Description

Technical Field

[0001] The present application relates to the field of underground sewage treatment control technology, and in particular to a new type of high-efficiency equipment for groundwater pollution control. Background Art

[0002] Underground sewage may contain various harmful substances, such as organic matter, heavy metals, pathogens, etc. If it is discharged directly without treatment, it will pollute the soil and groundwater, affect the balance of the surrounding ecosystem, and at the same time, avoid polluting the surrounding water bodies and protect the quality of surface water. If underground sewage seeps into rivers, lakes and other water bodies, it will cause eutrophication and deterioration of water quality, affecting the survival of aquatic organisms and the sustainable use of water resources. Furthermore, underground sewage may contain pathogens such as bacteria, viruses, and parasites. If it is not treated, it may cause various diseases and pose a threat to public health. At the same time, untreated underground sewage will produce odors and harmful gases, such as hydrogen sulfide, which will affect the living environment and health of surrounding residents.

[0003] At present, the existing underground sewage treatment methods include physical treatment, chemical treatment and biological treatment. When using chemical treatment to treat underground sewage, coagulants and coagulant aids are usually added to domestic sewage. Coagulants can destabilize colloids and fine suspended matter in water and aggregate to form larger particles through mechanisms such as compression of double electrical layers, adsorption and electrical neutralization, adsorption bridging, and sediment capture. Coagulant aids mainly play the role of auxiliary coagulants to help improve the coagulation effect, such as adjusting the pH value, increasing the strength and density of flocs, and accelerating the sedimentation rate. However, in the current treatment process, coagulants and coagulant aids are usually added directly to the treatment tank, which cannot effectively achieve the auxiliary coagulation effect of coagulants on coagulants.

[0025] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

Although the embodiment of the present application provides the method operation steps shown in the following embodiments or drawings, more or fewer operation steps may be included in the method based on routine or no creative labor. In the steps where there is no necessary causal relationship logically, the execution order of these steps is not limited to the execution order provided in the embodiment of the present application.

[0027] refer to Figure 1-2 As shown, the present application provides a new type of high-efficiency equipment for groundwater pollution control, including an inclined screen well 11, a sand settling tank 12, a regulating tank 13, a reaction tank 14, a first medicine tank 21, a second medicine tank 22, a first dosing pump 31, a second dosing pump 32 and a controller 33.

[0028] The inclined screen well 11 is connected to the grit chamber 12. A screen plate 111 is arranged in the inclined screen well 11. The screen plate 111 is inclined in the vertical direction. After the liquid is filtered by the screen plate 111, it flows to the grit chamber 12. The screen plate 111 performs preliminary screening of the liquid to remove larger particles of sediment.

[0029] A sediment pump 121 is provided in the sedimentation tank 12 , and the sediment pump 121 is used to transport the sediment in the sedimentation tank 12 to the outside of the sedimentation tank 12 . The sedimentation tank 12 is connected to the regulating tank 13 , and the liquid flow in the sedimentation tank 12 is transported to the regulating tank 13 .

[0030] A sewage lifting pump 131 is provided in the regulating tank 13, and the sewage lifting pump 131 is used to transport the liquid flow in the regulating tank 13 to the reaction tank 14. A ventilation pipeline is also provided in the regulating tank 13, and the ventilation pipeline is used to transport the air flow outside the regulating tank 13 to the inside of the regulating tank 13. The reaction tank 14 is connected to the delivery pump through a pipeline, and the delivery pump transports the liquid flow in the reaction tank 14 to the outside.

[0031] The first medicine tank 21 stores coagulant, and the first medicine tank 21 is connected to the input end of the first dosing pump 31 through a pipeline. The output end of the first dosing pump 31 is connected to the top of the reaction tank 14 through a pipeline. The first dosing pump 31 transports the coagulant stored in the first medicine tank 21 to the reaction tank 14.

