Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and in particular to a garden landscape sewage purification treatment device and a use method thereof. Background Art

[0002] With the acceleration of urbanization and the rapid development of the landscape industry, landscape water bodies (such as artificial lakes, landscape ponds, and streams) in various parks, scenic areas, and residential gardens have become an important component of improving environmental quality. However, these landscape water bodies are generally facing pollution problems. The deterioration of their water quality not only affects the landscape effect, but also may disrupt the ecological balance and threaten the surrounding environment and human health. Therefore, the demand for purification and treatment of landscape wastewater is becoming increasingly urgent. At present, the treatment methods for garden landscape sewage usually adopt physical filtration and chemical dosing methods. The reagents that are proportioned with the amount of sewage need to be added to the sewage treatment pool for reaction. Due to the large space size and capacity of the sewage pool, it is difficult for the reagents to fully contact and react with the sewage, affecting the treatment effect and efficiency of the sewage. When using physical filtration to filter and purify impurities in sewage, traditional sewage filters usually adopt a top-down filtration method. This filtration method easily causes solid impurities to accumulate rapidly on the surface of the filter element, forming a filter cake layer, which not only increases water flow resistance, but also reduces filtration efficiency. Moreover, when the filter element needs to be cleaned, it is often necessary to cut off the water flow, disassemble the filter for manual cleaning or replace the filter element. Not only is the operation cumbersome and time-consuming, it will also cause intermittent shutdown of the sewage treatment system, affecting the continuity of water treatment.

[0012] A method for using a garden landscape sewage purification treatment device, the method comprising the following steps: When purifying garden landscape sewage, external sewage will be discharged into the sewage pool. During this process, the stop valve at the bottom of the sewage pool is in a closed state, causing the liquid level in the sewage pool to rise. When the sewage rises to the position of the discharge hole, the sewage will flow into the isolation box. Since floating objects will be on the upper layer of the sewage, the floating objects will pass through the discharge hole with the water flow and fall into the isolation box. The floating objects will be collected by the coarse filter in the isolation box. When cleaning impurities in the isolation box, the upper box cover is opened to expose the opening on the top of the isolation box to the outside, so as to clean the floating objects and impurities inside. Secondly, the sewage will flow into the main pipe through the diversion pipe at the bottom of the isolation box. When the flow rate of sewage flowing into the sewage pool is large, because the overflow pipe is located above the discharge hole, the sewage will submerge the discharge hole and be discharged from the overflow pipe, preventing the sewage in the sewage pool from overflowing; By opening the check valve on the main pipe, the sewage inside the sewage pool flows into the turnover drum through the main pipe, and the medicine pump is controlled to extract the medicine liquid from the outside. The medicine liquid passes through the liquid guide pipe and the one-way valve and enters the medicine application box, and is discharged through multiple medicine discharge holes on the outside of the medicine application box. Since the medicine application box is conical in design and located in the center of the turnover drum, the sewage discharged from the main pipe will impact the conical surface outside the medicine application box, thereby increasing the contact area between the sewage and the medicine liquid, ensuring sufficient contact between the sewage and the medicine liquid and improving the reaction effect. The one-way valve provided between the medicine application box and the liquid guide pipe will prevent the sewage from passing through the medicine application box into the liquid guide pipe, thereby preventing backflow and improving the stability of medicine application. Secondly, the sewage mixed with the medicine liquid enters the sedimentation tank through the discharge pipe; Since the highest water level in the purification tank is lower than the lowest water level in the sewage pool, the sewage level in the sedimentation tank will gradually rise until it fills the entire sedimentation tank and the purification tank. In this process, the sewage will enter the purification component through the through-holes in the isolation disc, and the sewage will first contact the filter element inside the purification component and be purified and filtered by the filter element. Then the sewage will be discharged from the micropores outside the filter element and enter the filter cartridge, and finally filtered again by the filter holes in the filter cartridge. The treated sewage will pass through the filter holes and be located in the space between the purification tank and the filter cartridge. When extracting the sewage inside the purification tank for further treatment, the liquid pump is started to pump water from the inside of the purification tank and discharge the water through the drain pipe. Since the highest water level in the purification tank is lower than the lowest water level in the sewage pool, the purification tank and the sedimentation tank are always kept full, thereby improving the continuity