Description

Technical Field

[0001] This application relates to the field of wastewater treatment technology, and specifically discloses a regulating device for wastewater treatment for ecological and environmental protection. Background Technology

[0002] The ecological environment refers to the total quantity and quality of water resources, land resources, biological resources, and climate resources that affect human survival and development. It is a complex ecosystem that is related to the sustainable development of society and economy.

[0003] With societal progress, large amounts of wastewater are typically generated during urban life and industrial production. Currently, all wastewater requires treatment at wastewater treatment plants to meet the water quality requirements for discharge into water bodies or for reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, healthcare, and catering, and is increasingly becoming a part of everyday life for ordinary people.

[0004] In the process of treating sewage in sewage treatment plants, one step is to use sedimentation tanks to separate the sludge produced during sewage treatment. Currently, during the sedimentation process, existing sedimentation tanks are usually cleaned by using external equipment such as scrapers to scrape the sludge to the center after sedimentation. This method may result in inconsistencies in the sedimentation conditions of the sewage before and after sludge removal, thus affecting the assessment of the sewage sedimentation treatment effect when the sewage enters the next sludge treatment unit. Therefore, the inventors have provided an adjustment device for sewage treatment in ecological environmental protection to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to solve the problem that traditional sewage treatment sedimentation tanks can easily affect the subsequent judgment of settled sewage during use.

[0006] To achieve the above objectives, the basic solution of the present invention provides a regulating device for wastewater treatment in ecological environment protection, comprising an overflow tank and an inlet tank arranged in sequence. The bottom of the inlet tank is connected to a first sedimentation tank, and the first sedimentation tank is provided with a sedimentation channel penetrating the inlet tank. The bottom of the overflow tank is connected to a second sedimentation tank surrounding the sedimentation channel. The outside of the overflow tank is provided with a drain channel for discharging sedimented water. The bottom of the overflow tank is evenly distributed and rotatably provided with a plurality of functional plates for pushing sediments to the second sedimentation tank. The inlet tank is provided with a plurality of inlet pipes for controlling the swing of the functional plates.

[0007] The principle and effect of this basic scheme are as follows: 1. Wastewater requiring sedimentation and sludge separation is injected into the inlet tank through the inlet pipe and then flows into the first sedimentation tank, where part of the sludge sedimentation can be completed.

[0008] 2. During the re-sedimentation process of the sewage in the first sedimentation tank, it will be subjected to the pressure of the continuously entering sewage and enter the overflow tank through the sedimentation channel. During this process, most of the sludge will settle in the first sedimentation tank, and only a small part of the lighter sludge will enter the overflow tank for sedimentation.

[0009] 3. The sewage entering the overflow tank first spreads outward from the center. At this time, a large portion of the sludge will settle in the second sedimentation tank, with only a small portion falling onto the inner bottom surface of the overflow tank. Due to the cooperation of the inlet pipe and the functional plate, the sludge about to fall onto the inner bottom surface of the overflow tank will be directly pushed to the second sedimentation tank. In this process, as long as the water intake is continuous, the sewage in the overflow tank is always in a dynamic process of collecting sludge. Therefore, as long as the sludge content in the sewage does not change significantly, the sewage indicators will basically remain at a certain level during subsequent inspections. The sludge collected in the first and second sedimentation tanks in the center can be discharged in the same manner as in a traditional sedimentation tank.

[0010] 4. By radiating outwards from the center and upwards from the bottom, the sedimentation quality of sewage sludge can be improved efficiently, and the sedimentation process can be completed more effectively.

[0011] Compared with existing technologies, this invention, in the process of wastewater sludge sedimentation, firstly and directly settles the sludge in the first sedimentation tank. Secondly, through tiered sedimentation, it effectively reduces the impact of sludge removal on the settled wastewater, thereby effectively improving the efficiency and quality of wastewater treatment in the process of environmental protection. Furthermore, through the water intake step, it can actively push sludge that is not located in the center to the center, thereby ensuring dynamic cleaning of sludge and effectively ensuring the consistency of wastewater discharge indicators. The operation is simple, highly feasible, and easy to promote and use in this field.

[0012] Furthermore, the bottom of the water inlet tank is provided with a water distribution tank that communicates with the water inlet conduit, and the water distribution tank is provided with a water inlet channel. This facilitates the supply of water to several water inlet conduits using one water inlet.