[0032] The second medicine tank 22 stores a coagulant aid, and the second medicine tank 22 is connected to the input end of the second dosing pump 32 through a pipeline. The output end of the second dosing pump 32 is connected to the top of the reaction tank 14 through a pipeline. The second dosing pump 32 transports the coagulant stored in the second medicine tank 22 to the reaction tank 14.

[0033] Agitators are respectively arranged on the first medicine tank 21 and the second medicine tank 22, and the output end of the agitator is connected to a stirring shaft. The stirring shaft is driven by the agitator to rotate inside the first medicine tank 21 or the second medicine tank 22, thereby preventing the coagulant and the coagulant aid from being deposited in the first medicine tank 21 and the second medicine tank 22 respectively.

[0034] A first partition 41, a second partition 42 and a diverter plate 43 are arranged in the reaction tank 14, wherein the first partition 41 and the second partition 42 are arranged at the top of the reaction tank 14 in the vertical direction, wherein the connection position between the output end of the first dosing pump 31 and the top of the reaction tank 14 is located between the side wall of the reaction tank 14 and the first partition 41, and the connection position between the output end of the second dosing pump 32 and the top of the reaction tank 14 is located between the first partition 41 and the second partition 42, specifically, the connection position between the output end of the second dosing pump 32 and the top of the reaction tank 14 is located between the diverter plate 43 and the second partition 42.

[0035] The diverter plate 43 is arranged at the bottom of the reaction tank 14 along the vertical direction and between the first baffle plate 41 and the second baffle plate 42. A guide plate is arranged on the top of the diverter plate 43. The guide plate includes a first plate body 431 and a second plate body 432. The first plate body 431 and the second plate body 432 are connected to the top of the diverter plate 43, and the angle between the first plate body 431 and the second plate body 432 is an obtuse angle. The angle between the first plate body 431 or the second plate body 432 and the diverter plate 43 is an obtuse angle.

[0036] Specifically, the bottoms of the first partition plate 41 and the second partition plate 42 form a gap with the bottom of the reaction tank 14 in the vertical direction, and the top of the diverter plate 43 forms a gap with the top of the reaction tank 14 in the vertical direction.

[0037] Therefore, the coagulant delivered by the first dosing pump 31 is guided and a delivery channel is formed through the first partition 41 and the diverter plate 43. When the coagulant is delivered to the upper part of the diverter plate 43, it is diffused and diverted by the guide plate, and the direction of the diffused diversion is toward both sides of the delivery direction of the coagulant, so as to achieve better mixing of the coagulant and the coagulant aid delivered subsequently.

[0038] The obtuse structure formed between the first plate body 431 and the second plate body 432 changes the flow cross-sectional shape of the entire diverter plate. Compared with a straight plate structure, this obtuse structure makes the flow path of the coagulant relatively tortuous when it flows through here. The flow direction of the coagulant needs to change when passing through the connection between the first plate body 431 and the second plate body 432, thereby reducing the flow rate of the coagulant. This can make the transportation of the coagulant more stable, reduce unstable phenomena such as turbulence and splashing that may be caused by excessive flow rate, and facilitate the accurate and uniform transportation of the coagulant to the target location.

[0039] A slower flow rate also allows the coagulant more time to mix and react during the transportation process. For coagulants that need to be fully mixed, it can improve their mixing effect and reaction efficiency, thereby better playing the role of the coagulant.

[0040] The obtuse angle structure of the first plate 431 and the second plate 432 can guide the flow of the coagulant to a certain extent. When the coagulant flows into the diverter plate from one direction, the first plate 431 and the second plate 432 can divide it into two or more directions of flow, and due to the existence of the obtuse angle, this diversion will be more uniform. For example, in some application scenarios where the coagulant needs to be transported to multiple different locations at the same time, this uniform diversion feature can ensure that each location can receive an appropriate amount of coagulant, ensuring the normal operation of the entire system.

[0041] Uniform diversion can also reduce the situation where there is too much or too little coagulant in some local areas, and avoid problems such as poor treatment effect in some areas or equipment blockage due to uneven distribution of coagulant.