of sewage treatment, and the sediment produced by sewage precipitation will accumulate at the bottom of the sedimentation tank, which can be discharged by opening the cleaning valve, thereby improving the convenience of operation. When cleaning the purification component to improve the purification effect, start the motor to drive the connecting shaft to rotate, and the connecting shaft drives the deflector to rotate through the rotating plate. The deflector rotates sixty degrees against the bottom of the isolation disk and is located under one of the through holes, so as to prevent the sewage in the sedimentation tank from entering the purification component through the through hole. Since impurities are trapped on the inner side of the filter element, when backflushing the filter element, open the drain valve outside the drain pipe, and the filter cartridge and the filter element are backwashed with the clean water after filtering. Due to the pressure difference between the water pressure in the purification box and the atmospheric pressure, the purified water flows in reverse to remove impurities trapped on the filter hole and the inner wall of the filter element. The impurities are discharged into the deflector through the through hole, and the inverted cone The designed air deflector will concentrate the impurities into the recoil pipe, which will then guide the impurities into the connecting pipe and flow them into the sewage pipe from the rotary joint, so that the sewage pipe can discharge the impurities. Because the ends of the connecting pipe and the sewage pipe are connected by a rotary joint, the normal conduction between the connecting pipe and the sewage pipe is guaranteed without affecting the rotation of the rotating plate and the air deflector driven by the connecting shaft. When the cleaning work of a single purification component is completed, the motor drives the rotating plate to rotate another sixty degrees through the connecting shaft, so that the rotating plate drives the air deflector to move to the bottom of the next through hole to perform recoil cleaning on the upper purification component. When the air deflector rotates one circle, the recoil cleaning work of all purification components is completed, and the sewage pipe is closed.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention drives the deflector to rotate by the rotating plate, and the deflector rotates sixty degrees against the bottom of the isolation disk and is located below one of the through holes, so as to prevent the sewage in the sedimentation tank from entering the purification component through the through hole. Since impurities are trapped on the inner side of the filter element, when the filter element is backflushed, the drain valve outside the drain pipe is opened, and the filter cartridge and the filter element are backwashed with the clean water after filtering. Due to the pressure difference between the water pressure in the purification box and the atmospheric pressure, the purified water flows in the reverse direction to remove impurities trapped on the filter holes and the inner wall of the filter element. The impurities are discharged into the deflector through the through hole. The deflector with an inverted cone design will concentrate the impurities and guide them into the backflush pipe. The backflush pipe then guides the impurities into the connecting pipe and flows into the drain pipe from the rotary joint, so that the drain pipe can discharge the impurities. Because the ends of the connecting pipe and the sewage pipe are connected by a rotary joint, the normal conduction between the connecting pipe and the sewage pipe is guaranteed without affecting the rotation of the rotating plate and the deflector driven by the connecting shaft. When the cleaning work of a single purification component is completed, the motor drives the rotating plate to rotate another 60 degrees through the connecting shaft, so that the rotating plate drives the deflector to move to the bottom of the next through hole to perform backwash cleaning on the upper purification component. When the deflector rotates one circle, the backwash cleaning work of all purification components is completed. In addition, the device can accumulate some sediment at the bottom of the sedimentation box through the bottom-up filtering method, reducing the burden on the filter element. Moreover, when cleaning the purification component, there is no need to cut off the water flow and remove the purification component for treatment, thereby ensuring the continuity of water treatment in the sewage treatment system. 2. The present invention opens the check valve to allow the sewage inside the sewage pool to flow into the turnover drum through the main pipe, controls the medicine pump to extract medicine liquid from the outside, and the medicine liquid passes through the liquid guide pipe and the one-way valve and enters the medicine application box, so that the medicine liquid is discharged through multiple discharge holes on the outside of the medicine application box. Since the medicine application box is conical in design and located at the center of the turnover drum, the sewage discharged from the main pipe will impact the conical surface outside the medicine application box, thereby increasing the contact area between the sewage and the medicine liquid, ensuring sufficient contact between the sewage and the medicine liquid, and improving the reaction effect and efficiency. In addition, the one-way valve provided between the medicine application box and the liquid guide pipe will prevent the sewage from entering the liquid guide pipe through the medicine application box, thereby preventing backflow and improving the stability of medicine application.

