Abstract:
The wastewater discharged from cosmetics industry is characterized by complicated components,high surfactant concentration and toxicity. The combined air flotation-hydrolytic acidification-aerobic process has been used for its treatment. The practice proves that when the influent COD is about 9 000 mg/L,and the system remains relatively stable condition,the effluent water quality meets the requirements for the first level standard specified in the Integrated Wastewater Discharge Standard(GB 8978-1996).

摘要：
化妆品企业排放的生产废水成分复杂、表面活性剂浓度较高且有一定毒性，针对该类高浓度有机废水，采用气浮-水解酸化-好氧组合工艺进行处理，工程实践表明：当进水COD为9000 mg/L左右、系统维持相对稳定的情况下，出水水质达到《污水综合排放标准》（GB 8978-1996）的一级标准要求。
