【摘要】 为了研究了人工快滤系统对生活污水中LAS的去除效果。运用试验的方法对其进行研究,试验结果表明人工快滤系统对LAS具有较强的净化功能;在小于100mg/L范围内,人工快滤系统对LAS的去除率达到94%以上。LAS的去除率随着进水中LAS的质量浓度和土层深度的增加而增加;以去除LAS为目的的人工快速渗滤系统,适宜的土层深度为40~100cm。但对于LAS的去除机理需要进一步深入研究。更多还原

【Abstract】 The removal of LAS in the sewage was researched in the Artifical Rapid Infiltration Land Treatment System(ARI).It is showed that ARI has strong purifying function towards LAS,and the removal rate of LAS is more than 94% when the concentration of LAS in the sewage is less than 100mg/L.The removal rate of LAS increases with the increase of the concentration of LAS in the sewage and the thickness of soil-layer,meanwhile,the 40~100 cm depth of soil in the ARI is feasible for the removal of LAS.However,the mechanism of the removal of LAS need to be further researched in the ARI.更多还原
