Abstract

We develop advanced oxidation processes for the treatment of spent electroless nickel plating solution. Apart form recovering nickel by leaching and enrichment, more emphasis is placed on rendering the waste water recyclable via oxidizing phosphite and hypophosphite into phosphate which can then be precipitated easily. $UV/H_2O_2$ process is employed and the conversion efficiency of COD and $PO_4-P$, and $H_2O_2$ consumption are analyzed. Furthermore, the $UV/H_2O_2/O_3$ process in conjunction with $O_3$ generator enables us to not only save the treatment time by 6 hours but also reduce $H_2O_2$ consumption by 30%.

본 연구에서는 고농도 무전해 니켈도금 폐액을 처리하기 위한 고도산화공정 기술을 개발하였다. 추출, 농축 공정을 이용한 니켈 금속 회수보다는 폐수를 방류수 수준으로 처리할 수 있는 기술 개발을 위하여 차아인산염과 아인산염을 침전이 용이한 인산염으로 효과적으로 전환시킬 수 있는 공정 개발에 초점을 맞추었다. 광화학적 방법인 $UV/H_2O_2$ 방식을 채택하여 COD, $PO_4-P$ 변화 효율 및 과산화수소의 소모량을 분석함으로써 고농도 무전해 니켈도금 폐액의 고도산화처리 특성을 평가하였다. 특히, $UV/H_2O_2/O_3$ 방식으로 오존산화법을 추가함으로써 과산화수소 사용량을 30% 가량 절감하고 처리시간을 약 6 h 단축시킬 수 있었다.
