Abstract

본 발명은 폐수를 여과 처리하면서 필요한 시기에 장치를 해체함이 없이 처리된 폐수의 레벨차를 이용해서 여과재를 효율적이고 경제적으로 역세척이 가능한 폐수의 여과처리방법 및 이에 사용하기 위한 장치를 제공하기 위한 것이다.The present invention provides a method for filtration and treatment of wastewater in which the filter medium can be efficiently and economically backwashed using the level difference of the treated wastewater without dismantling the device at a necessary time while filtering the wastewater. It is for.

본 발명은 정화된 폐수의 레벨차를 감지하는 스위치에 의해 피처리 폐수의 유입관의 솔레노이드 밸브를 개폐함과 동시에 역 세척수를 배출하는 유출구의 밸브도 조절하여 정화된 폐수를 자연 중력하에 유출구로 배출시키면서 오염물질이 부착된 분리막 또는 필터를 역 세척할 수 있는 장치와 방법임을 특징으로 한다.The present invention opens and closes the solenoid valve of the inlet pipe of the wastewater to be treated by a switch for detecting the level difference of the purified wastewater and at the same time controls the valve of the outlet for discharging the backwash water, and discharges the purified wastewater to the outlet under natural gravity. It is characterized in that the apparatus and method for backwashing the membrane or filter attached to the contaminants.