[0028] A method for using a garden landscape sewage purification treatment device, the method comprising the following steps: When purifying garden landscape sewage, external sewage will be discharged into the sewage pool 2. During this process, the stop valve 8 at the bottom of the sewage pool 2 is in a closed state, causing the liquid level in the sewage pool 2 to rise. When the sewage rises to the position of the discharge hole 4, the sewage will flow into the isolation box 301. Since floating objects will be on the upper layer of the sewage, the floating objects will pass through the discharge hole 4 with the water flow and fall into the isolation box 301. The floating objects will be collected by the coarse filter 302 in the isolation box 301. When cleaning impurities in the isolation box 301, the upper box cover 304 is opened to expose the opening at the top of the isolation box 301 to the outside, so as to clean the floating impurities inside. Then, the sewage will flow into the main pipe 7 through the diversion pipe 303 at the bottom of the isolation box 301. When the flow rate of sewage flowing into the sewage pool 2 is large, because the overflow pipe 5 is located above the discharge hole 4, the sewage will submerge the discharge hole 4 and be discharged from the overflow pipe 5, preventing the sewage in the sewage pool 2 from overflowing. By opening the stop valve 8 on the main pipe 7, the sewage inside the sewage pool 2 flows into the turnover drum 9 through the main pipe 7, and the medicine pump 101 is controlled to work to extract the medicine liquid from the outside. The medicine liquid passes through the liquid guide pipe 102 and the one-way valve 105 and enters the medicine application box 103, and the medicine liquid is discharged through the multiple medicine discharge holes 104 outside the medicine application box 103. Since the medicine application box 103 is conical in design and located at the center of the turnover drum 9, the sewage discharged from the main pipe 7 will impact the conical surface outside the medicine application box 103, thereby increasing the contact area between the sewage and the medicine liquid, so that the sewage and the medicine liquid are fully in contact and the reaction effect is improved. The one-way valve 105 provided between the medicine application box 103 and the liquid guide pipe 102 will prevent the sewage from passing through the medicine application box 103 into the liquid guide pipe 102, thereby preventing backflow and improving the stability of medicine application. Secondly, the sewage mixed with the medicine liquid enters the sedimentation tank 12 through the discharge pipe 11; Since the highest water level of the purification tank 14 is lower than the lowest water level of the sewage tank 2, the sewage level in the sedimentation tank 12 will gradually rise until it fills the entire sedimentation tank 12 and the purification tank 14. During this process, the sewage will enter the purification component 21 through the through hole 20 in the isolation disk 19. The sewage will first contact the filter element 213 inside the purification component 21, and the sewage will be purified and filtered by the filter element 213. Then, the sewage will be discharged from the micropores outside the filter element 213 and enter the filter cartridge 211, and finally filtered again by the filter hole 212 in the filter cartridge 211. The treated sewage The filter 212 passes through the filter hole 212 and is located in the space between the purification box 14 and the filter cartridge 211. When extracting the sewage inside the purification box 14 for further subsequent treatment, the liquid pump 17 is started to pump water from the inside of the purification box 14 and discharge the water through the drain pipe 18. Since the highest water level of the purification box 14 is lower than the lowest water level of the sewage tank 2, the purification box 14 and the sedimentation box 12 are always kept full, thereby improving the continuity of sewage treatment. The sediment generated by the sewage precipitation will accumulate at the bottom of the sedimentation box 12, and the sediment can be discharged by opening the cleaning valve 27, thereby improving the convenience of operation. When cleaning the purification component 21 to improve the purification effect, the motor 221 is started to drive the connecting shaft 222 to rotate, and the connecting shaft 222 drives the deflector 242 to rotate through the rotating plate 241. The deflector 242 is rotated sixty degrees along the bottom of the isolation disk 19 and is located below one of the through holes 20, thereby preventing the sewage in the sedimentation tank 12 from entering the purification component 21 through the through hole 20. Since impurities are trapped on the inner side of the filter element 213, when backflushing the filter element 213, the drain valve 26 outside the drain pipe 25 is opened, and the filter cartridge 211 and the filter element 213 are backwashed with the filtered clean water. Due to the pressure difference between the water pressure in the purification box 14 and the atmospheric pressure, the purified water flows in the reverse direction to remove impurities trapped on the filter hole 212 and the inner wall of the filter element 213. The impurities are discharged into the deflector 242 through the through hole 20. The cover 242 will concentrate the impurities into the backwash pipe 243, and the backwash pipe 243 will then guide the impurities into the connecting pipe 245 and flow them into the drain pipe 25 from the rotary joint 246, so that the drain pipe 25 can discharge the impurities. Because the connecting pipe 245 is connected to the end of the drain pipe 25 by a rotary joint 246, the normal conduction between the connecting pipe 245 and the drain pipe 25 is guaranteed without affecting the rotation of the rotating plate 241 and the deflector cover 242 driven by the connecting shaft 222. When the cleaning work of a single purification component 21 is completed, the motor 221 drives the rotating plate 241 to rotate another sixty degrees through the connecting shaft 222, so that the rotating plate 241 drives the deflector cover 242 to move to the bottom of the next through hole 20 to backwash the upper purification component 21. When the deflector cover 242 rotates one circle, the backwash cleaning work of all purification components 21 is completed, and the drain pipe 25 is closed.

