摘要
中山市某印染工业园区集中污水处理厂采用磁混凝沉淀工艺对MBR膜产水进行深度处理,建立了一套20000m3/d的处理系统,具有良好的深度处理效果,其中COD去除率大于24%,最高可达41%;SS去除率大于50%,最高可达64%;TP去除率大于72%,最高可达84%,出水水质稳定达到GB 4287—2012《纺织染整工业水污染物排放标准》限值要求。该系统直接运行成本为0.296元/t水,其中药剂成本为0.267元/t水,电耗成本为0.029元/t水,磁粉回用率高。该系统具有占地面积小、出水水质好且稳定、运行成本低、自动化程度高的优点。
A 20,000 m3/d treatment system for MBR membrane wastewater is set up in a central sewage treat-ment plant in a printing and dyeing industrial park in Zhongshan city,which has a good advanced treatment ef-fect.After wastewater treatment,the COD removal rate is higher than 24%and can reach up to 41%,the remov-al rate of SS is higher than 50%and can reach up to 64%,the TP removal rate is higher than 72%,up to 84%,and the effluent quality is stable and meets the limit requirements of GB 4287—2012“Emission Standard for Water Pollutants in Textile Dyeing and Finishing Industry”.The direct operating cost of the system is 0.296 RMB/t of water,of which the cost of chemicals is 0.267 RMB/t of water,the cost of electricity con-sumption is 0.029 RMB/t of water,and the magnetic particle reuse rate is high.This system has the advantag-es of small area,good and stable effluent quality,low operating cost and high degree of automation.
