Ecological ditch for reducing pollutants in paddy field drainage

Abstract

The invention provides an ecological ditch for reducing pollutants in paddy field drainage. By arranging a water conservation valve in the ecological ditch and an ecological intercepting box containing an ecological substrate bed and biological film fillers, laying ecological concrete mixtures on a ditch wall and the bottom of the ditch, and planting adaptive plants in through holes of the ditch wall and the bottom of the ditch and planting adaptive plants on the ecological substrate bed, the scour of the paddy field drainage to the ditch and plant seedlings is weakened; the ditch wall and thebottom of the ditch are stabilized; the purifying capacity of the ditch to the paddy field drainage is increased; the total amount of the pollutants in the paddy field drainage entering a downstreamaccommodating water body is reduced; the possibility of occurrence of eutrophication in the downstream accommodating water body is reduced; the biological diversity and landscape feature of a paddy field area are increased; a living environment is created for wild animals and plants; and meanwhile, the economic income of farmers can be effectively increased due to the fact that economic class plants are planted in the ecological ditch.

Description

technical field [0001] The invention relates to the technical field of environmental pollution prevention and water and soil conservation, in particular to an ecological ditch for reducing pollutants in paddy field drainage. Background technique [0002] As the "regulator" of farmland water and the "connector" of water flow between rivers and lakes, farmland drainage ditches have the hydraulic and ecological functions of coordinating farmland drainage. the role of things. [0003] During farmland drainage and rainy seasons, drainage ditches can timely dredge excess water in the farmland, especially in paddy fields, excessive water seriously affects the growth of crops and easily leads to the loss of nutrients in paddy fields. In dry seasons, the temporary water in the ditches can supplement the farmland, so drainage The ditches can effectively regulate the water in agricultural areas, and at the same time, they can also collect agricultural non-point source pollution and tr...
