污水深度处理及回收利用的可行性分析

Possibility Analysis of Deep Treatment and Recovery of Produced Water

大庆炼化公司从单一化工污水深度处理及回收利用发展为炼油、化工、生活污水统一处理和回用于循环水,既充分利用了现有污水处理场的处理余量,同时由于生活污水中含有比例适当的微生物需要的营养物质,对炼油和化工污水起到补充和稀释作用。这种处理方法既降低了工业污水对污水处理场的冲击,又起到了稳定水质的作用。

The comprehensive treatment and recovery of wastewater produced from refinery, petrochemical factory and sanitary sewage are carried out in Daqing Petrochemical Company. This integrative method can reduce the compact of industrial wastewater on sewage disposal plant and keep the quality of recycle water. Some useful substances for microbes often exist in sanitary sewage and can dilute wastewater produced from petrochemical process and refinery.
