中成药制药废水成分复杂、有机物含量高、毒性大、色度深、含盐量高且可生化性差,采用IC厌氧工艺加生物接触氧化加絮凝沉淀工艺处理某中成药制药厂生产废水,使出水水质达污水综合排放标准(GB 8978-1996)一级标准,运行结果表明,COD、NH3-N、SS、色度平均去除率分别达99.25%、89%、88%、99%,采用该工艺处理中成药生产废水,可满足中成药制药废水水量、水质波动大的要求,在技术和经济上可行。
The traditional Chinese medicine pharmaceutical wastewater has complicated composition, high organic content, high toxicity, deep chroma, high salt content and poor biodegradability. An IC anaerobic process and biological contact oxidation plus flocculation sedimentation process are used to treat the waste water from a proprietary Chinese medicine factory The effluent quality reached the first grade standard of Integrated Wastewater Discharge Standard (GB 8978-1996). The operation results showed that the average removal rates of COD, NH3-N, SS and color were 99.25%, 89%, 88% and 99% Processing of proprietary Chinese medicine production wastewater, pharmaceutical wastewater can meet the traditional Chinese medicine, water quality requirements of large fluctuations in the technical and economic feasibility.
