Description

Technical Field

[0001] The embodiments of the present invention relate to the field of animal husbandry and environmental protection technology, and in particular to a pig farming wastewater denitrification and phosphorus removal treatment system. Background Art

[0002] With the large-scale development of the pig farming industry, the wastewater pollution problem it generates is becoming increasingly serious. Pig wastewater is rich in a large amount of organic matter, nutrients such as nitrogen and phosphorus, as well as pollutants such as suspended matter and pathogens. Pig wastewater that is directly discharged without proper treatment will cause a series of environmental problems, such as eutrophication of water bodies, leading to massive reproduction of algae, destroying the ecological balance of water bodies, deteriorating water quality, affecting the survival of aquatic organisms, and further affecting the safety of fisheries, agricultural irrigation and drinking water sources in surrounding waters. Traditional wastewater treatment methods have many defects in treating pig wastewater. Although some conventional biological treatment processes can decompose organic matter to a certain extent, they have limited effects on the removal of nitrogen and phosphorus, and it is difficult to meet the increasingly stringent environmental emission standards. Therefore, a pig wastewater denitrification and phosphorus removal treatment equipment is needed.

[0003] However, in actual use, the existing wastewater treatment equipment cannot spray and stir the wastewater in the entire sedimentation tank over a large area, resulting in poor neutralization effect of the dosing, and the internal surface of the wastewater treatment equipment will gradually accumulate dirt, microbial film, precipitated impurities and chemical reaction products during long-term operation. These deposits will not only reduce the treatment efficiency of the equipment, but may also cause equipment blockage and corrosion, affecting the normal operation and service life of the equipment. The existing cleaning methods are mostly manual cleaning or simple water flushing, which have the problems of incomplete cleaning, high labor intensity, low efficiency, and difficulty in effectively cleaning the complex internal structure of the equipment, thereby reducing the use efficiency of the equipment. Summary of the invention

[0004] In view of the above problems, the embodiment of the present invention provides a piggery wastewater denitrification and dephosphorization treatment system to solve the problem that the existing wastewater treatment equipment cannot spray and stir the wastewater in the entire sedimentation tank on a large scale during actual use, resulting in poor effect of adding medicine and neutralization, and the wastewater treatment equipment will gradually accumulate dirt, microbial film, precipitated impurities and chemical reaction products on its internal surface during long-term operation.

By synchronously starting the oscillators installed on the surfaces of both ends of the reaction tank, the oscillating plate is driven to swing up and down, thereby driving the cleaning drum. The cleaning drum drives the cleaning scraper to scrape along the inner wall surface of the reaction tank, and the cleaning lines can improve the scraping effect on the inner wall. In the process of scraping and cleaning, the trumpet-shaped soft cylinder will be relatively squeezed, which will produce a certain deformation and cause a certain deformation of the resistance plate. At this time, the pressure-resistant cone column supports the top of the resistance plate to prevent damage caused by excessive deformation due to compression. With the divergent setting of the pressure dividing strip, the dispersion effect of the pressure generated from above on the cleaning scraper can be enhanced, and the pressure from above can be evenly distributed, which is beneficial to improving the service life of the cleaning scraper, and will not cause deep scratches on the inner wall of the reaction tank, thereby improving the use efficiency of the reaction tank.

[0031] According to other embodiments of the present invention, Figure 3As shown, the stirring and disturbing mechanism 4 includes a fixed plate 41 fixedly mounted on the surface of one side of the reaction tank 1, a driving motor 42 is fixedly mounted on the upper surface of the fixed plate 41, a lead screw 43 is fixedly connected to the output end of the driving motor 42, a positioning plate is fixedly mounted on the upper surface of the reaction tank 1, a slide 44 is movably mounted on the surface of the lead screw 43, the bottom end of the slide 44 is slidably connected to the inside of the positioning plate, a driving box 45 is fixedly mounted on the top surface of the slide 44, and an electric telescopic rod 451 is fixedly connected to the top of the driving box 45. The bottom end of the electric telescopic rod 451 is fixedly connected to a connecting plate, the upper surface of the connecting plate is fixedly installed with a stirring motor 452, the output end of the stirring motor 452 is fixedly installed with a double-layer pulley 453, the outer surface of the double-layer pulley 453 is sleeved with two belts, the inner surfaces of the two belts are respectively movably installed with pulley 1 454 and pulley 2 455, the inner walls of pulley 1 454 and pulley 2 455 are fixedly connected with a hollow tube 46, and the outer surface of the hollow tube 46 is fixedly installed with a stirring turbulence component 461 and a nozzle 462.

