摘　　要：针对安徽某聚苯乙烯化工厂的聚苯乙烯生产废水含磷、废水浓度较高、可生化性差等难点,先采用“混凝沉淀法”预处理工艺废水,有效除磷,再与其他废水合并后,通过“水解酸化+活性好氧污泥+沉淀”工艺处理,最终出水化学需氧量(Chemical Oxygen Demand,COD)、总磷等污染物稳定低于当地接管标准。该工程设计的投资费用及运行费用达到企业预期。In response to the difficulties of phosphorus content,high wastewater concentration,and poor biodegradability in the polystyrene production wastewater of a polystyrene chemical plant in Anhui Province,the"coagulation precipitation method"isfirst used topretreat the wastewater,effectively removing phosphorus.Then,itis combined with other wastewater and treated through the"hydrolysis acidification+active aerobic pollution+precipitation"process.Finally,the effluent Chemical Oxygen Demand(COD),total phosphorus and other pollutants remain stable below the local takeover standards.The investment and operating costs of the project design meet the expectations of the enterprise.
