Abstract
폐수를 중화 장치 및 화학 침전 처리 장치로 통과시키고, 상기 화학 침전 처리 장치로부터 유출수를 마이크로 필트레이션 장치로 통과시키고, 상기 마이크로필트레이션 장치로부터의 유출수를 나노필트레이션 장치로 통과시키는 공정을 포함하는 폐수 처리 방법에 있어서, 폐수 재이용을 방해하는 성분을 무기 이온을 고농도로 함유하는 폐수로부터 제거하는 폐수 처리 방법은 막 오염에 따른 플럭스 감소를 방지하고, 처리수의 수질을 향상시키며, 세척 주기를 증가시키는 장점이 있는 효율적이고, 경제적이며 단순한 무-방류 시스템이다.Wastewater comprising passing the wastewater through a neutralization device and a chemical precipitation treatment device, passing the effluent from the chemical precipitation treatment device to a microfiltration device, and passing the effluent from the microfiltration device to a nanofiltration device. In the treatment method, a wastewater treatment method that removes components that interfere with wastewater reuse from wastewater containing high concentrations of inorganic ions prevents flux reduction due to membrane contamination, improves the water quality of the treated water, and increases the washing cycle. It is an efficient, economical and simple zero discharge system with the advantages.
