摘　　要：本文主要介绍循环排污水现状及存在问题,采用流化床结晶技术用于石油化工企业循环排污水预处理中,通过中试试验结果表明:该技术可将其硬度的去除率达80%以上,并考察得出出水水质的p H、电导率、硬度与进水基本一致,仅有效降低了系统出水硬度指标。该流化床结晶技术具有节省药剂投加量、占地面积小等优点。This paper mainly introduces the current situation and existing problems of circulating effluent. Fluidized bed crystallization technology is used in the pretreatment of circulating effluent in petrochemical enterprises. The pilot test results show that: The technology can remove more than 80 % of the hardness, and the p H, conductivity and hardness of the effluent water are basically the same as those of the influent water, which only effectively reduces the hardness index of the system effluent water. The fluidized bed crystallization technology has the advantages of saving the dosage of agent and small footprint.
