Description
Claims (4)
- 폐수 유입관에 의해 외부의 폐수와 광촉매가 유입되며, 광조사램프에 의하여 처리되는 광산화 반응조;상기 광산화 반응조에서 처리된 처리수를 pH 조절에 의하여 광촉매를 침전시켜 처리수로부터 광촉매를 제거시키는 침전조;상기 광촉매가 제거된 처리수에 잔존하는 광촉매를 분리하는 진공펌프가 구비된 분리막 모듈이 설치된 분리막 탱크;로 구성되는 것을 특징으로 하는 광산화 수처리 장치.
- 제1항에 있어서,상기 침전조에서 침전되지 않은 잔존 광촉매를 상기 분리막 탱크에서 처리수를 pH 6.5 내지 7.0의 범위로 조절하여 응집제로서 0.01 내지 0.2 g/L의 FeCl3를 추가하는 것을 특징으로 하는 광산화 수처리 장치.
- 외부의 폐수와 광촉매를 광조사램프가 구비된 광산화 반응조에 유입되는 단계;상기 광산화 반응조에서 광산화 램프에 의하여 폐수를 처리하는 단계;상기 광산화 반응조에서 처리된 처리수를 침전조에 유입시켜 5.5 내지 6.5 범위의 pH로 조절하여 광촉매를 침전시키는 단계;상기 침전수의 상등액을 진공펌프가 구비된 침지형 분리막 모듈이 설치된 분리막 탱크에 유입시켜 상기 분리막에 의하여 잔존 광촉매를 분리하는 단계;로 구성되는 것을 특징으로 하는 폐수의 광산화 수처리 방법.
- 제3항에 있어서,상기 분리막 탱크에서 처리수를 pH 6.5 내지 7.0의 범위로 조절하여 응집제로서 0.01 내지 0.2 g/L의 FeCl3 를 첨가하는 것을 특징으로 하는 광산화 수처리 방법.
