Abstract:

Jar test demonstrates that the combined process of PASS and PACadsorption is effective forenhancing treatment of micro-pollutedrawwater. The turbidity, COD_Mn and UV₂₅₄ of the water sampleare reducedsignificant lyafter beingtreated. It is observedthat dosingsequenceof PACaffects thetreatment efficiency tosome extent. Soundenhancement for treatment couldbe achievedwhenPACandcoagulant are addedat thesame time. Theenhancing treatment mechanismisd iscussed throughUV, and GC/M Sanalyses.

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、COD_Mn、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。
