摘要
采用粗格栅+膜格栅+调节池+浮沉池+两级水解酸化-接触氧化-沉淀池+BAF组合工艺处理某中药厂废水,介绍了该工艺的技术特点,并给出了主要构筑物的技术参数,分析了运行过程出现的问题及解决对策。工程运行结果表明,该工艺可有效去除废水中污染物,出水水质稳定达到《中药类制药工业水污染物排放标准》(GB 21906—2008)。
A combined process of coarse grille, membrane grille, regulating tank, floating sedimentation tank , two-stage hydrolysis acidification/contact oxidation/sedimentation tank and BAF was selected to treat the wastewater from a traditional Chinese medicine plant. The technical characteristics of this process were introduced, and the technical parameters of main structures were given. The problems and the corresponding solutions in the operational process were provided. The engineering operation results showed that the process could effectively remove pollutants from the wastewater, and the effluent quality could reach the Discharge Standard of Water Pollutants for Pharmaceutical Industry Chinese Traditional Medicine Category ( GB 21906 - 2008) stably.
