본 고안은 생물학적 폐수처리시설에서 발생한 잉여슬러지의 감량설비에 관한 것으로, 특히 가용화장치를 갖춘 대도시의 대규모 폐수처리시설과 소도시의 마을하수처리장을 연계하여, 상기 마을하수처리장에서 발생한 잉여슬러지를 대규모 폐수처리시설에 설비된 가용화장치로 처리할 수 있도록 하는 구체적인 수단을 제공함으로써, 마을하수처리장에서 발생한 잉여슬러지를 감량할 수 있음은 물론이고, 가용화장치를 갖춘 폐수처리시설을 보다 효율적으로 운용할 수 있도록 하는, 가용화장치를 갖춘 폐수처리시설에 있어서의 마을하수처리장에서 발생한 잉여슬러지 감량설비에 관한 것이다.The present invention relates to a facility for reducing excess sludge generated from biological wastewater treatment facilities. In particular, the large sludge wastewater treatment facility in a large city equipped with an solubilization system and the village sewage treatment plant in a small city, the large sludge produced in the village sewage treatment plant By providing specific means to be treated by the solubilizer installed in the treatment facility, it is possible to reduce surplus sludge generated in the village sewage treatment plant and to operate the waste water treatment facility equipped with the solubilizer more efficiently. The present invention relates to an excess sludge reduction facility generated in a village sewage treatment plant in a wastewater treatment facility equipped with a solubilization device.

현재 하수 및 오폐수의 처리시설에는 생물학적 폐수처리시설이 널이 이용되고 있는바, 상기 생물학적 폐수처리시설의 일반적인 구성을 도 1을 참고하여 하기에서 살펴본다.Currently, the wastewater and wastewater treatment facilities have biological wastewater treatment facilities, which are used in the board. A general configuration of the biological wastewater treatment facilities will be described below with reference to FIG. 1.

일반적으로 생물학적 폐수처리시설은, 외부로부터 유입되는 폐수를 1차 물리적으로 처리하는 침사시설(110)과, 폐수 유입량의 변동에 적절히 대응할 수 있도록 하는 유량조정조(120)와, 유입된 폐수를 생물학적으로 정화하는 생물반응조(130)와, 상기 생물반응조(130)를 거친 폐수에서 슬러지를 침전시켜 정화된 폐수와 슬러지를 분리하는 침전조(140)와, 상기 슬러지가 제거된 폐수를 소독하여 방류하는 소독방류조(150) 및, 상기 침전조(140)에서 분리된 슬러지 중 생물반응조(130)에서 필요로 하는 반송슬러지 이외에 잉여슬러지를 탈수하여 외부로 반출하는 탈수장치(160)로 구성된다.In general, the biological wastewater treatment facility includes a sedimentation facility 110 for physically treating wastewater introduced from the outside, a flow adjustment tank 120 for properly coping with fluctuations in wastewater inflow, and biologically A bioreactor 130 for purification, a sedimentation tank 140 for separating sludge from the purified wastewater and sludge by sedimenting the sludge from the wastewater passing through the bioreactor 130, and a disinfection discharge for discharging and discharging the wastewater from which the sludge has been removed. The tank 150 and a dewatering device 160 for dewatering excess sludge and carrying it out to the outside in addition to the return sludge required by the bioreactor 130 among the sludge separated from the settling tank 140.

한편, 상기와 같은 일반적인 생물학적 폐수처리시설은 필연적으로 슬러지가 발생하는데, 앞서 살펴본 바와 같이 폐수의 처리과정에서 발생한 슬러지는 일부 생물반응조(130)로 반송하여 하수 유기물의 흡착 및 산화에 유효한 미생물원으로 공급하고, 나머지의 잉여슬러지는 상기 탈수장치(160)를 거쳐 케이크 형태로 외부로 반출하되 최종적으로는 해양투기, 퇴비화, 소각, 매립과 같은 방법으로 처리하는바, 그 대부분은 해양투기로 이루어진다.On the other hand, sludge is inevitably generated in the general biological wastewater treatment facilities. As described above, sludge generated during the treatment of wastewater is returned to some bioreactors 130 as a microbial source effective for adsorption and oxidation of sewage organic matter. After supplying the remaining excess sludge to the outside through the dehydration device 160 in the form of a cake, but finally treated by the method such as ocean dumping, composting, incineration, landfill, most of it consists of ocean dumping.

