摘要：
江西某纺织企业采用初沉+水解酸化+CASS+混凝沉淀吸附+过滤组合工艺处理纺织工业印染废水，处理水量为8 000 m3/d。调试运行结果表明，当进水COD、BOD5、SS分别为2 000、450、300 mg/L，色度为800倍时，出水COD、BOD5、SS分别为54、10、30 mg/L，色度为30倍，平均COD、BOD5、SS和色度去除率分别为97.3%、97.8%、90.0%和96.3%，出水水质稳定，达到《纺织染整工业水污染物排放标准》（GB 4287—2012）中新建企业水污染物排放限值的要求。

Abstract:
The combined process,primary settling/hydrolytic acidification/CASS/coagulation sedimentation/filtration, has been used for treating the printing and dyeing wastewater in a textile enterprise,Jiangxi Province. The amount of wastewater treated a day is 8 000 m3. The results show that the COD,BOD5,SS and chroma of the effluent are 54,10,30 mg/L and 30 times,respectively,and the removing rates of COD,BOD5,SS,and chroma are 97.3%,97.8%,90.0% and 96.3%,respectively,when the COD,BOD5,SS,and chroma of the influent are 2 000,450,300 mg/L and 800 times,respectively. The quality of the final effluent is stable,and can meet the requirements for the discharge standard of water pollutants of new enterprise for dyeing and finishing of textile Industry(GB 4287—2012).
