摘要 根据鹊山水库水低浊、微污染和高藻的水质特点,采用微砂强化混凝工艺对其进行处理,结果表明:微砂强化混凝的效果优于常规混凝,可使沉淀出水水质得到显著提高。当微砂、FeCl3及PAM的投量分别为1000、30、0.5mg/L时,沉淀出水浊度〈0.78NTU,色度〈2倍,对藻类、TOC、CODMn、UV254的去除率分别可达92.6%、85.6%、67.8%和68.8%以上,该方法为处理该水库水的工艺选择提供了泰者。 According to the reservoir water with low turbidity, micro-polluted and high algae content characteristics, the micro-sand enhanced coagulation process was presented. The experiment results show that the micro-sand coagulation process is more effective than the conventional coagulation process, and has the advantages of higher quality of sedimentation effluent. When the 1 g/L of micro-sand, 30 mg/L of FeC13 and 0.5 mg/L of PAM are added, the effluent turbidity is less than 0.78 NTU, the color degree is less than 2 degrees, and the removal rate of algae 〉 92.6%, TOC 〉 85.6% , CODMn 〉 67. 8%, UV254 〉68.8%. The experiment results can act as a reference for reservoir water treatment.
