Drainage basin ditch water pollutant intercepting and purifying method
The invention belongs to the technical field of agricultural non-point source pollution, and particularly relates to a drainage basin ditch water pollutant intercepting and purifying method which comprises the following steps: (1) constructing an ecological ditch; (2) planting plants: planting creeping plants capable of purifying water on the soil covering strips; planting herbaceous plants capable of absorbing nitrogen and phosphorus pollutants in the planting areas, wherein the herbaceous plants comprise bermuda grass, vetiver grass and pennisetum purpureum, one kind of herbaceous plants is planted in each planting area, and the varieties of the herbaceous plants in the adjacent planting areas are different. According to the method, the farmland in the drainage basin serves as a source, stepped interception is conducted through the timber pile fences on the two sides of the ditch and the plants planted on the ditch bottom partition sections, nitrogen and phosphorus pollutants lost in the farmland are absorbed, intercepted and adsorbed by the plants planted in the ditch, and the effect that the nitrogen and phosphorus pollutants in the ditch water are reduced from the source and utilized to reduce water pollution is achieved.
本发明属于农业面源污染技术领域，具体涉及一种流域沟渠水体污染物的拦截净化方法，包括以下步骤:包括以下步骤：(1)构建生态沟渠；(2)种植植物：于所述土壤覆盖条带上种植能净化水质的匍匐植物；于所述种植区内种植可吸收氮磷污染物的草本植物，所述草本植物为狗牙根、香根草和象草，每个所述种植区内各种植一种，相邻种植区的草本植物种类不同。本发明以流域内农田为源，利用沟渠两侧木桩栅栏及沟底隔段所种植物进行梯级拦截，使得农田流失的氮磷污染物被沟渠内所种植物吸收、拦截、吸附，达到从源头降低并利用沟渠水体中氮磷污染物，以减轻水体污染的效果。
