摘要
采用超声波／改性粘土工艺去除常州市淹城古遗迹人工水体中的蓝藻。结果表明，该工艺运行费用低，操作简单，无二次污染。在原水浊度、CODMn、TN、TP及叶绿素a分别为24NTU、9．26mg／L、1．897mg／L、0．169mg／L、22．76μg／L的条件下，对浊度、CODMn、TN、TP及叶绿素a的去除率分别为85．42％、46．65％、52．66％、85．8％、84．58％，处理后的水质达到了《地表水环境质量标准》的Ⅱ～Ⅲ类标准。
The ultrasonic/modified clay process was used to remove blue algae from the artificial waters of the ancient Yancheng city site located in Changzhou City. The results indicate that this process has low operation cost, simple operation and no secondary pollution. When the raw water turbidity, CODMn, TN, TP and chlorophyll-a are 24 NTU, 9.26 rag/L, 1. 897 mg/L, 0. 169 mg/L and 22.76 μg/L, the removal efficiencies of turbidity, CODMn, TN, TP and chlorophyll-a are 85.42%, 46.65%, 52.66%, 85.8% and 84.58% respectively. The treated water quality reaches the Ⅱ -Ⅲ criteria specified in the Environmental Quality Standards for Surface Water.
