以漓江源水为研究对象,当进水 CODMn的质量浓度为4~7 mg/L 时,比较不同工艺处理效果.进行模拟水厂的混凝沉淀实验,找出对 CODMn 去除效果较佳的条件.结果表明:在适宜的 Fenton试剂投加量下,并不能使 CODMn的出水浓度达标;粉末活性炭虽能有效吸附有机微污染物,但单独采用粉末活性炭的相对成本较高;比较不同联合工艺的处理效果发现,经粉末活性炭-Fenton-聚合氯化铝联合工艺处理后,CODMn出水达到标准要求.

Different processes for treatment of micro -polluted source water of the Lijiang River were compared when CODMn in input water was between 4 mg /L and 7 mg/L.Through simulation of coagulation and sedimentation in a water treatment plant, we determined the optimal conditions for removal of COD Mn .The results show that an appropriate dosage of Fenton ’ s reagent cannot make the effluent concentration of COD Mn meet the standards. Although powdered activated carbon can effectively adsorb organic micro -pollutants, there is a relatively high cost of using it alone.Through comparison of treatment effects of different joint processes , we found that with the powdered activated carbon-Fenton-polyaluminium chloride combined process treatment , the effluent of COD Mn could meet the standards.
