【摘要】 根据对江苏某纺织染整有限公司排放的纺织染整废水的水质污染情况分析,确定采用水解酸化-好氧接触氧化-生物滤池处理工艺。经过3个多月的调试运行,在进水COD_Cr为713⁹12 mg/L,BOD₅为261³52mg/L,SS为109¹83 mg/L,色度为200³50倍,NH₃-N为20²5 mg/L条件下,出水完全达到GB 4287-2012《纺织染整工业水污染物排放标准》中的排放要求。更多还原

【Abstract】 According to the analysis of the water pollution situation of textile dyeing and finishing wastewater discharged from a textile dyeing and finishing Co., Ltd., in Jiangsu, the treatment process of hydrolytic acidification aerobic contact oxidation biological filter was choose. After debugging and running for more than three months, the effluent completely reached the requirements of the textile dyeing and finishing industry water pollutants discharge standard（GB 4287-2012） when it was treated in the following conditions: influent COD_Cr 713⁹12 mg/L, BOD₅ 261³52 mg/L, SS 109¹83 mg/L, chroma 200³50 times, NH₃-N 20²5 mg/L.更多还原