[0013] Furthermore, the diameter of the inlet channel is smaller than that of the sedimentation channel. This reduces the water pressure entering the sedimentation channel, thereby slowing down the water flow rate.

[0014] Furthermore, the top of the sedimentation channel is equipped with a cover to prevent water from flowing straight out. This effectively prevents water from flowing vertically towards the surface of the overflow tank, thereby improving the sedimentation effect of sludge.

[0015] Furthermore, a first observation channel is provided outside the water diversion channel, and a second observation channel is provided between the first observation channel and the cover plate. This facilitates the sampling and observation work of sewage treatment personnel.

[0016] Furthermore, each of the functional plates located on one side of the overflow tank is equipped with a water-blocking plate. A first stop rod is fixedly connected to the side of the functional plate away from the second sedimentation tank to increase the resistance of the water-blocking plate, and a second stop rod is fixedly connected to the side of the functional plate closer to the second sedimentation tank to reduce the resistance of the water-blocking plate. This facilitates improved sludge agitation.

[0017] Furthermore, a return spring is fixed to one side of the functional plate located in the water inlet tank, and controlled valves are installed inside the water inlet pipes. This facilitates the normal reciprocating movement of the functional plate by the flow of water.

[0018] Furthermore, the outlet of each water inlet pipe is equipped with a conical pressure nozzle. This increases the water flow velocity at the bottom of the water inlet tank, facilitating the operation of the functional plate and reducing sludge sedimentation within the tank.

[0019] Furthermore, the first sedimentation tank is provided with a sludge discharge chamber for connecting to the second sedimentation tank, and both the sludge discharge chamber and the first sedimentation tank are connected to a sludge removal device. This facilitates the discharge of sludge from the second sedimentation tank together with the sludge from the first sedimentation tank, reducing the need for sludge removal equipment.

Detailed Implementation

[0022] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0023] The reference numerals in the accompanying drawings include: first observation channel 1, second observation channel 2, cover plate 3, functional plate 4, water blocking plate 5, overflow trough 6, water inlet trough 7, mounting bracket 8, drain pipe 9, second stop bar 10, first stop bar 11, pull-back spring 12, first sedimentation tank 13, water distribution trough 14, water inlet channel 15, drain chamber 16, second sedimentation tank 17, and water inlet conduit 18.

[0024] Implementation, for example Figure 1 As shown, the device includes an overflow tank 6 and an inlet tank 7 stacked from top to bottom. An installation bracket 8 for installing the device is provided outside the overflow tank 6 and the inlet tank 7. A water guide channel for draining sedimented water is installed on the top of the outer side of the overflow tank 6.

[0025] like Figure 5 and Figure 6 As shown, a first sedimentation tank 13 is installed at the center of the bottom of the inlet tank 7. The highest surface of the first sedimentation tank 13 coincides with the lowest surface of the inlet tank 7. A sedimentation channel penetrating the inlet tank 7 is provided in the first sedimentation tank 13. The lower end of the sedimentation channel is located in the middle of the first sedimentation tank 13, and the upper end of the sedimentation channel is located in the middle of the overflow tank 6. Several support rods are welded to the top of the sedimentation channel. A cover plate 3 to prevent water from flowing directly out is welded to the upper end of the support rods. A second sedimentation tank 17 is installed at the bottom of the overflow tank 6, surrounding the outer wall of the sedimentation channel. The highest surface of the second sedimentation tank 17 coincides with the lowest surface of the overflow tank 6. A sludge removal device is provided in the first sedimentation tank 13 to connect to the second sedimentation tank 17. A sludge removal device is connected between the sludge removal device and the first sedimentation tank 13. The sludge removal device is connected to the sludge removal device through a sludge removal pipe 9.

