摘要
针对二级生化后的达标印染废水含盐量高、色度高等特点,采用CMF＋RO对其进行回用,回用率达70%,脱色率为100%,脱盐率为96%~98%,COD去除率为90%、产水硬度〈10 ppm,产水水质优于自来水,可直接或混合自来水用于高档布料染色。
The CMF＋RO process is taken to treat dyeing waste water after secondary biochemical treatment with high salinity and chromaticity.The recycling rate is about 70 %,the decolorization rate was 100 %,the desalination was about 96 %~98 %,the COD removal rate was about 90 %,and the hardness of treated water is less than 10 ppm,the quality of treated water is better than tap water,and can be used directly or mixed with tap water in high-grade fabric dyeing.
