Abstract

This study was focused on the treatment of thickened sewage sludge. General bacteria and E. coli were disinfected over 99％ and organic compounds were decomposed after irradiation. It was suggested that this process can be an alternative for digestion Process. The moisture content in sludge was decreased over 10％ (w/w) and the coagulation of sludge particles was enhanced by irradiation at the dose of 15 kGy and addition of sea waste resource (star-fish) as a dewatering aid.

본 연구는 하수처리장에서 발생되는 농축슬러지의 처리방법에 대해 진행하였다. 방사선을 15 kGy 조사하였을 때 농축슬러지에 존재하는 일반세균 및 대장균을 99% 이상 제거, 유기물 분해등 소화조에서 일어나는 공정을 대체 할 수 있다. 폐수산자원인 불가사리를 가공하여 제조한 물리개량제를 첨가하여 응집공정의 효율을 높이고 아울러 함수율 10% 이상의 저감효과를 얻을 수 있다.