[0032] In the technical solution of this embodiment, a driving motor 42 installed on the upper surface of the fixed plate 41 drives the lead screw 43 to rotate, so that the slide 44 can slide back and forth inside the positioning plate, thereby driving the driving box 45 to reciprocate. At the same time, the connecting plate is pushed down by the electric telescopic rod 451, so that the hollow tube 46 can be located inside the reaction tank 1, and then the double-layer pulley 453 is driven to rotate by the stirring motor 452, and through the transmission of two belts, the pulley 1 454 and the pulley 2 455 are driven to move synchronously, and then the stirring and turbulent flow assembly 461 on the surface of the hollow tube 46 is driven by the pulley 1 454 and the pulley 2 455 to stir. During the stirring process, the stirring motor 452 can be set to spray the medicine solution into the interior of the reaction tank 1 so as to mix with the wastewater. During the whole process, stirring while moving is beneficial to improving the mixing effect of the medicine solution and accelerating the reaction time of the medicine and the wastewater.

[0033] According to other embodiments of the present invention, Figure 4 As shown, the drug adding mechanism 5 includes a drug storage box 51 fixedly installed on the upper surface of the reaction tank 1, a drug inlet pipe 52 is fixedly intercepted on the top of the drug storage box 51, and a water pump 53 is fixedly installed on the front side surface of the drug storage box 51, both ends of the water pump 53 are fixedly connected with water inlet pipes, one end of the water inlet pipe extends to the interior of the drug storage box 51, the water delivery end of the water pump 53 is fixedly connected with an infusion pipe 54, the top of the infusion pipe 54 is fixedly installed with a liquid storage pipe 55, the outer surface of the liquid storage pipe 55 is fixedly connected with a liquid supply hose 56, and one end of the liquid supply hose 56 is fixedly connected to the top of the hollow tube 46.

[0034] In the technical solution of this embodiment, the medicine inlet pipe 52 can be used to replenish the medicine into the medicine storage box 51, and then the medicine in the medicine storage box 51 is extracted by the water pump 53, and transported to the inside of the liquid storage pipe 55 through the infusion tube 54, and then transported to the inside of the hollow tube 46 through the liquid supply hose 56, and sprayed to the inside of the reaction tank 1 by the nozzle 462, so as to mix with the wastewater, produce a chemical reaction, and then produce precipitation, thereby improving the treatment effect.

[0035] According to other embodiments of the present invention, Figure 5 , Figure 6 and Figure 7 As shown, the cleaning mechanism 6 includes an oscillator 61 fixedly mounted on the surfaces of both ends of the reaction tank 1, the output end of the oscillator 61 is fixedly connected with a oscillating plate 62, the oscillating plate 62 is located on the inner surface of the reaction tank 1, the inside of the oscillating plate 62 is movably connected with a cleaning drum 63, the outer surface of the cleaning drum 63 is fixedly mounted with a trumpet-shaped soft cylinder 64, the top of the trumpet-shaped soft cylinder 64 is fixedly mounted with a cleaning scraper 65, the surface of the cleaning scraper 65 is provided with cleaning lines 66, the upper surface of the trumpet-shaped soft cylinder 64 is fixedly mounted with a resistance plate 641, the upper surface of the resistance plate 641 is fixedly connected to the lower surface of the cleaning scraper 65, and a pressure-resistant cone column 642 is fixedly mounted inside the trumpet-shaped soft cylinder 64, and the outer surface of the pressure-resistant cone column 642 is fixedly connected with a pressure dividing strip 643.

