 及37B之間。 爲了不在電解槽37中產生電極41及42之位置，因而備 有1個用以支撐更且備有切凹部之電極支撐部。在第7圖 中所示者，係爲支撐電極41及42並備有切凹部之電極支 撐部。 在電極支撐部450之表裏面上，係形成了嵌入到各個電 極41及42上方之切凹部451。在各個切凹部451上之電 極41及42，係於電極41及42之上方嵌入並以螺栓固定 之。因而，電極41及42在電解槽37內之位置，得以更確 實地固定，而電解槽37內之鐵離子分布亦穩定了。從而， 式（4)之反應，在電解槽37中安定地起反應。因而，本具 體實施例之污水處理裝置，具有安定的污水處理能力。而 且，當電極支撐部450係設置於電解槽37上方時，右端 •22- 1229657 五、發明說明（21) 450A及左端450B之下方，其係與支撐棒37A及37B接觸 。於是，電極41及42成爲設置在電解槽37而爲支撐棒 37A及37B所挾隔之狀態。 電極支撐部45 0與電極41及42係爲單元化輸送之場合 ，如第8圖所示，較佳爲收納於盒套中輸送。詳細言之， 單元化之電極支撐部450及電極41及42，係指電極41及 42之一部份乃是收集於盒套460內，並以盒套460收納之 。於是，在收納時，電極支撐部45 0之右端450A和電極支 撐部450之左端450B，係分別以螺栓461及462而固定於 盒套中。 【具體實施例2】 其次，說明本發明之具體.實施例2。因此，具體實施例2 到6之各個污水處理裝置，係以去除污水中磷化合物爲主 要目的而設置的污水處理裝置，各個污水處理裝置可以單 體來使用，也可與具厭氣濾床槽等之收容厭氣性微生物之 處理槽等組合使用。 參照第9圖，活性污泥槽6 1乃收容活性污泥用，其係由 從其他裝置來之污水係透過流入口 69而送入此處所構成。 在活性污泥槽6 1之底部，係配設有第一散氣管62。第一 散氣管62，係接續於第一鼓風機65，經由第一鼓風機所供 給的空氣，係由空氣吹出口而釋放出來。於是，活性污泥 槽61內部得以維持喜氣狀態，處理水則由於喜氣性微生物 而行喜氣分解，氨氮則由於硝化作用而分解成硝酸氮。 -23- 1229657 五、發明說明（22) 循環管63之一端係插入於活性污泥槽61中。活性污泥 槽61中之處理水，係由於泵64而透過循環管63而送入電 解槽37中。此外，活性污泥槽61中處理水之上澄液，通 過輸送管77而送入沉澱槽67中。 離子供給槽70係備有電極71及72時，這些電極係可以 由鐵或鋁所構成。電極71及72係通過配線73A而接續於 電裝置上，由於電解而提供了離子供給槽70中之鐵或鋁離 子。然後，由於供給了此類金屬離子，離子供給槽70中之 磷化合物，依從如以上所述之式（4 )而凝集。離子供給槽 70中電極71及72之下方，係配設有第二散氣管74。第二 散氣管74係接續於第二鼓風機66，經由第二鼓風機所供 給的空氣，係由空氣吹出口而從電極71及72附近釋放出 來。第二散氣管74之下方係設有閥75。閥75係設計成可 以打開或關閉，通常係爲關閉狀態；如此，適當地開放閥 75而使得離子供給槽70之污泥或凝集物排出到到活性污 泥槽61中。 並且，活性污泥槽61中係備有磁石6 1A。然後，離子供 給槽70中所生成磷化合物之凝集物，乃爲磁石6 1 A所吸附 。因此，本具體實施例之污水處理裝置，得以將處理水中 之磷化合物確實地去除。酸化所形成之磷化合物之凝集物 ，係爲磁石6 1 A所吸附。然後，本具體實施例之磁石6 1 A ，乃以吸附方法爲目的之磁性組件所構成。 電極71及72係與則述電極41及42 —樣，各個電極71 -24- 1229657 五、發明說明（23) 及72之上端係具有與電極41及42同樣的形狀之電極支撐 部71 A及72A所支撐著。 電極支撐部71A及7 2A亦與電極支撐部41A及41B相同 ，者具有2個連接器，並內包有各種的炭線。 再者，電極支撐部71A及72A亦與電極支撐部450同樣 ，電極7 1及7 2係嵌入形成切凹部之處。 另外，本具體實施例之離子供給槽70中，從活性污泥槽 6 1來之活性污泥係與處理水中一起送入。於是，依從前述 式（4)之反應生成物乃成爲凝集物而沉降，即使離子供給槽 70係在長期處理期間之場合下，電極7 1及72之電解反應 也比較快速地起反應。此外，電極71及72間之距離，當 考慮大量的污泥時，係以2公分以上較佳。 一方面係處理水之上澄液送入沉澱槽67中，並透過排出 口 78而排；而另一方面，污泥68則係堆積於沉澱槽之底 部。沉澱槽中之污泥68則定期將之除去。 由於本具體實施例之污水處理裝置係備有磁石6 1 A，則 此裝置之規模係達成了約90〜95%以上高磷化合物之去除率。 【具體實施例3】 其次，說明本發明之具體實施例3。 參照第10圖，活性污泥槽81乃收容活性污泥用，其係 由從其他裝置來之污水係透過流入口 89而送入此處所構成 。在活性污泥槽81之底部，係配設有第一散氣管82。第 一散氣管82，係接續於第一鼓風機85，經由第一鼓風機所 -25- 1229657 五、發明說明（24) 供給的空氣，係由空氣吹出口而釋放出來。 循環管8 3之一端係插入於活性污泥槽81中。活性污泥 槽81中之處理水，係由於泵84而透過循環管83而送入電 解槽90中。此外，活性污泥槽81中，在前端處係配設有 配備備膜97之輸送管98 ’膜97係一部份受於活性污泥槽 81之內。於是，活性污泥槽81內之處理水，係通過膜97 由泵8 7經輸送管9 8內部而自活性污泥槽8 1中排出。所使 用之膜9 7，係可以使用其膜之孔徑係約〇 . 〇 5〜1微米之平 膜或中空綠膜。 電解槽90係備有電極91及92時，這些電極係可以由鐵 或鋁所構成。電極91及92係接續於電裝置93上時，由於 電解而提供了電解槽90中之鐵或鋁離子。電解槽90中電 極91及92之下方，係配設有第二散氣管94。第二散氣管 94係接續於第二鼓風機86，經由第二鼓風機86所供給的 空氣，係由空氣吹出口而從電極9 1及92附近釋放出來。 第二散氣管94之下方係設有閥95。閥95係設計成可以打 開或關閉，通常係爲關閉狀態；如此，適當地開放閥95而 使得離子供給槽70之污泥或凝集物排出到活性污泥槽81 中〇 電極91及92係與前述電極41及42 —樣，各個電極91 及92之上端係具有與電極41及42同樣形狀之電極支撐部 (圖示略）所支撐著。 再者，膜97係安裝有磁石97A。於此，詳細說明膜97 -26- 1229657 五、發明說明（25) 與磁石97A之構造。第11圖爲膜97與磁石97A之之側面 圖。 參照第10圖及第11圖，磁石97A係具有加速管之形狀 。因此，磁石97A中央之孔，係安裝有膜97而覆蓋於其表 裡兩面上。第12圖係爲磁石97A之部份斜視圖。磁石97A 之上端部分係形成開□，該開口係接續於輸送管98之一端 上。也就是說，本具體實施例之污水處理裝置，磁石97A 附近之處理水，係經膜97而導入輸送管內。 本具體實施例之磁石97 A係設於膜97之附近，因爲磷化 合物之凝集物乃爲磁石97A所吸著，所以抑制了到達膜97 這樣的事，如此則膜9 7之孔隙堵塞亦受到了抑制。 本具體實施例.中實施例2之沉澱槽67，則考慮了變更膜 97。於是，污水處理裝置變得更緊密。 此外，本具體實施例係備有磁石97，而且經膜所過濾之 處理水，可達成90%以上之高磷化合物之去除率。 以上所說明之本具體實施例中之磁石97A，係由以吸附 手段爲目的之磁性組件所構成。於是，膜9 7乃構成過濾 活性污泥槽內處理水爲目的之過濾器。又，本具體實施例 中磁石97A與膜97，係設計成一體的，本發明並不僅限定 於此種構成。雖然設計成一體較佳，但是並不一定要設計 成相互靠近之一體設計。 【具體實施例4】 其次，說明本發明之具體實施例4。 -27- 1229657 五、發明說明（26) 參照第13圖，活性污泥槽1〇1係以隔牆板1〇7而分割成 收容活性污泥之部分，以及不收容活性污泥之部分。此外 ’隔牆板107之下方，係具有接續於活性污泥槽1〇1之可 供處理水及污泥移動的間隙。又，活性污泥槽1 〇 1係爲通 過流入口 1 09等之裝置而送達污水之構成。活性污泥槽 101之底部係配設有第一散氣管102。第一散氣管102係接 續於第一鼓風機105,第一鼓風機105所供給之空氣係由 其空氣吹出口而釋放出來。 回流管103之一端係插入於活性污泥槽101中。活性污 泥槽101中之處理水，係由於泵104而透過回流管103而 送入電解槽1 1 0中。此外，活性污泥槽1 01中處理水之上 澄液，係通過排出口 1 18而排出活性污泥槽101之外。 電解槽1 1 0係備有電極1 1 1及1 1 2時，這些電極係可以 由鐵或鋁所構成。電極111及1 1 2係接續於電裝置11 3上 時，由於電解而提供了電解槽110中之鐵或鋁離子。電解 槽110中電極111及112之下方，係配設有第二散氣管 114。第二散氣管114係接續於第二鼓風機106,經由第二 鼓風機1 06所供給的空氣，係由空氣吹出口而從電極1 1 1 及112附近釋放出來。第二散氣管114之下方係設有閥 1 1 5。閥11 5係設計成可以打開或關閉，通常係爲關閉狀態 ;如此，適當地開放閥Π 5而使得電解槽1 1 0之污泥或凝 集物排出到活性污泥槽1 〇 1中。 隔牆板1 07之不收容活性污泥的側面上，係安裝有磁石 -28- 1229657 五、發明說明（27) 107A。使用磁石107A可將（在電解槽1 10內凝集物中）含磷 化合物之凝集物有效地收集起來。 .本具體實施例中，由於磁石107A所吸附之含磷化合物之 凝集物並被收集起來，處理水內磷化合物則可成爲回收容 易形態而被收集起來。因而，現今缺磷之嚴重情事，則由 於本具體實施例之污水處理裝置，而使得高效率回收磷可 寄與厚望。 以上所說明的具體實施例之污水處理裝置，係設計有隔 牆板1 07，在第9圖所示污水處理裝置之活性污泥槽6 1之 沉澱槽67中，係設計了此種構成。 又且，若使用本具體實施例之污水處理裝置，視裝置之 規模而定，係可達成約90〜9 5%之高磷化合物去除率。 【具體實施例5】 其次，說明本發明之具體實施例5。 參照第1 4圖，本具體實施例污水處理裝置之全部構造， 係具有與第9圖所示污水處理裝置之構造相同之構造，與 第9圖污水處理裝置之相同的構元件，茲以同一編號參照 說明之。 本具體實施例污水處理裝置活性污泥槽6 1中之處理水， 係由泵64通過循環管63而送入離子供給槽70中。然後， 離子供給槽70之上澄液，係通過出流管76而送至沉澱槽 。然後沉澱槽67之上澄液，係從排出口而排出污水處理裝 置之外。 -29- 1229657 五、發明說明（28) 沉澱槽67內之出流管76，係設置有磁石67A。因而，在 離子供給槽70所生成磷化合物之凝集物，以及其他的從污 泥所分離出來之凝集物，可有效率地爲磁石6 7所吸附。如 此，在本具體實施例所使用之污水處理裝置中，具體實施 例4當可寄與更加高效率化地回收。 【具體實施例6】 參照第1 5圖，本具體實施例污水處理裝置之全部構造， 係與第13圖所示之污水處理裝置構造相同，當與第13圖 所示之污水處理裝置構成要素相同者，則以同一參照番號 表示之，且不再予以重覆說明。 本具體實施例之污水處理裝置係分割成··在隔牆板1 07 及150間收容從流入口 109流入之活性污泥的活性污泥槽 1 0 1區、電極1 1 1及1 1 2收納區及污泥1 08沉澱區。 從流入口 1 09所送入之處理水係收容於活性污泥槽內之 污泥收容區中，而該區域之上澄液則送到電極1 1 1及1 1 2 收納區。 在電極111及112收納區下方之處理水及凝集物，係送 到污泥1 08沉澱區，而該區域之上澄液則通過排出口 11 8 而排出到活性污泥槽101之外。 又，隔牆板150係在污泥108沉澱區之側壁面上設置磁 石150A。於是，磁石150A有效地吸附著在電極111及112 收納區生成磷化合物之凝集物，並且從其他的凝集物或污 泥所分離者亦爲磁石1 5 0 A有效地附吸附著。 -30- 1229657 五、發明說明（29) 排出到活性污泥槽外之處理水，較宜是送到另外設置之 厭氣濾床槽（收容厭氣性微生物之槽）。 至於含污泥108沉澱區之活性污泥槽1〇1，爲了使污泥 1 08送到活性污泥收容區，則其側壁係爲傾斜的。 【具體實施例7】 本具.體實施例之污水處理裝置，係爲具有其人孔與電極 爲一體化之形態之污水處理裝置。第1 6圖所示本具體實施 例之污水處理裝置，茲與第1圖所示之污水處理裝置比較 ，其係變更了人孔28與電極41及42週邊部份之構成，當 與第1圖所示之污水處理裝置構成要素相同者，則以同一 參照番號表示之，且不再予以重覆說明。 參照第1 6圖，在污水處理裝置之上部係爲複數個人孔 28所覆蓋。又，人孔28係安裝有通過絕緣體400之電極 41及42。在此，茲參照第17圖來說明電極41及42之絕 緣體400之安裝態樣。 在本具體實施例污水處理裝置之人孔28中，係安裝有通 過絕緣體400之電極41及42。詳細言之，電極41及42 係由螺栓等固定而安裝於絕緣體400上。於是，電極41及 42所安裝的絕緣體400，係由螺栓等固定而安裝於人孔上 。於是，在電極41及42所接續之各種連接器402，係接 續到電源裝置38上。因此，作業員可在地面上並不需要進 入地下，以人孔28之把手28A來操作人孔28使之御下， 而在地面上取出電極41及42。因此，關於電極41及42 -31 · 1229657 五、發明說明（3〇 ) 之維護，在手段上，比起其他之污水處理裝置，本具體實 施例之污水處理裝置係較爲容易。 本具體實施例之污水處理裝置，其構成爲電極41及42 係浸沒於處理水中，而絕緣體400則不浸入處理水中。又 ’絕緣體400內兩端均備有可收容接續線之連接器；連接 器之一端爲接在電源裝置38上，連接器之另一端則接續於 電極41或42上。因此，可以避免電極41及42與電源裝 置38之接續部份浸沒於處理水中。而且，得以避免該接續 部份受到腐蝕作用。 又，安裝於人孔28上之電極41及42，以及污水處理裝 置之電極41及42之位置考量，與其他實施例電極的位置 比起來，本具體實施例並不會顯得比較高。由於電極4 1及 4 2之位置不是在咼處，電極4 1及4 2係浸沒於處理水中， 電極41及42在外加電壓時，並不供給鐵離子或鋁離子。 因此’本具體實施例’在檢測部3 0 8 A設有監控電極41及 42間電壓値之監控器，來判斷電極41及42是否浸沒於處 理水中。於是’本具體實施例污水處理裝置中電極41及 42之電壓値’係顯不出電極41及42是否浸沒於處理水中 之値，較宜是備有警報裝置。 【具體實施例8】 在第1 8圖所不之污水處理系統中’與具體實施例1所說 明的污水處理系統（參照第1圖）具相同符號者，則不再予 以重覆說明。又且’第19圖乃是省略了示於第18圖一部 •32- 1229657 五、發明說明（μ ) 份組件所作成之圖。 參照第1 8圖及第1 9圖，本具體實施例之污水處理系統 ’主要係由槽200所構成。槽200之內部係由第一隔牆2 、第二隔牆3、第三隔牆4及第四隔牆20，第一厭氣濾床 槽5、第二厭氣濾床槽1 〇、接觸曝氣槽1 4、沉澱槽1 9及 消毒槽21所區畫之區域。