Description
Technical Field
[0001] The utility model relates to the technical field of sewage treatment, in particular to a non-domestic sewage regulating pool. Background Art
[0002] With the continuous development of industrial and agricultural activities, the discharge of non-domestic sewage is increasing, which poses new challenges to environmental protection and water resource management. In the water treatment process, the design of sewage regulating tanks is particularly important for the treatment requirements of non-domestic sewage. The sewage regulating tank is used to adjust the water quality and water volume to ensure the stable operation of the water treatment system and the effluent quality meets the standards. It can effectively reduce the impact of the peak flow rate and concentration changes of the influent on the system, thereby ensuring the stability of the system operation and maintaining the effluent quality in compliance with the standards for a long time. Especially when dealing with anaerobic reactions that are sensitive to water quality, water volume and shock loads, a properly designed regulating tank is crucial. It can provide strong buffering capacity, reduce changes in system load, ensure the stable addition of treatment agents, and effectively control water quality and pH value, reducing the use of regulating agents.
[0003] Existing sewage regulating tanks are usually large in size. Settlement joints are structural joints between standard sections of the pool that are set to adapt to the settlement of the pool structure and temperature expansion and deformation. It is crucial to do a good job of leak-proof construction of the settlement joints. However, the traditional settlement joint design is often simply to set a waterproof filling material with a certain elasticity. Since the sewage regulating tank is in a harsh environment for a long time, the settlement joint is prone to erosion and rupture, which leads to sewage leakage problems. Considering that sewage regulating tanks usually have a large amount of water flow and a large storage capacity, once a leak occurs, the leakage volume is far greater than that of an ordinary storage tank, and if the leak is not discovered and stopped in time, it will cause serious pollution to the environment. Therefore, how to avoid leakage in sewage regulating tanks and ensure the stable operation of the system and the protection of the environment is a problem that needs to be solved at this stage.

DETAILED DESCRIPTION
[0020] The embodiments described below are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] See also Figure 1 as well as Figure 2The present embodiment provides a non-domestic sewage regulating tank, including a regulating tank body 1, wherein the regulating tank body 1 includes a side wall 10 and a bottom wall 11, and a settlement joint 12 is provided on the side wall 10 and the bottom wall 11 at a predetermined distance. In the present application, the regulating tank body 1 is a square regulating tank body 1, which includes four side walls 10 and a bottom wall 11 connected in the first position, wherein a dosing pipe 13 is arranged at the top of one of the side walls 10 in the width direction, and the dosing pipe 13 is connected to a dosing tank through a dosing pump, and an inlet pipe 14 is arranged at a certain distance below the dosing pipe 13 of the side wall 10, and the inlet pipe 14 is used to introduce non-domestic sewage, and a water inlet flow valve is arranged at the water inlet end of the inlet pipe 14 to control the size of the inlet flow or close the inlet pipe 14, and a liquid outlet pipe 15 is arranged at a certain distance above the bottom of the other side wall 10 in the width direction, and a liquid outlet regulating valve is arranged on the liquid outlet pipe 15 and is connected to a liquid outlet pump, and the liquid outlet regulating valve is used to control the size of the liquid outlet of the liquid outlet pipe 15, and the liquid outlet pump pumps the treated sewage to the next process and realizes the control of the size of the water outlet.
[0022] See also Figure 2 Specifically, a copper sheet 20 with a V-shaped or wavy middle part is arranged in the settlement joint 12, and the two ends of the copper sheet 20 are respectively cast and arranged in the side walls 10 or the bottom wall 11 on both sides of the settlement joint 12. The side of the settlement joint 12 close to the inner side of the regulating tank body 1 is provided with an asphalt felt layer 21, a polymer compound layer 22 and a waterproof and anti-corrosion layer 23 in sequence, and the side of the settlement joint 12 away from the inner side of the regulating tank body 1 is provided with an asphalt filling layer 24. In the present application, the polymer compound layer 22 is a polyurethane layer, and the waterproof and anti-corrosion layer 23 is a polyurea waterproof surface layer. As the polymer compound layer 22, the polyurethane layer has excellent waterproof performance and can effectively prevent moisture from penetrating into the settlement joint 12; and as the waterproof and anti-corrosion layer 23, the polyurea waterproof surface layer not only has excellent waterproof performance, but also has excellent anti-corrosion properties, can resist corrosive substances in sewage, and avoid the materials in the settlement joint 12 from being corroded by sewage. The asphalt filling layer 24 can be tightly filled in the settlement joint 12 to ensure the sealing of the settlement joint 12, prevent moisture and corrosive substances from entering the settlement joint 12 from the outside, and further enhance the waterproof and anti-corrosion effect. At the same time, the asphalt filling layer 24 can also provide a certain degree of flexibility to adapt to the uneven settlement of the foundation and ensure the stability and safety of the regulating pool structure.
