直链烷基苯磺酸盐的广泛运用,使其成为环境中最常见的具有代表性的一类有机污染物,其环境行为与环境效应也受到普遍的关注。以生活污水中直链烷基苯磺酸盐为对象,研究了地下渗滤系统对其去除效果以及对其他污染物去除和基质微生物量的影响。结果表明：污水中直链烷基苯磺酸盐浓度在0.56~40 mg/L,地下渗滤系统对直链烷基苯磺酸盐的去除率达到90%以上；直链烷基苯磺酸盐去除率随着其浓度的增加而增加。随着直链烷基苯磺酸盐浓度的升高, COD、TN、TP和 IP的去除率下降,而 NH+4

Linear alkylbenzene sulfonates (LAS)is a kind of organic pollutants that is most familiar and representative as to its environmental behavior and effect.The removal of LAS was studied in the subsurface wastewater infiltration system.The results showed that subsurface wastewater infiltration system had strong purifying function to LAS and its removal rate more than 90% when LAS concentration was between 0.56 and 40 mg/L.The removal rate of LAS increases with the increase of the concentration of LAS.The removal rate of COD,TP and IP decreased with the increase of concentration of LAS,meanwhile,the removal rate of NH+4 N had few change.The amount of bacteria,fungi and actinomyces decreased with the increase of concentration of LAS.LAS had no influence on the amount of nitrifying bacteria.The amount of denitrifying bacteria increased firstly and decreased finally.
