Description

Technical Field

[0001] The invention relates to the field of rural sewage and solid waste treatment equipment, and in particular to a sewage discharge system based on the transformation of rural dry toilets. Background Art

[0002] In recent years, the daily water consumption and domestic sewage discharge per capita in rural areas have increased sharply, resulting in a large amount of domestic sewage. Due to the limited conditions before, a large amount of sewage was discharged in an unordered manner, becoming an important source of pollution in the rural environment. Therefore, it is necessary to strengthen the collection and treatment of rural domestic sewage to reduce the pollution of rural water bodies, soil and industries caused by direct discharge of domestic sewage.

[0003] The natural villages have a small population. With the support of relevant national policies, the permanent population of villages now ranges from several hundred to several thousand people, resulting in a reduction in the daily production of domestic sewage. Before the transformation of dry toilets, the sewage in the villages mainly came from the shower water, kitchen sewage and daily cleaning wastewater discharged by the villagers in their daily lives. The pollutants in rural domestic sewage are mainly organic matter, including cellulose, starch, sugar, fat, protein, etc., as well as inorganic salts such as nitrogen and phosphorus. It basically does not contain heavy metals and toxic and harmful substances, and the sewage has good biodegradability.

[0004] After the renovation of dry toilets, toilet feces flushing water has been added as a new source of sewage in the villages. Farmers can no longer use farmyard manure directly for fertilization as before. After toilet feces flushing water enters the septic tank, it precipitates, ferments, reacts, and the degraded sewage is no longer suitable for fertilization. Due to the small amount and incomplete supporting facilities, the sewage entering the village toilets at this stage cannot achieve the planned treatment effect. In serious cases, it even causes the existing sewage treatment system to be paralyzed or has a serious impact on the surrounding discharge environment.

[0005] The existing sewage is first treated in a septic tank, and all pollutants are degraded to a certain extent. Then, it is collected and transported to the sewage treatment stations in each village through the sewage pipes built simultaneously. However, some villages are large and the terrain is undulating. A lifting pump station needs to be set up in the middle to lift the sewage to the sewage treatment station. Due to the low density of houses in the village and the scattered distribution, if a pipeline is built, the pipeline will be very long, the terrain conditions are not optimistic, and the water flows completely by gravity potential energy. If the sewage discharge is not large, the sewage will not reach the centralized sewage treatment station. It may be deposited inside the pipeline due to temperature, blockage and other factors on the way. In addition, the water volume of the sewage treatment station in operation often does not reach the designed scale, which will cause the sewage treatment station to exist in name only. In addition, due to limited capital investment, some pipe networks are difficult to arrange, and the facilities in the system are not comprehensive. The water volume of the sewage treatment station in operation often does not reach the designed scale. There is an urgent need for a sewage system concept based on the transformation of rural dry toilets that can directly solve the source problem. Summary of the invention

[0006] In order to solve the above problems, the present invention provides a sewage discharge system based on the transformation of rural dry toilets.

[0007] The present invention adopts the following technical solution:

[0009] Furthermore, the box body A is a sealed double-layer tempered glass container containing a rotating piece inside, the rotating pieces are respectively arranged on both sides of the box body A, and the interlayer of the box body A is provided with ultraviolet light lines.

[0010] Furthermore, the upper part of the box body B is an umbrella-shaped black copper sheet, the lower part is a black copper box with air diffusion holes on the surface, and the middle part is a black copper bar for connecting the umbrella-shaped black copper sheet and the black copper box.

[0011] Furthermore, the material switch box includes a control switch and a storage box, and high-concentration ozone water and water-absorbing resin are placed in the storage box.

[0012] The sewage discharge method using the above-mentioned sewage discharge system based on the transformation of rural dry toilets is as follows: after the sewage generated by the household odor-proof flush squat toilet is treated and degraded by the three-chamber septic tank, the control switch of the material switch box is pressed, and high-concentration ozone water is used to flush the pipe between the water outlet of the household odor-proof flush squat toilet and the box A, and the water-absorbing resin is used to absorb water and solidify the mixed liquid. The sewage is discharged into the box A through the pipe, and the toothed structure inside the box is linked by wind and water flow to break and stir the dirt, so that the dirt can smoothly enter the detachable pipe sleeve and then be discharged into the box B. The umbrella-shaped black copper sheet of the box B absorbs the heat from the sun, so that the entire box 7 is always at a high temperature and dry, reducing the volume of pollutants. The umbrella-shaped structure prevents excessive moisture inside the box B even if it rains. All source treatments can be completed through the above procedures. At this time, the purified dirt can be centrally transported to the treatment station for incineration.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The present invention provides a sewage discharge system based on the transformation of rural dry toilets that can directly solve the source problem. The present invention proposes to carry out pollutant purification treatment at the outlet of the septic tank after the transformation of the dry toilet, and achieve disinfection, sterilization and deodorization effects through high-concentration ozone water and ultraviolet irradiation, and achieve solidification and drying effects through water-absorbing resin. The collection box made of copper material can maintain the shape and dry state of the dirt when exposed to sunlight.

[0015] The use of the present invention can largely avoid the problem that the existing sewage treatment system is paralyzed or has a serious impact on the surrounding discharge environment due to the sewage entering the village toilet failing to achieve the planned treatment effect. The device has good corrosion resistance and a long service life. It can directly solve the problem of rural sewage discharge source under conditions such as small sewage discharge volume, incomplete supporting facilities, and poor pipeline construction conditions.