再者，本具體實施例之槽200係 設計用來代替示於第1圖槽1中之第三輸送管29及第一泵 18時，第三隔牆4之下端則將槽200之底部予以隔離。因 此，於槽200而在接氣曝氣槽1 4經喜氣分解之處理水，係 供給到沉澱槽1 9。 第一散氣管1 6之上端係接續於第一鼓風機1 7。又，第 一散氣管16之下端，如以下所述.，其係設計在接觸曝氣槽 1 4底部周圍之數個內側之一邊上（參照第19圖）。在第一 散氣管1 6之底面側上，係形成複數個孔（孔1 6a，參照第 19圖）。於是，由第一鼓風機17所送出之空氣，係由該孔 而將該空氣釋放出來。又，由於在第一散氣管1 6底面側所 形成之孔，亦且在其上面或側面上形成孔之場合下，污泥 均難以進入到其內部。 在接觸曝氣槽14之底部係備有泵133。再者’在泵133 之頂部係接到污泥迴流管1 34，延伸到圖左側之污泥迴流 管134之頂端則係接到污泥迴流管135。於是’接觸曝氣 槽1 4所生成之污泥乃送到第一厭氣濾床槽5。 在第18圖槽200中之沉澱槽19與第一厭氣濾床槽5， -33- 1229657 五、發明說明（32 ) 係通過第一迴流管24而接通。第一迴流管24之內部係備 肯第二散氣管25。第二散氣管25係接續於第二鼓風機26 ，並且形成以噴出該空氣爲目的之噴出孔。於是，由第二 鼓風機26所供給之空氣，係由在第二散氣管25所形成之 噴出孔噴出，沉澱槽19內之處理水係通過迴流管24而送 到第一厭氣濾床槽。 又’在接觸曝氣槽14之頂部，係設有包括電解單元之盒 套54。詳細來說，盒套54係由4個垂直的板體所接合而 成的中空體。在盒套54之內側中，係設有電極對51及52 。各個電極對51及52係接到電源57上。再者，盒套54 之內部中係設有第三散氣管53。第三散氣管53係接續到 第四鼓風機56上。 盒套54內行電氣分解反應（適當的，簡稱爲電解）之電極 對5 1及52，係有鐵離子或鋁離子等金屬離子溶出。因此 ，在接觸曝氣槽1 4中，溶出的金屬離子與處理水中磷化合 物反應，乃形成水難溶性金屬鹽類而被凝集起來。金屬離 子和磷化合物反應之實例，係如上記所示之式（4 )。 其次，參照第20圖及第21圖來說明本具體實施例中電 解單元之構成。第20圖係爲電解單元之斜視圖。又，第 2 1圖係爲電解單元之分解斜視圖。 盒套54上端之四個固定位置，係備有爲安裝組件541、 5 42、5 43及5 44。另外，盒套54係由在其內部之隔牆板 5 40而隔成左右兩個空間。因此，第三散氣管53係從盒套 •34- 1229657 五、發明說明（33) 54之上方而向下導入。第三散氣管53則在盒套之底部由 右向左延‘伸。 電極對51及52係備有兩枚相向之電極511、512、521 及522。於是，電極對51及52之該相向的兩枚電極之頂 端，係安裝於電極支撐體510及5 20上。另外，電極對51 及52之各個電極係通過連接器513及523而接續到電源 5 7 (參照第1 8圖）上。 於電極支撐體510及520之兩端係分別由安裝組件541 、5 42、5 43及544而安裝之；而電極511及512係設置在 隔牆板540之右側，電極521及522係設置在隔牆板540 之左側。電極511及512間之電解反應係在隔牆板540之 右側上進行.，電極521及522間之電解反應係在隔牆板 540之左側上進行。 又且，第三散氣管53所放出之氣泡，另外，該氣泡則衝 擊盒套54之內壁，而在盒套54內生成對流。因此，在電 極511、512、521及5 22附近可有效率地供給處理水。依 照第三散氣管53,則構成了本具體實施例在盒套所圍空間 內達成攪拌目的之攪拌手段。另外，由於第三散氣管53中 空氣釋出裝置係爲有限，因之就攪拌手段言，較宜於盒套 54內之水中混入攪拌子等裝置。 此外，由於上述電解反應溶出金屬離子，與處理水中之 磷化合物起反應，因而形成水難溶性金屬鹽類。一方面， 盒套54係爲如以上所述之中空體。更且，盒套54爲無底 -35- 1229657 五、發明說明（34) 之形狀。然而，在此所生成之金屬鹽類，由於其自重之故 而加速地導入接觸曝氣槽14中。 以上所說明之本具體實施例之電解單元，係設計有接觸 曝氣槽14。又，電解單元係較宜設計在槽200內之第一厭 氣濾床槽5、第一厭氣濾床槽1 0、或沉澱槽1 9等其他槽中 。本具體實施例之沉澱槽1 9，係構成沉澱污泥之沉澱槽。 更且，電解單元宜設計有鄰接於槽2 0 0外部之流入口 6或 排水口 2 3。 此外，槽200之迴流量爲3Q。又，所謂的Q係指流入槽 200之流入水量。於是，在槽200內係以流入水量之3倍 水量來循環。 此外，電極對51及52起電解反應所溶出之鐵離子或鋁 離子之濃度，係以處理水中磷之溶積莫耳濃度之1〜3倍來 進行。另外，上述電解反應之鐵離子或鋁離子之濃度，較 宜爲控制爲處理水中磷之溶積莫耳濃度之1〜2倍，更宜控 制在處理水中磷之溶積莫耳濃度之1 · 5倍之程度。因此之 故，施用於電解反應電極上之電流密度，應控制在0 . 1毫 安培/平方公分以上，而在多數場合下，應控制在0.3毫安 培/平方公分以上之程度。 因此，爲了控制電極上之電流密度之目的，則應防止在 電極表面上生成氧化物膜或有機性附著物；並且，應考慮 除去該等氧化物膜或有機性附著物。在電極之陽極側上所 生成之水氧化鐵或有機性附著物，應考慮到其會因發生在 -36- 1229657 五、發明說明（35) 陰極側氫氣或由於第三散氣管53曝氣所去除。然而，當上 述之電解反應係在低電流密度之場合下進行時，在陰極側 所發生的氫氣量係爲十分的低，則不能考量在電極之陽極 側上所生成附著物會被除去。又，電解單元中所使用之第 三散氣管53之曝氣量，係爲15升/分鐘之程度。 例如，生活污水流入槽200之日流量爲1 200升，在槽 200內各槽間之循環流量爲6000升之場合下，則在電極 511和512以及電極521和522間流通之電流係控制在650 毫安培之程度。各電極所施用之電流密度，端賴各電極之 浸水面積變化而加以控制之。又，在電極511和512之間 隔以及電極521和522間之間隔，通常係爲25毫米之程度 ，而電極間之電壓則時常監控之。再者，各電極之極性， 較宜依預定之時間（例如24小時）而使之反轉較佳。 【具體實施例9】 第22圖之污水處理系統係從示於第18圖之污水處理系 統，變更其電解單元之配置，並且加上數個該構成要素所 得到的。然而，於第22圖中之與第18圖相同之構成要素 ，則賦予相同符號並不再重覆說明之。 參照第22圖，第一厭氣濾床槽5之上方，係設置有包括 電極對51及52之電解單元。 又，在沉澱槽19中備有第三輸送管38及泵39。接觸曝 氣槽1 4內之處理水係通過第三輸送管38而流入沉澱槽1 9 中。再者，此種流動係可由泵38而促進之。 -37- 1229657 五、發明說明（36) 電極對51及5 2係配置於電解槽5 9中。電解槽5 9則接 續於第一迴流管24。因此，沉澱槽1 9內之處理水乃通過 第一迴流管24而導入電解槽59中。 在電解槽59之左上部，係備有排出管592。導入電解槽 59中處理水之上澄液，乃通過排出管592而流達第一厭氣 濾床槽5。 再者，在電解槽59之底部係備有排出口 591。更且，第 一厭氣濾床槽5內設置有磷回收單元，其係位於電解槽5 9 之下方而鄰接於電解槽59。 依據具體實施例8說明之，電解槽5 9內電極對5 1及5 2 係行電解反應而生成金屬離子，該金屬離子乃與處理水反 應而成爲難溶性金屬鹽類。該難溶性金屬鹽類由於自重， 乃通過排出口 5 9 1而導入磷回收單元1 60。於是，利用磷 回收單元1 60而將該難溶性金鹽類選擇性地回收。 第23圖所示者爲磷回收單元160之斷面圖。磷回收單元 160係包括本體164、網162和163以及吸附材165。吸附 材165係用來吸附上述之難溶性金屬鹽類中較細微者，其 係配置於網162和網163間，其係由活性碳或陶磁所構成 。在電解槽5 9中之處理水及金屬鹽類，係經由網1 6 2和 163而導入本體164中。本體164之上澄液，係通過在本體 1 6 4外之輸送管1 6 1排出到第一厭氣濾床槽5內。 依據以上所述，本具體實施例之磷回收單元160係設計 在與電解單元相對之下游側，並且鄰接於電解單元。因而 -38- 1229657 五、發明說明（37) ，電解槽59所生成之難溶性金屬鹽類，乃集中於磷回收單 元160本體164之底部，而爲吸附材165所吸附。總之， 本具體實施例污水處理系統之難溶性金屬鹽類，並不與污 泥混合即被回收。又且，由於備有吸附材1 65，而得以回 收微細的難溶性金屬鹽類，亦且向上提昇了該金屬鹽類之 回收效率。 本具體實施例之電解單元及磷回收單元160,係設計在 第一厭氣濾床槽5中。另外，電解槽係較宜設計成槽1內 第二厭氣濾床槽1 0、接觸曝氣槽1 4或沉澱槽以外之其他 槽。但是，本具體實施例之電解單元及磷回收單元160, 於其係設計在具有共污物去除槽之第一厭氣濾床槽5之場 合下，則磷回收單元160乃發揮出十分顯著之效果。在不 具有電解單元及磷回收單元160設計之第一厭氣濾床槽5 之場合下’雖然電解單元係設成相同條件之其他槽之場合 ’則該將預料得到難溶性金屬鹽類單品之回收係很困難的 〇 【具體實施例10】 首先’參照第24圖，生活污水最初係導入沉澱分離槽 601。在沉澱分離槽601中，主要係將污水進行厭氣分解。 沉澱分離槽601內之污水係導入回轉接觸槽602。回轉 接觸槽602主要係使污水進行喜氣分解。之外，在回轉接 觸槽602中’係使用可回轉之供喜氣性微生物增殖用之喜 氣濾床。 -39- 1229657 五、發明說明（38) 回轉接觸槽602內之污水係導入沉澱槽603。沉澱槽603 係設計成可分離包括在污水中之污泥及液體。此外，沉澱 槽603中所沉澱之污泥，係以周知的方法而移送至沉澱分 離槽601。 沉澱槽603內之污水係導入中間流量調整槽604。中間 流量調整槽604乃是爲了調整導入後述電解槽605之污水 流量而設計的。 中間流量調整槽604內之污水係導入電解槽605。電解 槽605乃是污水中預定成分與反應性金屬離子發生電極之 電氣分解之槽。此外，電解槽605之詳細構造，說明如下。 電解槽605內之污水係導入凝集槽606。凝集槽606主 要是爲了使在電解槽605.所產生之金屬離子，與污水中預 定成分起反應而形成膠羽所設計的。總之，在凝集槽606 內，金屬離子與污水中預定成分起反應。例如，鐵離子溶 出之電解反應之場合下，預料得到其係遵從前述式（4 )之反 應所生成的。 再者，凝集槽606內之污水，係同時與上述反應結果所 生成之膠羽一起導入凝集沉澱槽607。凝集沉澱槽607乃 是爲了使凝集槽606所生成的膠羽沉降而設計的。 凝集沉澱槽607內之污水係導入消毒槽608中。消毒槽 608係備有氯系等葯品。該在消毒槽608中之葯品，乃是 爲了消毒污水而設計的。從而，消毒槽608內之污水乃放 流至河川等。另外，雖然在污水中存在有之磷、磷酸或有 -40- 1229657 五、發明說明（39) 機磷，但是從消毒槽608所放流污水之總磷濃度係爲1毫 克/升。 在第24B圖所示之處理法，係設計成以凝集槽615來替 代示於第24A圖之電解槽605及凝集槽606’在該凝集槽 615內係產生金屬離子，而且，該金屬離子與污水中預定 成分起反應並形成膠羽。 此外，於第24A圖及第24B圖中，沉激分離槽601、回 轉接觸槽602以及沉澱槽603係爲虛線R所圍。虛線R所 圍之範圍並不進行處理，其較宜變更爲如第25圖所示。 參照第25圖，沉澱分離槽601內之污水係導入接觸曝氣 槽620。接觸曝氣槽620中主要由喜氣性細菌而使得污水 進行喜氣分解。此外，接觸曝氣槽620係不同於回轉接觸 槽6 02 (參照第24A圖及第24B圖），喜氣濾床並不品轉。 接觸曝氣槽620內之污水，係導入沉澱槽603。另外， 於接觸曝氣槽620中，由於曝氣而剝離之附著於喜氣濾床 之污泥或生物膜，係利用周知的方法，而將之移送至沉澱 分離槽601及沉澱槽603。 以下，茲利用遂行示於第24 A圖流程圖所示處理法爲目 的之裝置’來展示本發明之具體實施例10。此外，茲利用 遂行示於第24B圖流程圖所示處理法爲目的之裝置，來展 示本發明之具體實施例1 1，詳如下述。 本具體實施例之凝集沉澱裝置，其至少包括第24A圖所 示之電解槽605、凝集槽606及凝集沉澱槽607。 -41 - 1229657 五、發明說明（4〇) 第26圖所示者，係爲本具體實施例包括合倂淨化裝置之 凝集沉澱裝置之一部份外觀圖。污水係從預定水槽，通過 配管1 1而導入中間流量調整槽604內。再者，污水係由中 間流量調整槽604，通過配管12而導入電解槽605中。更 且，污水由電解槽605，通過配管13而導入凝集槽606。 再者，（雖然圖中省略）由凝集槽606來之污水，係通過預 定配管而導入凝集沉澱槽607。於凝集沉澱裝置中，污水 在各槽之停留時間，（例如）係隨各槽容積之調整而調整。 第27圖所示者爲第26圖之電解槽605之分解斜視圖。 電解槽605主要係由筐體650、電極固定板、複數個電極 對以及蓋所構成。 筐體650係受筐體支撐體600所支撐著。再者，污水流 入孔650A及污水流出孔650B乃形成於筐體650之側面。 污水係從污水流入孔650A流入，並從污水流出孔650B流 出筐體650。 在筐體650之內部係配有散氣管654。散氣管654係從 筐體650外部之預定的泵而將空氣導入。另外，散氣管 6 54較宜形成小孔。因此，氣泡係由筐體650內部之散氣 管654釋放出來。 電極固定板653及電極對651係收納於筐體650內。電 極對係分別包括支撐體7 1 0，該支撐體7 1 0上係分別安裝 有2枚板狀之電極711及712。爲了使電極711及712插 在電極固定板653上，乃於其上形成孔731〜736。在筐體 -42- 1229657 五、發明說明（41) 650內，由於供電極711及712插在電極固定板653上之 孔731〜7 36，而使得各電極對651之支撐體710相接於電 極固定板653上面。各電極對651係備有使電解槽605外 部電源接續到電極7 1 1及7 1 2爲目的之連接器7 1 9C。 電極對651與收納於筐體650上面之電極固定板6 5 3係 爲蓋652所覆蓋。 電極711及712之任何一者，其均可由鐵或鋁等金屬所 構成。於是，電解槽605中，由於各電極對651之電極 7 1 1及7 1 2之任何一者行電氣分解（較宜以電解簡稱之）反 應，而在污水中供給了鐵離子或鋁離子等金屬離子。當電 極對651係收納於筐體650時，電極711及712表面之附 著物，乃由在散氣管小孔上所釋出之氣泡所除去。 在此，茲參照第28圖及第29圖來詳細說明電極對651 之構造。第28圖係爲電極對651之斜視圖。又，第29圖 爲截取電極對65 1之一部份之斜視圖。 電極對651係包括電極711及712之2枚金屬板。該金 屬板（例如）係由鐵或鋁所製成的。再者，電極對651係包 括支撐體710。支撐體710之頂部係安裝有把手71 0A。支 撐體7 1 0之左側面則安裝有封蓋7 1 3。詳細來說，於封蓋 7 1 3上係形成了 6個螺絲孔，由於各別之螺絲孔以預定螺 絲固定，而使得封蓋7 1 3能安裝在支撐體之左側面上。 