[0042] During the transportation of coagulants, instantaneous pressure shocks may be generated due to the start and stop of the pump, the opening and closing of the valve, and other operations. Compared with the straight plate structure, the obtuse-angled diverter plate can support each other on both sides, thereby enhancing the overall structural strength. When encountering a pressure shock, the first plate 431 and the second plate 432 can jointly withstand the impact force, reduce the deformation and damage of the diverter plate, and thus ensure that the transportation of the coagulant is not affected. This enhanced impact resistance also helps to extend the service life of the diverter plate and reduce the maintenance cost of the equipment.

[0043] The obtuse angle structure design of the first plate body 431 and the second plate body 432 may make the corners inside the diverter plate relatively small, reducing the possibility of coagulant accumulation in the corners. After the equipment has been running for a period of time, when the diverter plate needs to be cleaned and maintained, this structure can make the cleaning work easier and improve the efficiency and effect of cleaning.

[0044] The controller 33 is connected to the first dosing pump 31 and the second dosing pump 32 , and is used to adjust the working power of the first dosing pump 31 and the second dosing pump 32 , wherein the controller 33 is configured to adjust the working power of the second dosing pump 32 according to the working power of the first dosing pump 31 .

[0045] Specifically, the controller 33 is configured to: if the working power of the first dosing pump 31 is greater than or equal to the first preset power, drive the second dosing pump 32 to operate at the first power; otherwise, drive the second dosing pump 32 to operate at the second power, wherein the first preset power is a preset value and can be set to 60% of the maximum power of the first dosing pump 31.

[0046] The first power is 50% of the maximum power of the second dosing pump 32 , and the second power is 80% of the maximum power of the second dosing pump 32 .

[0047] When the working power of the first dosing pump 31 is greater than or equal to the first preset power, the second dosing pump 32 is driven to operate at a lower working power, so that the output end of the second dosing pump 32 can be connected to the top of the reaction tank 14 through a pipeline, and when the first dosing pump 31 operates at a higher power, it is avoided that the second dosing pump 32 still operates at a higher working power, thereby causing a greater interference effect on the mixing of the coagulant and the coagulant aid at the diverter plate 43 or the guide plate, thereby generating a larger turbulence or mixing inside, thereby reducing the liquid flow delivery efficiency.

[0048] When the first dosing pump 31 is running at a relatively low power, that is, when the working power of the first dosing pump 31 is less than the first preset power, the working power of the second dosing pump 32 can be increased so that the coagulant delivered by the second dosing pump 32 can be better mixed, and when the coagulant is delivered at a relatively low flow rate, the flow rate of the coagulant can be appropriately increased so that better mixing can be achieved through the increased flow rate of the coagulant. Therefore, by adjusting the working power of the second dosing pump 32 according to the working power of the first dosing pump 31, the mixing performance can be achieved when the liquid flow at the diverter plate 43 is in a variety of flow states such as mixing and diversion.

[0049] The underground sewage liquid flow is transported to the inclined screen well 11 and filtered by the screen plate 111. The sediment is precipitated and filtered in the sand settling tank 12 and then transported outward by the sediment pump 121. The liquid flow then enters the regulating tank 13 for treatment, and then the liquid flow is transported to the reaction tank 14 and the coagulant and coagulant aid are injected into the reaction tank 14. The first partition 41, the second partition 42 and the diverter plate 43 are respectively arranged in the reaction tank 14. Under the arrangement of the first partition 41 and the diverter plate 43, the first dosing The coagulant delivered by the pump 31 is transported under the guidance of the first partition 41 and the diverter plate 43, and a guide plate is set on the top of the diverter plate 43 to realize the diversion of the coagulant, so as to improve the mixing effect of the coagulant and the coagulant aid. The controller 33 adjusts the working power of the second dosing pump 32 according to the working power of the first dosing pump 31 to improve the mixing effect of the coagulant and the coagulant aid, thereby improving the fusion performance of the coagulant aid and the coagulant to improve the treatment and governance performance of underground sewage.