9. A method for using a garden landscape sewage purification treatment device, according to any one of claims 1 to 8, characterized in that: The method of use comprises the following steps: When purifying garden landscape sewage, external sewage will be discharged into the sewage pool (2). During this process, the stop valve (8) at the bottom of the sewage pool (2) is in a closed state, causing the liquid level in the sewage pool (2) to rise. When the sewage rises to the position of the discharge hole (4), the sewage will flow into the isolation box (301). Since floating objects will be on the upper layer of the sewage, the floating objects will pass through the discharge hole (4) with the water flow and fall into the isolation box (301). The floating objects will be collected by the coarse filter (302) in the isolation box (301). When cleaning impurities in the isolation box (301), the upper box cover (304) is opened to expose the opening at the top of the isolation box (301) to the outside, so that floating impurities inside can be cleaned. Then, the sewage flows into the main pipe (7) through the guide pipe (303) at the bottom of the isolation box (301). When the flow rate of sewage flowing into the sewage pool (2) is large, the overflow pipe (5) is located above the discharge hole (4), and the sewage will flood the discharge hole (4) and be discharged from the overflow pipe (5), thereby preventing the sewage in the sewage pool (2) from overflowing. By opening the stop valve (8) on the main pipe (7), the sewage in the sewage pool (2) flows into the turnover drum (9) through the main pipe (7), and the medicine pump (101) is controlled to extract the medicine liquid from the outside. The medicine liquid passes through the liquid guide tube (102) and the one-way valve (105) and enters the medicine application box (103), and the medicine liquid is discharged through the multiple medicine discharge holes (104) outside the medicine application box (103). Since the medicine application box (103) is conical in design and is located at the center of the turnover drum (9), the main pipe is (7) The discharged sewage will impact the conical surface outside the drug application box (103), thereby increasing the contact area between the sewage and the drug solution, so that the sewage and the drug solution are fully in contact, thereby improving the reaction effect. In addition, the one-way valve (105) provided between the drug application box (103) and the liquid guide tube (102) will prevent the sewage from passing through the drug application box (103) and entering the liquid guide tube (102), thereby playing a role in preventing backflow and thus improving the stability of drug application. Secondly, the sewage mixed with the drug solution enters the sedimentation tank (12) through the discharge pipe (11); Since the highest water level of the purification tank (14) is lower than the lowest water level of the sewage tank (2), the sewage level in the sedimentation tank (12) will gradually rise until it fills the entire sedimentation tank (12) and the purification tank (14). During this process, the sewage will enter the purification component (21) through the through hole (20) in the isolation disk (19). The sewage will first contact the filter element (213) inside the purification component (21) and be purified and filtered by the filter element (213). Then, the sewage will be discharged from the micropores outside the filter element (213) and enter the filter cartridge (211). Finally, it will be filtered again by the filter hole (212) in the filter cartridge (211). The sewage passes through the filter hole (212) and is located in the space between the purification box (14) and the filter cartridge (211). When the sewage inside the purification box (14) is extracted for further subsequent treatment, the liquid extraction pump (17) is started to pump water from the inside of the purification box (14) and discharge the water through the drain pipe (18). Since the highest water level of the purification box (14) is lower than the lowest water level of the sewage pool (2), the purification box (14) and the sedimentation box (12) are always kept full, thereby improving the continuity of sewage treatment. The sediment generated by the sedimentation of the sewage will accumulate at the bottom of the sedimentation box (12). The sediment can be discharged by opening the cleaning valve (27), thereby improving the convenience of operation. When cleaning the purification component (21) to improve the purification effect, the motor (221) is started to drive the connecting shaft (222) to rotate, and the connecting shaft (222) drives the guide cover (242) to rotate through the rotating plate (241). The guide cover (242) rotates sixty degrees along the bottom of the isolation disk (19) and is located below one of the through holes (20), thereby preventing the sewage in the sedimentation tank (12) from entering the purification component (21) through the through hole (20). Since impurities are trapped in the filter element ( 213), when backwashing the filter element (213), the drain valve (26) outside the drain pipe (25) is opened, and the filter cartridge (211) and the filter element (213) are backwashed with the purified water after filtration. Due to the pressure difference between the water pressure in the purification box (14) and the atmospheric pressure, the purified water flows in the reverse direction to remove the impurities trapped on the filter hole (212) and the inner wall of the filter element (213), and the impurities are discharged into the guide cover (242) through the through hole (20). The guide cover (242) with an inverted cone design is 42) will concentrate the impurities into the recoil pipe (243), and then the recoil pipe (243) will guide the impurities into the connecting pipe (245) and flow into the sewage pipe (25) from the rotary joint (246), so that the sewage pipe (25) can discharge the impurities. Because the connecting pipe (245) and the end of the sewage pipe (25) are connected by the rotary joint (246), the connecting pipe (245) and the sewage pipe (25) are ensured to be connected without affecting the rotation of the rotating plate (241) and the guide cover (242) driven by the connecting shaft (222). (25) and the like. When the cleaning work of a single purification component (21) is completed, the motor (221) drives the rotating plate (241) to rotate sixty degrees again through the connecting shaft (222), so that the rotating plate (241) drives the guide cover (242) to move to the bottom of the next through hole (20) to perform backwash cleaning on the upper purification component (21). After the guide cover (242) rotates one circle, the backwash cleaning work of all purification components (21) is completed, and the sewage pipe (25) is closed.
