摘　　要：为改善巢湖流域水质状况,使污水处理厂出水满足GB18918—2002《城镇污水处理厂污染物排放标准》中一级A标准,且达到ρ(CODCr)≤20mg/L、ρ(NH3-N)≤1.5mg/L、ρ(TP)≤0.3mg/L,设计采用A2/O-D型滤池-生态处理组合工艺。工程运行结果表明:在进水CODCr、NH3-N、TN、TP的平均质量浓度分别为83.22、14.53、20.80、2.03mg/L时,出水均值分别为14.98、0.38、7.71、0.15mg/L,去除率分别为82.0%、97.4%、62.9%、92.6%。介绍了该工程的设计参数及特点,分析了其运行成本、经济与环境效益,为高标准出水要求的乡镇污水处理厂设计提供一定参考。To improve the water quality of Chaohu basin, A2/O-D type filter-ecological treatment process was used to make the quliaty of the effluent water from sewage treatment plant meet the requirement of grade 1 level A of GB 18918-2002 Discharge Standard of Pollutants for Municipal Wastewater Treatment with the mass concentrations of CODCr, NH3-N and TP not above 20, 1.5 and 0.3 respectively. The operation result of the project showed that, when the average mass concentrations of CODCr, NH3-N, TN and TP in influent water were 83.22, 14.53, 20.80 and 2.03 mg/L respectively, the above indicators in effluent water were 14.89, 0.38, 7.71 and 0.15 mg/L respectively, the removal rates were 82.0%, 97.4%, 62.9% and 92.6% respectively. The design parameters and characteristics of the said engineering were introduced with the operation cost, economic and environmental benefit analyzed at the same time, which provided reference for the design of stringent specification town and village sewage treatment plants.
