| 摘 要： | 在4～13℃低温环境中,Fe∶C=10∶1、pH=1.5空气搅拌条件下,Fe-C微电解对高浓度焦化废水COD的去除率为19.7％,B/C值从0.236提高到0.571.未加稀释水的条件下,Fe-C预处理后焦化废水厌氧COD去除率与常规补加稀释水的效果相当,静态自然消解速率为123.1 mg/L·d.处理后的焦化废水CO...

| Abstract: | In low temperature environment of 4～13 ℃ with iron-carbon microelectrolysis,COD removal efficiency of coking wastewater can reach 19.7% at Fe:C of 10:1 and pH 1.5.Biodegradability of wastewater was improved evidently from 0.236 to 0.571 and good conditions for following biotreatment were created.Results of the anaerobic treatment of pretreatment with Fe-C was the same with that replenish the dilution water,with natural degradation rate as 123.1 mg/L·d in low temperature environment.COD removal rate of 58.55% was beyond the normal activated sludge 54.5 mg/L in aerobic stage.With controlling the performance standard and concentration of Fe3+,the method of using Fe-C to combine with biochemical treatment will be an environmental friendly treatment process to deal with coking wastewater. |
