| 摘 要： | 文章运用人工土柱模拟的方法来研究LAS对人工快滤系统去除TP的影响。研究结果表明,随着污水中LAS浓度(≤100mg/L)的增加,人工快滤系统对TP的去除率表现为逐渐下降。TP的去除率大小为处理Ⅰ>处理Ⅱ>处理Ⅲ>处理Ⅳ。在延长干化时间条件下,TP的去除率增大,并且LAS浓度越大效果越明显。LAS对人工快滤系统中TP的去除有着显著的影响;但合理地控制工艺参数能够实现LAS和TP的有效去除。

| Abstract: | Artificial soil-column simulation was used to study the effect of LAS on removing total phosphorus(TP)in the artificial rapid infiltration land treatment system(ARI).Results showed that removal efficiency of TP in ARI increasingly declined with concentration of LAS increased in wastewater.In the condition of prolonging drying time,removal efficiency of TP increased,and that was evident with increase of concentration of LAS.LAS strongly affected the removal of TP in the ARI.However,LAS and TP can be removed ... |
