【摘要】 通过中试试验考察了高锰酸盐复合药剂预氧化与活性炭—砂滤池组合工艺处理富营养化水体的效能。与常规给水处理工艺的对比试验结果表明,投加质量浓度为1.5￣2.0 mg/L的高锰酸盐预氧化,并用活性炭-砂滤池代替原有的石英砂滤池,能有效地提高混凝与过滤工艺的综合除污染效能,该组合工艺对有机物、藻类、氨氮和亚硝酸盐氮的去除率可分别达到62.4%、99.5%、66.2%和65.9%,出水无明显嗅味。更多还原

【Abstract】 Compared with conventional drinking water treatment,the pilot studies of permanganate composite chemical(PPC) preoxidation and granular activated carbon-sand filter technique have been conducted on treating eutrophic raw water.The results show that both the preoxidation with a little dose of PPC(1.5-2.0 mg/L) and GAC-sand filter have obviously positive effects on improving traditional water treatment process.The combined process has higher efficiency in removing CODMn,algae,NH3-N,NO2——N with removal rates of 62.4%,99.5%,66.2%,65.9% respectively and the effluent odor level is decreased to detection limit.更多还原
