| 摘 要： | 构建了3套以5%炉渣+95%草甸棕壤为基质的地下渗滤系统室内模拟试验装置,在水力负荷为0.1m3/(m2·d)条件下进行了生活污水处理试验.结果表明,当分流位置位于系统内110cm处,分流比为1:1时,可提高地下渗滤对总氮的去除效率,总氮的去除率由59.37%提高至68.41%,且对COD和总磷的去除效果没有影响. |

| Abstract: | The reason of low removal efficiency of total nitrogen in vertical infiltration of subsurface wastewater infiltration system(SWIS) is deficiency of carbon.Three pilot SWISs filled with the same mixed matrix of 5% slag and 95% brown soil were constructed in the laboratory.The experiment results showed that shunt distributing wastewater could significantly improve total nitrogen removal and the average removal rates of total nitrogen increased from 59.37%(without taking distributary measures) to 68.41%,and it... |
