摘要
采用投加粉末活性碳方法处理白石水库微污染水。静态试验采用接触混凝、静沉,现场动态试验采用接触混凝、沉淀、过滤工艺。试验结果表明,投加粉末活性碳、聚合氯化铝和聚丙烯酰胺,可有效降低CODMn、浊度和色度。粉末活性炭投量、接触时间及粒度,对净水效果均有显著影响。相关最佳工艺条件为:活性炭投量20 mg/L,接触时间30 min,粒度0.074～0.147 mm。
Micro-polluted reservoir water was treated with powder activated carbon （PAC） . The experiment consisted of jar test and site dynamic test, the later included contact coagulation, sedimentation and filtration. The test results indicate that CODM, ,turbidity and chromaticity of micro-polluted water can effectively be reduced with PAC, aluminium polychlorid and polyacrylamide. Dosage and size of powder activated carbon, contact time have effects treatment result. The best process conditions are as follows： powder activated carbon dosage is 20 mg/L, contact time is 30 min , and size of PAC is 0.074-0.147 mm.
