저가용 폐수오니 여과장치 개발에 관한 연구 A Study on the Development of Low Cost Sewage Sludge Filtration System
pp.545-551
As the pollution from waste marine emissions becomes serious, the government's regulations are becoming more stringent. In addition to sewage sludge, manure sludge and waste sludge were included in the prohibition of off-shore sewage treatment and the allowable standard value of pollutants for the water quality discharged by the companies was increased. The difficulties of the enterprises due to the increase of the wastewater treatment costs are increasing. In order to solve these problems, it is necessary to reduce wastewater treatment costs and the processing burden of the consigned waste processing companies by constructing wastewater pretreatment facilities of their own waste. Therefore, it is urgent to develop low cost wastewater pretreatment or treatment facilities and technologies to meet the situation of wastewater discharge companies. In this study, a low cost system has been developed for filtering sludge in the wastewater by modifying the structure of drum screen and adopting the impact separation method. Using this system, the procedure and cost for purification and subsequent retreatment of a highly concentrated wastewater can be significantly reduced.
