Treatment device for recycling micro-invasive excavation multi-medium subsurface leachate as water for cultivation

Abstract

The invention provides a treatment device for recycling micro-invasive excavation multi-medium subsurface leachate as water for cultivation. The treatment device is characterized in that an auxiliary device and a water distribution device are connected above a water collecting device with a height difference of 3 meters; the structure of the auxiliary device is that compound calcium carbonate particles are filled between two layers of wire entanglements; the water distribution device is composed of a plurality of water distribution tanks arranged in parallel, a composite geo-membrane is laid on the inner periphery of each water distribution tank, the composite geo-membrane is filled with gravel, a water distribution pipe is buried in the gravel and a water hole is formed in the wall of the water distribution pipe; each water distribution tank has a slope; the water collecting device is composed of a plurality of water collecting tanks arranged in parallel and the water collecting tanks are filled with gravel; a water receiving pipe is laid in parallel with the water distribution tanks and a water hole is formed in the wall of the water receiving pipe; the water receiving pipe has a slope; one end of each water distribution pipe in the water distribution device is connected with a water inlet pipe, and the other end of the corresponding water inlet pipe of the water receiving pipe in the water collecting device is connected with a water outlet pipe; the water outlet pipe is connected with a collecting basin, a submersible sewage pump of the collecting basin is connected to a return pipe, and the return pipe is connected to 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 and reuse for breeding water. Background technique [0002] With the rapid economic development, a large amount of industrial waste water and domestic sewage are discharged into lakes and reservoirs. The pollution of lakes and reservoirs is increasing, and the number of pathogenic microorganisms is increasing. The problem of water purification in ponds surrounding lakes and reservoirs is increasingly caused. Pay attention. [0003] According to statistics, the water consumption of forestry, animal husbandry and fishery in my country in 2011 was 28.38 billion m 3 In the northwest region, water shortage is a prominent problem. Therefore, in order to develop aquaculture in Northwest China, it is necessary to have a simple, easy-to-use and low-cost water recycling system to purify residents' domestic w...

Problems solved by technology

At present, the main methods of water sterilization in aquaculture include physical methods, chemical methods and biological methods, but all sterilization requires centralized pipe network and centralized treatment, which is not suitable for the northwest region with vast land area and scattered population.