그러나 상기 해양투기의 경우 2012년 전면적으로 금지됨에 따라, 생물학적 폐수처리시설에서 발생한 슬러지의 처리방법과 함께 슬러지의 발생량을 최소화할 수 있는 기술개발을 필요로 하게 되었고, 그 결과 잉여슬러지를 감량할 수 있는 다 양한 형태의 가용화 기술이 국내외에서 실용화되고 있다.However, since the offshore dumping was completely banned in 2012, it was necessary to develop a technology for minimizing the amount of sludge generated along with the treatment method of sludge generated in a biological wastewater treatment facility, and as a result, it was possible to reduce excess sludge. Various types of solubilization techniques have been put to practical use at home and abroad.

상기 공지의 슬러지 가용화 기술에 대하여 좀 더 구체적으로 살펴보면, 가용화 기술은 일반적인 생물학적 폐수처리시설에서 발생한 슬러지의 80%이상이 유기물로 이루어져 있다는 것에서 착안하여, 상기 슬러지를 파괴하여 생물반응조(130)의 미생물의 먹이가 될 수 있도록 함으로써, 결과적으로 잉여슬러지를 물과 이산화탄소로 분해하는 기술로서, 상기 슬러지의 파괴 방법에는 기계적 파쇄, 가열, 동결, 해동, 압력 등을 이용한 물리적 처리와, 오존 등 산화제를 이용한 화학적 처리 및 호열미생물을 이용한 생물학적 처리가 있고, 이러한 처리방법을 개별적 또는 복합적으로 병행함으로써 슬러지를 파괴하여 가용화 하는 방법이 공지되어 있다.Looking at the known sludge solubilization technology in more detail, the solubilization technology is focused on the fact that more than 80% of the sludge generated in the general biological wastewater treatment facility consists of organic matter, destroying the sludge to microorganisms of the bioreactor 130 As a result, the excess sludge is decomposed into water and carbon dioxide, and the sludge destruction method includes mechanical crushing, heating, freezing, thawing, pressure, and physical treatment using an oxidizing agent such as ozone. There are chemical treatments and biological treatments using thermophilic microorganisms, and methods of destroying and solubilizing sludge by combining these treatment methods individually or in combination are known.

그리고 상기 슬러지 가용화 기술을 폐수처리시설에 적용할 수 있도록 하는 다양한 형태의 가용화장치 또한 공지된바, 이하 도 2를 참고하여 통상의 가용화장치를 갖춘 폐수처리시설의 개략적인 구성을 살펴보면, 통상의 침사시설(110)·유량조정조(120)·생물반응조(130)·침전조(140)·소독방류조(150)가 순차적으로 형성된 일반적인 생물학적 폐수처리시설에 있어서, 상기 침전조(140)에서 분리된 슬러지 중에서 반송슬러지 이외의 잉여슬러지를 유입하여 가용화 한 후 생물반응조(130)로 다시 유입하는 가용화장치(200)를 더 포함하는바, 상기 가용화장치(200)는 앞서 설명한 바와 같이 다양한 형태가 공지되어 있는데, 그 세부구성에 관계없이 슬러지를 파괴하여 생물반응조(130)에서 필요로 하는 탄소원이나 미생물의 먹이 가 될 수 있도록 한다.In addition, various types of solubilization apparatuses for applying the sludge solubilization technology to a wastewater treatment facility are also known. Hereinafter, referring to FIG. 2, a schematic configuration of a wastewater treatment facility equipped with a conventional solubilization device may be used. In the general biological wastewater treatment facility in which the facility 110, the flow adjustment tank 120, the bioreactor 130, the sedimentation tank 140, and the disinfection discharge tank 150 are sequentially formed, the sludge separated from the sedimentation tank 140 is included. The solubilizer 200 further includes a solubilizer 200 which flows into the bioreactor 130 after solubilizing the excess sludge other than the carrier sludge, and the solubilizer 200 is known in various forms as described above. Regardless of its detailed configuration, the sludge is destroyed to be a carbon source or microorganism food required by the bioreactor 130.

