摘要
介绍了大连凌水河污水处理厂CAST工艺设计参数和工艺特点,实际运行中进出水水质情况及运行效果。分析了CAST工艺的进水方式、曝气量、污泥浓度等运行参数对污水处理效果的影响。凌水河污水处理厂的运行结果表明,CAST工艺对城市污水有较好的处理效果,出水指标稳定达到了《城镇污水处理厂污染物排放标准》(GB18918-2002)一级B标准。
Technological characteristics and design parameters of cyclic activated sludge technology（CAST） used in Dalian Lingshui river wastewater treatment plant were introduced as well as operating results,inlet and outlet water conditions in actual operation.Effects of wastewater distribution method,aeration rate and sludge concentration on treatment efficiency of wastewater were analyzed.The operation results show that CAST is effective to treat municipal sewage,outlet water indicators are stabilized,and reach to the first class of B standard of discharge standard of pollutants for municipal wastewater treatment plant（GB18918-2002）.
