%X 中煤九鑫焦化有限责任公司现有电厂循环水、化产循环水及化产低温循环水3个循环水场,产生污水70 m3/h,为节水减排,采用"三法净水"专利技术与JR-EDR(新型频繁倒极电渗析)技术组合工艺对污水进行处理回用。与传统的混凝过滤技术相比,"三法净水"技术不仅能去除水中的浊度、悬浮物,而且能去除硬度、胶体、总磷、COD等,为后续JR-EDR脱盐设备提供较好的进水条件。JR-EDR脱盐工艺作为一种物理化学反应过程进行脱盐。组合工艺的联用有效提高循环水系统水质的同时减少了排污量。 There are three circulating water sources,which are power plant,chemical production workshops and low-temperature circulation process of chemical production in Jiuxin Coking Limited Liability Company.The sewage production is 70 m3/h.To save water and reduce discharge,three-step water purification technology and JR-EDR technology are adopted to treat coking circulation water.Compared with traditional gel filtration technology,the three-step water purification technology could remove turbidity,suspended matter,hardness,colloid,total phosphorus,COD and the like.The improvement of water quality lightens the burden on subsequent JR-EDR desalting equipments.The combination of these two technologies effectively improves water quality and reduces discharge quantity
