非点源污染的本质是农村生态系统严重失调,为控制和削减进入受纳水体径流的污染负荷,各种治理技术措施得到相应发展,滞留塘便是其中之一,通过对都拉乡河道滞留塘技术的研究与分析,发现处理前总氮（TN）、氨氮（NH3-N）、总磷（TP）和悬浮颗粒物平均浓度分别为8.75mg.L-1,2.97mg.L-1,0.54mg.L-1,24.0mg.L-1;处理后总氮（TN）、氨氮（NH3-N）、总磷（TP）和悬浮颗粒物平均浓度分别为6.04mg.L-1,1.66mg.L-1,0.18mg.L-1,12.0mg.L-1。各项污染物平均去除率分别为31.0%,44.1%,66.7%,51.9%,滞留塘系统对氮、磷及悬浮颗粒物的截留效果较好。

Nonpoint pollution from rural areas is the results of the ecosystem degradation , On-stream detention pond system （OSDPS） is all ecological technology, which is suitable and promising for purification restoration of polluted small-scale streams in China, Studying pollutants removal performance of OSDPS is meaningful. The results suggested that the removal rate of On-stream Detention Pond System for TN, NH3-N, TP and SS were 31.0% , 44. 1% ,66. 7% and 51.9%. To improve the polluted river water detreating system in Guizhou mountainious areas making it have high rate of removing nitrogn and phosphoruse, sample manegement, and low costs, a step detention pond - wetland ecological purification restoration technique for mountain areas pollution restoration was developed and applied based on the local land features.
