第1圖係爲本發明之第1實施例，在處理被覆型最終處 理場中滲出水之方法中，係實施以晶析法脫鹽之方法。 在一般廢棄物或事業廢棄物之最終處理場中，爲了使廢 棄物達成安定化及無害化之目的，因而對所被覆之廢棄物 進行灑水，但就被覆型即封閉系統之廢棄物最終處理場而 言，由於控制灑水量而使滲出水之濃度變高，例如，使滲 出水之氯離子濃度變爲2倍左右，乃進行脫鹽處理。又， 在滲出水中所含有的有機物量（BOD、COD等），係因廢棄物 之內容大小而左右，爲了放流脫鹽水，則有必要進行符合 放流標準之有機物去除處理。 在第1圖所示之本發明第1實施例中，係利用灑水裝置 (2)對被覆型最終處理場之廢棄物（1)灑水，並將所得到的 含高濃度鹽之滲出水（3 )予以脫鹽，首先除去來自滲出水 1243155 五、發明說明（5) 所含高濃度鹽中之Ca成分。也就是說，將，含高濃度鹽 之滲出水予以導入Ca成分去除水槽中，添加Na2C03及凝 集劑。因此，形成CaC03沉澱，同時凝集、沉澱一部分之 有機物，利用脫水機將該等沉澱物予以脫水，將因脫水而 分離之沉澱污泥排出到預定之外部處置場，將藉脫水之經 分離的水分，予以反送至Ca成分去除水槽之入口區，與 滲出水一起再處理。 另一方面，從Ca成分去除水槽排出的Ca成分去除之後 之中間處理水，係被導入晶析鹽固化裝置內。 又，在此處，利用灑水裝置（2 )對被覆型最終處理場之 廢棄物（1 )灑水所得到的含高濃度鹽之滲出水（3 )量爲「W 」之情況下，被導入除去Ca成分等之晶析鹽固化裝置內 的中間處理水量也是「W」，大槪相等之量。 從而，自廢棄物之滲出水中除去Ca成分，係可防止Ca 危害。也就是說，在滲出水中含有Ca成分時，由於附著 在傳熱管等之結垢量會變得較多，當利用Ca沉澱等前處 理將可使之減輕。在此種情況下，較宜是進行絕熱裝置之 檢查，或者必需要不只留意Ca成分之附著，而且須留意 矽結垢之附著。又，CaC03之沉澱速度雖然是快速，但由 於在槽底部容易使之沉澱固化，較宜是調整成連續地安定 排出。 將Ca成分去除之後之中間處理水予以導入晶析鹽固化 裝置’藉由晶析方法而使之脫鹽。此處，實施恰爲蒸發法 1243155 五、發明說明（6) 之晶析方法，係使用蒸氣噴嘴。所供給之蒸氣，係爲將工 業用水導入鍋爐中所產生之物，其量爲0.5W左右。又， 在此種情形下，必需要留意滲出水中之有機物及有害微量 物質之飛散，較宜是一方面藉由真空裝置來吸引，能夠僅 在低溫下操作更佳。在晶析裝置之罐底附近所排出之固態 鹽，係藉由脫水機使之脫水，將經脫水分離之固態鹽移出 ，不進行燒烤等加熱處理，將所得到的高純度鹽向外部移 出。 又，在晶析裝置中，由於使用噴射器可以使蒸氣量減半 ，因而能量較少所以較爲有利。又，晶析方法，因收集鹽 漿液，因而在連輸作業上多少必需要一籃技術。更且，在 晶析裝置之罐底，由於容易因固態鹽而發生阻塞，可以攪 拌等來防止之，同時藉由適當之配管等流速來防止阻塞。 又，較宜是使裝置之負荷或漿液濃度在適當之値，以一定 値來運轉之。 根據本發明，該自晶析裝置流出之脫鹽水爲1.5W中之 1 . 0W，係可以將之循環（意即循環再利用）來做爲處理場內 之灑水用水。 從而，爲使進行放流，0 . 5W之脫鹽水的殘留部分係以生 物處理來分解其所含的有機物，將生物污泥予以凝集沉澱 ，並進一步以砂過濾及活性碳處理後，再利用來做爲工業 用水之處理水，或者是予以放流。 