[0036] In the technical solution of this embodiment, the oscillator 61 installed on the two end surfaces of the reaction pool 1 is synchronously started to drive the oscillating plate 62 to swing up and down, thereby driving the cleaning drum 63. The cleaning drum 63 drives the cleaning scraper 65 to scrape along the inner wall surface of the reaction pool 1, and through the cleaning lines 66, the scraping effect on the inner wall can be improved. In the process of scraping and cleaning, the trumpet-shaped soft cylinder 64 will be relatively squeezed, which will produce a certain deformation and cause a certain deformation of the resistance plate 641. At this time, the pressure-resistant cone column 642 abuts and supports the top of the resistance plate 641 to prevent the problem of damage caused by excessive deformation due to pressure. Combined with the divergent setting of the pressure dividing strip 643, the dispersion effect of the pressure generated from above on the cleaning scraper 65 can be enhanced, and the pressure from above can be evenly distributed, which is beneficial to improving the service life of the cleaning scraper 65, and will not cause deeper scratches on the inner wall of the reaction pool 1, thereby improving the use efficiency of the reaction pool 1.

[0037] The following is a detailed description of the working principle of the pig wastewater denitrification and phosphorus removal treatment system.

[0038] like Figure 1As shown in FIG. 7 , first, by utilizing the treatment equipment 2, the pig farming wastewater is infused into the interior thereof, and after the initial treatment, it flows through the outlet pipe 21 to the interior of the denitrification and dephosphorization box 3 for biological denitrification and dephosphorization treatment, and the treated wastewater is filtered again through the cooperation of the filter sponge 1 33 and the filter sponge 2 34 in the filter tube 31, and then discharged into the interior of the reaction tank 1 through the drain pipe 32 for precipitation reaction, and secondly, the medicine can be replenished into the interior of the medicine storage box 51 by utilizing the medicine inlet pipe 52, and then the medicine in the medicine storage box 51 is extracted by the water pump 53, and transported to the liquid storage tank through the infusion pipe 54. The liquid in the liquid is transported to the inside of the tube 55 through the liquid supply hose 56 to the inside of the hollow tube 46, and is sprayed to the inside of the reaction pool 1 by the nozzle 462. At the same time, the driving motor 42 installed on the upper surface of the fixed plate 41 drives the lead screw 43 to rotate, so that the slide 44 can slide back and forth inside the positioning plate, thereby driving the driving box 45 to reciprocate. At the same time, the connecting plate is pushed down by the electric telescopic rod 451, so that the hollow tube 46 can be located inside the reaction pool 1, and then the double-layer pulley 453 is driven to rotate by the stirring motor 452, and through the transmission of the two belts, the pulleys 454 and The pulley 455 moves synchronously, and the pulley 454 and the pulley 455 drive the stirring and turbulent assembly 461 on the surface of the hollow tube 46 to stir. During the stirring process, the stirring motor 452 can be set to spray the liquid medicine into the interior of the reaction tank 1 so as to mix with the wastewater. During the whole process, stirring while moving is beneficial to improving the mixing effect of the liquid medicine and accelerating the reaction time of the medicine and the wastewater. Then, at the end of use, the oscillator 61 installed on the two end surfaces of the reaction tank 1 is synchronously started to drive the oscillating plate 62 to swing up and down, thereby driving the cleaning drum 63, which is driven by the cleaning drum 63. The dynamic cleaning scraper 65 can scrape along the inner wall surface of the reaction pool 1, and through the cleaning lines 66, the scraping effect on the inner wall can be improved. In the process of scraping and cleaning, the trumpet-shaped soft tube 64 will be relatively squeezed, which will produce a certain deformation and cause a certain deformation of the resistance plate 641. At this time, the pressure-resistant cone column 642 abuts and supports the top of the resistance plate 641, and the divergent setting of the pressure dividing strip 643 can enhance the dispersion effect of the pressure generated from above on the cleaning scraper 65, evenly distribute the pressure from above, and thus will not cause deeper scratches on the inner wall of the reaction pool 1. Then, the sewage is discharged through the sewage pipe 11.
