无锡某纺织厂染整废水处理工程设计摘要 4页

精品文档你我共享无锡某纺织厂染整废水处理工程设计该厂属大中型棉纺织印染企业，生产棉布，粘棉布，的确凉布，绒布等纺织产品。主要有漂染废水，印花废水，染色废水以及少量生活污水，废水水量大，水质成分复杂。而印染废水是一种难处理的工业废水，具有有机污染物含量高、色度深等特点。随着人们对环境质量要求越来越高，印染废水排放标准也越来越严。对于高及中难度处理的印染废水，单独的生化或者物化处理难以达到排放要求。目前国内的印染废水处理多采用以生化法为主，物化法为辅的手段。本次设计水量为10000m3/d，出水执行国家《纺织染整工业水污染物排放标准》一级标准。进出水水质见下表。表1进出水水质序号项目进水水质出水水质1CODcr/mg/L11001002BOD5/mg/L500253SS/mg/L300704色度/倍40040本工程方案设计依据有关环境保护在污水中的要求，采用水解酸化-SBR-混凝沉淀工艺处理印染废水，工艺流程如下:关键词：印染废水；水解酸化；SBR；混凝沉淀WuxiKnittingFactoryWastewaterTreatmentProjectDesignAbstractTheKnittingFactoryisasetofknitting,dyeingandclothingintheone-stopproductionlineassociates.Thewastewatergeneratedfromthebleachinganddyeingworkshopmachinebleachinganddyeingworkshop.Andprintinganddyeingwastewaterisanintractableindustrialwastewaterwithhighorganicpollutantcontentanddeepcolor.Aspeopleincreasinglyhighqualityrequirementsontheenvironment,printinganddyeingwastewaterdischargestandardshavebeenmuchAAAAAAn精品文档你我共享morestrict.Separatebiochemicalorphysical-chemicaltreatmentisdifficulttomeetemissionrequirementsforthehighandthedifficultyofhandlingtheprintinganddyingwastewater.Domesticprintinganddyingwastewatertreatment,theuseofthemeansofthemainbiochemicalmethods,supplementedbythechemicalmethod.3Thedesignofwateris10000m/d,Watertheimplementationofthenational“Dischargestandardofwaterpollutantsfordyeingandfinishingoftextileindustryfirststandard.Andoutofwaterasfollows.Table-1accesstowaterSerialnumberItemRawwaterqualityEmissionqualityOneCODcr/mg/L1100100TwoBOD5/mg/L50025ThreeSS/mg/L30070FourColority/Times40040Thedesignofthisprojectisinaccordaneewithrequirementsoftheenvironmentalprotectioninthewastewater.ItusesthehydrolyticacidificationSBRcoagulationsedimentationprocesstodealwiththewastewaterintextileprinting.Weselectthefollowingprocess:KEYWORDS:textileprintinganddyeingwastewater;hydrolyticacidification;SBR;coagulation.AAAAAAn精品文档你我共享沁园春•雪北国风光，千里冰封，万里雪飘。望长城内外，惟余莽莽；大河上下，顿失滔滔。山舞银蛇，原驰蜡象，欲与天公试比高。须晴日，看红装素裹，分外妖娆。江山如此多娇，引无数英雄竞折腰。惜秦皇汉武，略输文采；唐宗宋祖，稍逊风骚。AAAAAAn精品文档你我共享只识弯还看今一代天骄，成吉思汗,弓射大雕。俱往矣，数风流人物,”■克AAAAAA