又，將在凝集沉澱步驟中藉凝集而沉澱之沉澱物，上述 1243155 五、 發明說明（7) CaC032沉澱物送到脫水機中，在該處與CaC〇3之沉 澱 物 一 起 脫水。當處理水做爲工業用水而再利用之情況 ，( ).5W 之 處 理水係經鍋爐而變成蒸氣，並供給到上述晶析 裝 置 之 噴 射 器。或者，又於再利用做爲工業用水之情形下 ，( ).5W 之 處 理水係做爲冷卻塔之補充水。 從而，依照本發明第1實施例之處理在被覆型 最 終 處 理 場 中的滲出水之方法，將對所被覆一般廢棄物或 事 業 廢 棄 物 灑水而產生之含有高濃度鹽分之滲出水予以脫 鹽 並 將 經 脫鹽水在處理場內循環再利用，將可達成使被 覆 型 最 終 處 理場內無害化、安定化之效果。 又，處理來自被覆型最終處理場之一般廢棄物 或 事 業 廢 棄 物滲出水的設備，爲了處理高濃度鹽分等之滲 出水 在 達 行維護管理時，有必要同時小心結垢之附著、 阻 塞 、 腐 蝕 等，並注意不引起有機物及微量有害物質等之: 飛散 〇 例如，就防止腐蝕而言，可以使用極度真空之 低 溫 程 序 及 機器病防止腐蝕。在成爲意料外高溫的情形下 ’ 會 因 氯 離 子（c Γ )而形成點狀腐蝕，則可使用可對抗應 力 腐 蝕 侵 害 之鈦等材質。尤其，應注意傳熱管等之腐飩。 在 使 用 不 銹 鋼之情況下，應考慮電氣防蝕。 關於環境保護方面，爲使不發生有機物、重金 屬 、 戴 奧 辛 (以下，稱爲DXN)等之微量有害物質向環境飛 散 、

第2圖所示者係爲本發明第2實施例，其係處理來自在 被覆型最終處理場中一般廢棄物或事業廢棄物之滲出水的 方法，其中在生物處理後，係實施晶析法脫鹽之程序。 直接將被覆型最終處理場中之滲出水予以鹽固化設備來 處理時，有機物或微量有害物質係混入所生成鹽中，預料 得到將難以有效地利用或循環、或處置該生成鹽。因此之 故，則必需要對生成鹽予以加熱處理或燒烤處理。 此處，在第2圖所示之本發明第2實施例中，其係利用 灑水裝置（2 )對被覆型最終處理場之廢棄物（1 )灑水，並將 所得到的含高濃度鹽之滲出水（3 )予以脫鹽，與上述實施 例1之情況同樣地，首先是除去Ca成分。 因爲除去Ca成分後之中間處理水之鹽濃度係爲高的， 因而生物處理會受鹽傷害而不能達行，所以較宜是將以水 稀釋鹽濃度使成爲比海水淡之一定濃度的脫鹽水。因此， 在，除去Ca成分後之中間處理水W中加入2W之稀釋水， 將所得到之3W混合物水導入生物處理設備，以生物處理 分解所含之有機物，使生物污泥凝集沉澱，並進一步進行 砂過濾及活性碳處理。從而，將砂過濾及活性碳處理後之 處理水導入晶析鹽固化裝置內，藉由晶析方法予以脫鹽。 -10- 1243155 五、發明說明（9) 此處，實施恰爲蒸發法之晶析方法，係使用蒸氣噴嘴。所 供給之蒸氣，係爲將工業用水導入鍋爐中所產生之物，其 量爲1 .

依照本發明，該從晶析裝置中流出之4. 5W脫鹽水，其 中之1 · 0W係循環（意即循環再利用）做爲處理場內之灑水 用水，2.0W係循環再利用做爲生物處理之稀釋水，殘留部 分之0.5W係再利用來做爲工業用水之處理水，或者是予 以放流。 又，將在凝集沉澱步驟中藉凝集而沉澱之沉澱物，上述 CaC03之沉澱物送到脫水機中，在該處與CaC03之沉澱物一 起脫水。當1 .

