Description

Technical Field

[0001] This application relates to the field of wastewater treatment equipment technology, specifically a modular combined wastewater biochemical treatment equipment. Background Technology

[0002] Existing wastewater biochemical treatment equipment is mainly used for the biochemical treatment of wastewater. Through the metabolic action of microorganisms, organic pollutants in wastewater are decomposed and transformed into harmless substances, thereby purifying the wastewater for subsequent discharge or reuse.

[0003] However, traditional equipment typically introduces chemicals uniformly into the treatment tank, making it difficult to precisely deliver chemicals to specific areas based on the characteristics and treatment requirements of different sections of the wastewater. For example, the concentration and composition of pollutants in wastewater may vary at different locations within the treatment tank, and uniformly introducing chemicals cannot achieve efficient treatment, resulting in poor treatment effects and low treatment efficiency.

[0004] Moreover, traditional wastewater biological treatment equipment struggles to precisely treat wastewater at different depths within the treatment tank. This is because the water quality (such as dissolved oxygen content and pollutant concentration) varies at different depths within the treatment tank, and existing equipment often uses fixed pipelines to introduce chemical agents. This makes it difficult to deliver chemical agents to different depths according to actual needs, resulting in inadequate wastewater treatment.

[0005] Therefore, it is necessary to provide a modular and combined wastewater biochemical treatment equipment to solve the above problems.

[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0007] The purpose of this invention is to provide a modular combined wastewater biochemical treatment device to solve the problems mentioned in the background art.

[0008] The technical solution adopted by this application to solve its technical problem is:

[0009] A modular combined wastewater biochemical treatment device includes a wastewater tank to be treated, a wastewater treatment tank, and a sedimentation tank. The wastewater to be treated is pumped into the wastewater treatment tank by a pumping device. The wastewater treatment tank is pumped into the sedimentation tank by an extraction device. A chemical agent introduction device is also included, which introduces wastewater treatment chemicals into the wastewater treatment tank through an introduction pipe.

[0010] The sewage treatment tank is equipped with a main pipe, and the inlet pipe is connected to the main pipe. Multiple connecting components are fixedly connected to the side wall of the main pipe. Any one of the multiple connecting components is fixedly installed to the docking component in a plug-in manner. A branch pipe is fixedly installed at the top of the docking component, and retractable branch pipes are respectively connected to both sides of the branch pipe.

[0011] The interior of the sewage treatment tank is divided into two sewage treatment zones by a partition, and the branch pipes are respectively placed in the two sewage treatment zones.

[0012] Preferably, the connecting assembly includes a connecting block, a first spring, and a locking block. The connecting block is fixedly connected to the side wall of the main pipe. A slot is formed through the top surface of the connecting block, and an inlet groove is formed on the bottom surface of the connecting block. The slot and the inlet groove are mated together for installation.

[0013] The docking assembly includes an outlet tube, the top end of which is docked with the side wall of the branch tube, a slot is provided on the bottom side wall of the outlet tube, a clearance groove is provided inside the connecting block, the first spring is placed in the clearance groove, and the slot is slidably installed in the clearance groove toward the slot.

[0014] When the outlet tube is inserted into the slot, the end of the card block engages in the slot.

[0015] Preferably, the connecting assembly further includes a plug and a second spring, a water groove is provided at the bottom of the connecting block, one end of the water groove is connected to the slot, the other end of the water groove is connected to the inlet groove, the plug is placed in the water groove, and the second spring is located in the cavity opened at the bottom of the plug.

[0016] The docking assembly also includes a connecting rod and a pressure plate. The bottom surface of the outlet tube is fixedly connected to the connecting rod, and the bottom end of the connecting rod is fixedly connected to the top surface of the pressure plate. When the outlet tube is inserted into the slot, the bottom surface of the pressure plate abuts against the top surface of the plug and compresses the second spring.

[0017] Preferably, a limiting groove is formed at the top edge of the connecting block, and the limiting block is fixedly connected to the side wall of the outlet tube. When the outlet tube is inserted into the slot, the limiting block is inserted into the limiting groove.

[0018] Preferably, the top end of the branch pipe is connected to both sides of the main pipe, a sliding tube is slidably installed inside the branch pipe, a liquid outlet cylinder is fixedly connected to the bottom end of the sliding tube, and a liquid outlet hole is opened on the side wall of the liquid outlet cylinder.

