摘　　要：为保护下游白洋淀地表水及地下水的水质,以高阳县印染废水为处理对象,对高阳污水处理厂的工艺和运行参数进行了优化和调试。采用混凝沉淀-水解酸化/曝气池-曝气生物滤池-活性砂滤为处理工艺,设计处理规模为12万m3/d,当进水的COD,SS,NH3-N和TP的质量浓度分别为669,424,8.83和6.03mg/L时,经该工艺处理后其最佳去除率分别为93.5%,98.8%,97.1%和96.2%,出水水质达到《城镇污水处理厂污染物排放标准》(GB 18918-2002)一级A标准,其运行成本仅为0.807元/m3。工程的建设和运营不仅改善了周围环境,而且促进了区域经济发展,工艺的设计和运行参数为印染废水处理行业提供了重要参考。In order to protect the quality of Baiyangdian surface and ground water,taking the printing and dyeing wastewater in Gaoyang County as the treatment subject, the process and operating parameters of Gaoyang Wastewater Treatment Plant are optimized and tested. The process of coagulation sedimentation-hydrolytic acidification with aeration tank-biological aerated fil-teractive sand filters is applied, and the designed treatment scale is 1. 2 × 10^5 m^3 /d. The influent is as following： COD is 669 mg/L, SS is 424 mg/L, NH3-N is 8 . 83 mg/L, and TP is 6 . 03 m g / L . After the process, the best removal rates of COD , SS, NH3-N and TP are 93. 5% ,98. 8 % ,97. 1% and 96. 2% , respectively. The various indexes of effluent water comply with stand-ard A of the first order in Pollutants Emission Standard of Urban Wastewater Treatment Plants （GB 18918-2002）, The processing cost is only 0. 807 yuan/m^3. As a result, the project construction and operation not only improve the environment, but also promote regional economic development. Process design and operating parameters provide important reference value for treatment of the printing and dyeing wastewater industry.
