摘要
以某园区生产企业排放的循环冷却水排污水为主生产废水处理回用工程为实例,介绍了废水的来源、回用工艺、主要处理构筑物参数及运行效果。采用“机加池+快滤池+臭氧接触氧化池+BAC滤池+超滤(UF)处理+反渗透(RO)过滤”的处理工艺,回用水主要用作工业企业循环水站补给水,回用水水质达到《石油化工污水再生利用设计规范》(SH 3173—2013)以及《工业循环冷却水处理设计规范》(GB/T 50050—2017)中再生水用于间冷开式循环冷却水系统补充水的水质指标要求。工程运行实践表明:该系统运行稳定、出水水质好,具有良好的经济效益、社会效益和环境效益。
Taking the wastewater treatment and reuse project of circulating water cooling water discharged by a production enterprise in a park as an example,the source of wastewater,reuse process,main treatment structure parameters and operation effect are introduced.The treatment process of machine added tank+rapid filter tank+ozone contact oxidation tank+BAC filter tank+ultrafiltration(UF)treatment+reverse osmosis(RO)filtration is adopted.The reclaimed water is mainly used as the make-up water for the circulating water station of industrial enterprises,and the quality of the reclaimed water meets the design code for petrochemical wastewater reuse(SH 3173—2013)and the design code for industrial circulating cooling water treatment(GB/T 50050—2017).The project operation practice shows that the system runs steadily and has high treatment efficiency,obtaining great economic social and environmental benfits.
