摘　　要：采用混癌乏／厌氧／好氧／一体化臭氧曝气生物滤池／上流式曝气生物滤池组合工艺处理某制革厂废水，在进水量为50～80m^3／d的条件下，出水COD、氨氮和总铬含量可分别控制在100、10、0．3mg／L以下，完全达到该厂回用和排放标准。在不考虑人工及折旧费的情况下，运行成本仅为8．78元／m^3，具有良好的经济效益和环境效益。A combined process of coagulation, A/O, integrated ozone/BAF and up-flow BAF was applied to treat the wastewater from a tannery in Guangdong Province. With an influent of 50 to 80 m3/d, the effluent concentrations of COD, ammonia nitrogen and total chromium could be controlled at less than 100 mg/L, 10 mg/L and 0. 3 mg/L respectively, which met the reuse or discharge standards. The treatment cost was only 8.78 yuan/m3 without counting labor and depreciation costs. Great economic and en- vironmental benefits were gained .
