【摘要】 农业非点源污染作为我国地表水的主要污染来源已经成为环境科技领域关注与研究的热点问题。目前,解决非点源污染的主要途径包括多水塘系统、缓冲带、湿地处理以及降水促渗等技术。其中以施用高聚物为促渗手段,强化降水向土壤中渗透的技术,是从源头上控制非点源污染的有效措施。为此综述了高聚物改良土壤,增加土壤对降水的渗透性,延缓并削减降水地表径流,降低非点源污染负荷的效用,以期拓宽我国非点源污染控制的技术途径。更多还原

【Abstract】 Non-point pollution as one of the most important water pollution source has already become the research focus in the field of envi-ronmental pollution control.The control technologies include multi-pond systems,buffer zone,wetland systems,improving the infiltration of precipitation and soon.High polymers can be used to improve the infiltration of precipitation in order to reduce the water body pollution from non-point.This paper discusses the effects ofhigh polymers in accelerating the infiltration and decreasing the overland runoff and the pollu-tion loads with several references.更多还原