由於螺母711A及711B而使得電極711能固定在封蓋 7 1 3上。又，上述之螺絲孔，其係包括了螺絲孔7 1 3 A、 -43- 1229657 五、發明說明（42) 713B (參照第30圖）、713C、713D及713E。另外，以上所 述之預定的螺絲，係包括了示於第30圖之71 7A、71 7B、 717C 及 717D。 在支撐體頂部後方係安裝有導桿7 1 9D，配線7 1 9係從導 桿71 9D向支撐體710之上方突出。導桿71 9D係成圓筒狀 ，配線7 1 9係通到導桿7 1 9D之內部。配線7 1 9之一端係接 續到連接器71 9C上。 配線7 1 9之從導桿7 1 9D前端（下方）部份到另一端爲止， 係內藏於支撐體與封蓋7 1 3之組合體中。又，配線7 1 9係 內包有複數條配線（包括以下所述之配線7 1 9 A )。於是，配 線7 1 9之內包有複數條配線之另一端，係成爲安裝於下述 端子71 8(參照第30圖）等端子上之狀態。 在此於第30圖及第3 1圖上所示者，係爲截取電極對 651之一部份之分解斜視圖。又，爲了方便起見，在第31 圖上係省略了配線7 1 9、連接器7 1 9C、配線7 1 9A及端子 718。 參照第30圖及第31圖，封蓋713與支撐體710間，係 備有鐵或鋼等所製成之固定電極用器具715及716。固定 電極用器具715及716係爲導體，較宜由抗腐蝕材料所構 成。 固定電極用器具715係爲具有突出部7 15A及715B之板 體。突出部71 5A及71 5B係由具有貫穿封蓋713之孔所構 成。電極7 1 1之安裝，係由螺母7 1 1 A和7 1 1 B、突出部 -44- 1229657 五、發明說明（43) 71 5A及71 5B而與電氣相接續。 支撐體710之中央稍後方，在固定電極用器具715與固 定電極用器具7 1 6間，係備有端子7 1 8。端子7 1 8係由配 線719A之末端所構成。配線719A係內包有複數條配線之 配線7 1 9中之一。 端子718係以固定電極用器具715而安裝於封蓋713上 ’並且當封蓋713係安裝於支撐體710上時，係配置有與 突出部7 1 5A接觸之位置。因此，電極71 1係通過突71 5A 和端子7 1 8而與電氣接續。 此外，固定電極用器具716亦形成與突出部71 5A及 71 5B同樣之突出部。該突出部係突出於支撐體710之左側 面上。另外，支撐體710之中央稍前方，在固定電極用器 具7 1 5與固定電極用器具7 1 6間，係備有所謂端子7 1 8之 另一端。在此所稱之另一端子，係指內包有複數條配線之 配線7 1 9中之有別於配線7 1 9 A之配線之末端所構成。於是 ，此種其他的端子係以在固定電極用器具7 1 6之突出部而 與電氣相接續，該突出部係接續於電極7 1 2。因之，該其 他的端子乃電氣接續於電極7 1 2。 雖然省略了圖示，但是在固定電極用器具715與固定電 極用器具7 1 6間，該端子與端子7 1 8間係備有絕緣體。因 此，在支撐體710與封蓋713組合之內部，得以確實地避 免了電極711與電極712間發生短路。 固定電極用器具71 5係以螺母714A、714B及714C而螺 -45- 1229657 五、發明說明（44) 栓固定於封蓋713上。又且，固定電極用器具716係以螺 母714D、714E及714F而螺栓固定於支撐體710上。 .在支撐體7 1 0與封蓋7 1 3間，於封蓋7 1 3螺栓固定場所 之外側，係設有墊片710B。又，在支撐體710與固定電極 用器具7 1 6間，於固定電極用器具7 1 6螺栓固定場所之外 側，係設有墊片710C。更且，在封蓋713與固定電極用器 具7 1 5間，於固定電極用器具7 1 5螺栓固定場所之外側， 係設有與墊片7 1 0C同樣之墊片。 因而，在支撐體710與封蓋713組合之場合下，係不會 有水進入到支撐體710與封蓋713之內部，而可內藏端子 7 1 8及上述之其他的端子。 備有電.極對651之電解槽.605,係會提供如以上所述那 樣的金屬離子。於電解槽60 5所供給的金屬離子，係與污 水共同送到凝集槽606中。 在電解槽605所產生之金屬離子，係在凝集槽606與污 水起反應。在凝集槽606中，金屬離子與污水起反應而形 成了磷金屬鹽類等膠羽。此膠羽係與污水送至凝集沉澱槽 607中，而在凝集沉澱槽607中沉降。 以上所說明之本具體實施例，於凝集槽606中經除去氮 處理後之污水與金屬離子起反應，並具有以供該反應所生 成之沉澱物凝集用之第一槽60之構成。再者，在凝集沉澱 槽607中並具有供從第一槽導入之污水、第一槽物凝集物 沉降用之第二槽。總之，電解槽605係由因電極之電氣分 -46- 1229657 五、發明說明（45) 解而供給第一槽金屬離子之電解槽所構成。 以上所說明之本具體實施例，與污水起反應之金屬離子 ，係由電極之電解反應所供給的。因此，與添加凝集劑到 污水中而供給金屬離子之場合相比較之下，依照本發明所 供給之金屬離子，係具有安全上之優點。凝集劑、爲了凝 集所添加之pH調整劑、以及酸性或鹼性葯劑均會造成危險 〇 再者，與在污水中添加凝集劑之場合相比較，並不需要 調整污水之pH値，則污水容易地與金屬離子起反應，此亦 爲本發明之優點。 更且，與在污水中添加凝集劑之場合相比較，不需要儲 存凝集劑之空間，此亦爲本發明之優點。 另外，電極對進行電解反應，所溶出之鐵離子或鋁離子 之濃度，係爲處理水中磷之容積.莫耳濃度之1〜4倍。又， 上述電解反應中鐵離子或鋁離子之濃度，宜控制在處理水 中磷之容積莫耳濃度之2. 5〜3.5倍之程度，更宜控制在 3.0倍之程度。爲後達到此目的，電極行電解反應之電流 密度，應控制在0 . 1毫安培/平方公分以上，在多數場合下 ，會控制在0.3毫安培/平方公分之程度。 因此，由於控制了電極之電流密度，則預料得到在電極 表面生成氧化物膜或有機性附著物乃得以防止，並且會將 之除去。在電極之陽極側所生成之可預料得到之水氧化物 膜或有機性附著物，將可預測得到其會因在電極之陰極側 -47- 1229657 五、發明說明（46) 所生成之氫氣，或是因散氣管654之曝氣而將之除去。然 而，在上述電解反應之電流密度爲低的場合下，在電極之 陰極側所生成之氫氣係爲低的，可預料得到其並不能除去 在陽極側所生成之附著物。又，電解單元中，散氣管654 之曝氣量爲15升/分鐘。 例如，包括合倂淨化槽之凝集沉澱裝置，其生活污水之 日流量爲1 0噸之場合下，在電極7 1 1和7 1 2間流通之電流 係控制在1 2 · 3安培之程度。於是，在電極對6 5 1之電解反 應，所產生之鐵離子或鋁離子之濃度，可預料得到其係爲 處理水中磷之容積莫耳濃度之3.0倍。各電極所施用之電 流密度，端賴各電極之浸水面積變化而加以控制之。又， 在各電極對651中電極711和712間之間隔，通常係爲25 毫米之程度，而電極間之電壓則時常監控之。再者，各電 極之極性，較宜依預定之時間（例如24小時）而使之反轉較 佳。 凝集槽606中污水之停留時間，通常係在20分鐘以上。 又，凝集沉澱槽607中污水之停留時間，通常係在3小時 以上。 於是，本具體實施例中，凝集槽605中污水之停留時間 ，宜爲3分鐘以上。此等所用停留時間之條件，係基於電 解槽停留時間決定試驗之結果而定。上述之試驗，說明如 下。 【電解槽停留時間決定試驗】 -48- 1229657 五、發明說明（47) Π試驗方法 在不曝氣下，使人工配製液在預定時間進行鐵之電氣分 解後’該人工配製液移到沉降測定器（參照第32圖）中，以 求得此人工配製液在各種深度下之磷去除率。 人工配製液乃爲與通常所導入凝集槽615中之污水具有 同樣的組成’經由人工配製所合成之人工配製液。人工配 氣:液之組成係如表1所示。 又’本試驗之人工配製液中鐵之電氣分解，係使用3升 及4升之電解槽，各電解槽係以3 . 5升/分鐘之通風量來進 行曝氣。此電氣分解，由於控制了電極中所流通之電流量 ’因而控制了在人工配製液中鐵之莫耳數。例如，爲了使 在人工配製液中鐵離子之莫耳數係爲磷莫耳數之約2 . 5倍 及約3 · 0倍，則各電解槽中電極所流通之電流量係分別爲 1 · 3 0安培和1 · 5 5安培。 參照第32圖，沉降測定器700係爲筒狀，其主要係由收 容溶液之收容部790所構成。 再者，在收容部790之側面，係備有可抽出於收容部 7 90各種深度所存在的溶液之溶液抽出部791〜796。溶液抽 出部791、792、79 3、794、795及796，係分別可抽出自 水面起爲0.3米、0.5米、0.7米、0.9米、1.1米及1.3 米深之溶液。 2 )試驗結果 在第33圖之電解槽37中，進行鐵之電解3分鐘後，將 -49- 1229657 五、發明說明（48) 該電解槽之人工配製液移到沉降測定器中’使之進行 快速攪伴（以150i.pm攪伴10分鐘）及慢速攪拌（以60rPm攪 伴1 0分鐘），而測得在沉降測定器700之各種深度下磷之 去除率。又，此次3分鐘之電解，其電極之通電量係控制 在使得其所溶出鐵離子之莫耳數，係爲在人工配製液中磷 莫耳數之約2 . 5倍。 在第33圖中·係表示在沉降測定器700中之凝集物，於 沉降時間爲1 . 5小時之場合下磷之去除率。於是，在第3 3 圖中▲、國係分別表示凝集物於沉降時間爲3 . 0小時、4 . 0 小時之場合下磷之去除率。又且，以下第33〜36圖中，❿ 、▲及係分別表示凝集物於沉降時間爲1 . 5小時、3 . 0 .小時及4 · 0小時之場合下磷之去除率。 磷之去除率Rp係指在人工配製液中磷之初期濃度爲Cs ’經過一段沉降時間後，在人工配製液中於各個深度下磷 之濃度爲Cd時，藉由下式（5)所計算出來之値。 Rp二{(Cs-Cd

The first air diffusing pipe 16 is connected to the first blower 17 ' and the air supplied from the first blower 17 ' released through the air blowing outlet ' enables the contact aeration tank 14 to maintain a happy state. Therefore, the treated water in the contact aeration tank 14 is decomposed aerobicly by the aerobic microorganisms, and at the same time, the ammonia nitrogen is decomposed into nitrate nitrogen by the nitrifying bacteria. Generally, the so-called nitrifying bacteria refers to ammonia oxidizing bacteria and nitrous bacteria. The biofilms attached to the contact material 15 multiply slowly. Therefore, the air supplied from the first air blower 17 from the first air diffusing pipe 16 and the air blowout port from the air of the first air diffusing pipe 16 release the air, so that the biofilm attached to the contact material 15 is peeled off. The sedimentation tank 19 is the range defined by the third partition wall 4 and the contact aeration tank 14. Around. Third duct 29. It is connected to the first pump 18, and when the first pump 18 is in operation, the supernatant liquid of the aerobic decomposition process water contacting the aeration tank 14 is supplied to the sedimentation tank 19 through the communication port 20. The communication opening 20 runs through the top of the third partition wall 4. The clear liquid on the sedimentation tank 19 flows into the disinfection tank 21. Inside the sterilizing tank 21, a sterilizing device 22 is provided. Inside the sterilization device 22, a chlorine-based chemical is provided to disinfect the treated water flowing from the sedimentation tank 19. Thus, the sterilized treated water is discharged into the drainage outside the tank 1 through the drainage port 23. The first return pipe 24 is a pipe that connects the precipitation tank 19 and the electrolytic tank 37. The second air diffusing pipe 25 arranged in the first return pipe 24 forms a plurality of air blowing outlets, and is connected to the second blower 26. Therefore, the sedimentation tank • 16-1229657 V. Description of the invention (15) 19 The amount of the upper liquid is transferred to the electrolytic tank 37 through the first return pipe 24. Electrodes 41 and 42 are arranged in the electrolytic cell 37. Below the electrodes 41 and 42, a