[0002] Livestock and poultry wastewater refers to the feces, urine, and sewage produced during livestock and poultry farming. Livestock and poultry wastewater primarily comes from livestock excrement (feces and urine) and flushing water from the farming process. This wastewater contains large amounts of organic matter, nitrogen, phosphorus, and other nutrients, which are key characteristics of its role as a non-point source of agricultural pollution and its potential resource utilization.

[0003] The existing multi-stage harmless treatment equipment for livestock and poultry manure and sewage has the following problems: The existing multi-stage harmless treatment equipment for livestock and poultry manure and sewage cannot re-proportion the nutrients in the sewage, so that the sewage with high nutrient concentration is directly used to irrigate crops or fruit trees after filtration. In the process of long-term application of fertilizer and water, salt accumulation in the soil will occur, destroying the soil structure, affecting soil fertility and crop growth. Therefore, it cannot meet the existing demand for the use of multi-stage harmless treatment equipment for livestock and poultry manure and sewage. Summary of the Invention

[0004] In view of the above situation, in order to overcome the defects of the existing technology, this solution provides a multi-stage harmless treatment equipment for livestock and poultry manure and sewage that can re-proportion the nutrients in the sewage to ensure that the nutrient concentration of the sewage is not too high when it is returned to the field.

[0005] The technical solution adopted in this scheme is as follows: This scheme proposes a multi-stage harmless treatment equipment for livestock and poultry manure and sewage, including a base, a filter box, a height-adjustable filtrate mechanism and a controlled-maintenance proportioning mechanism. The base is arranged on the bottom walls at both ends of the filter box. The height-adjustable filtrate mechanism includes a filter mechanism, a destroyer mechanism, a jet mechanism and a temperature difference mechanism. The filter mechanism is arranged on the side wall of the filter box, the destroyer mechanism is arranged on the upper wall of the filter box, the jet mechanism is arranged on the side of the filter box close to the destroyer mechanism, and the temperature difference mechanism is arranged on the side of the filter box close to the jet mechanism.

The suction mechanism is arranged on the bottom wall of the base, the release mechanism is arranged on the upper wall of the filter box, and the infusion mechanism is arranged between the suction mechanism and the release mechanism.

[0006] As a further preferred embodiment of the present invention, the filtering mechanism includes a sewage pump, a sewage pipe and a filter screen. Multiple groups of the sewage pumps are arranged on the bottom side wall of one side of the filter box.

The guide groove is set through, and the arc tube is connected between the jet tube and the filter box; the temperature difference mechanism includes a temperature-conducting copper tube and a temperature-difference power generation sheet, the temperature-difference power generation sheet is arranged on the side of the filter box close to the jet tube, and the temperature-conducting copper tube passes through the jet tube and is arranged between the copper block and the temperature difference end of the temperature-difference power generation sheet.

[0007] When in use, the sewage pump uses the pumping end to extract the sewage inside the livestock and poultry manure sewage pool. The livestock and poultry manure sewage enters the filter box through the sewage pipe, the rotary liquid valve is opened, the chemical pipe is connected to the organic matter decomposition bacteria liquid cylinder, the opening of the liquid valve is controlled, and the organic matter decomposition bacteria liquid inside the organic matter decomposition bacteria liquid cylinder is pre-flowed into the mixing box through the chemical pipe. The sewage is mixed with the organic matter decomposition bacteria liquid falling into the mixing box through the disinfection port to remove the organic matter in the sewage, which is convenient for subsequent sewage recycling and treatment. After being filtered by the filter mesh, the sewage flows into the arc tube. The sewage inside the arc tube hits the copper block inside the jet tube when falling. Under the jet effect, the falling sewage can lower the temperature of the copper block. The copper block cools one end of the thermoelectric generator through the heat-conducting copper tube, causing a temperature difference at both ends of the thermoelectric generator, storing the current generated by the temperature difference of the thermoelectric generator, and the sewage passes through the guide groove and falls to the bottom of the jet tube.

