摘要
印染废水排量大,有机物含量和色度高,组分复杂,水质变化范围大。在对印染废水进行最终处理时,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(水解)好氧联合处理较为合适;对易于生物降解的印染废水,可采用生物处理。色度的去除,一般以物理化学方法为主,对于规模大、处理技术水平高的工厂,则可采用电解、化学絮凝、臭氧氧化等工艺,对于小规模的工厂,可采用炉渣过滤。
Wastewater from dyehouse features large volume, high organic content, dark color and complex substances. In wastewater treatment, biological method is normally used for organic substances removal and biodegradable wastewater treatment, combination of anaerobic treatment and aerobic treatment is used for non-degradable wastewater treatment. Color removal is usually carried out by physicochemical methods, such as electrolysis, chemical flocculation and ozone oxidation in large-scale plants, and slag filtration in small-scale plants.