third air diffusing tube 40 is provided. The third air duct 40 forms a plurality of air outlets, and is connected to the fourth blower 39. Therefore, the air sent from the fourth blower 39 is discharged from the air outlet of the third air diffuser 40, so the fixation caused by the biofilm or nitrate ions on the surfaces of the electrodes 41 and 42 is removed. Film of film. Furthermore, in order to effectively remove the film of the electrodes 41 and 42 from the air blown out by the third diffuser pipe 40, it is preferable that the electrodes 41 and 42 are provided near the wall surface of the electrolytic cell 37. The treated water in the electrolytic tank 37 is discharged through the discharge port 47 to be discharged from the first anaerobic bed tank 5. Next, a lid 36 is provided on the discharge port of the electrolytic cell 37. The cover 36 is connected to the floating ball 35. In addition, a water level sensor 48 for detecting the water level of the first anaerobic filter bed tank 5 is provided near the cover 36. The electrodes 4 1 and 42, the water level sensor 48 and the fourth blower 39 are connected to the power supply device 38. The electrodes 41 and 42 are made of, for example, iron or aluminum. In order to make either one of the electrodes 41 and 42 a + pole and the other one, a voltage is applied to the power supply device 38. Therefore, in the case of the electrodes 41 and 42 composed of iron, the electrolytic reaction system of + and-poles is expressed as: + pole: Fe _► Fe2 + + 2e a · ·. (1) One pole: 2H + + 2e--► Order * ·· (2) -17- 1229657 V. Description of the invention (16) Furthermore, the divalent iron produced by the + pole becomes trivalent due to air oxidation. iron. Once the electrodes 41 and 42 are composed of aluminum, the reaction of one pole does not change, but the electrolytic reaction of + pole is expressed as the following formula (3): + pole: A1 -► Al3 + + 3e '--- ( 3) In the following, the specific embodiment will be described with the electrodes 41 and 42 made of iron. With the exception of specific combinations, the iron system may be changed to aluminum in all points of view. The trivalent iron ion (Pe3 +) generated in the oxidation reaction of the electrolytic reaction of formula (1) is used for aggregating the phosphorus compounds in the treated water returned from the first reflux pipe 24. In addition, the phosphorus compound agglomerated with Fe3 + is used, and its main reaction formula is shown in formula (4): P〇43-+ Fe3 + -► FePO | · ·. (3) A valve 43 formed at the bottom of the electrolytic cell 37 is used to remove agglomerates or sludge in the electrolytic cell 37 from the electrolytic cell 37. When the valve 43 is opened, the aggregate or sludge in the electrolytic tank 37 moves to the first anaerobic filter bed tank 5. FIG. 2 is a detailed structural diagram of the electrolytic cell 37 and its vicinity. Referring to Fig. 2, the treated water returned from the first return pipe 24 flows into the electrolytic tank 37 from the inlet of the electrolytic tank 37. A third diffuser 40 is provided near the electrodes 41 and 42. The air in the vicinity of the electrodes 41 and 42 is supplied by the third air diffusing pipe 40. A cover 36 covering the discharge port 47 is connected to the float 35. In addition, the cover 36 is connected to the lower end of the discharge port 47 with a hinge 34 so that the discharge port 47 can be repeatedly opened and closed. Therefore, the water level of the first anaerobic filter bed tank 5, -18-1229657 V. Description of the invention (彳 7) When the cover 36 is open, when the water level is 100A, the first anaerobic filter bed tank 5 The solution inside does not flow into the electrolytic tank 37 through the discharge port 47; when the water level is 100B, the solution in the first anaerobic filter bed tank 5 flows into the electrolytic tank 37 through the discharge port 47. When the water level of the first anaerobic filter bed tank 5 is 100A, the float 35 is at the position shown by the symbol 35A in the second figure; and the cover 36 is shown by the symbol 36A; The 47 series is open. On the other hand, when the water level of the first anaerobic filter bed tank 5 is 100B, the floating ball 35 is at the position shown by the symbol 35B in the second figure; at this time, the discharge port 47 is closed. Therefore, in this specific embodiment, the discharge port 47 is covered by the cover 36, and the cover 36 connected to the floating ball can surely prevent the domestic sewage flowing from the inflow port 6 from mixing into the dross and avoiding its direct flow into the electrolysis In slot 37. The above-mentioned water level 100A is the water level at which the solution in the first anaerobic filter bed tank 5 flows into the electrolytic tank 37, and also includes the water level in which the scum and the like in the solution do not flow into the electrolytic tank 37. A control member as shown in the figure is provided in the electrolytic cell 37. The control parts are the opening and closing of the control valve 43, the current flowing through the electrodes 41 and 42, the voltage between the electrodes 41 and 42, the amount of air blown by the third diffuser 40, and the voltage applied to the electrodes 41 and 42. The polarity and so on. The water level sensor 48 is designed to monitor the water level of the first anaerobic filter bed tank 5 to reach a predetermined water level. The output force detected by the water level sensor 48 is the input force of the aforementioned control member. Here, the predetermined water level is (-19 * · 1229657 V. Description of the invention (18) For example) The domestic sewage flowing from the inlet 6 directly flows to the water level in the electrolytic cell 37. Therefore, when the water level reaches a predetermined water level and is detected by the sensor 48, the control unit issues a warning indicated by a sound or the like. In the structure of these controls, since the inflow of water discharged through the discharge port 6 is adjusted, the domestic sewage flowing in through the discharge port 6 does not directly flow into the electrolytic tank 37, so scum can be reliably prevented from flowing into the electrolytic In slot 37. In addition, the predetermined water level is the water level at which the solution in the first anaerobic filter bed tank 5 flows into the electrolytic tank 37, and