[0026] like Figure 1 , Figure 5 and Figure 6 As shown, a first observation channel 1 is provided outside the water diversion channel, and a second observation channel 2 is provided between the first observation channel 1 and the cover plate 3, as shown. Figure 3 , Figure 5 and Figure 6 As shown, six functional plates 4 are evenly distributed and rotatably installed at the bottom of the overflow tank 6 to direct sediment to the second sedimentation tank 17. Figure 2As shown, the functional plate 4 is rotatably equipped with a water-blocking plate 5 on one side of the overflow tank 6. A first stop bar 11 is fixedly connected to the side of the functional plate 4 away from the second sedimentation tank 17 to increase the resistance of the water-blocking plate 5. A second stop bar 10 is fixedly connected to the side of the functional plate 4 closer to the second sedimentation tank 17 to reduce the resistance of the water-blocking plate 5. When the water-blocking plate 5 is pressed against the first stop bar, it is completely parallel to the functional plate 4, thus increasing the resistance. When the water-blocking plate 5 is pressed against the second stop bar, it forms a certain angle with the functional plate 4, thus reducing the contact area and reducing the resistance. A return spring 12 is installed on the side of the functional plate 4 located in the inlet tank 7. Figure 5 and Figure 6 As shown, the water inlet tank 7 is equipped with six water inlet pipes 18 for controlling the swing of the function board 4. Each water inlet pipe 18 is equipped with a controlled valve, and each water outlet of the water inlet pipe 18 is equipped with a conical pressure nozzle.

[0027] like Figure 4 , Figure 5 and Figure 6 A water distribution tank 14 connected to the water inlet pipe 18 is installed at the bottom of the water inlet tank 7. A water inlet channel 15 is connected to the water distribution tank 14. The diameter of the water inlet channel 15 is smaller than that of the sedimentation channel.

[0028] Before use, install this device in the designated location of the sewage treatment plant using the mounting bracket 8. Then connect the sewage pipe 9 to the sludge removal equipment, the water inlet channel 15 to the outlet of the previous unit, and the water guide channel to the outlet of the next channel. Several units of this device can be connected in series as needed, and then it can be put into use.

[0029] First, the wastewater requiring sludge separation enters the distribution tank 14 through the inlet channel 15, flows into the inlet tank 7 through the inlet pipe 18, and then flows into the first sedimentation tank 13, completing the first sludge sedimentation. Then, during the sedimentation process in the first sedimentation tank 13, the wastewater is pressured by the continuously flowing wastewater and enters the overflow tank 6 through the sedimentation channel. During this process, most of the sludge settles in the first sedimentation tank 13, and only a small portion of the lighter sludge enters the overflow tank 6 for sedimentation. Furthermore, the wastewater entering the overflow tank 6 is blocked by the cover plate 3 and then diffuses outwards from the center, from bottom to top. At this point, a large portion of the sludge settles in the second sedimentation tank 17, with only a small portion settling on the inner bottom surface of the overflow tank 6. Since the controlled valve in the inlet pipe 18 is controlled by the wastewater treatment control center, it is opened and closed intermittently, and then... With the help of the traction spring, the reciprocating motion of the functional plate 4 can be completed. The sludge falling on the inner bottom surface of the overflow tank 6 will be directly pushed towards the second sedimentation tank 17. The water-blocking plate 5 set on the functional plate 4 can be completely parallel to the functional plate 4 when it is close to the first stop bar. At this time, the force-bearing area increases, thereby increasing the resistance. When the water-blocking plate 5 is close to the second stop bar, the water-blocking plate 5 forms a certain angle with the functional plate 4, thereby reducing the force-bearing area and reducing the resistance. In this way, the reciprocating swing can be effectively performed. During this process, as long as the water intake is continuous, the sewage in the overflow tank 6 is always in a dynamic process of collecting sludge. Therefore, as long as the sludge content in the sewage does not change much, the sewage indicators will basically remain at a certain level during subsequent inspections. The sludge collected in the center of the first sedimentation tank 13 and the second sedimentation tank 17 can be discharged in the same way as in a traditional sedimentation tank.

[0030] In the process of wastewater sludge sedimentation, the present invention first actively and directly settles the sludge in the first sedimentation tank 13. Then, through tiered sedimentation, the impact of sludge removal on the settled wastewater is effectively reduced, thereby effectively improving the efficiency and quality of wastewater treatment in the process of environmental protection. Furthermore, through the water intake step, sludge that is not located in the center can be actively pushed to the center, thereby ensuring dynamic cleaning of sludge and effectively ensuring the consistency of wastewater discharge indicators. The invention is simple to operate, highly feasible, and easy to promote and use in the field.
