印染废水特点及其深度处理回用技术

Characteristics of Dyeing Wastewater and Deep Treatment Technology for Reuse

印染废水水量大、有机污染物含量高、色度深、碱性大、可生化性较差,属于难处理的工业废水。随着排放标准的日趋严格和水资源的不断短缺,印染废水深度处理和回用的问题越来越引起了人们的重视。通过对目前常用的印染废水深度处理及回用方法技术的比较,建议印染废水深度处理及回用应该将各种方法有机结合起来,充分发挥各种技术的优点和特色,才能高效、经济的达到回用目的。

The dyeing wastewater is a kind of intractable wastewater because its high organic pollutant content,chromaticity,alkalescency and feeble biochemistry character.The problem of dyeing wastewater deeply treatment and reuse attracts more and more people＇s attention with the standard strictly day by day and the increasing shortage of water.The deep treatment technology for reuse of dyeing wastewater was compared to put suggestion that methods must be combined to deeply treat and reuse dyeing wastewater and it will be high effect and economical by played their advantages and characteristics.
