汙水處理的主要目的在於避免放流水汙染及汙泥減量。現今的各個汙水處理廠可採用許多不同的汙水處理方法及裝置。習用的汙水處理裝置大致包含有前處理結構、初步沉澱池、二次沉澱池、好氧生物處理結構、厭氧生物消化結構等。可使最終產生的處理水符合放流標準或方便回收再利用。另外,還可降低汙泥固體的量,節省後續處理成本。再者,還可產生甲烷,增加經濟效益。 The main purpose of sewage treatment is to avoid discharge water pollution and sludge reduction. Many different sewage treatment methods and devices can be used in various sewage treatment plants today. Conventional sewage treatment equipment generally includes pre-treatment structure, preliminary sedimentation tank, secondary sedimentation tank, aerobic biological treatment structure, anaerobic biological digestion structure, etc. It can make the finally produced treated water meet the discharge standard or facilitate recycling and reuse. In addition, it can also reduce the amount of sludge solids and save subsequent treatment costs. Furthermore, it can also produce methane, increasing economic benefits.

然而,習用的汙水處理方法及裝置還具有下列缺失:1.例如粗格柵、細格柵等結構的功能不足,難以篩除例如毛髮及綿絮等懸浮物,造成後續處理程序操作問題,例如影響馬達、管線及薄膜單元;2.初步沉澱池及二次沉澱池的固液分離效果差且效率也差,故需要設置很大面積的初步沉澱池及二次沉澱池,造成占地大、成本高等問題;3.初步沉澱池及 二次沉澱池的固液分離效果差,例如未能將懸浮物及油脂等雜物有效移除,影響後續操作,尤其嚴重影響厭氧消化結構的處理效率及甲烷產量;4.初步沉澱池及二次沉澱池的固液分離效率差,需要花費很長的時間。 However, conventional sewage treatment methods and devices also have the following deficiencies: 1. The functions of structures such as coarse grids and fine grids are insufficient, and it is difficult to screen out suspended solids such as hair and floss, which causes operation problems in subsequent treatment procedures. For example, it affects motors, pipelines and membrane units; 2. The solid-liquid separation effect of the preliminary sedimentation tank and the secondary sedimentation tank is poor and the efficiency is also poor, so a large area of the preliminary sedimentation tank and the secondary sedimentation tank need to be set up, resulting in a large area , High cost and other issues; 3. Preliminary sedimentation tank and The solid-liquid separation effect of the secondary sedimentation tank is poor, such as the failure to effectively remove the suspended solids and grease and other impurities, which affects the subsequent operations, especially the treatment efficiency of the anaerobic digestion structure and the methane output; 4. The preliminary sedimentation tank and The solid-liquid separation efficiency of the secondary sedimentation tank is poor and it takes a long time.

步驟a1)為以前處理結構1處理汙水,產生第一處理水。前處理結構1連接一汙水源11,可處理汙水源的汙水以產生第一處理水。前處理結構1可以包含例如粗格柵、細格柵、渦流沉砂結構及/或曝氣沉砂結構等結構中之一或二者以上,主要用於過濾汙水中的大型雜物及較重砂礫,其為習用技術,故不再贅述。 Step a1) is the treatment of sewage by the previous treatment structure 1 to produce first treated water. The pre-treatment structure 1 is connected to a sewage source 11, and can treat sewage from the sewage source to produce first treated water. The pre-treatment structure 1 may include one or more of such structures as coarse grating, fine grating, vortex grit structure and/or aeration grit structure, and is mainly used to filter large debris and heavier sewage in sewage. Gravel is a conventional technique, so I won’t repeat it.

步驟a2)為以一第一微濾結構2過濾第一處理水,產生第二處理水及第一汙泥;第一微濾結構2含有一第一金屬編織濾網21及一第一循環反沖洗結構22。第一微濾結構2連接前處理結構1以接收第一處理水,其能以掃流式過濾處理第一處理水。 Step a2) is to filter the first treated water with a first microfiltration structure 2 to produce second treated water and first sludge; the first microfiltration structure 2 contains a first metal woven filter mesh 21 and a first circulating reactor Rinse structure 22. The first microfiltration structure 2 is connected to the pretreatment structure 1 to receive the first treated water, which can process the first treated water by swept-flow filtration.

第一循環反沖洗結構22可具有一第一反沖洗噴射結構221及一第一支撐結構222。第一反沖洗噴射結構221主要用於噴射例如氣體或液體等流體,可以採用流體噴射結構,例如具有許多朝向第一金屬編織濾網21之噴射孔2211的 管體,或是由一個以上的噴射頭所構成(圖中未示)。第一反沖洗噴射結構221的特點在於只反沖洗第一金屬編織濾網21的一部分結構,並可配合第一支撐結構222循環反沖洗第一金屬編織濾網21的大部分或全部結構(如圖4所示);藉此結構,可以在第一金屬編織濾網21過濾第一處理水時,一併進行反沖洗。 The first circulating backwash structure 22 may have a first backwash spray structure 221 and a first support structure 222. The first backwash injection structure 221 is mainly used to inject fluids such as gas or liquid. A fluid injection structure may be used, for example, there are many injection holes 2211 facing the first metal woven filter screen 21. The tube body may be composed of more than one spray head (not shown in the figure). The first backwash jet structure 221 is characterized by only backwashing a part of the first metal woven filter screen 21, and can cooperate with the first support structure 222 to cyclically backwash most or all of the first metal woven filter screen 21 (such as 4); With this structure, when the first metal woven filter 21 filters the first treated water, backwashing can be performed at the same time.

