| 摘 要： | 采用滤布滤池对南方某城市污水处理厂二级出水进行强化处理中试研究，以达到中水回用的目的。实验选用氯化铁(FeCl3)、聚合氯化铝铁（PAFC）和聚合氯化铝（PAC）作为强化滤布滤池除磷效果的混凝剂。当不投加混凝剂时，滤布滤池对TP和COD的平均去除率为28.76%和8%，其中TP的去除效果受进水水质影响较大；当投加氯化铁、聚合氯化铝铁与聚合氯化铝强化滤布滤池时，滤布滤池对TP的平均去除率分别为63.58%、60.13%和66.94%，TP去除效果受进水水质影响较小；对SS的平均去除率分别为70.7%、64.3%和49.1%；对COD平均去除率分别为17.7%、26.3%和27.7%。滤布滤池对TN和NH3-N去除效果不稳定。

| Abstract: | Cloth media filter was applied in the treatment of the effluent of a municipal wastewater plant through pilot scale test for water reuse.Ferric chloride(FeCl3),PAFC and polyaluminum chloride(PAC) were employed as coagulants respectively in the test.The average removal efficiency of TP and COD was 28.76% and 8% after cloth media filter without coagulation,and TP removal was influenced by the influent water quality.However,precoagulation with coagulants of ferric chloride,PAFC,PAC,the average removal efficien... |
