垫江县次级河流环境现状分析

Investigation on the Current Environment Condition of Secondary River in Dianjiang County

垫江县次级河流部分水质指标不容乐观,以种植污染、养殖污染和生活污染为代表的农村面源污染日渐成为垫江河流污染的主要因素。改变垫江河流水质现状,必须尽量减少化肥农药施用,改变传统养殖模式,完善农村垃圾收运系统,加快建设农村废水治理设施。

The water-quality index of some secondary rivers in Dianjiang County seems not so optimistic. The rural non-point source pollution, mainly the planting pollution, aquaculture pollution and domestic pollution are increasingly becoming the major factors of the river pollution in Dianjiang. In order to change the status of river water quality in Dianjiang, we must minimize the usage of fertilizer pesticide, change the traditional farming model to improve the rural garbage removal system, and accelerate the construction of wastewater treatment facilities in rural areas.
