초록

본 연구에서는 스테인레스 스틸 제조공장에서 배출된 유출수를 막기술 및 물리화학적인 처리 가능성에 대하여 알아보았다. 스테인레스 스틸 제조 공장에서 배출된 유출수의 초기 투과 플럭스는 1.2 L/㎡·h 이었으며, 2 h 후에는 투과 플럭스가 0.5 L/㎡·h 로 감소하였다. RO에 의한 크롬(Ⅵ), TDS 및 불소의 제거율은 각각 99.8, 96.1 및 96.1%로 높에 나타났으나, COD 제거율은 79.1%로 다소 낮게 나타났다. 페놀의 제거율은 6.7%로 매우 낮아 RO로 처리할 수 없다는 것을 알았다. 또한 이온교환수지(0-80 BV)에 의한 RO 투과수의 농도는 68 mg/L에서 0.01 mg/L까지 줄일 수 있었으며, 과산화수소에 의한 페놀과 COD의 평균 제거율은 각각 95.0 및 62.8%이었다.

This paper investigates the possibilities of treatment of effluent from stainless steel manufacturing plants by membrane technology and physico-chemical treatments. The initial permeate flux of the effluent was 1.2 L/㎡·h. The permeate flux decreased to 0.5 L/㎡·h and stabilized after 2 hrs. The removal rates of Cr(Ⅵ), TDS and F by revere osmosis (RO) were found to be 99.8, 96.1 and 96.1%, Respectively, but that of COD was somewhat low at 79.1%. It was revealed that we could not use RO to remove phenol because the removal rate of 6.7% was too low. On the other hand, we were able to decrease the concentration of RO permeate, from 68 mg/L to 0.01 mg/L, by an ion-exchange method(0-80 BV). The average removal rates of phenol and COD using hydrogen peroxide were 95.0% and 62.8%, respectively.
