| 摘 要： | 本文考察了气升式环流反应器生化处理化纤废水的效果。结果表明：在16-28℃下，通气量为0．325m^3／h，水力停留时间为7、0h，pH值为8．5～9．0时，化纤废水COD降解速率最快，COD去除率可达93％以上。而且适当补加磷源（如COD和磷源质量比为200：1时）有利于化纤废水COD的降解。该反应器连续运行了30d，经处理后的水质COD和氨氮分别降低到100mg／L和10mg／L以下，达到了化纤类废水国家一级排放标准。

| Abstract: | The bio-chemical treatment of chemical fiber airlift type circulating reactor was studied. It was shown that ,under the conditions of air flow of 0.32m^3/h,HRT7.0 and pH 8.5 -9.0, the COD degradation speed of chemical fiber wastewater was the quickest. COD removal rate could reach to over 93%.In addition, properly adding phosphorus is advantageous to COD degradation in chemical fiber wastewater. The reactor operated continuously for 30d, the effluent COD and NH3-N lowered to below100 mg/L and 10mg/L respectively, reaching the national first class discharge standard of chemical fiber wastewater. |
