A kind of solar micro power sewage treatment equipment

technical field

The utility model relates to a sewage treatment equipment, in particular to a solar micro-power sewage treatment equipment.

Background technique

The sewage generated in my country's rural areas reaches tens of billions of tons every year, and its main source is various sewage mixtures such as various washing water and human feces stored in people's daily life. However, most villages do not have effective sewage treatment facilities, and the sewage is random. Discharge into the surrounding water system, causing pollution to surface water and groundwater, resulting in eutrophication of surface water, and gradual deterioration of groundwater quality. At present, more than 80% of the rivers in the country are polluted to varying degrees. Nearly 700 million people in rural my country have excessive E. coli in their drinking water, and 170 million people have organic pollution in their drinking water.

At present, there are many treatment technologies for rural domestic sewage treatment at home and abroad, but they can usually be classified into two categories in terms of process principles: the first category is natural treatment systems, which use the principles of soil filtration, plant absorption and microbial decomposition, also known as ecological systems. Treatment system; the second type is biological treatment system, which can be divided into anaerobic biological treatment and aerobic biological treatment. Anaerobic biological treatment is to use the metabolic process of anaerobic microorganisms to convert refractory high-molecular organic matter in sewage into low-molecular organic matter or inorganic matter. Aerobic biological treatment is to oxygenate sewage through power equipment, cultivate aerobic microorganisms, and use microbial strains to decompose, consume and absorb organic matter, nitrogen and phosphorus in sewage.

Due to the large population in rural areas, scattered living, and lack of funds, domestic sewage cannot be treated in a centralized manner like cities, and rural sewage has the characteristics of low carbon and high nitrogen and phosphorus. Therefore, it is easy to operate, effective in pollution control, and low in operating costs. Sewage treatment Craftsmanship is imperative.

Detailed ways

In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings:

As shown in Figure 1, it is the structure of solar micro-power sewage treatment equipment, which includes: water inlet pipe 1, water collection well 2, upflow anaerobic fixed bed 7, aerobic moving bed 12, secondary sedimentation tank 15 and solar power generation device 18;

The upflow anaerobic fixed bed is set on the right side of the water collection well;

The aerobic moving bed is arranged on the right side of the upflow anaerobic fixed bed, and is connected with the upflow anaerobic fixed bed;

The secondary settling tank is arranged on the right side of the aerobic moving bed and connected with the aerobic moving bed.

A grid 3 is arranged inside the above-mentioned water collection well; a regulating tank 4 is provided at the bottom of the above-mentioned water collecting well, and a sewage lifting pump 6 and a perforated aeration pipe 5 are arranged at the bottom of the regulating pond, and the perforated aeration pipe is connected with a micro Power blower19. Aeration is mainly used to stir the sewage, and the lift pump is used to lift the sewage to the next treatment device. The above-mentioned grille is used to intercept larger suspended solids and garbage in the sewage.

A pulse water distributor 8 is installed on the upper part of the above-mentioned upflow anaerobic fixed bed, a water distribution pipe 10 is arranged at the bottom, and a water outlet weir 11 is arranged around it. The pulse water distributor is designed according to the requirements of the anaerobic process on the water flow state and the mixing of mud and water. It is composed of a cylinder, a siphon generator, and an exhaust device. Form a periodic pulse water intake, increase the stirring intensity, combined with the hydraulic optimization design of the water distribution pipe at the bottom of the pool, form a set of high-efficiency, energy-saving, reliable operation of the water distribution system, and improve the efficiency of hydrolysis and anaerobic treatment. The inside of the above-mentioned upflow anaerobic fixed bed is provided with a combined packing device 9, and the structure of the combined packing device is to change the buckle of the plastic disc into a double-circle large plastic ring, and press the aldehyde fiber or polyester filament on the ring of the ring. The inner ring is a snowflake-like plastic branch, on which a large amount of anaerobic biofilm grows. Through the water distribution pipe at the bottom of the upflow anaerobic fixed bed, the incoming water is in full contact with the anaerobic biofilm, and a large amount of anaerobic biofilm in the wastewater Part of the refractory organic matter can be removed, and the biochemical property of the wastewater can be improved.

A microporous aeration head 14 is installed at the bottom of the above-mentioned aerobic moving bed, a water inlet weir is arranged on the left side, and a water outlet weir is arranged on the right side.

There are a large number of holes on the "diaphragm", the most important part of the above-mentioned microporous aeration head. When the air is supplied, the holes are opened to form micro-bubbles, and when the wind is stopped, the holes are automatically closed. It prevents sewage and sundries from entering the pipeline and prevents the aeration head from being blocked. The microporous aeration head has excellent corrosion resistance and oxidation resistance, and has the advantages of light weight, high strength, fine and uniform bubbles, and no clogging. When the sewage passes through the aerobic moving bed, the microorganisms in the water continue to attach and grow on the inner and outer surfaces of the mobile packing, forming a biofilm. The mobile filler rotates freely under the agitation of the mixed liquid in the reactor, and the biofilm fully contacts and decomposes the pollutants in the water body, so that the water quality is purified. The stirring of the mixed liquid, the movement of the mobile filler and the growth of aerobic microorganisms are realized by the aeration of the microporous aeration head at the bottom of the pool.

A diversion cylinder 16 is installed inside the secondary settling tank, a sludge return pipe 17 is arranged at the bottom, and overflow weirs are arranged around it.