此處，在第3圖所示之本發明第3實施例中，其係利用 灑水裝置（2)對被覆型最終處理場之廢棄物（1)灑水，並將 所得到的含高濃度鹽之滲出水（3 )予以脫鹽，與上述實施 例1之情況同樣地，首先是除去C a成分。 接著，將除去Ca成分後之中間處理水W，利用由鼓式乾 燥機所成之直接鹽固化設備來處理、予以脫鹽。 在鼓式乾燥機等直接乾燥設備中，由於需要注意處理水

Description of the invention (1 :) [Technical field to which the invention belongs] The present invention relates to-^ treatment methods for seepage water in the final treatment field of covered type (meaning closed system). It has always been used in general waste and business. In terms of waste treatment, in the non-covered type, the so-called open type treatment field, the chloride ion concentration of the exuded water is about 10,000 ppm due to the relationship of rainwater. Therefore, the exuded water can be biologically treated, for example, by activated sewage. The mud method is used to remove organic matter, and the treated water is discharged. On the other hand, in the coating type final treatment field, because the amount of water spray is less than that of rainwater, the concentration of oozing water is higher than that of seawater High salt concentration will cause salt damage to thick crops, which will not be released without desalination and used as a sprinkler in the treatment field. Under the salt cycle, the treatment site will become the so-called salt area; therefore, the J result will make the treatment site unable to achieve -fml III ΙΓ J \\\ The problem of damage and stabilization. [Background of the Invention] The present invention provides — * Species are the treatment methods of the seepage water in the coating type final treatment field that can solve the above problems. The seepage water is the water generated by the sprinkle of general waste and business waste. The coating type of the present invention is the final Treatment method 5 for seepage water in the treatment plant is characterized in that the seepage water containing high concentration of salt generated by watering the covered general waste or business waste is desalted by crystallization method or drying method J reuse the desalted water through I 4m as the sprinkler water in the treatment site. 0-3- 1243155 V. Description of the invention (2: Another, another invention is a A method for treating oozing water in a coating type final treatment field, which is characterized in that the method for treating the oozing water in a coating type final treatment field is to contain a high concentration of salt generated by spraying water on the covered general waste or business waste. The effluent water is firstly removed from the C a component, and then the crystallization method is used to desalinate the intermediate treated water from which the C a component is removed, and part of the desalinated water is recycled as the sprinkler water in the treatment plant. Water and biological treatment at the same time to decompose the organic matter contained in the residual part of the desalinated water, the biological sludge will be agglomerated and precipitated, and further filtered with sand cm and activated carbon treatment > reused as treated water for industrial water , Or be released. In addition, the other one is: Ming: This is a method for treating the seepage of the coating type final treatment field, which is characterized in that: The method of treating the seepage of the coating type final treatment field is due to the The effluent water containing high concentration of salt produced by watering the business waste, first remove the Ca component of it. The crystallization method will be used to decompose the organic matter contained in the demineralized residue by biological treatment to agglutinate and precipitate the biological sludge. ， Go forward— * Step by desalting the treated water after sand filtration and activated carbon treatment, and recycling a part of the desalinated water as the sprinkler water in the treatment site. The remaining part of the desalted water is reused. For the treatment of industrial water, water, or _ to release. In addition, the other one is a method of treating oozing water in the coating type final treatment field, which is characterized in that: The method of treating the oozing water in the coating type final treatment field is due to the Leaching water containing high-concentration salinity produced by spraying waste or business waste -4-, first remove the Ca component 1243155 V. Description of the invention (3), and then use a drum dryer to dry the The intermediate treatment water from which the Ca component is removed is desalinated, and a part of the desalted water is recycled as the sprinkler water in the treatment plant, and at the same time, the biological treatment is performed to decompose the organic matter contained in the demineralized residue, and Biological sludge is aggregated and precipitated, and further treated with sand filtration and activated carbon, and then reused as industrial water treatment water or discharged. According to the method of the present invention, the effect of detoxifying and stabilizing the coating type final treatment field can be achieved even in any of the above-mentioned occasions. In addition, the desalting of the effluent water containing a high concentration of salt from general waste or business waste is the crystallization method described above by an evaporation method, or by using, for example, a drum dryer, a disc, or the like. Direct drying methods such as air dryers, turbulent heat exchangers, and spray dryers; among them, the crystallization method can use an ejector to halve the amount of steam, so it is more advantageous and better in terms of energy and drying The method is preferably a drum dryer. In addition, when the salt concentration of the exuding water is light and the amount of water is large, it is preferable