摘要
扬州市六圩污水处理厂在一、二期工程中分别采用了活性砂滤和高密度沉淀池+转盘过滤器深度处理工艺,以保证出水达标排放。根据实际运行实践,总结了两种深度处理工艺在建设成本、运行成本、抗冲击负荷、运行维护、脱氮除磷、达标排放等方面的优缺点,并针对南方城市污水处理厂深度处理工艺的选择提出了建议。
The advanced treatment processes of activated sand filtration and high-density sedimen- tation tank with rotary disc filter were respectively applied in the phase I and phase 11 projects of Yang- zhou Liuwei WWTP to ensure the effluent quality to meet the discharge standard. According to the practi- cal operation experience, the advantages and disadvantages of two types of advanced treatment processes were summarized in terms of construction cost, operation cost, resistance to impact load, maintenance, nitrogen and phosphorus removal and up-to-standard discharge. Suggestions for selecting the advanced treatment process in south cities were made.
