Integrated w-shaped farmland ecological retreat ditch

Abstract

The invention relates to an integrated W-shaped farmland ecological liquid waste ditch, belongs to the fields of agricultural cleaner production and water environment restoration, and aims to solve the problems that the amount of pollutants in current farmland liquid waste is large, and severe pollution is caused when such pollutants enter natural body. The farmland ecological liquid waste ditch comprises a quick drainage channel, a purifying channel, a semi-concrete embankment, an infiltration dam and an ecological revetment, wherein the infiltration dam is arranged at the middle of the ditch bottom of the farmland ecological liquid waste ditch; the quick drainage channel is formed between the semi-concrete embankment and the infiltration dam; the sinking purifying channel is formed between the ecological revetment and the infiltration dam; the infiltration dam is positioned in the purifying channel; aquatic plants are grown at the channel bottom of the purifying channel; the infiltration dam is formed by fixing a steel wire mesh on stumps; and aquatic plants are grown at the dam top of the infiltration dam. The drainage capacity of the multi-functional farmland ecological liquid waste ditch provided by the invention can be guaranteed; and meanwhile, the farmland liquid waste can be purified, surplus water resources can be retained, and pollution-reducing and amount-reducing discharge of the farmland liquid waste can be realized.

Description

technical field [0001] The invention belongs to the fields of agricultural clean production and water body environment restoration, and in particular relates to an integrated ecological drainage channel which improves the existing farmland drainage channel and integrates the functions of "drainage-cleaning-storage". Background technique [0002] At present, my country's agricultural production has the problems of large amount of agrochemical input and low utilization rate. Excessive nitrogen and phosphorus pollutants are quickly discharged into natural water bodies as farmland recedes into drainage channels, and high-concentration and large-scale pollutants It not only pollutes natural water bodies, but also wastes resources due to a large amount of receding water not being effectively utilized. Although the existing conventional single-canal drainage ditches can quickly drain water to a certain extent, such single canals do not have the functions of water level adjustment an...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to solve the problem that the existing farmland dewatering water has a large amount and high concentration of pollutants, and directly enters the natural water body to cause serious pollution, and provides a "drain-clean-storage" integrated high-efficiency ecological purification of farmland dewatering water. ditch
