摘　　要：中药提取物生产过程中产生大量的废水,成分复杂,有机物浓度高。采用新型高效厌氧池+改良型好氧(UCT)组合工艺处理此类废水,实际运行结果表明,该系统运行稳定,进水COD为15 000~25 000 mg/L时,COD平均去除率达98.8%,出水COD<100 mg/L,出水BOD_5、氨氮及总磷平均浓度分别为18.0、6.50、0.386 mg/L。各项出水指标均满足园区污水处理厂纳管标准。A lot of wastewater containing high strength and complicated organic pollutants was produced during the process of Chinese traditional medicine extraction. With regard to the wastewater quali- ty, the combination process including new anaerobic reactor and UCT was applied to treat the high strength organic wastewater from Chinese traditional medicine extraction process. The operation results showed that the influent and effluent COD were 15 000 -25 000 mg/L and 100 mg/L respectively, COD removal efficiency was up to 99% ; the effluent BOD5, ammonia nitrogen and total phosphorus were 18.0, 6.50 and 0. 386 mg/L respectively. The effluent quality could meet the influent standard of industrial park sewage centralized treatment plant.