also the water level at which the scum in the solution does not flow into the electrolytic tank 37. The maintenance personnel who carry out the sewage treatment system of this specific embodiment determine whether the domestic sewage flowing from the outlet 6 directly flows into the electrolytic tank 37 depending on whether the above-mentioned warning is generated. Therefore, when the cover 35 and the floating ball 36 are not provided, it is possible to easily determine the necessity of sweeping the electrodes 41 and 42 by determining whether scum is accumulated near the electrodes 41 and 42 according to the presence or absence of a warning. In addition, when the water level sensor 48 detects that the predetermined water level has been reached, the controller will control the increase of the air supply amount of the third diffuser pipe 40. The control means for performing such control, even when the scum flows into the vicinity of the electrodes 41 and 42, when the amount of air supplied from the third diffuser increases, the scum is discharged out of the electrolytic cell 37. Therefore, accumulation of scum near the electrodes 41 and 42 can be reliably prevented. In short, the specific embodiment described above is equipped with at least a combination of a float 35 and a cover 36, or any one of the water level sensor 48, -20-1229657 V. Description of the invention (19) Therefore, The accumulation of scum near the electrodes 41 and 42 is avoided. The electrodes 41 and 42 are mounted on the respective electrode support portions 41A and 42A. The electrode support portions 41A and 42A at the top positions of the electrodes 41 and 42 are not immersed in the treated water of the electrolytic cell 37. The electrode support portions 41A and 42A are supported by the support rods 37A and 37B described below. The structures shown in FIG. 3 are the electrodes 41 and 42 and the electrode support portions 41A and 42A. In addition, the one shown in Fig. 4 is a combined view of the electrodes 41 and 42 and the electrode support portions 41A and 42A mounted above the electrolytic cell 37. Referring to Figs. 3 and 4, the electrodes 41 and 42 are fixed to the tops of the electrode support portions 41 A and 42A by bolts. An appropriate surface of the electrode supporting portion 41A and the electrode supporting portion 42A is provided with a gasket 405 thereon. Then, the electrode supporting portions 41A and 42A shown in FIG. 4 are combined and fixed to each other through the spacer 405. The spacer 405 is appropriately adjusted, so that the distance between the electrodes 41 and 42 can be appropriately adjusted. Here, the configuration of the electrode support portions 41A and 42A will be described. Fig. 5 is a narrative view of the electrode supporting portion 41A. The electrode support 4 1 A includes wirings connected to the power supply device 38 and the electrode 41. One end of the wiring is a connector 410, and the other end is a connector 411. Since the electrode 41 is bolted to the electrode support portion 41A, it is electrically connected to the connector 410. The connector 411 is electrically connected to the power supply device 38. Therefore, the electrode 41 fixed to the electrode supporting portion 41A with a bolt is electrically connected to the power source device 38. In addition, the electrode support portion 42A is the same as the electrode support portion 41A, and has two connectors and includes wiring therein. Therefore, the electrode 41 and the power supply device 38 on the supporting portion 41A are electrically connected to each other by bolts fixed to the electrode support -21 · 1229657 V. Description of the invention (20). In order for the electrodes 41 and 42 and the electrode support portions 41A and 42A to have such a structure, the wiring between the electrodes 41 and 42 and the power supply device 38 should be avoided from crossing the treated water of the sewage treatment system of this embodiment. In addition, connectors with such splices should be protected from corrosion by being immersed in treated water. FIG. 6 is a narrative view of the electrolytic cell 37. Two support rods 37A and 37B above the electrolytic cell 37 are provided at predetermined intervals. Below the electrode support portions 41 A and 42A, they are arranged above the support rods 37A and 37B provided on the electrolytic cell 37. In short, the electrodes 41 and 42 are between the respective support rods 37A and 37B. In order to prevent the positions of the electrodes 41 and 42 from being generated in the electrolytic cell 37, an electrode support portion is provided to support the electrode 41 and 42 and has a cutout portion. As shown in Fig. 7, the electrode support portions are provided to support the electrodes 41 and 42 and are provided with cutout portions. On the front and back surfaces of the electrode support portion 450, cutout recesses 451 are formed which are embedded above the respective electrodes 41 and 42. The electrodes 41 and 42 on each cutout 451 are embedded above the electrodes 41 and 42 and fixed with bolts. Therefore, the positions of the electrodes 41 and 42 in the electrolytic cell 37 can be more reliably fixed, and the iron ion distribution in the electrolytic cell 37 is also stabilized. Therefore, the reaction of the formula (4) reacts stably in the electrolytic cell 37. Therefore, the sewage treatment device of the specific embodiment has a stable sewage treatment capacity. Moreover, when the electrode supporting part 450 is arranged above the electrolytic cell 37, the right end • 22-1229657 V. Description of the invention (21) 450A and the left end 450B are in contact with the supporting rods 37A and 37B. Then, the electrodes 41 and 42 are placed in the electrolytic cell 37 and are separated by the support rods 37A and 37B. When the electrode support portion 450 and the electrodes 41 and 42 are transported in a unit, as shown in FIG. 8, they are preferably stored in a box case for transport. In detail, the unitized electrode supporting portion 450 and the electrodes 41 and 42 mean that a part of the electrodes 41 and 42 is collected in the box cover 460 and stored in the box cover 460. Therefore, at the time of storage, the right end 450A of the electrode supporting portion 450 and the left end 450B of the electrode supporting portion 450 are fixed to the case with bolts 461 and 462, respectively.

