Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, specifically to a wastewater treatment device. Background Technology
[0002] Wastewater refers to water discharged from domestic and industrial sources that has been polluted to a certain extent. Water that has lost its original function is simply called wastewater. It mainly refers to water used for domestic purposes, which contains a relatively high amount of organic matter and is relatively easy to treat. From the perspective of wastewater sources, wastewater can be defined as liquid or water carrying waste that is discharged from residential, government, commercial, or industrial areas and mixed with groundwater, surface water, and even blizzard conditions. As is well known, wastewater treatment facilities are generally required during the treatment process.
[0003] However, existing sewage treatment devices are not effective enough in purifying sewage, and the inlet pipe is prone to clogging during the treatment process, affecting the device's efficiency. Therefore, they do not meet the current needs, and we propose a new sewage treatment device. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a sewage treatment device.

[0011] Preferably, one side of the neutralizing liquid pipe is connected to the neutralizing liquid tank via a connecting pipe, and the inner surface of the neutralizing liquid pipe is uniformly provided with through holes.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. This utility model uses a coarse filter screen installed inside the inlet cylinder to filter large impurities in the sewage before it is sent into the main body, reducing the blockage of the working pipes in the main body and improving the working efficiency of the device. Then, using the sealing plug and sealing ring installed below the coarse filter screen, the sealing plug can be removed after the work is completed, and the impurities above the coarse filter screen can be uniformly treated. After the sewage enters the main body, the scraper, fine filter screen and stirring rod installed above the working chamber can increase the flow of sewage, reduce the blockage of the fine filter screen and improve the subsequent purification effect of sewage.
[0014] 2. This utility model utilizes a U-shaped groove, a biofilm, a neutralizing liquid, and activated carbon adsorption rods set inside the purification plate. The U-shaped groove reduces the flow rate of sewage, while the biofilm increases the contact time between the sewage and the biofilm, improving the purification effect. The activated carbon adsorption rods 22 at both ends of the U-shaped groove and the activated carbon adsorption net 29 below effectively absorb odors and harmful substances from the sewage. The neutralizing liquid inside the neutralizing liquid pipe neutralizes the acidity and alkalinity of the sewage, reducing soil pollution from the discharged water. After the purified sewage enters the storage tank, the collection pipe and sampling pipe on one side of the storage tank can be used to test the purified liquid. If it fails the test, the secondary inlet pipe and water pump on one side of the main body can be used to send the water back to the top of the purification plate for secondary purification, thus improving the purification effect of the device.

It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0021] like Figure 1 and Figure 2 As shown, a wastewater treatment device of this utility model includes a main body 6, a cover plate 2 on the top of the main body 6, a motor 1 on the upper surface of the cover plate 2, an inlet cylinder 4 on one side of the upper end of the main body 6, the inlet cylinder 4 and the main body 6 are fixedly connected by a connecting ring 5, a connecting pipe 3 is provided at the upper end of the inlet cylinder 4, a secondary inlet pipe 9 is provided on the other side of the upper end of the main body 6, a collection pipe 7 is provided on one side of the lower end of the main body 6, a drain pipe 10 is provided on the other side of the lower end of the main body 6, and a neutralization liquid tank 8 is provided on the front end face of the main body 6.
[0022] As a preferred technical solution in this embodiment, such as Figure 3As shown, the inner lining of the main body 6 is provided with a working chamber 11. A fine filter screen 24 is installed inside the working chamber 11. A connecting shaft 12 is installed inside the fine filter screen 24. A scraper 13 is installed on one side of the connecting shaft 12 above the fine filter screen 24. Circular holes 14 are evenly distributed on the inner side of the scraper 13. Stirring rods 15 are evenly distributed on the outer surface of the connecting shaft 12 below the fine filter screen 24. A purification plate 16 is installed at the lower end of the connecting shaft 12. An activated carbon adsorption mesh 29 is installed below the purification plate 16. A liquid storage chamber 20 is installed below the activated carbon adsorption mesh 29. A water pump 21 is installed at one end of the secondary liquid inlet pipe 9. A collection pipe 7 is provided with… The device includes a sampling tube 19, a U-shaped groove 18 on the inner side of the purification plate 16, a biofilm 23 on the inner wall of the U-shaped groove 18, activated carbon adsorption rods 22 evenly arranged on the inner sides of both ends of the U-shaped groove 18, and a neutralization liquid pipe 17 on the inner side of the U-shaped groove 18. The U-shaped groove reduces the flow rate of sewage, and the biofilm increases the contact time between sewage and biofilm, improving the purification effect of biofilm. The activated carbon adsorption rods 22 at both ends of the U-shaped groove 18 and the activated carbon adsorption net 29 below can effectively absorb the odor and harmful substances in the sewage, improving the purification effect of the device.
[0023] As a preferred technical solution in this embodiment, such as Figure 4 As shown, a coarse filter screen 25 is provided inside the liquid inlet cylinder 4, a support rod 26 is provided below the coarse filter screen 25, a sealing plug 27 is provided at the lower end of the support rod 26, and sealing rings 28 are evenly arranged between the sealing plug 27 and the liquid inlet cylinder 4. By using the coarse filter screen, large impurities in the sewage can be filtered before the sewage is sent into the main body 6 by the liquid inlet cylinder 4, reducing the blockage of the working pipes in the main body 6 and improving the working efficiency of the device.
[0024] Working Principle: During use, the connecting pipe 3 is connected to the sewage outlet. The coarse filter 25 inside the inlet cylinder 4 filters large impurities in the sewage before it enters the main body 6, reducing pipe blockage and improving efficiency. The sealing plug 27 and sealing ring 28 below the coarse filter 25 allow for the removal of the sealing plug 27 after operation, cleaning the impurities above the coarse filter 25. After the sewage enters the main body 6, the scraper 13, fine filter 24, and stirring rod 15 above the working chamber 11 increase flow, reducing clogging of the fine filter 24 and improving subsequent purification. The U-shaped groove 18, biofilm 23, neutralization liquid pipe 17, and activated carbon adsorption rod 22 inside the purification plate 16 further enhance the purification process. The U-shaped trough 18 reduces the flow rate of sewage. The biofilm 23 increases the contact time between the sewage and the biofilm 23, improving the purification effect of the biofilm 23. The activated carbon adsorption rods 22 at both ends of the U-shaped trough 18 and the activated carbon adsorption net 29 below can effectively absorb the odor and harmful substances in the sewage. The neutralizing liquid inside the neutralizing liquid pipe 17 can neutralize the acidity and alkalinity of the sewage, reducing the pollution of the discharged water to the soil. After the purified sewage enters the storage tank 20, the collection pipe 7 and sampling pipe 19 on one side of the storage tank 20 can be used to test the purified liquid. If it is unqualified, the secondary inlet pipe 9 and water pump 21 on one side of the main body 6 can be used to send the water back to the top of the purification plate 16 for secondary purification, improving the purification effect of the device.
