纺织染整废水的处理技术研究
摘要:今年来随着染整废水水质的变化,可生化性下降,染整废水的处理受到人们的高度重视。本文主要论述了染整废水去除色度、提高可生化性、脱氮除磷的方法。
Absteact: In recent years, with the change of water quality of dyeing and finishing wastewater, the biodegradability has decreased, and the treatment of dyeing and finishing wastewater has been highly valued by people. This people mainly discusses the methods of removing chroma, improving biodegradability, removing nitrogen and removing phosphorus from dyeing and finishing wastewater.

一、前言
纺织染整行业排放的印染废水是我国工业系统中重点污染源之一,据国家环保总局统计,印染行业排放的印染废水总量位于全国各工业部门排放的总量第五名[1]。纺织染整废水水量大、有机物浓度高、成分复杂、可生化性差、pH值高、色度深、碱性大,是污染负荷较大的行业。
