【摘要】 烧杯试验结果表明,聚硅硫酸铝(PASS)与粉末活性炭(PAC)联用对微污染水源水具有明显的强化处理效果,对浊度、CODMn、UV254均有较好的去除效果。但PAC的投加顺序对处理效果有一定影响,混凝剂与PAC同时投加可取得很好的强化处理效果。通过紫外、色谱-质谱(GC/MS)的分析,探讨了强化处理作用机理。更多还原

【Abstract】 Jar test demonstrates that the combined process of PASS and PAC adsorption is effective for enhancing treatment of micro-polluted raw water. The turbidity,CODMn and UV254 of the water sample are reduced significantly after being treated. It is observed that dosing sequence of PAC affects the treatment efficiency to some extent. Sound enhancement for treatment could be achieved when PAC and coagulant are added at the same time. The enhancing treatment mechanism is discussed through UV, and GC/MS analyses.更多还原
