【摘要】 以乐果微污染水源水为研究对象,对比研究了KMnO4与O3作为预氧化剂,石英砂、沸石与活性炭作为滤料的生物滤池对饮用水水源中乐果残留物的去除效果。实验结果表明,以石英砂、沸石和活性炭作为滤料,经高锰酸钾或臭氧预氧化处理后,乐果去除率较好,特别是沸石和活性炭的去除率达到了90%以上。臭氧处理效果比高锰酸钾好,处理率提高了10%以内。从去除率、经济性和易操作性方面考虑,高锰酸钾和沸石联用更适合中国农村供水的实际情况。更多还原

【Abstract】 The research subject was water source lightly contaminated by Rogor.A comparative analysis was also conducted,using potassium permanganate and ozone as pre-oxidizer,quartz sand,zeolite and activated carbon as filtering material,in order to determine the effectiveness of bio-filter to sanitize drinking water.The research demonstrated that Rogor was more effectively removed when using above mentioned filtering material,pre-oxidized with potassium permanganate or ozone,especially with zeolite and activated carbon,with a contaminant removal rate of over 90%.Ozone was also proved to be a better agent than potassium permanganate,with a efficiency rate of up to 10% higher.Considering removal rate,economic value and ease of operation,potassium permanganate and zeolite combo filtering technique was more appropriate for rural application under current condition.更多还原
