印染废水回用的连续微滤_反渗透技术_张云

印染废水回用的连续微滤/反渗透技术张云(江苏省水文水资源勘测局南通分局，江苏南通226006)摘要:采用连续微滤(CMF)+反渗透(RO)技术对印染废水进行深度处理，研究CMF+RO集成工艺的处理效果。试验结果表明，CMF+RO处理系统运行稳定，对CODCr、色度、浊度、电导率的去除率均达98%以上，RO出水水质优于自来水，各项水质指标均满足印染工艺回用水的要求。关键词:染整;废水处理;连续微滤;反渗透中图分类号:TS199文献标识码:B文章编号:1000－4017(2012)24－0030－03Continuousmicrofiltration/reverseosmosistechniqueforreuseofdyeingeffluentsZHANGYun(NantongSubstationoftheHydrologyandWaterResourcesInvestigationBureauofJiangsuProvince，Nantong226006，China)Abstract:Advancedtreatmentofdyeingwastewateriscarriedoutwithcontinuousmicrofiltration(CMF)andreverseosmosis(RO)com-binedprocess，anditseffectisstudied．TheresultsshowthatthesystemofthecombinedprocesswithCMFandROworkssmoothly，andcaneffectivelyremoveover98%ofthetotalCODCr，chromaticity，turbidityandconductivity．ThewaterqualityofROeffluentissuperiortothatoftapwater．Themainwaterqualityindexesofthetreatedwatercanmeetthedemandsofdyeingandprintingprocess．Keywords:dyeingandfinishing;wastewatertreatment;continuousmicrofiltration;reverseosmosic0前言纺织印染是江苏省的支柱产业，也是江苏省水资
