Abstract:

Advanced treatment of secondary urban sewage by DynaSand continuous filter on wastewater reuse has been studied in a pilot test. The result indicatesthat the equipment is feasible technically, and the effluent water quantity is steady, and fulfills the Water Standard for Urban Water consumption (Exposure draft 2002). And the polymer selection and the filtrate result of the filter have been analyzed.

Key words: filter, continuous filter, regenerated water reuse

摘要：

采用DynaSand活性砂过滤器对城市污水处理厂二沉池出水进行深度处理中试试验，运行结果表明该装置用于市政中水回用是可行的，其出水水质稳定，各项指标优于《城市杂用水水质标准》2002年征求意见稿的要求。并对絮凝剂的选择和过滤器的过滤效果做了简要分析。
