Abstract:
본 발명은 발라스트수 내에 포함되어 있는 미생물 및 기타 입자성 물질을 효과적으로 제거할 수 있는 분리막을 이용한 발라스트수 처리장치 및 이를 이용한 발라스트수 처리방법에 관한 것으로서, 본 발명에 따른 분리막을 이용한 발라스트수 처리장치는 선박의 일측에 구비되어 해수를 취수하는 취수 펌프와, 취수된 해수 내에 포함되어 있는 미생물 및 입자성 물질을 걸러내는 분리막 및 상기 분리막을 통과한 처리수를 저장하는 발라스트 탱크를 포함하여 이루어지는 것을 특징으로 한다. 역세척용 탱크가 더 구비되며, 상기 발라스트 탱크 내의 처리수가 상기 역세척용 탱크에 역세척수의 용도로 공급되며, 상기 역세척용 탱크는 상기 분리막에 역세척수를 공급하여 상기 분리막 상의 이물질을 제거할 수 있다. 발라스트수, 분리막
Abstract:
PURPOSE: A wastewater treatment system and a method thereof using a phosphorus filter tub and a membrane separation device are provided to enable smooth phosphorus release from anaerobic tank and remove most of the phosphorus included in the inflow water by solving the dentirfyed microorganism which can be generated in the denitrifier and organic competition of phosphorus storage microorganism. CONSTITUTION: A wastewater treatment system include a pre-denitrification tub(10), an anaerobic tank(20), a phosphorus filtering tub(30), a first intermittently aerating tank(40) and a second intermittently aerating tank(50). The pre-denitrification tub denitratifies the nitrate nitrogen and nitrite nitrogen including within the wastewater and return sludge. The anaerobic tank release the phosphorus within inflow water by being supplied with a inflow water from the pre-denitrification tub. The phosphorus filter tub collects phosphorus which is released from the anaerobic tank by being including in the end part of the anaerobic tank. The first intermittently aerating tank and the second intermittently aerating tank are successively included in the backend the phosphorus filtering tub. The sedimentation type membrane separation apparatus is included within the second intermittently aerating tank. The sludge emitting the phosphorus within the anaerobic tank and the effluent which the phosphorus is accumulated are provided to the filtering tub and has a media which absorbs and collects phosphorus within the phosphorus filtering tub.
Abstract:
PURPOSE: A biological sewage processing device including a continuous reaction bath and a sewage processing method using the same are provided to increase processing efficiency of biological nitrogen and phosphorous. CONSTITUTION: A biological sewage processing device including a continuous reaction bath includes a reactor bath(1), a mixer(2), a diffuser(3), a sewage inflow part(4), a control part(6), and a reaction bath water level sensor(7). The mixer is equipped inside the reaction bath. The diffuser is formed on the bottom of the reaction bath. The sewage inflow part is connected to a side of ht reaction bath. A treated water drawing part is connected to the bottom of the reaction bath.