그러나 상기와 같은 가용화장치(200)를 갖춘 폐수처리시설의 경우, 가용화장치(200)의 설치 및 운영에 상당한 비용을 소요함에 따라, 대도시의 대규모 생물학적 폐수처리시설에 주로 적용되었을 뿐, 여타 소도시의 마을하수처리장과 같이 50~100톤/일 규모의 중소규모 생물학적 폐수처리시설에서는 현실적으로 그 설치가 어렵고, 이러한 이유로 인하여 슬러지를 감량할 수 있는 가용화장치가 이미 개발되었음에도 불구하고 마을하수처리장에서 발생한 잉여슬러지의 대부분이 해양투기 등과 같은 방법으로 처리되는 문제점이 있었다.However, in the case of the wastewater treatment facility equipped with the solubilization device 200 as described above, the installation and operation of the solubilization device 200 requires a considerable cost, and thus is mainly applied to a large-scale biological wastewater treatment facility in a large city. In small and medium sized biological wastewater treatment facilities of 50 ~ 100 tons / day, such as village sewage treatment plants, it is difficult to install them, and for this reason, surplus sludge generated in village sewage treatment plants has been developed even though solubilizers have been developed to reduce sludge. Most of the problems have been dealt with in the same way as ocean dumping.

본 고안은 위와 같은 문제점을 해결하기 위한 것으로, 가용화장치를 갖춘 대도시의 대규모 생물학적 폐수처리장과 소도시의 마을하수처리장을 연계하여, 마을하수처리장에서 발생한 잉여슬러지를 기설치된 가용화장치로 처리할 수 있도록 함으로써, 마을하수처리장의 잉여슬러지를 감량할 수 있음과 아울러 대규모 생물학적 폐수처리시설에 설치된 가용화장치를 더욱 효율적으로 운용하는 것을 목적으로 하는바, 가용화설비를 갖춘 폐수처리시설에 마을하수처리장에서 수거한 잉여슬러지를 저류 및 농축한 후, 농축된 슬러지에서 협잡물을 제거한 다음 가용화장치에 선택적으로 유입할 수 있도록 하는 잉여슬러지 감량설비를 구성한다.The present invention is to solve the above problems, by linking a large biological wastewater treatment plant in a large city with a solubilization device and a village sewage treatment plant in a small city, so that the excess sludge generated in the village sewage treatment plant can be treated with an installed solubilizer. In addition, it is possible to reduce surplus sludge in village sewage treatment plants, and to operate solubilizers installed in large-scale biological wastewater treatment facilities more efficiently.The surplus collected from village sewage treatment plants in solubilization facilities After the sludge has been stored and concentrated, excess sludge reduction equipment is constructed to remove contaminants from the concentrated sludge and to selectively enter the solubilizer.

