  • 摘要: 以处理城市污水的中试规模Johannesburg工艺为对象,探讨不同配水比对预缺氧池的反硝化及Johannesburg工艺脱氮除磷效果的影响。在总HRT为12.86 h,预缺氧池HRT为0.6 h的条件下,当配水比分别为0%、10%、20%和30%时,预缺氧池硝酸盐去除率分别为37.67%、78.95%、87.62%和94.95%,对应的厌氧池磷酸盐浓度分别为8.72、19.37、16.1和12.99 mg/L。预缺氧池最佳配水比为10%,此时厌氧段释磷速率、好氧吸磷速率和缺氧吸磷速率分别为6.94、3.17和2.12 mg/(g MLSS·h),厌氧池中磷的最大浓度和污泥中的磷最大含量可达到19.37 mg/L和25.7 mg TP/g MLSS。出水COD、NH3-N、TN和TP等各项水质指标有80%以上的概率达到《城镇污水处理厂污染物排放标准(GB18918-2002)》一级A标准。
    Abstract: A pilot scale reactor was employed to study the effects of water distribution ratio on the performance of Johannesburg process.The performance of pre-dentrification tank as well as the removal efficiency of nitrogen and phosphorus were investigated.The HRT of pre-denitrification tank was 0.6 h when the total HRT was 12.86 h.The concentrations of phosphorus in the corresponding anaerobic tank were 8.72,19.37,16.10 and 12.99 mg/L while the nitrogen removal rates of the pre-denitrification tank were 37.67%,78.95%,87.62% and 94.95% with the distributing water rates of 0%,10%,20% and 30%,respectively.The results indicate that in the four selective water distribution ratios (e.g.0%,10%,20% and 30%),10% is the best rate for removing phosphorus.At this rate,the anaerobic phosphorus release rate is 6.94 mg/(g MLSS·h);the aerobic phosphorus uptake rate is 3.17 mg/(g MLSS·h);the anoxic phosphorus uptake rate is 2.12 mg/(g MLSS·h).At the same time,the phosphorus concentration in the anaerobic tank (19.37 mg/L) and the maximum phosphorus content in residual sludge (25.7 mg TP/g MLSS) are both observed.In addition,the concentration of the pollutants in effluent,including COD,NH3-N,TN and TP,can meet the first grade A discharge standard of pollutants in municipal wastewater treatment plant (GB18918-2002)more than 80% probability.
