Settle and separate the supernatant with supernatant and settling sludge. And sterilization and coagulation sedimentation of SS by ozone treatment and sent to fluidized bed sand filter Secondly, SS is removed and sent to the ultrafiltration membrane separation device, and the sedimentation sludge leaves about 1/10 to 1/3 of the capacity of the digester, and the surplus is sent to the dehydrator to separate the solids and the solids are stored in the storage room. The filtrate is sent back to the reservoir for reprocessing.

한외여과막 장치로 보내진 상등 배출수는 이 장치에서 잔존 SS및 BOD,COD를 보다 확실히 분리제거 신킨후 방류하거나 필요에 따라 활성탄 흡착장치로 보내 충분하게 처리한 후 방류하는 분뇨 및 고농도유기 오.폐수의 고도처리방법.The upper effluent sent to the ultrafiltration membrane is separated and removed from the SS, BOD, and COD to be discharged more reliably and discharged, or sent to the activated carbon adsorption system if necessary for sufficient treatment and discharge of manure and high concentration organic wastewater. Treatment method.