상기와 같은 목적을 달성하기 위한 본 고안의 구성은, 통상의 침사시설·유량조정조·생물반응조·침전조·소독방류조를 순차적으로 형성하되, 상기 침전조에서 분리된 슬러지 중 생물반응조로 직접 유입되는 반송슬러지 이외의 잉여슬러지를 유입하여 생물반응조에 필요한 탄소원 및 미생물의 먹이가 될 수 있도록 상기 잉여슬러지를 파괴하여 생물반응조로 유입하는 통상의 가용화장치를 갖춘 폐수처리시설에 있어서, 중소규모의 마을하수처리장에서 수거한 잉여슬러지를 유입하여 저장하는 저류조를 형성하고, 상기 저류조로부터 공급되는 슬러지를 농축하는 농축조를 형성하되 상기 침전조에서 가용화장치로 유입되는 잉여슬러지가 상기 농축조를 거 쳐 가용화장치로 유입되도록 하며, 상기 농축조에서 가용화장치로 연결된 슬러지가용화라인에는 마이크로스크린을 설치하여 협잡물을 제거할 수 있도록 하는 한편, 상기 농축조에 탈수장치유입라인을 더 형성하여 농축된 슬러지를 통상의 탈수장치로 유입할 수 있도록 함으로써, 농축조의 슬러지를 가용화장치 또는 탈수장치에 선택적으로 유입할 수 있도록 한, 가용화장치를 갖춘 폐수처리시설에 있어서의 마을하수처리장에서 발생한 잉여슬러지 감량설비에 그 특징이 있다.Constitution of the present invention for achieving the above object, the formation of a conventional sedimentation facility, flow adjustment tank, bioreaction tank, sedimentation tank, disinfection tank in order to return, the sludge separated from the sedimentation tank directly introduced into the bioreactor A small and medium-sized village sewage treatment plant in a wastewater treatment facility equipped with a conventional solubilization device that destroys the surplus sludge and introduces it into the bioreactor so that surplus sludge can be introduced to feed the carbon source and microorganisms necessary for the bioreactor. Form a storage tank for entering and storing the excess sludge collected in the storage, and to form a concentration tank for condensing the sludge supplied from the storage tank, the surplus sludge flowing from the sedimentation tank to the solubilizer is introduced to the solubilizing device through the concentration tank. In the sludge solubilization line connected to the solubilizer in the concentration tank By installing a micro screen to remove impurities, while forming a dewatering device inlet line in the thickening tank to allow the introduced sludge into the normal dewatering device, the sludge of the thickening tank to the solubilizer or dewatering device It is characterized by a surplus sludge reduction facility generated in a village sewage treatment plant in a wastewater treatment plant equipped with a solubilization device that can be selectively introduced.

상기와 같은 본 고안에 의하면, 소도시의 마을하수처리장에서 발생한 잉여슬러지를 가용화장치가 구비된 대규모 폐수처리시설과 연계하여 처리할 수 있음으로써, 결과적으로 마을하수처리장에서 발생한 잉여슬러지를 감량할 수 있음과 아울러 마을하수처리장에 고가의 가용화장치를 설비하지 않아도 되므로 그에 따른 설비 및 운영비를 절감할 수 있으며, 가용화장치를 갖춘 대규모 폐수처리시설의 입장에서는 기존 설비를 적극 활용하게 됨으로써 효율적인 운용이 가능하다.According to the present invention as described above, it is possible to reduce the excess sludge generated in the village sewage treatment plant by treating the excess sludge generated in the village sewage treatment plant of a small town in connection with a large-scale wastewater treatment facility equipped with a solubilization device. In addition, it is not necessary to install expensive solubilizer in the village sewage treatment plant, thereby reducing the equipment and operation cost. Also, in the case of large-scale wastewater treatment facilities equipped with solubilizer, it is possible to efficiently operate existing facilities.

Euverink et al. IN THE NETHERLANDS, wastewater is treated in plants with the sole purpose of meeting the water standards specified by the Pollution of Surface Waters Act (see Chapters 1 and 11), which prohibits the discharge of polluting or harmful sub-stances into surface waters without a license. As a consequence of this act, sewage treatment plants were built, mainly to reduce chemical oxygen demand (COD) and the amounts of phosphates and nitrogen present in wastewater. Since 1998, all water in Dutch sewage networks is treated, and almost all households have been connected to municipal sewage treatment (EEA 2005).
