摘要
本文提出了一种在上向流厌氧污泥过滤反应器及好氧接触氧化反应器内投加固定化脱色菌处理山西针织印染厂印染废水的新工艺。其结果提高了处理效率,改善了出水水质,化学耗氧量总去除率达92%,色度总去除率为90%以上。
This paper suggests a new technology of addingdecolourization-bac- teria into the upflow anaerobic sludge filter and aerobic contact-oxida- tion reactor to treat dyeing wastewater.The wastewater used in the study was obtained from Shan Xi Knitting Mill.The result showed that the efficiency of the treatment was improved with more than92% removal of COD and 90% removal of color.
