混凝气浮-水解酸化-接触氧化-混凝沉淀工艺处理染色废水

混凝气浮-水解酸化-接触氧化-混凝沉淀工艺处理染色废水混凝气浮-水解酸化-接触氧化-混凝沉淀工艺处理染色废水卢大群,王厚俊,何谨(泰州市环境监测中心站,江苏泰州225300)摘要:该处理工艺对悬浮物、胶体,色度具有极高的去除率。对该废水在投加混凝剂的基础上再投加少量的脱色剂,脱色效率可达90%以上。混凝气浮预处理后,消减了废水中的有机物,大大降低后续处理设施的负荷,提高了整套系统运行的稳定性。同时,减少了投资规模,降低了运行费用,获得了理想的处理效果。关键词:染色废水;混凝气浮;水解酸化;接触氧化;混凝沉淀中图分类号:X7文献标识码:B文章编号:1004-8642(2006)S2-0046-03收稿日期:2006-05-26作者简介:卢大群(1968-),女,江苏泰州人,大专,助理工程师,主要从事环境监测工作.TreatmentofDyeingWastewaterwithAirFlotation-HydrolysisAcidification-ContactOxidation-CoagulatingSedimentationProcessLUDa-qun,WANGHou-jun,HEJinAbstract:Akindofcombinedprocessconsistingairflotation-hydrolysisacidification-contactoxidation-coagulatingsedimentationwasappliedtotreatmentofdyeingwastewater,whichhashighremovalefficiencyofSS,colloidandchroma.Byusingseveraldecolourant,thedecolorizingratewasabove90%.Asmainlyorganiccompoundswereremovedinairflotationsegment,sotheloadoffollowingapparatuswasreduced,consumedlyandoperationstabilitywasimproved.Moreoverthescaleofinvestmentandrun-costweregreatlyreduced.Keywords:Dyeingwastewater;Airflot
