摘　　要：国家“863”计划-“南方地区安全饮用水保障技术”对活性炭出水的浊度要求是0.1NTU,为达到这一要求,通过中试研究,考察了活性炭滤柱对浊度的去除效果,提出了强化活性炭滤池浊度的新工艺。结果表明,采用聚合氯化铝(PAC)强化过滤,可以保持活性炭滤池较高的浊度去除效率,保障浊度完全达到0.1NTU的出水标准。The turbidity criterion for the product water ofa WTP according to the State Project “863” on the safeguard technology of drinking water in southern areas in China is 0.1NTU. The turbidity removal in the activated carbon filter was analyzed in the pilot-scale test and an innovative technology to improve the turbidity removal in biologically activated carbon （BAC） filter was put forward in order to meet the criterion. It was shown from the results that the turbidity removal in the BAC filter could be kept at a high level by the addition of polymerized aluminum chloride （PAC） with the filtrate turbidity equal to or less than 0.1NTU.
