Farmland irrigation, drainage and purification treatment circulation system

Abstract

The invention relates to the technical field of farmland water conservancy irrigation, specifically to a farmland irrigation, drainage and purification treatment circulation system. The farmland irrigation, drainage and purification treatment circulation system comprises a river and a plurality of farmland irrigation systems, wherein the river provides a water source for the farmland irrigation systems; an ecological treatment system is arranged between every two adjacent farmland irrigation systems; each ecological treatment system comprises a gravel bed, a submerged plant belt, an earthwormecological wetland and a water storage pool; the outlet of a previous farmland irrigation system communicates with the first inlet of a gravel bed; the outlet of each gravel bed communicates with theinlet of a submerged plant belt; the outlet of each submerged plant belt communicates with the inlet of an earthworm ecological wetland; the first outlet of each earthworm ecological wetland is a water outlet which communicates with the inlet of a water storage pool; and the outlet pipe of each water storage pool communicates with a next farmland irrigation system. The farmland irrigation, drainage and purification treatment circulation system provided by the invention has the following advantages: the problem of non-point source pollution caused by traditional farmland irrigation to ecological rivers and lakes is solved; the application efficiency of irrigation water is improved; and the waste of water resources is reduced.

Description

technical field [0001] The invention relates to the field of farmland water conservancy irrigation technology, in particular to a farmland irrigation drainage purification treatment cycle system. Background technique [0002] my country's average total water supply is about 550 billion cubic meters, of which irrigation water consumption is about 360 billion cubic meters, and agricultural irrigation water consumption accounts for 90% of the total agricultural water consumption, making it a veritable major water user. my country's agricultural water consumption is large, and extensive irrigation has caused rural water environment pollution and water shortage problems. At present, at the end of rural areas, the construction of sewage treatment facilities does not yet have scale effect, and agricultural non-point source pollution is serious. Therefore, agricultural water conservation, as an important way to save water, increase efficiency, and control pollution, will bear the br...

Problems solved by technology

In the past, ecological farmland construction technology did not coordinate the relationship between efficient use of water resources and water purification and pollution reduction, which greatly restricted its application
