针对太湖流域某地水厂常规过滤介质对微污染水源水中典型污染物去除效果不甚理想的情况,开展了碱式聚合氯化铝(PAC)改性滤料强化过滤试验研究.研究结果表明:PAC改性石英砂滤料对浊度、CODMn、UV254的去除效果明显优于未经改性的普通石英砂滤料,去除率分别提高了0.3%、12.4%、13.8%;同时,能强化对稳定性铁锰的过滤效果,在进水铁浓度为1.21 mg/L时,改性滤料对铁的去除率比普通石英砂滤料高9.1%.

Due to the shortage of conventional filteration process with the micro-pulluted source water in Taihu Lake, the enhanced filteration with PAC coated filter was tested. The result shows that the coated filter has more efficacy to removal of turbidity, CODMn and UV254 in the water, and the removal efficacy is promoted 0.3%, 12.4%, 13.8% respectively. The removal efficacy of stable iron and manganese can also be promoted simultaneously. When the iron concentration condition was 1.21 mg/L,...