Description of the invention (28) The outflow pipe 76 in the sedimentation tank 67 is provided with a magnet 67A. Therefore, aggregates of phosphorus compounds generated in the ion supply tank 70 and other aggregates separated from the sludge can be efficiently adsorbed by the magnets 67. In this way, in the sewage treatment device used in this embodiment, the embodiment 4 can be sent and recovered with higher efficiency. [Specific embodiment 6] Referring to FIG. 15, the entire structure of the sewage treatment device in this embodiment is the same as the structure of the sewage treatment device shown in FIG. 13, and is the same as the constituent elements of the sewage treatment device shown in FIG. 13. If it is the same, it will be indicated by the same reference number and will not be repeated. The sewage treatment device of this embodiment is divided into an activated sludge tank 1 0 1 area, an electrode 1 1 1 and 1 1 2 between partition walls 10 07 and 150 for receiving activated sludge flowing in from an inlet 109.

Explanation of the invention (29) The treated water discharged to the outside of the activated sludge tank is preferably sent to a separate anaerobic filter bed tank (a tank for anaerobic microorganisms). As for the activated sludge tank 101 containing the sludge 108 sedimentation area, in order to send the sludge 108 to the activated sludge storage area, its side wall is inclined. [Specific embodiment 7] This tool. The sewage treatment device of this embodiment is a sewage treatment device having a form in which manholes and electrodes are integrated. The sewage treatment device of this specific embodiment shown in FIG. 16 is compared with the sewage treatment device shown in FIG. 1 in that the structure of the manhole 28 and the surrounding parts of the electrodes 41 and 42 is changed. The components of the sewage treatment device shown in the figure are the same, they are indicated by the same reference number, and will not be repeated. Referring to Fig. 16, the upper part of the sewage treatment device is covered with a plurality of individual holes 28. The manhole 28 is provided with electrodes 41 and 42 passing through an insulator 400. Here, the mounting state of the insulators 400 of the electrodes 41 and 42 will be described with reference to FIG. 17. In the manhole 28 of the sewage treatment apparatus of this embodiment, electrodes 41 and 42 passing through the insulator 400 are installed. Specifically, the electrodes 41 and 42 are fixed to the insulator 400 by bolts or the like. Then, the insulators 400 to which the electrodes 41 and 42 are mounted are fixed to the manholes by bolts or the like. Then, various connectors 402 connected to the electrodes 41 and 42 are connected to the power supply device 38. Therefore, the operator can operate the manhole 28 with the handle 28A of the manhole 28 without going into the ground on the ground, and take out the electrodes 41 and 42 on the ground. Therefore, with regard to the electrodes 41 and 42-31 · 1229657 5. Maintenance of the invention (30), in terms of means, compared with other sewage treatment devices, the sewage treatment device of this embodiment is easier. The sewage treatment device of this embodiment is configured such that the electrodes 41 and 42 are immersed in the treated water, and the insulator 400 is not immersed in the treated water. In addition, both ends of the insulator 400 are provided with a connector capable of accommodating a connection line; one end of the connector is connected to the power supply device 38, and the other end of the connector is connected to the electrode 41 or 42. Therefore, the electrodes 41 and 42 and the continuous parts of the power supply device 38 can be prevented from being immersed in the treated water. Furthermore, it is possible to prevent the spliced portion from being corroded. In addition, in consideration of the positions of the electrodes 41 and 42 mounted on the manhole 28 and the electrodes 41 and 42 of the sewage treatment device, compared with the positions of the electrodes of other embodiments, this embodiment does not appear to be relatively high. Since the positions of the electrodes 41 and 42 are not located at 咼, the electrodes 41 and 42 are immersed in the treated water, and the electrodes 41 and 42 do not supply iron ions or aluminum ions when a voltage is applied. Therefore, 'this specific embodiment' is provided with a monitor that monitors the voltage between the electrodes 41 and 42 at the detection section 3 0 A to determine whether the electrodes 41 and 42 are immersed in the treated water. Therefore, 'the voltages of the electrodes 41 and 42 in the sewage treatment apparatus of this embodiment' indicate that the electrodes 41 and 42 are not immersed in the treated water, and it is more preferable to have an alarm device. [Embodiment 8] In the sewage treatment system shown in Fig. 18, the same symbol as that of the sewage treatment system (refer to Fig. 1) described in Embodiment 1 will not be repeated. Also, the "Figure 19" is a figure made by omitting the part shown in Figure 18 • 32-1229657 V. Description of the component of the invention (μ). Referring to FIG. 18 and FIG. 19, the sewage treatment system ′ of this embodiment is mainly composed of a tank 200. The interior of the tank 200 is composed of the first partition wall 2, the second partition wall 3, the third partition wall 4 and the fourth partition wall 20, the first anaerobic filter bed tank 5, and the second anaerobic filter bed tank 1. Areas drawn by aeration tank 14, sedimentation tank 19 and disinfection tank 21. Furthermore, when the tank 200 of this embodiment is designed to replace the third conveying pipe 29 and the first pump 18 shown in the tank 1 in FIG. 1, the bottom of the tank 200 is provided at the lower end of the third partition wall 4. isolation. Therefore, in the tank 200, the aerobic decomposition treatment water in the aeration aeration tank 14 is supplied to the sedimentation tank 19. The upper end of the first diffuser pipe 16 is connected to the first blower 17. Also, the lower end of the first diffuser 16, as described below. It is designed to contact one of the inner sides around the bottom of the aeration tank 14 (refer to Figure 19). A plurality of holes (holes 16a, see Fig. 19) are formed on the bottom surface side of the first diffuser pipe 16. Then, the air sent from the first blower 17 releases the air through the hole. In addition, due to the holes formed on the bottom surface side of the first air diffusing tube 16 and the holes formed on the upper or side surfaces thereof, it is difficult for the sludge to enter the inside. A pump 133 is provided at the bottom of the contact aeration tank 14. Furthermore, the top of the pump 133 is connected to the sludge return pipe 134, and the top of the sludge return pipe 134 extending to the left side of the figure is connected to the sludge return pipe 135. Thus, the sludge produced by the 'contact aeration tank 14' is sent to the first anaerobic filter bed tank 5. The sedimentation tank 19 and the first anaerobic filter bed tank 5 in the tank 200 of FIG. 18 are connected to the first anaerobic filter bed tank 5 -33-1229657 5. The description of the invention (32) is connected through the first return pipe 24. A second diffuser 25 is provided inside the first return pipe 24. The second air diffusing pipe 25 is connected to the second blower 26 and forms a spray hole for the purpose of spraying the air. Then, the air supplied by the second blower 26 is ejected from the ejection hole formed in the second air diffusing pipe 25, and the treated water in the sedimentation tank 19 is sent to the first anaerobic filter bed tank through the return pipe 24. Also, on the top of the contact aeration tank 14, a case 54 including an electrolytic unit is attached. Specifically, the box cover 54 is a hollow body formed by joining four vertical plates. In the inside of the case 54, electrode pairs 51 and 52 are provided. Each electrode pair 51 and 52 is connected to a power source 57. Furthermore, a third air diffusing tube 53 is provided inside the box cover 54. The third air diffuser 53 is connected to the fourth blower 56. The electrode pairs 5 1 and 52 that perform an electrolysis reaction (appropriately referred to as electrolysis) in the case 54 are metal ions such as iron ions or aluminum ions. Therefore, in the contact aeration tank 14, the dissolved metal ions react with the phosphorus compounds in the treated water to form water-insoluble metal salts and are aggregated. An example of the reaction between a metal ion and a phosphorus compound is represented by the formula (4) shown above. Next, the configuration of the electrolytic unit in this embodiment will be described with reference to Figs. 20 and 21. Figure 20 is a perspective view of an electrolytic cell. Fig. 21 is an exploded perspective view of the electrolytic cell. Four fixed positions at the upper end of the box cover 54 are provided for mounting components 541, 5 42, 5, 43 and 5 44. In addition, the box cover 54 is partitioned into two left and right spaces by partition walls 5 40 inside. Therefore, the third air diffusing tube 53 is introduced from above the box cover 34-1229657 V. Description of Invention (33) 54. The third air diffuser 53 extends' from the right to the left at the bottom of the case. The electrode pairs 51 and 52 are provided with two opposite electrodes 511, 512, 521, and 522. Then, the top ends of the two opposite electrodes of the electrode pairs 51 and 52 are mounted on the electrode supports 510 and 520. In addition, each of the electrode pairs 51 and 52 is connected to a power supply 5 7 (see FIG. 18) through connectors 513 and 523. The two ends of the electrode supporting bodies 510 and 520 are respectively installed by the mounting components 541, 5 42, 5, 43 and 544; the electrodes 511 and 512 are provided on the right side of the partition wall plate 540, and the electrodes 521 and 522 are provided on the To the left of the partition wall 540. The electrolytic reaction between the electrodes 511 and 512 is performed on the right side of the partition wall plate 540. The electrolytic reaction between the electrodes 521 and 522 is performed on the left side of the partition wall plate 540. In addition, the air bubbles released from the third air diffusing tube 53 hit the inner wall of the case 54 to generate convection in the case 54. Therefore, the treated water can be efficiently supplied in the vicinity of the electrodes 511, 512, 521, and 522. According to the third air diffusing pipe 53, a stirring means for achieving the stirring purpose in the space surrounded by the box cover according to the present embodiment is formed. In addition, since the air release device in the third air diffusing pipe 53 is limited, it is more suitable for mixing the water in the case 54 with a stirrer and other devices in terms of stirring means. In addition, the above-mentioned electrolytic reaction dissolves metal ions and reacts with phosphorus compounds in the treated water, thereby forming water-insoluble metal salts. In one aspect, the box cover 54 is a hollow body as described above. In addition, the box cover 54 is bottomless -35-1229657 V. The shape of the invention description (34). However, the metal salts generated here are acceleratedly introduced into the contact aeration tank 14 due to their own weight. The electrolysis unit of this embodiment described above is designed with a contact aeration tank 14. Furthermore, the electrolytic unit is preferably designed in the other anaerobic filter bed tank 5, the first anaerobic filter bed tank 10, or the sedimentation tank 19 in the tank 200. The sedimentation tank 19 of this embodiment is a sedimentation tank constituting sedimentation sludge. Furthermore, the electrolytic unit should be designed with an inlet 6 or a drain 23 adjacent to the outside of the tank 200. In addition, the return flow of the tank 200 is 3Q. The Q refers to the amount of water flowing into the tank 200. Accordingly, the tank 200 is circulated with a water amount three times the amount of the inflow water. In addition, the concentration of iron ions or aluminum ions eluted from the electrode pairs 51 and 52 in the electrolytic reaction was performed by treating the water with a concentration of 1 to 3 times the molted concentration of phosphorus. In addition, the concentration of iron ions or aluminum ions in the above-mentioned electrolytic reaction is preferably controlled to be 1 to 2 times the molted concentration of phosphorus in the treated water, and more preferably 1 5 times. Therefore, the current density applied to the electrolytic reaction electrode should be controlled at 0. 