A minimally invasive excavation multi-media underground percolation treatment device for irrigation water

Abstract

The invention discloses a treatment device for recycling mini-invasively excavated multi-medium subsurface infiltrate for irrigation water. An auxiliary device and a water distributing device are connected and arranged above a water collecting device, and height difference is 2m; the structure of the auxiliary device is that compound calcium carbonate particles are filled between two layers of wire meshes; the water distributing device comprises a plurality of water distributing slots arranged in parallel; a composite geo-membrane is paved at the periphery in each water distributing slot; gravel is filled in the composite geo-membranes, and a water distributing tube is packaged in the gravel, and water holes are formed on the tube wall of the water distributing tube; the water distributing slot is provided with a gradient; the water collecting device comprises a plurality of water collecting slots arranged in parallel; gravel is filled in the water collecting slots; a water receiving tube and the water distributing slot are paved in parallel, and a water hole is formed on the tube wall of the water receiving tube; the water receiving tube is provided with the gradient; one end of the water distributing tube in the water distributing device is connected with a water inlet tube; the other end of the water receiving tube in the water collecting device corresponding to the water inlet tube is connected with a water outlet tube; the water outlet tube is connected with a water collecting tank; a sewage submersible sewage pump of the water collecting tank is connected with a backflow tube; the backflow tube is connected in the auxiliary device.

Description

technical field [0001] The invention relates to a sewage treatment device, in particular to a treatment device for minimally invasive excavation and multi-medium underground percolation to be used for irrigation water. Background technique [0002] Agriculture is the industry that consumes the most water in my country, with a total water consumption of 400 billion m 3 , accounting for more than 70% of the total water consumption, of which the farmland irrigation water consumption is 360 billion to 380 billion m 3 , accounting for 90%-95% of agricultural water consumption. The average annual water shortage of agricultural irrigation is more than 30 billion m 3 , the average annual drought-affected area is 21.4667 million hm 2 , accounting for 1 / 5 of the country's arable land, with a disaster-affected area of ​​8.6 million hectares 2 , 10 billion to 15 billion kg of grain is reduced each year due to drought. [0003] The northwest region of my country is deeply inland, wi...
