Problems solved by technology

[0005] Wetland plants can release some dissolved oxygen through their roots, but due to the small amount released, it is difficult to meet the demand for dissolved oxygen in processes such as degradation of organic pollutants and ammonia nitrogen nitrification, so it is necessary to take measures to increase the supply level of dissolved oxygen in subsurface flow wetlands

Embodiment Construction

[0014] like figure 1 As shown, the solar-driven micro-power constructed wetland sewage treatment device includes a water inlet 1, a filling area 2, an aeration pipe 3, a plant area 4, a water outlet 5, an aerator 6, a battery 7, a solar panel 8, and the upper part of the device body A water inlet 1 is set on one side wall in the middle, and a water outlet 5 is set on the other side wall in the middle of the upper part of the device body. The aeration tube 3, the filling area 2, and the plant area 4 are arranged in sequence in the device body from bottom to top, and the aeration Pipe 3, aerator 6, storage battery 7, and solar panel 8 are connected in sequence, and filling area 2 is composed of surface soil layer, middle layer of gravel, and lower layer of small bean stone. The calcium content of the surface soil is 2.0-2.5kg / 100kg; the particle size of the gravel layer is 5-50mm, and the laying thickness is 0.4-0.7m. The texture of the soil for planting in the constructed wetl...

Abstract

The invention discloses a solar-driven micro-power artificial wetland sewage treatment device. It includes a water inlet, a filling area, an aeration tube, a plant area, a water outlet, an aerator, a battery, and a solar panel. The water inlet is set on one side wall in the upper middle of the device body, and the other side wall is set Outlet, the body of the device is provided with an aeration pipe, a filling area, and a plant area in sequence from bottom to top, and the aeration pipe, aerator, battery, and solar panels are connected in sequence. The lower layer consists of three layers of small bean stone. The beneficial effects of the present invention are as follows: ① the device can obtain sufficient dissolved oxygen through aeration, and strengthen the contact between the organic matter in the pool and the microorganisms and dissolved oxygen, thereby ensuring that the microorganisms in the pool can oxidize the organic matter in the sewage under the condition of sufficient dissolved oxygen; Decomposition. ② Through the combination of solar power generation and aeration tube, solar energy becomes the initial energy source of the sewage mixing system, reducing operating costs.

Description

technical field [0001] The invention relates to water treatment technology, in particular to a solar-driven micro-power artificial wetland sewage treatment device. Background technique [0002] Rural domestic sewage is a type of sewage with a large volume and a wide range. With the continuous improvement of rural construction and the improvement of people's living standards, the discharge of rural domestic sewage is increasing year by year, which makes rural non-point source pollution more and more serious. shift to the countryside. In addition, the composition of rural sewage is becoming more and more complex. Untreated rural domestic sewage is not only a potential threat to drinking water sources, but also an important cause of eutrophication in rivers and lakes. [0003] At present, among the methods of rural decentralized domestic sewage treatment, there are mainly unpowered anaerobic biological treatment, land treatment, artificial wetland and other processes. Constru...