1 milliamp / cm 2 or more, and in most cases, it should be controlled at 0. 3 mA / cm² or more. Therefore, for the purpose of controlling the current density on the electrode, the formation of oxide films or organic deposits on the electrode surface should be prevented; and the removal of such oxide films or organic deposits should be considered. The water iron oxide or organic deposits generated on the anode side of the electrode should be taken into account because it will occur in -36-1229657 V. Description of the invention (35) Hydrogen on the cathode side or due to the third diffuser 53 aeration place Remove. However, when the above-mentioned electrolytic reaction is performed at a low current density, the amount of hydrogen generated on the cathode side is sufficiently low, and it is not possible to consider that the deposits formed on the anode side of the electrode will be removed. The aeration amount of the third diffuser pipe 53 used in the electrolytic unit is about 15 liters / minute. For example, if the daily flow rate of domestic sewage into the tank 200 is 1,200 liters and the circulating flow rate between the tanks in the tank 200 is 6000 liters, the current flowing between the electrodes 511 and 512 and the electrodes 521 and 522 is controlled at 650 milliamperes. The current density applied to each electrode is controlled by the change in the water immersion area of each electrode. In addition, the interval between the electrodes 511 and 512 and the interval between the electrodes 521 and 522 are usually about 25 mm, and the voltage between the electrodes is constantly monitored. Moreover, it is better to reverse the polarity of each electrode according to a predetermined time (for example, 24 hours). [Embodiment 9] The sewage treatment system shown in FIG. 22 is obtained by changing the configuration of the electrolytic unit and adding several of the constituent elements from the sewage treatment system shown in FIG. However, in FIG. 22, the same constituent elements as those in FIG. 18 are given the same symbols and will not be described repeatedly. Referring to Fig. 22, above the first anaerobic filter bed tank 5, an electrolysis unit including electrode pairs 51 and 52 is provided. Further, a third transfer pipe 38 and a pump 39 are provided in the sedimentation tank 19. The treated water in the contact aeration tank 14 flows into the sedimentation tank 19 through the third conveying pipe 38. Furthermore, this flow is facilitated by the pump 38. -37- 1229657 V. Description of the invention (36) The electrode pairs 51 and 5 2 are arranged in the electrolytic cell 5 9. The electrolytic cell 59 is connected to the first return pipe 24. Therefore, the treated water in the precipitation tank 19 is introduced into the electrolytic tank 59 through the first return pipe 24. In the upper left part of the electrolytic cell 59, a discharge pipe 592 is provided. The clear liquid above the treated water introduced into the electrolytic tank 59 flows through the discharge pipe 592 to the first anaerobic filter bed tank 5. A discharge port 591 is provided at the bottom of the electrolytic cell 59. Furthermore, a phosphorus recovery unit is provided in the first anaerobic filter bed tank 5, which is located below the electrolytic tank 5 9 and is adjacent to the electrolytic tank 59. As explained in the specific embodiment 8, the internal electrode pairs 5 1 and 5 2 of the electrolytic cell 5 9 undergo electrolytic reaction to generate metal ions, and the metal ions react with the treated water to become insoluble metal salts. The poorly soluble metal salts are introduced into the phosphorus recovery unit 160 through the discharge port 5 91 because of their own weight. Then, the poorly soluble gold salts are selectively recovered by the phosphorus recovery unit 160. FIG. 23 is a cross-sectional view of the phosphorus recovery unit 160. The phosphorus recovery unit 160 includes a body 164, nets 162 and 163, and an adsorbent 165. The adsorption material 165 is used to adsorb the finer ones of the above-mentioned insoluble metal salts, and is arranged between the nets 162 and 163, and is composed of activated carbon or ceramic magnets. The treated water and metal salts in the electrolytic cell 59 are introduced into the main body 164 through the nets 162 and 163. The clear liquid on the main body 164 is discharged into the first anaerobic filter bed tank 5 through a conveying pipe 16 1 outside the main body 164. Based on the above, the phosphorus recovery unit 160 of this embodiment is designed on the downstream side opposite to the electrolytic unit and is adjacent to the electrolytic unit. Therefore, -38- 1229657 V. Description of the Invention (37), the insoluble metal salts generated in the electrolytic cell 59 are concentrated on the bottom of the phosphorus recovery unit 160 body 164 and are adsorbed by the adsorbent 165. In short, the insoluble metal salts of the sewage treatment system of this embodiment are recovered without being mixed with the sludge. In addition, the presence of the adsorbent 1 65 allows finely insoluble metal salts to be recovered and also improves the recovery efficiency of the metal salts. The electrolytic unit and the phosphorus recovery unit 160 of this embodiment are designed in the first anaerobic filter bed tank 5. In addition, the electrolytic tank system is preferably designed as a second anaerobic filter bed tank 10 in the tank 1, a contact aeration tank 14 or a tank other than the sedimentation tank. However, in the case where the electrolytic unit and the phosphorus recovery unit 160 of this embodiment are designed in the first anaerobic filter bed tank 5 having a co-fouling removal tank, the phosphorus recovery unit 160 plays a very significant role. effect. In the case where the first anaerobic filter bed tank 5 without the electrolytic unit and the phosphorus recovery unit 160 is designed, 'although the electrolytic unit is set to other tanks with the same conditions', a single product of insoluble metal salts should be expected. The recovery system is difficult. [Example 10] First, referring to FIG. 24, the domestic sewage is first introduced into the sedimentation separation tank 601. In the precipitation separation tank 601, anaerobic decomposition of sewage is mainly performed. The sewage in the sedimentation separation tank 601 is introduced into the rotary contact tank 602. The rotary contact tank 602 mainly performs aerobic decomposition of sewage. In addition, in the return contact groove 602 ', a rotary filter bed for the growth of aerobic microorganisms is used. -39- 1229657 V. Description of the invention (38) The sewage in the rotary contact tank 602 is introduced into the sedimentation tank 603. The sedimentation tank 603 is designed to separate the sludge and liquid included in the sewage. The sludge settled in the sedimentation tank 603 is transferred to the sedimentation separation tank 601 by a known method. The sewage in the sedimentation tank 603 is introduced into the intermediate flow adjustment tank 604. The intermediate flow adjustment tank 604 is designed to adjust the flow rate of the sewage introduced into the electrolytic tank 605 described later. The sewage in the intermediate flow adjustment tank 604 is introduced into the electrolytic tank 605. The electrolytic cell 605 is a tank for the electrical decomposition of a predetermined component in the sewage and a reactive metal ion generating electrode. The detailed structure of the electrolytic cell 605 is described below. The sewage in the electrolytic tank 605 is introduced into the agglutination tank 606. The agglutination tank 606 is mainly used in the electrolytic cell 605. The metal ions produced are designed to react with predetermined components in sewage to form rubber plumes. In short, in the agglutination tank 606, metal ions react with predetermined components in the sewage. For example, in the case of an electrolytic reaction in which iron ions are eluted, it is expected that the iron ion is produced by a reaction following the above formula (4). Furthermore, the sewage in the agglutination tank 606 is introduced into the agglutination and sedimentation tank 607 together with the rubber plume generated as a result of the above reaction. The agglutination and sedimentation tank 607 is designed to settle the rubber plume generated in the agglutination tank 606. The sewage in the agglutination and sedimentation tank 607 is introduced into the disinfection tank 608. Disinfection tank 608 is equipped with chlorine and other drugs. The medicine in the disinfection tank 608 is designed to disinfect sewage. Therefore, the sewage in the disinfection tank 608 is discharged to rivers and the like. In addition, although there is phosphorus, phosphoric acid or -40-1229657 in the sewage. V. Description of the invention (39) Organic phosphorus, the total phosphorus concentration of the sewage discharged from the disinfection tank 608 is 1 mg / L. The processing method shown in FIG. 24B is designed to replace the electrolytic tank 605 and the agglutination tank 606 ′ shown in FIG. 24A with an agglutination tank 615, and metal ions are generated in the agglomeration tank 615. Predetermined components in the sewage react and form rubber plumes. In Figs. 24A and 24B, the sink separation tank 601, the turning contact tank 602, and the sedimentation tank 603 are surrounded by a dotted line R. The range surrounded by the dotted line R is not processed, and it is more suitable to change it as shown in FIG. Referring to Fig. 25, the sewage system in the sedimentation separation tank 601 is introduced into the contact aeration tank 620. The contact aeration tank 620 mainly causes aerobic bacteria to cause aerobic decomposition of sewage. In addition, the contact aeration tank 620 is different from the rotary contact tank 602 (refer to FIGS. 24A and 24B), and the hi-air filter bed does not rotate. The sewage in contact with the aeration tank 620 is introduced into the sedimentation tank 603. In addition, in the contact aeration tank 620, the sludge or biofilm attached to the aerobic filter bed which was peeled off due to aeration was transferred to the sedimentation separation tank 601 and the sedimentation tank 603 by a known method. Hereinbelow, a specific embodiment 10 of the present invention will be shown using a device for the purpose of the processing method shown in the flowchart shown in FIG. 24A. In addition, a device for performing the processing method shown in the flowchart shown in FIG. 24B is used to display the specific embodiment 11 of the present invention, as described below.