步驟a3)為以一好氧生物反應結構3處理第二處理水,產生第三處理水。好氧生物反應結構3連接第一微濾結構2以接收第二處理水,可利用好氧生物淨化水中的溶解性有機物,其為習用技術,故不再贅述。 Step a3) is to treat the second treated water with an aerobic biological reaction structure 3 to produce the third treated water. The aerobic biological reaction structure 3 is connected to the first microfiltration structure 2 to receive the second treated water, and the aerobic organisms can be used to purify the dissolved organic matter in the water. This is a conventional technology, so it will not be repeated.

步驟a4)為以一第二微濾結構4過濾第三處理水,產生第四處理水及第二汙泥。第二微濾結構4可以採用與第一微濾結構2大致相同的結構,其含有一第二金屬編織濾網41及一第二循環反沖洗結構42,且第二循環反沖洗結構42可具有至少一第二反沖洗噴射結構421及一第二支撐結構422等結構。第二微濾結構4連接好氧生物反應結構3以接收第三處理水,其能以掃流式過濾處理第三處理水,進而產生第四處理水。經過前述步驟產生的第四處理水已經可符合放流標準,必要時亦可在經過例如消毒等後處理以後再放流,另外亦可回收再利用。 Step a4) is to filter the third treated water with a second microfiltration structure 4 to produce fourth treated water and second sludge. The second microfiltration structure 4 may adopt a structure substantially the same as that of the first microfiltration structure 2, which includes a second metal woven filter screen 41 and a second circulating backwashing structure 42, and the second circulating backwashing structure 42 may have At least one second backwash jet structure 421 and one second support structure 422 are structures. The second microfiltration structure 4 is connected to the aerobic biological reaction structure 3 to receive the third treated water, which can process the third treated water by swept-flow filtration to produce the fourth treated water. The fourth treated water produced through the foregoing steps can already meet the discharge standard, and can also be discharged after post-treatment such as disinfection if necessary, and it can also be recycled and reused.

第一微濾結構2及第二微濾結構4的第一金屬編織濾網21及第二金屬編織濾網41均為微濾等級的薄膜,可以 因應例如不同汙水之狀況而選擇不同的目數及孔徑(圖中未示)。 The first woven metal filter mesh 21 and the second woven metal filter mesh 41 of the first microfiltration structure 2 and the second microfiltration structure 4 are both microfiltration grade membranes. Choose different meshes and apertures (not shown in the figure) in response to, for example, different sewage conditions.

如前所述,第二微濾結構4可以採用與第一微濾結構2大致相同的結構,其中的差異在於所需過慮的第一處理水及第三處理水的狀況不同,因此可選擇不同的目數及孔徑(圖中未示),例如採用目數可為400~500mesh(目數)且孔徑可為30~38μm(微米)的第一金屬編織濾網,及目數可為200~500mesh(目數)且孔徑可為25~75μm(微米)的第二金屬編織濾網(圖中未示)。 As mentioned above, the second microfiltration structure 4 can adopt approximately the same structure as the first microfiltration structure 2. The difference is that the conditions of the first and third treated water to be filtered are different, so you can choose different The mesh and pore size (not shown in the figure), for example, the first metal woven filter with a mesh size of 400~500mesh (mesh) and a pore size of 30~38μm (micrometer) can be used, and the mesh size can be 200~ A second metal woven filter screen (not shown in the figure) with 500 mesh (mesh) and a pore size of 25~75 μm (micrometers).

步驟a5)為以混合及濃縮結構5處理第一汙泥及第二汙泥,產生第三汙泥。混合及濃縮結構5連接第一微濾結構2及第二微濾結構4以接收第一汙泥及第二汙泥,可由一混合槽及一濃縮槽所組成(圖中未示),主要用於汙泥之混合及脫水,其為習用技術,故不再贅述。 Step a5) is to process the first sludge and the second sludge with the mixing and thickening structure 5 to produce the third sludge. The mixing and thickening structure 5 connects the first microfiltration structure 2 and the second microfiltration structure 4 to receive the first sludge and the second sludge. It can be composed of a mixing tank and a thickening tank (not shown in the figure), and is mainly used The mixing and dewatering of sludge is a conventional technique, so it will not be repeated here.

步驟a6)為以一厭氧生物消化結構6處理第三汙泥,產生甲烷及第四汙泥。厭氧生物消化結構6連接混合及濃縮結構5以接收第三汙泥,其應用於可生物降解的廢水中,可產生甲烷,其為習用技術,故不再贅述。 Step a6) is to treat the third sludge with an anaerobic biological digestion structure 6 to produce methane and the fourth sludge. The anaerobic biological digestion structure 6 is connected to the mixing and thickening structure 5 to receive the third sludge, which is used in biodegradable wastewater to produce methane, which is a conventional technology, so it will not be repeated.