to install an energy-saving evaporation concentration method, a RO concentration method, or an electrodialysis method before introducing the salt curing device. Furthermore, in the leaching water from general waste or business waste in the treatment-type final treatment plant, there is no need to worry about the leakage and outflow of trace harmful substances (especially dioxin or environmental hormones) in the leaching water to the outside. . In addition, regarding the removed solidified salt, the necessary processing method is adopted in accordance with the review of the regeneration or disposal method to determine the required properties, etc. 1243155 V. Description of the invention (4) [Simplified description of the drawing] Figure 1 The 'shown' is a flowchart showing the first embodiment of the present invention, which is a process of desalination by crystallization. The one shown in FIG. 2 is a flowchart showing a second embodiment of the present invention, which is a process of desalting by crystallization after biological treatment. The one shown in FIG. 3 is a flowchart showing a third embodiment of the present invention, which is a process of desalting by a vacuum drum dryer. [Preferred Specific Embodiment of the Invention] The descriptions of the same parts in the drawings are the same. Next, an embodiment of the present invention will be described with reference to the drawings. Fig. 1 is a first embodiment of the present invention. In the method for treating water seepage in a coating type final treatment field, a method of desalting by crystallization is performed. In the final treatment site of general waste or business waste, in order to stabilize and harmless the waste, the covered waste is sprinkled with water, but the covered type is the closed system waste final treatment. In the field, the concentration of exudated water is increased due to the control of the amount of water sprayed. For example, the chloride ion concentration of the exuded water is approximately doubled, and desalination treatment is performed. In addition, the amount of organic matter (BOD, COD, etc.) contained in the effluent water depends on the content of the waste. In order to release desalinated water, it is necessary to perform an organic matter removal treatment that meets the discharge standard. In the first embodiment of the present invention shown in FIG. 1, the sprinkler (2) is used to sprinkle water on the waste (1) of the coating type final treatment site, and the obtained seepage water containing a high concentration of salt is sprayed. (3) Desalting, first remove the effluent from the exudate 1243155 V. Description of the invention (5) The Ca component in the high-concentration salt contained. That is, the effluent water containing a high concentration of salt is introduced into a Ca component removal water tank, and Na2C03 and a coagulant are added. Therefore, CaC03 precipitate is formed, and at the same time, a part of organic matter is aggregated and precipitated. The precipitate is dehydrated by a dehydrator, and the precipitated sludge separated by dehydration is discharged to a predetermined external disposal site, and the separated water by dehydration will be separated. It will be sent back to the inlet area of the Ca component removal water tank, and reprocessed together with the seepage water. On the other hand, the intermediate treated water after the Ca component removal from the Ca component removal water tank is removed is introduced into the crystallization salt solidification apparatus. Here, when the amount of seepage water (3) containing high-concentration salt obtained by spraying the waste (1) of the coating type final treatment site with a sprinkler device (2) is "W", The amount of intermediate treatment water introduced into the crystallization salt solidification apparatus for removing Ca components and the like is also "W", which is equal to the amount of 槪. Therefore, the removal of Ca components from the effluent water of the waste can prevent Ca damage. In other words, when the Ca component is contained in the oozing water, the amount of scale attached to the heat transfer tube and the like will increase, and the pretreatment such as Ca precipitation can reduce the amount. In this case, it is better to check the insulation, or it is necessary to pay attention not only to the adhesion of Ca components, but also to the adhesion of silicon scale. In addition, although the precipitation rate of CaC03 is fast, since it is easy to precipitate and solidify at the bottom of the tank, it is preferable to adjust it to discharge continuously and stably. The intermediate treatment water after the removal of the Ca component is introduced into a crystallization and salt solidifying device ', and is desalted by a crystallization method. Here, the crystallization method which is exactly the evaporation method 1243155 5. Description of the Invention (6) uses a steam nozzle. The supplied steam is produced by introducing industrial water into the boiler, and its amount is about 0.5W. Also, in this case, it is necessary to pay attention to the scattering of organic matter and harmful trace substances exuding in the water. It is more suitable to be sucked by a vacuum device on the one hand, and it can be operated only at low temperature. The solid salt discharged near the bottom of the crystallization device is dehydrated by a dehydrator, and the dehydrated and separated solid salt is removed, and the obtained high-purity salt is removed to the outside without heating treatment such as grilling. In addition, in the crystallization apparatus, it is advantageous because the amount of vapor can be halved by using an ejector, and therefore the energy is