摘要
印染废水中有机物的去除一般以生物法为主;对难以生物降解的印染废水,采用厌氧-好氧联合处理较为合适;对易于生物降解的印染废水,可采用生物法处理,色度的去除,一般以物理化学方法为主。三级降解印染废水方法是目前的发展趋势,能保证在不增加成本的前提下,有效降低色度,使出水达标排放。
In the final treatment of dyeing wastewater, biological method is general the mainly method of organic removal. For the kind of hard to be biodegradation, adopt anaerobic-aerobic combined processing is relatively appropriate. For the color removal, it is general adopt physical and chemical methods. The current development trend of dyeing wastewater treatment is tertiary degradation, which can reduce the chromaticity effectively and reach the emission standard without any increase in the cost.