Powered. Electrolytic cell of pole pair 651. 605, will provide metal ions as described above. The metal ions supplied to the electrolytic cell 605 are sent to the aggregation tank 606 together with the sewage. The metal ions generated in the electrolytic cell 605 react in the agglutination tank 606 with the sewage. In the agglutination tank 606, metal ions react with sewage to form rubber plumes such as phosphorus metal salts. This rubber plume and sewage are sent to the agglutination and sedimentation tank 607, and settle in the agglutination and sedimentation tank 607. The specific embodiment described above has a structure in which the sewage after the nitrogen removal treatment in the agglutination tank 606 reacts with metal ions and has a first tank 60 for agglutination of the precipitate generated by the reaction. In addition, the agglutination and sedimentation tank 607 includes a second tank for the sewage introduced from the first tank and the first tank for agglomerates to settle. In short, the electrolytic cell 605 is composed of an electrolytic cell that supplies metal ions to the first cell due to the solution of the electrodes. In the specific embodiment described above, the metal ions that react with the sewage are supplied by the electrolytic reaction of the electrodes. Therefore, compared with the case where metal ions are supplied by adding a coagulant to the sewage, the metal ions supplied according to the present invention have the advantage of safety. Agglutinating agents, pH adjusting agents added for agglutination, and acidic or alkaline agents can cause danger. Furthermore, compared with the case where agglutinating agents are added to sewage, it is not necessary to adjust the pH of sewage, and the sewage is easy. The ground reacts with metal ions, which is also an advantage of the present invention. Moreover, compared with the case where the coagulant is added to the sewage, there is no need to store the coagulant, which is also an advantage of the present invention. In addition, the electrode pair undergoes an electrolytic reaction, and the concentration of the dissolved iron or aluminum ions is the volume of phosphorus in the treated water. Mole concentration is 1 to 4 times. Also, the concentration of iron ions or aluminum ions in the above-mentioned electrolytic reaction, it is desirable to control the volumetric molar concentration of phosphorus in the treated water by 2. 5 ~ 3. 5 times, more preferably controlled at 3. 0 degree. To achieve this later, the current density of the electrode electrolysis reaction should be controlled at 0. Above 1 milliamp / cm2, in most cases, it will be controlled at 0. 3 milliamps per square centimeter. Therefore, since the current density of the electrode is controlled, it is expected that an oxide film or an organic deposit on the electrode surface can be prevented and removed. The predictable water oxide film or organic deposits generated on the anode side of the electrode will be predicted to be due to the hydrogen generated on the cathode side of the electrode -47-1229657 V. Description of the invention (46), Or it is removed by aeration of the air diffuser 654. However, in the case where the current density of the above-mentioned electrolytic reaction is low, the amount of hydrogen generated on the cathode side of the electrode is low, and it is expected that the attached matter generated on the anode side cannot be removed. In the electrolytic unit, the aeration amount of the air diffuser 654 was 15 liters / minute. For example, in the case of an aggregate sedimentation device including a combined purification tank, where the daily flow of domestic sewage is 10 tons, the current flowing between the electrodes 7 1 1 and 7 1 2 is controlled to 1 2 · 3 amps. Therefore, in the electrolytic reaction of the electrode pair 6 51, the concentration of iron ions or aluminum ions produced can be expected to be 3. The molar concentration of phosphorus in the treated water is 3. 0 times. The current density applied to each electrode is controlled by the change in the water immersion area of each electrode. In addition, the distance between the electrodes 711 and 712 in each electrode pair 651 is usually about 25 mm, and the voltage between the electrodes is constantly monitored. Moreover, it is better to reverse the polarity of each electrode at a predetermined time (for example, 24 hours). The residence time of sewage in the agglomeration tank 606 is usually more than 20 minutes. The residence time of the sewage in the agglomeration and sedimentation tank 607 is usually more than 3 hours. Therefore, in this specific embodiment, the residence time of the sewage in the aggregation tank 605 is preferably more than 3 minutes. The conditions for these dwell times are based on the results of the test on the dwell time of the electrolytic cell. The above tests are explained below. [Determination test of electrolytic cell residence time] -48- 1229657 V. Description of the invention (47) Π Test method: Without artificial aeration, make the artificial preparation liquid undergo the electrical decomposition of iron at a predetermined time. Device (refer to Figure 32) to obtain the phosphorus removal rate of this artificially prepared solution at various depths. The artificial preparation liquid is the artificial preparation liquid which has the same composition as the sewage usually introduced into the agglutination tank 615 'through artificial preparation. Artificial gas distribution: The composition of the liquid is shown in Table 1. Also, the electrolysis of iron in the artificial preparation of this test uses 3 liters and 4 liters of electrolytic cells, and each electrolytic cell uses 3. Aeration of 5 liters / minute. This electrical decomposition controls the amount of iron in the artificially prepared liquid because it controls the amount of current flowing through the electrode. For example, in order to make the molar number of iron ions in the artificial preparation solution to be about 2 of the molar number of phosphorus mols. 5 times and about 3.0 times, the amount of current flowing through the electrodes in each electrolytic cell is 1 · 30 amps and 1.5 5 amps. Referring to Fig. 32, the sedimentation measuring device 700 has a cylindrical shape, and is mainly composed of a containing portion 790 for containing a solution. In addition, on the side of the storage portion 790, there are provided solution extraction portions 791 to 796 that can extract a solution existing in various depths of the storage portion 790. The solution extraction parts 791, 792, 79 3, 794, 795, and 796 can be extracted from the water surface to 0. 3 meters, 0. 5 meters, 0. 7 meters, 0. 9 meters, 1. 1 meter and 1. 3 meter deep solution. 2) Test results In the electrolytic cell 37 shown in Fig. 33, after conducting electrolysis of iron for 3 minutes, -49-1229657 V. Description of the invention (48) The artificially prepared liquid of the electrolytic cell was transferred to a sedimentation tester to make it Perform quick stir (with 150i. Stir with pm for 10 minutes) and slow stirring (stir with 60 rPm for 10 minutes), and measure the phosphorus removal rate at various depths of the sedimentation tester 700. In addition, in this 3 minute electrolysis, the amount of current applied to the electrodes is controlled so that the molar number of iron ions dissolved out is about 2 in the number of phosphorus molars in the artificially prepared solution. 5 times. Figure 33 shows the agglomerates in the sedimentation tester 700, and the sedimentation time is 1. Phosphorus removal rate at 5 hours. Therefore, in Figure 3 3, ▲ and the national system respectively indicate that the agglomerate sedimentation time is 3. 0 hours, 4. Phosphorus removal rate at 0 hours. In addition, in the following Figures 33 to 36, ❿, ▲, and the system respectively indicate that the agglomerate sedimentation time is 1. 5 hours, 3. 0. Hours and 4 · 0 hours of phosphorus removal rate. Phosphorus removal rate Rp refers to the initial concentration of phosphorus in the artificial preparation solution is Cs' After a period of sedimentation time, when the phosphorus concentration in the artificial preparation solution at various depths is Cd, it is calculated by the following formula (5) Come out. Rp two {(Cs-Cd) Cs} X100 · ·. (5) Also ‘determined the depth of phosphorus removal rate in FIG. 33, which is the distance between the solution extraction portion 791 ~ 796 and the water surface 0. Extraction depths from 5 meters deep (indicated by P in Figure 32). Referring to Figure 33, the shallower the phosphorus removal rate, the more gradually it increases. Furthermore, when the agglomerate h 几 decline time is more than 3.0 hours, the phosphorus removal rate at this depth is 60%, or an approximate 値 of the 値. In addition, in a general combined purification tank, the time for the agglomeration tank to diffuse is -50-1229657 V. Description of the invention (49) is 20 minutes, and the sedimentation time of the agglomeration sedimentation tank is at least 3 hours. Therefore, in this test, the electrolysis time required to dissolve the same amount of iron ions is shorter than 3 minutes, and when the sedimentation time in the sedimentation measuring device 700 is more than 3 hours, at each depth The removal rate of phosphorus is lower than that shown in Fig. 33. Moreover, when the above electrolysis is performed for longer than 3 minutes, the removal rate of phosphorus at each depth is relatively much larger than that shown in Fig. 33. Therefore, the electrolysis time, that is, the residence time of the sewage in the electrolytic tank 605 of this embodiment, is expected to be more than 3 minutes. (1) The review of the agitation in the agglutination tank is shown in Figure 34. The indicator is based on the test conditions based on the results obtained in Figure 33, but when the agitation (fast agitation and slow agitation) of the sedimentation tester 700 is omitted, the phosphorus removal rates at various depths are measured. Referring to Figure 34, stirring is omitted and the settling time is 4. In the case of 0 hours, the removal rate of phosphorus in the upper liquid is approximately 60%; otherwise, the removal rate of phosphorus is about 40%. Furthermore, the settling time is 3. In the case of 0 hours, the removal rate of phosphorus in the clear liquid above about 5 meters deep is about 40%; in other cases, the removal rate of phosphorus is about 35%. Moreover, when the settling time is 1.5 hours, the result obtained is: the removal rate of the spleen in the upper liquid is about 40%; 0. The depth of 3 meters to 0.7 meters is about 20%; 0.9 meters to 1. The depth of 1 meter is about 15%; phosphorus is not removed at a depth of 1.3 meters. -51-1229657 V. Description of the invention (50) In summary, comparing the result shown in FIG. 33 with the result shown in FIG. 34, the removal rate of phosphorus becomes less when the sedimentation measuring device 700 is not stirred. More low. For this reason, the apparatus for forming phosphorus metal salts or SS rubber feathers, that is, the agglutination tank 606 of the present embodiment, can be expected to reliably remove phosphorus from sewage due to stirring. 1) The review of the relationship between the molar number of phosphorus in sewage and the molar number of iron ions dissolved in electrolysis is shown in Figures 35 and 36, which is based on the test conditions based on the results obtained in Figures 33 and 34 However, the molar number of iron ions dissolved in the electrolytic cell is 2 from the phosphorus molar number in the sewage. 5 times change to 3. In the case of 0 times, the removal rate of phosphorus was measured at various depths. In a word, the result shown in FIG. 35 is the result measured when the sedimentation measuring device 700 has stirring (fast stirring and slow stirring); and the result shown in FIG. 35 is the sedimentation measurement. Measured with the device 700 without stirring. Referring to Fig. 35 and Fig. 36, according to the stirring method for manually preparing the liquid in the sedimentation measuring device 700, in all cases where there is stirring, it has a partial removal rate of phosphorus. However, regarding the presence or absence of stirring of the sedimentation measuring device 700, when the sedimentation time is more than 3 hours, the removal rate of phosphorus in the upper liquid is about 80%; otherwise, the removal rate is about About 70%. Therefore, when the electrode is electrolyzed, the molar number of iron ions is 3. When it is 0 times, it can be expected and it is related to the presence or absence of agitation in the agglomeration tank. -52-1229657 V. Description of the invention (51), the phosphorus removal rate reaches 70 ~ 80% high efficiency.