small. In addition, the crystallization method requires a basket of techniques for continuous transfer operations because it collects salt slurry. In addition, since the bottom of the tank of the crystallization device is prone to blockage due to solid salt, it can be prevented by stirring or the like, and at the same time, the flow rate can be used to prevent the blockage. In addition, it is preferable to make the load or slurry concentration of the device at an appropriate level and operate it at a certain level. According to the present invention, the demineralized water flowing out of the crystallization device is 1.0W of 1.5W, which can be recycled (meaning recycled) for use as water for sprinkler water in the treatment plant. Therefore, in order to carry out the drainage, the residual part of the 0.5W desalinated water was biologically treated to decompose the organic matter contained therein, the biological sludge was aggregated and precipitated, and further treated with sand filtration and activated carbon, and then reused. Treated as industrial water or discharged. In addition, the precipitate precipitated by agglutination in the agglutination and precipitation step, the above 1243155 V. Description of the invention (7) The CaC032 precipitate is sent to a dehydrator, where it is dehydrated together with the precipitate of CaC03. When the treated water is reused as industrial water, the treated water at (5) .5W is converted into steam by a boiler and supplied to the injector of the above-mentioned crystallization device. Or, in the case of reuse as industrial water, the treated water system of () .5W is used as make-up water for the cooling tower. Therefore, according to the method for treating the seepage water in the coating type final treatment plant according to the first embodiment of the present invention, the seepage water containing a high concentration of salt generated by sprinkled water on the covered general waste or business waste is desalted and Recycling the desalinated water in the treatment plant can achieve the effect of detoxifying and stabilizing the coating-type final treatment plant. In addition, for equipment that treats the seepage from general waste or business waste from the coating type final treatment site, it is necessary to be careful of scaling adhesion, blocking, and corrosion at the same time when handling the seepage from high concentrations of salt and so on. And so on, and be careful not to cause organic matter, trace amounts of harmful substances, etc .: Scattering. For example, to prevent corrosion, you can use an extremely low temperature program and machine disease to prevent corrosion. In the case of an unexpectedly high temperature, ’pitting corrosion may occur due to chloride ions (c Γ). Materials such as titanium, which can resist stress corrosion, can be used. In particular, attention should be paid to the decay of heat transfer tubes and the like. Where stainless steel is used, electrical corrosion protection should be considered. With regard to environmental protection, in order to prevent trace amounts of harmful substances such as organic substances, heavy metals, and dioxin (hereinafter referred to as DXN) from flying to the environment, maintenance and management should be fully performed, and environmental analysis should be carried out regularly. For DXN, through biological treatment, sand filtration-9- > and activity 1243155 V. Description of the invention (8) Carbon treatment, it can reach a legal cleanliness as low as 10 pg-TEG / L. Moreover, in the case of higher than the legal threshold, a DXN removal device in water can be installed. Regarding biological treatment, a small amount of organically treated microorganisms inhabiting the symbiosis of freshwater and seawater can be used to domesticate microorganisms with a certain salt concentration. The method shown in FIG. 2 is a second embodiment of the present invention, which is a method for treating seepage water from general waste or business waste in a coating-type final treatment plant. After biological treatment, a crystallization method is performed. Desalination process. When the seepage water from the coating type final treatment plant is directly treated with salt curing equipment, organic substances or trace harmful substances are mixed into the generated salt, and it is expected that it will be difficult to effectively use or recycle or dispose of the generated salt. Therefore, it is necessary to heat or grill the generated salt. Here, in the second embodiment of the present invention shown in FIG. 2, the sprinkler device (2) is used to sprinkle water on the waste (1) of the coating type final treatment site, and the obtained concentration is high. The salt oozing water (3) is desalted, and as in the case of the above-mentioned Example 1, first, the Ca component is removed. Since the salt concentration of the intermediate treatment water after removing the Ca component is high, the biological treatment will be damaged by the salt and cannot be reached. Therefore, it is better to dilute the salt concentration with water to make it a certain concentration of desalinated water that is lighter than seawater. . Therefore, 2W dilution water is added to the intermediate treatment water W after removing the Ca component, and the obtained 3W mixture water is introduced into the biological treatment equipment to decompose the organic matter contained in the biological treatment, so that the biological sludge is aggregated and precipitated, and further Carry out sand filtration and activated carbon treatment. Therefore, the treated water after sand filtration and activated carbon treatment is introduced into a crystallization salt solidification device, and