无锡某纺织厂染整废水处理工程设计摘要

1、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1CO