[0023] See also Figure 2Preferably, the regulating tank body 1 is a reinforced concrete cast structure, in which steel bars 25 are arranged, and the steel bars 25 in the middle of the settlement joint 12 in the side wall 10 and the bottom wall 11 are arranged as a V-shaped or X-shaped cross structure, and the copper sheet 20 is welded and arranged in the cross structure. The use of reinforced concrete structure in the regulating tank body 1 has a higher bearing capacity and good force-bearing performance, providing a solid foundation for the regulating tank. Secondly, the copper sheet 20 is welded in the cross structure. On the one hand, the steel bars 25 at the connection have a certain ductility, so that it can better cope with settlement. On the other hand, it ensures the close connection between the copper sheet 20 and the surrounding structure. The support of the steel bars 25 also enhances the stability and force-bearing capacity of the copper sheet 20. This connection method enables the copper sheet 20 to better exert its flexibility and elastic ductility, adapt to the settlement deformation of the foundation, and maintain the sealing and integrity of the settlement joint 12.
[0024] In order to make the copper sheet 20 more tightly combined with the side wall 10 or the bottom wall 11, in the present application, the part of the copper sheet 20 arranged in the side wall 10 or the bottom wall 11 is welded with a baffle on the side, which can effectively prevent the copper sheet 20 from loosening or shifting due to sedimentation or temperature expansion and contraction deformation, thereby improving the safety and reliability of the copper sheet 20.
[0025] Preferably, a plurality of grooves are densely arranged on the seam wall of the settlement seam 12. The design of these grooves helps to increase the surface area of the settlement seam 12, improves the adhesion with the asphalt filling layer 24, the asphalt felt layer 21, the polymer compound layer 22 and the waterproof and anti-corrosion layer 23. It can also effectively enhance the mechanical anchoring effect between the settlement seam 12 and each material layer, further consolidating the sealing and durability of the settlement seam 12.
[0026] Preferably, the width of the copper sheet 20 cast in the side wall 10 or the bottom wall 11 on both sides of the settlement joint 12 is 1 to 3 times the width of the expansion joint. Since the copper sheet 20 is relatively wide, its contact area with the side wall 10 or the bottom wall 11 is correspondingly increased, thereby improving the connection strength and integrity of the copper sheet 20 and the surrounding structure, so that when the structure settles and the temperature expands and deforms, the settlement joint 12 can better withstand the stress generated thereby, reducing the risk of structural cracking or damage. Secondly, since the copper sheet 20 itself has a certain flexibility, the wider copper sheet 20 can disperse the stress more evenly when subjected to external force, reducing the stress concentration phenomenon, which enables the settlement joint 12 to maintain better integrity and sealing when facing deformation such as foundation settlement, preventing sewage leakage or other structural problems. Preferably, the thickness of the copper sheet 20 is set to 2 to 4 mm.
[0027] See also Figure 2In order to optimize the anti-penetration, anti-corrosion and antibacterial effects of the non-domestic sewage regulating tank, this application adopts a series of carefully designed protective layers to ensure the stability and durability of the internal structure of the regulating tank. Specifically, the inner surfaces of the side wall 10 and the bottom wall 11 are provided with a mortar waterproof layer 16, an antibacterial coating 17, a first anti-corrosion layer 18, a second anti-corrosion layer 19 and a third anti-corrosion layer 110 from the inside to the outside. More specifically, the mortar waterproofing adopts a composite layer of waterproof mortar and polymer cement waterproof coating with a thickness ratio of 8:1, which can effectively prevent the penetration of water, protect the internal structure of the regulating tank from water erosion, and improve the overall waterproof performance. The antibacterial coating 17 adopts a water-based antibacterial glaze paint antibacterial coating 17, which has good antibacterial properties, can effectively inhibit the growth of bacteria and mold, and keep the internal environment of the regulating tank clean and sanitary. The first anti-corrosion layer 18 adopts a high-permeability epoxy resin closed primer anti-corrosion layer, which has excellent permeability and sealing properties, can effectively prevent the corrosion of the internal structure of the regulating tank by chemicals in the sewage, and improves the corrosion resistance of the regulating tank. The second anti-corrosion layer 19 adopts a solvent-free epoxy resin paint anti-corrosion layer, which has high chemical resistance and corrosion resistance, can effectively resist chemical corrosion in sewage, and further improves the corrosion resistance of the regulating tank. The third anti-corrosion layer 110 adopts an epoxy resin magnetic paint anti-corrosion layer, which has good adhesion and corrosion resistance and wear resistance, can effectively protect the internal structure of the regulating tank from erosion by the external environment, and extend the service life of the regulating tank.