desalted by a crystallization method. -10- 1243155 V. Description of the invention (9) Here, the crystallization method which is exactly the evaporation method is implemented, and a steam nozzle is used. The supplied steam is about 1.5W when the industrial water is introduced into the boiler. Also, in this case, it is preferable that the suction is performed by a vacuum device, and the operation can be performed only at a low temperature. The solid salt discharged near the bottom of the crystallization device is dehydrated by a dehydrator, and the dehydrated and separated solid salt is removed, and the obtained high-purity salt is removed to the outside without heat treatment such as grilling. In addition, when the amount of treated water diluted with water reaches several times, the salt curing equipment for subsequent desalination will become larger. Because the required energy becomes larger, it is better to pay attention not to increase the amount of treated water diluted with water too much. . According to the present invention, the 4.5W desalinated water flowing out of the crystallization device, of which 1 · 0W is recycled (meaning recycled) is used as the sprinkler water in the treatment plant, and 2.0W is recycled and reused as For biologically treated dilution water, the remaining 0.5W is reused as industrial water treatment water, or it is discharged. In addition, the precipitate precipitated by agglutination in the agglutination and precipitation step, the above-mentioned precipitate of CaC03 is sent to a dehydrator, where it is dehydrated together with the precipitate of CaC03. When the 1.5 W treated water is reused as industrial water, the treated water is converted into steam by a boiler and supplied to the ejector of the crystallization device. Or, in the case of reuse as industrial water, the treated water system of 1.5 W is used as make-up water for the cooling tower. Therefore, the method of treating seepage water in a coating-type final treatment plant according to the second embodiment of the present invention will cover the covered general waste or business waste. 11-1243155 V. Description of the invention (1〇) The produced seepage water containing high concentration of salt is desalinated, and the desalinated water is recycled and reused in the treatment plant, which can achieve the effect of detoxifying and stabilizing the coating type final treatment plant. Fig. 3 shows a third embodiment of the present invention, which is a method for treating seepage water from general waste or business waste in a coating type final treatment plant, and a vacuum desiccator is used to perform desalination. . In the case of relatively small amount of organic matter and trace harmful substances in the seepage water in the coating type final treatment plant, the seepage water system is directly treated with the salt curing equipment, the amount of treated water is reduced, and the treatment time is also reduced, which is advantageous. Here, in the third embodiment of the present invention shown in FIG. 3, the sprinkler (2) is used to sprinkle water on the waste (1) of the coating type final treatment site, and the obtained high-concentration The salt effluent (3) is desalted, and as in the case of the above-mentioned Example 1, the Ca component is first removed. Next, the intermediate treatment water W after removing the Ca component is processed and desalted by a direct salt curing device made by a drum dryer. In direct drying equipment such as drum dryers, due to the need to pay attention to the scattering of organic matter and harmful trace substances in water, for example, the structure of a closed device such as a drum dryer that is operated under vacuum must be used. In addition, the energy consumption is relatively large, and the high-pressure steam obtained from the boiler is simultaneously evaporated by a drum dryer, and the steam is cooled by the cooling water from the cooling tower through the heat exchanger to obtain degassing. brine. The high-pressure steam drainage in the drum dryer is returned to the drum chamber for reuse. The solid salt discharged near the bottom of the drum dryer is dehydrated by a dehydrator -12-1243155 V. Description of the invention (11), the solid salt separated by dehydration is removed, without heating treatment such as barbecue, etc. The obtained high-purity salt is removed to the outside. According to the present invention, 1.0 W of the desalinated water flowing out of the storage area of the drum dryer can be recycled (that is, recycled) as the sprinkler water in the treatment plant. Therefore, in order to release, the organic matter contained in the demineralized residue is decomposed by biological treatment, the biological sludge is aggregated and precipitated, and further processed by sand filtration and activated carbon, and then reused as industrial water. Treat water or release it. The precipitate precipitated by agglutination in the agglutination and precipitation step is omitted in the illustration. The above-mentioned CaC03 precipitate is sent to a dehydrator, where it is dehydrated together with the CaC03 precipitate. When the treated water is reused as industrial water, the 1.0W treated water system is used as make-up water for the cooling tower. Therefore, according to the method for treating the seepage water in the coating type final treatment yard according to the third embodiment of the present invention, the seepage water containing a high concentration of salt generated by sprinkled water on the covered general waste or business waste is desalted, Recycling the desalinated water in the treatment plant will achieve the effect of detoxifying and stabilizing the coating-type final treatment plant.
