无锡某纺织厂染整废水处理工程设计摘要.doc

无锡某纺织厂染整废水处理工程设计摘要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 10000m 3 /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 1 COD Cr /mg/L 11 00 100 2 BOD 5 /mg/L 5 00 25 3 SS/mg/L 3 00 70 4 色度/倍 400 40 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: 废水格栅提升泵房水解酸化池 SBR 反应池混凝沉淀池出水集泥井污泥泵房污泥浓缩池污泥脱水污泥外运调节池关键词:印染废水; 水解酸化; SBR ;混凝沉淀。 W uxi Knitting Factory Wastewater Treatment Project Design Abstract The Knitting Factory isa set ofkni tting, dyeing and clothing in the one-stop production line associates. The wastewater generated from the bleaching and dyeing workshop machine bleaching and dyeing workshop. And printing and dyeing wastewater is an intractable industrial wastewater with anic pollutant content and deep color. As people increasingly high quality requirements on the environment, printing and dyeing wastewater discharge standards have been much more strict. Separate biochemical orphy s ic al -chemical treatment is difficult to meet emission requ ire ments for the high and the difficulty of handling the printing and dying wastewater. Domestic printing and dying wastewater treatment , the use of the means of the main biochemical methods, supplemented by the chemical method. The design of water i