[0008] Preferably, the suction mechanism includes a suction box, a heat preservation partition, a zeolite layer, a drain valve and a thermoelectric cooling plate group, multiple groups of the suction boxes are arranged on the bottom wall of the base, and the height of the bottom wall of the suction box gradually decreases from one end close to the jet tube to the other end. The heat preservation partition is arranged on the inner wall of the suction box, and the heat preservation partition divides the suction box into two cavities. The zeolite layers are respectively arranged in the cavities on both sides of the heat preservation partition. The drain valve is symmetrically arranged on the bottom wall of the suction box away from the jet tube. The drain valve is connected to the suction box. The thermoelectric cooling plate group is symmetrically arranged on the bottom wall of the suction box. The heating end of the thermoelectric cooling plate group is arranged through the interior of the suction box; the release mechanism includes an organic acid box, an acid distribution pump, and an acid delivery pipe and an acid delivery valve, the organic acid tank is arranged on the upper wall of one end of the filter box away from the jet frame, the acid distribution pump is symmetrically arranged on the side wall of the organic acid tank, the liquid extraction end of the acid distribution pump is arranged through the inside of the organic acid tank, the acid delivery pipe is arranged on the liquid discharge end of the acid distribution pump, the acid delivery valve is symmetrically arranged on the upper wall of one end of the suction box close to the jet tube, and the acid inlet pipe is connected between the acid delivery pipe and the acid delivery valve; the infusion mechanism includes a downpipe, an electric valve and a U-shaped tube, the downpipe is connected to the bottom wall of the jet tube, the electric valve is symmetrically arranged on one side of the suction box close to the downpipe, the electric valve is connected to the suction box, the U-shaped tube is connected between the electric valves, and the end of the downpipe away from the jet tube is connected to the U-shaped tube.

[0009] When in use, the sewage that falls into the bottom of the jet tube enters the U-shaped tube through the downpipe, the electric valve near the left side of the suction box is in the on state, and the electric valve near the right side of the suction box is in the blocked state. The sewage inside the U-shaped tube flows into the cavity near the left side of the suction box, and the corresponding drain valve is opened. The sewage after filtration and adsorption by the zeolite layer is discharged through the drain valve. When the filtration time of the zeolite layer reaches the time specified by the operator, the electric valve and drain valve near the left side of the suction box are closed respectively, and the electric valve and drain valve near the right side of the suction box are opened respectively. The acid delivery valve near the end where the filtration operation is not performed is opened, and the acid pump draws the organic acid inside the organic acid tank through the liquid extraction end. The organic acid is transported to the acid inlet pipe through the acid delivery pipe, and the organic acid inside the acid inlet pipe flows into the suction box. Since the bottom wall of the suction box is inclined, the organic acid entering the suction box can penetrate the zeolite layer inside the suction box, and the organic acid is used to release the nitrogen, phosphorus and other nutrients adsorbed in the zeolite layer. By controlling the opening of the corresponding drain valve, the nitrogen, phosphorus and other nutrients are returned to the purified livestock and poultry manure and sewage, and the nutrient elements in the livestock and poultry manure and sewage are re-proportioned, thereby reducing the nutrient concentration of the livestock and poultry manure and sewage when it is used as farmland return, ensuring the growth quality of crops and fruit trees irrigated with the livestock and poultry manure and sewage, and improving the resource utilization rate of the livestock and poultry manure and sewage.

[0010] Specifically, the side walls of the organic acid tank are respectively provided with a controller and a rectifier.

[0011] Wherein, a battery is provided on the side of the suction box away from the electric valve.

[0012] Preferably, the controller is electrically connected to the sewage pump, the acid distribution pump and the electric valve respectively.

[0013] Furthermore, the rectifier is electrically connected to the thermoelectric generator and the battery respectively.

[0014] The beneficial effects achieved by adopting the above structure are as follows: Compared with the existing technology, this solution adopts a combination of a jet energy collection structure and a temperature-raising reaction-promoting structure. Through the provision of a height-adjusting filtrate mechanism and a controlled-maintenance proportioning mechanism, with the coordinated use of the filtering mechanism, the elimination mechanism, the jet mechanism, the temperature difference mechanism, the absorption mechanism, the release mechanism and the infusion mechanism, the jet energy generated by the impact force of the sewage is used to reduce the temperature of the copper block, so that a temperature difference is generated at both ends of the thermoelectric power generation plate. The current generated by the temperature difference phenomenon at both ends of the thermoelectric power generation plate is used to power the thermoelectric cooling plate group. The thermoelectric cooling plate group accelerates the reaction rate of the zeolite layer and the organic acid, increases the release of nutrients inside the zeolite layer, controls the opening of the drain valve, and can re-proportion the nutrients in the purified sewage, so that the nutrients in the sewage are changed from an uncontrollable state to a controllable state, facilitates the return of sewage to the fields, and improves the irrigation quality of crops.

[0023] The side walls of the organic acid tank 30 are respectively provided with a controller 36 and a rectifier 37 .

