Abstract

본 발명은 연속적인 역세를 위해 농축수를 재활용하고 또한 세정성능을 향상시키기 위해 간헐적으로 가압공기를 사용하는 분리막 장치 전처리 여과장치의 세척방법에 관한 것으로, 유입수(1)가 유입펌프(2)에 의해 응집처리계(3)를 통하여 여과장치(4)에 이송되어 여과되며 여과수는 고압펌프(5)에 의해 분리막장치(6)에 이송되어 유입된 여과수는 분리막에 의해 투과수(7)와 농축수(8)로 분리되고 투과수(7)는 재활용하고 분리막장치(6)에서 배출된 농축수(8)를 역세과정에 세척수로 보조여과장치(4′)에 공급하고 현재 여과되고 있는 여과장치(4)가 역세할 시점에 발브조작에 의해 보조여과장치(4′)는 투과하고 여과장치(4)는 농축수(8)에 의해 계속하여 역세하면서 역세수(9)를 배출하는 것을 특징으로 하는 분리막장치 전처리 여과장치의 세척방법.The present invention relates to a method of washing a membrane device pretreatment filtration device using intermittent pressurized air to recycle concentrated water for continuous backwashing and to improve cleaning performance. The filtrate is transferred to the filtration device 4 through the coagulation treatment system 3 and filtered. The filtrate is transferred to the membrane device 6 by the high pressure pump 5, and the filtered water is concentrated with the permeate 7 by the separation membrane. The filtration apparatus, which is separated into water (8), recycles permeate (7) and recycles the concentrated water (8) discharged from the membrane device (6) to the auxiliary filtration device (4 ') as washing water during backwashing. At the time when (4) is backwashed, the auxiliary filtration device 4 'is permeated by the valve operation, and the filtration device 4 discharges the backwash water 9 while continuously backwashing with the concentrated water 8. Method of washing the membrane filter pretreatment filtration device.
