摘要
[目的]研究倾斜土槽装置适宜的污水流量负荷。[方法]以5层倾斜土槽组合装置填充蜂窝煤渣和砂壤土,采用连续进水方式对人工配制的生活污水进行3种不同污水流量（100、200和300 L/d）对污染物指标去除效果的试验研究。[结果]3种污水流量处理对BOD5、COD、TP、TN等水质指标的平均去除率差异均不显著,但以100 L/d污水流量处理下污染物的去除率相对较大;倾斜土槽装置对BOD5、COD的去除率大都在87.8%~90.2%,对TP的去除率在98.4%~98.7%,TN的去除率也在72.0%~74.5%范围内。[结论]不同污水流量下倾斜土槽装置对生活污水的净化效果良好。
[Objective]The research aimed to study suitable flux load of wastewater of Slanted-Soil-Chambers.[Method]The effects of 3 kinds of different wastewater fluxes（100 L/d,200 L/d and 300 L/d） on removal rates of contaminant indices were studied by using five layers Slanted-Soil-Chambers with honeycomb cinder and sandy loam soil to treat domestic wastewater prepared artificially,by way of continuously influent.[Result]The results showed that the differences of the mean removal rates of BOD5,COD,TP,TN between these 3 flux treatments weren＇t all significant,but the contaminant index removal rate of 100 L/d treatment is a little bigger than others.The removal rates of BOD5,COD were between 87.8% and 90.2%,that of TP was between 98.4% and 98.7%,and that of TN was between 72.0 % and 74.5% in this experiment.[Conclusion]The purification efficiencies of domestic wastewater under the 3 kinds of different wastewater flux by using the Slanted-Soil-Chambers were well.