[0028] Preferably, two liquid level sensors 111 of different heights are provided on the side wall 10, and the two liquid level sensors 111 are electrically connected to a controller arranged outside the regulating tank body 1. When the liquid level in the regulating tank body 1 is higher than the liquid level sensor 111 located at a high position, the liquid level sensor 111 can send the liquid level data to the controller, and the controller controls the liquid outlet pump to start and opens the liquid outlet regulating valve according to the program preset by the controller, so that the sewage is discharged into the subsequent biochemical treatment tank for the next process treatment, avoiding the overflow and leakage caused by overflow; when the liquid level is between the two liquid level sensors 111, the controller controls the opening of the liquid outlet regulating valve according to the signals of the two liquid level sensors 111 to keep the liquid level in the regulating tank body 1 relatively stable; when the liquid level is lower than the liquid level sensor 111 located at the bottom, the liquid level sensor 111 at the bottom can send the liquid level data to the controller, and the controller controls the closing of the liquid outlet regulating valve and the liquid outlet pump.
[0029] In order to better ensure that the sewage can be fully mixed with the medicine during the adjustment process, so as to achieve a better treatment effect. In the present application, a plurality of mounting frames 30 are arranged on the top of the regulating tank body 1, and a stirring motor 31 is arranged on the mounting frame 30. The output end of the stirring motor 31 is connected to a stirring shaft 32 and extends into the regulating tank body 1. Through the coordinated work of multiple stirring motors 31, a stronger stirring force can be formed, so that the sewage and medicine in the pool are mixed more evenly, which helps to speed up the chemical reaction speed and improve the treatment efficiency.
[0030] In order to prevent the sludge deposited at the bottom from piling up, an aeration device is provided at the bottom of the regulating tank body 1, which can provide continuous airflow to the bottom of the regulating tank, which helps to break the sedimentation state of the sludge and prevent it from over-accumulating. Through the stirring action of the airflow, the sludge particles can be suspended and better mixed with the liquid in the tank, thereby reducing the accumulation of sludge at the bottom. In the present application, a plurality of mud discharge ports are provided at the bottom of the side of the regulating tank body 1, and an electronic valve is provided at the mud discharge port and connected to a mud suction pump to discharge the sludge during mud discharge.
[0031] When the non-domestic sewage regulating tank provided by the present patent is constructed, the formwork is first installed, and then the steel bars 25 are installed. During the installation of the steel bars 25, the copper sheet 20 is welded and installed at the same time, and then the waterproof concrete is poured. After the pouring is completed, the formwork is installed at the settlement joint 12, and then the asphalt filling layer 24 is filled on the outside. The side of the settlement joint 12 close to the inner side of the regulating tank body 1 is successively provided with an asphalt felt layer 21, a polymer compound layer 22 and a corrosion-resistant layer. After the materials in the settlement joint 12 are made, a mortar waterproof layer 16, an antibacterial coating 17, a first anti-corrosion layer 18, a second anti-corrosion layer 19 and a third anti-corrosion layer 110 are successively applied in the regulating tank body 1. At the same time, a mounting frame 30 is arranged on the top of the regulating tank body 1, and a stirring motor 31 is installed, and an aeration device is arranged in the regulating tank body 1.
[0032] The utility model provides a non-domestic sewage regulating pool, which includes a copper sheet 20, an asphalt felt layer 21, a polymer compound layer 22 and a corrosion-resistant layer arranged in a settlement joint 12, which effectively prevents leakage problems in the sewage regulating pool, maintains the sealing of the system, reduces the risk of environmental pollution and waste of resources, and the corrosion-resistant layer avoids the corrosion of sewage to a certain extent, thereby extending the service life of the regulating pool. Secondly, the arrangement of the copper sheet 20 with a V-shaped or wavy shape in the middle part in the settlement joint 12 not only provides a flexible structure, but also when the foundation settles, the V-shaped or wavy part can show a certain degree of expansion and contraction ductility, which enables the copper sheet 20 to better adapt to the change of the foundation, thereby reducing the risk of stress concentration and structural cracking caused by foundation settlement. Even in the case of foundation settlement, the setting of the settlement joint 12 can remain relatively intact, effectively preventing the leakage problem of the sewage regulating pool, and maintaining the stability and safety of the system. Therefore, the non-domestic sewage regulating pool effectively prevents leakage problems, maintains the sealing of the system, and reduces the risk of environmental pollution and waste of resources.
[0033] The above disclosures are only several preferred embodiments of the present invention, which certainly cannot be used to limit the scope of rights of the present invention.