[0019] Preferably, a tapered threaded cylinder is fixedly installed on the bottom surface of the branch pipe, and a notch is opened on the side wall of the tapered threaded cylinder, and an internal threaded sleeve is threadedly connected to the side wall of the tapered threaded cylinder.

[0020] Preferably, a foam discharge chamber is provided on the top of one side of the sewage treatment tank, a foam collection tank is provided below the foam discharge chamber, and the bottom surface of the sewage treatment tank is sloped.

[0021] The beneficial effects of this application are:

[0022] 1. Through modular connecting and docking components, branch pipes and sub-pipes can be selectively installed according to the water quality characteristics of different areas of the sewage treatment tank, so as to accurately introduce chemical agents into specific areas. For example, the amount of agent added can be increased in areas with high pollutant concentrations and reduced in areas with low concentrations. This avoids the waste and insufficient treatment caused by traditional uniform dosing, and achieves efficient treatment of sewage in different areas, significantly improving sewage treatment efficiency and treatment effect.

[0023] 2. Utilizing the retractable sliding pipe, liquid outlet cylinder, and conical threaded cylinder with internal threaded sleeve within the branch pipe, the chemical dosing depth can be flexibly adjusted. Addressing the differences in dissolved oxygen content and pollutant concentration at different depths in the wastewater treatment tank, the chemical is delivered to the appropriate depth, ensuring full contact and reaction between the chemical and the wastewater. This overcomes the shortcomings of traditional fixed pipelines that cannot deliver chemicals to different depths as needed, further enhancing the adequacy and thoroughness of wastewater treatment and effectively improving wastewater treatment quality.

[0041] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0042] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present application.

[0043] Please see Figure 1-5 The embodiments provided by this utility model are as follows:

[0044] like Figure 1As shown, a modular combined wastewater biochemical treatment device includes a wastewater tank 1 to be treated, a wastewater treatment tank 3, and a sedimentation tank 9. Wastewater from the wastewater tank 1 is pumped into the wastewater treatment tank 3 by a pumping device 2. After being treated with chemical agents in the wastewater treatment tank 3, the treated wastewater from the wastewater treatment tank 3 is pumped into the sedimentation tank 9 by an extraction device 8 for sedimentation. A chemical agent introduction device 4 introduces the chemical agents for wastewater treatment into the wastewater treatment tank 3 through an introduction pipe 41. The chemical agent introduction device 4 introduces the chemical agents required for wastewater treatment into the main pipe 5 of the wastewater treatment tank 3 through the introduction pipe 41. The main pipe 5 then distributes the chemical agents to different areas of the wastewater treatment tank 3 through a connecting component 51, a docking component 61, a branch pipe 6, and a branch pipe 62.

[0045] like Figure 2 As shown, in order to facilitate the collection of surface foam in the sewage treatment tank 3, a foam discharge chamber 31 is provided on the top of one side of the sewage treatment tank 3. A foam collection tank 7 is provided below the foam discharge chamber 31. The foam on the surface of the sewage will flow towards the foam discharge chamber 31 under the action of water flow and enter the foam collection tank 7 through the foam discharge chamber 31. The bottom surface of the sewage treatment tank 3 is set with a slope 33 so that the extraction device 8 can discharge the sewage treated by chemical agents in the sewage treatment area into the sedimentation tank 9.

[0046] like Figure 2 and Figure 3 As shown, a main pipe 5 is installed inside the sewage treatment tank 3. An inlet pipe 41 is connected to the main pipe 5. Multiple connecting components 51 are fixedly connected to the side wall of the main pipe 5. Any one of the multiple connecting components 51 is fixedly installed to the docking component 61 by plugging in. A branch pipe 6 is fixedly installed at the top of the docking component 61. Retractable branch pipes 62 are connected to both sides of the branch pipe 6. The interior of the sewage treatment tank 3 is divided into two sewage treatment zones by a partition 32. The branch pipes 62 are placed in the two sewage treatment zones respectively. In order to facilitate the reaction of chemical agents in different areas of the sewage treatment zone according to actual needs, the branch pipes 6 are selectively connected to the connecting components 51 by the docking components 61 in a modular manner to introduce chemical agents into different areas of the two sewage treatment zones. It can accurately introduce chemical agents according to the characteristics and treatment requirements of sewage in different areas, thereby improving the treatment effect.

