| 中文摘要: |
| 针对印染行业染整废水特点，采用了混凝沉淀、水解酸化和接触氧化工艺进行处理，在预处理阶段，采用絮凝剂FeSO4，当其投加浓度为500mg/L时，其对CODcr和色度的去除率分别达到31%和43%，同时增加了污水的B/C比。最终调试运行结果表明，在进水CODcr、BOD5、SS的质量浓度为1031、317、325mg/L，色度为313的条件下，去除率都能达到84%以上，出水指标均达到纺织染整工业水污染物排放标准。 |

| According to the characteristics of dyeing and finishing wastewater of printing and dyeing industry，the processes of coagulation precipitation, hydrolytic acidification and contact oxidation process were used. In the pre-processing stage, FeSO4 as flocculating agent, and dosing concentration at 500mg/L, its removal rate of CODcr and chroma can reach 31% and 43% respectively, meanwhile, the B / C ratio of sewage was also increasing. The final results show that the removal rate reach 84% under the influent concentration of CODcr at 1031 mg/L, BOD5 at 317 mg/L, SS at 325 mg/L, and chroma at 313. The effluent indexes meet the discharge standards of water pollutants for dyeing and finishing of textile industry |