[0024] A battery 38 is provided on a side of the suction box 25 away from the electric valve 34 .

[0026] The rectifier 37 is electrically connected to the thermoelectric generator 22 and the battery 38 respectively.

[0027] During specific use, the pumping end of the sewage pump 5 is connected to the livestock and poultry manure sewage pool through a pipeline, and the controller 36 controls the sewage pump 5 to start. The sewage pump 5 uses the pumping end to extract the sewage inside the livestock and poultry manure sewage pool, and the livestock and poultry manure sewage enters the filter box 2 through the sewage pipe 6. The lower liquid valve 10 is manually rotated to open, and the chemical pipe 13 is connected to the organic matter decomposing bacteria liquid cylinder 9. The opening of the lower liquid valve 10 is controlled, and the organic matter decomposing bacteria liquid inside the organic matter decomposing bacteria liquid cylinder 9 is preliminarily flowed into the mixing box 11 through the chemical pipe 13. The sewage is mixed with the organic matter decomposing bacteria liquid falling into the mixing box 11 through the disinfection port 12, and the organic matter in the sewage is processed to facilitate the subsequent recycling of the sewage. The metabolic pathway of the microorganisms in the organic matter decomposing bacteria liquid mainly revolves around the decomposition of organic matter.

When there are many impurities adsorbed on the surface of the filter screen 7, the filter screen 7 is removed and cleaned, and a new filter screen 7 is replaced for use. As it falls, the sewage inside the arc tube 19 impacts the copper block 17 inside the jet tube 16. Under the jet effect, the falling sewage lowers the temperature of the copper block 17.

The sewage passes through the guide groove 18 and falls into the bottom of the jet tube 16. The sewage falling into the bottom of the jet tube 16 enters the interior of the U-shaped tube 35 through the downpipe 33. The controller 36 controls the electric valve 34 near the left side of the suction box 25 to open. The electric valve 34 near the left side of the suction box 25 is in a conducting state, and the electric valve 34 near the right side of the suction box 25 is in a blocked state. The sewage inside the U-shaped tube 35 flows into the cavity near the left side of the suction box 25. The zeolite layer 27 inside the cavity near the left side of the suction box 25 adsorbs nutrients such as nitrogen and phosphorus in the sewage. The corresponding drain valve 28 is manually opened, and the sewage filtered and adsorbed by the zeolite layer 27 is discharged through the drain valve 28. The drain valve 28 is connected to the sewage recovery pool through a pipeline. The sewage containing organic matter decomposition bacteria liquid flows into the sewage recovery pool through the pipeline for storage. When the filtration time of the zeolite layer 27 reaches the time specified by the operator, the electric valve 34 and the drain valve 28 near the left side of the suction box 25 are closed respectively, and the electric valve 34 and the drain valve 28 near the right side of the suction box 25 are opened respectively. The acid delivery valve 41 near the end of the suction box 25 where no filtration operation is performed is opened, and the controller 36 controls the acid preparation pump 31 to start. The acid preparation pump 31 delivers the organic acid in the organic acid tank 30 to the acid inlet pipe 42 through the liquid pumping end. The organic acid in the acid inlet pipe 42 flows into the suction box 25. Since the bottom wall of the suction box 25 is inclined, the organic acid entering the suction box 25 is The organic acid inside the culture box 25 can penetrate the zeolite layer 27 inside the suction culture box 25, and the organic acid is used to release the nitrogen, phosphorus and other nutrients adsorbed inside the zeolite layer 27. By controlling the opening of the corresponding drain valve 28, the nitrogen, phosphorus and other nutrients are returned to the purified livestock and poultry manure and sewage, thereby re-proportioning the nutrients in the livestock and poultry manure and sewage, reducing the nutrient concentration of the livestock and poultry manure and sewage when it is used as farmland, ensuring the growth quality of crops or fruit trees irrigated with the livestock and poultry manure and sewage, improving the resource utilization rate of the livestock and poultry manure and sewage, and regularly changing the path of the sewage flowing into the internal cavity of the suction culture box 25; The battery 38 is charged in advance, and the battery 38 supplies power to the thermoelectric cooling plate group 39. The thermoelectric cooling plate group 39 heats the cavity into which the organic acid is introduced through the heating end. Increasing the ambient temperature inside the cavity can accelerate the rate of the chemical reaction between the organic acid and the zeolite layer 27, and improve the release efficiency of the nutrients inside the zeolite layer 27. The above operation can be repeated the next time it is used.
