腔式地下渗滤系统运行参数研究

Study on the Operation Parameters of Chamber Underground Infiltration System

运行参数是腔式地下渗滤系统成功的关键要素之一。运行参数决定着系统的运行年限和对污水中污染物质的降解效果。为了获得使腔式地下渗滤系统处于最佳处理效果的运行参数,选取水力负荷、配水时间、湿干比三个运行参数为试验因子作为研究对象进行研究,以系统对污水中污染物质的去除率作为指标,通过分析得出各运行参数的最佳值为:水力负荷15 cm/d,配水时间8h,湿干比1:9。

Operation parameter was a key factor to parameters determined the system life and degradation the success of chamber underground infiltration system. Operation effect of pollutants in wastewater. To get to operation parameter which made chamber underground infiltration system be in the best treatment effect, three operation parameters such as hydraulic load, distribution water time and dry weight ratio were selected to the trial factor as research object to do study. And removal rate of sewage pollutants was used as an index in the system. The optimal level of various operation parameters were obtained by the analysis： hydraulic load 15cm/d, distribution water time 8h, and dry weight ratio 1 ： 9.