[0047] Specifically, such as Figure 4As shown, in order to prevent the docking component 61 from being restricted after being plugged into the connecting component 51 and from separating due to water pressure, the connecting component 51 includes a connecting block 511, a first spring 515, and a locking block 516. The connecting block 511 is fixedly connected to the side wall of the main pipe 5. The top surface of the connecting block 511 has a through slot 513, and the bottom surface of the connecting block 511 has an inlet groove 519. The slot 513 and the inlet groove 519 are connected and installed. The docking component 61 includes a discharge pipe 611. The top end of the discharge pipe 611 is connected and installed to the side wall of the branch pipe 6. The bottom side wall of the discharge pipe 611 has a locking groove 613. The inside of the connecting block 511 has a relief groove 514. The first spring 515 is placed in the relief groove 514. The locking block 516 is slidably installed in the relief groove 514 toward the slot 513. When the discharge pipe 611 is inserted into the slot 513, the end of the locking block 516 is locked in the locking groove 613.

[0048] Furthermore, limiting grooves 512 are respectively opened at the top edge of the connecting block 511, and the limiting block 612 is fixedly connected to the side wall of the outlet tube 611. When the outlet tube 611 is inserted into the slot 513, the limiting block 612 is inserted into the limiting groove 512.

[0049] When the outlet pipe 611 of the docking component 61 is inserted into the slot 513, the first spring 515 in the clearance groove 514 inside the connecting block 511 pushes the locking block 516 to engage in the slot 613 on the side wall of the outlet pipe 611. At the same time, the limiting block 612 on the side wall of the outlet pipe 611 is inserted into the limiting groove 512 on the top surface of the connecting block 511 to prevent the docking component 61 and the connecting component 51 from separating due to water pressure. This ensures the stability of the connection between the docking component 61 and the connecting component 51 during the transportation of chemical agents, avoids loosening of the connection due to water pressure and other factors, and ensures that the chemical agents can be smoothly introduced into the sewage treatment area.

[0050] like Figure 4 As shown, when the connecting component 51 is not plugged into the docking component 61, in order to ensure that the connecting component 51 does not leak, the connecting component 51 also includes a plug 517 and a second spring 518. The bottom of the connecting block 511 has a water groove 5110. One end of the water groove 5110 is connected to the slot 513, and the other end of the water groove 5110 is connected to the inlet groove 519. The plug 517 is placed in the water groove 5110, and the second spring 518 is located in the cavity opened at the bottom of the plug 517. The docking component 61 also includes a connecting rod 614 and a pressure plate 615. The bottom surface of the outlet tube 611 is fixedly connected to the connecting rod 614, and the bottom end of the connecting rod 614 is fixedly connected to the top surface of the pressure plate 615. When the outlet tube 611 is inserted into the slot 513, the bottom surface of the pressure plate 615 abuts against the top surface of the plug 517 and compresses the second spring 518.

[0051] When the connecting component 51 is not inserted into the docking component 61, the plug 517 blocks the slot 513 under the action of the second spring 518 to prevent the connecting component 51 from leaking water. When the outlet pipe 611 is inserted into the slot 513, the pressure plate 615 connected to the bottom connecting rod 614 presses down the plug 517, compresses the second spring 518, and makes the water tank 5110 open. The chemical agent can flow from the inlet tank 519 to the water tank 5110 and the outlet pipe 611, and then enter the branch pipe 6. Finally, it is discharged into the sewage treatment area through the branch pipe 62.

[0052] like Figure 5 As shown, in order to introduce chemical agents to different depths in two wastewater treatment zones, the top of the branch pipe 62 is connected to both sides of the main pipe 6. A sliding tube 63 is slidably installed inside the branch pipe 62, and an outlet cylinder 631 is fixedly connected to the bottom end of the sliding tube 63. An outlet hole 632 is opened on the side wall of the outlet cylinder 631. A conical threaded cylinder 64 is fixedly installed on the bottom surface of the main pipe 6, and a notch is opened on the side wall of the conical threaded cylinder 64. An internal threaded sleeve 65 is threadedly connected to the side wall of the conical threaded cylinder 64. By rotating the internal threaded sleeve 65, it can move up and down on the conical threaded cylinder 64, so that the sliding tube 63 can slide in the branch pipe 62 or be clamped and fixed by the conical threaded cylinder 64, thereby adjusting the height of the outlet cylinder 631. This enables the introduction of chemical agents to different depths in the two wastewater treatment zones, further improving the flexibility and accuracy of chemical agent introduction. It can accurately deliver chemical agents to the corresponding positions according to the treatment needs of different depths of wastewater, thereby enhancing the wastewater treatment effect.

[0053] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
