高浓度有机废水的好氧生物法-吸附法协同处理

摘要

High concentration organic wastewater was treated by aerobic biotechnology-adsorption method; and the factors affecting the removal rate of CODcr and chromaticity were studied. The removal rates of CODCr were 94.7% when wastewater was treated using aerobic biotechnology method. When the wastewater which has been firstly treated using aerobic biotechnology method was retreated using adsorption method, the removal rate of CODcr and chromaticity was 81.3% and 93.4% respectively. After treated using aerobic biotechnology-adsorption method, the concentration of C0Dcr in wastewater decreased from 4 340 mg/L to 43mg/L, and the total C0Dcr removal rate was 99.0%.%采用好氧生物法-吸附法协同处理高浓度有机废水,探讨了各种因素对废水CODCr和色度去除率的影响.结果表明,废水经好氧生物法处理,CODCr的去除率为94.7％;好氧生物法处理后的废水经吸附法处理,CODCr和色度去除率分别为81.3％和93.4％;经好氧生物法-吸附法协同处理后,废水CODCr由4 340 mg/L降至43 mg/L,CODCr的去除率为99.0％,废水处理效果良好.
