Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to an automated cleaning device for the filter media interception screen in an MBBR process. Background Technology

[0002] Moving Bed Biofilm Reactor (MBBR) is a mature wastewater biochemical treatment technology internationally. Since the first MBBR plant was built in 1989, thousands of municipal and industrial wastewater treatment facilities have been constructed worldwide, achieving excellent results. This process uses suspended carriers to provide a growth medium for microorganisms, achieving efficient wastewater treatment through the full fluidization of the suspended carriers. This process fully incorporates the advantages of biological contact oxidation and biological fluidized beds, overcoming their disadvantages such as low mass transfer efficiency, poor treatment efficiency, and high fluidization kinetics. It utilizes the basic principles of biofilm technology and fully leverages the advantages of activated sludge processes, achieving activated sludge operation of the biofilm process. With the gradual application of MBBR technology in wastewater treatment, long-term operation has revealed that if the packing screen in the MBBR process tank is not cleaned for an extended period, sludge flocs will adhere to its surface. The growth of microorganisms in the sludge flocs will gradually clog the screen, causing waterlogging in the effluent area of ​​the process tank. If this problem is not addressed promptly, the compliant operation of the wastewater treatment plant will be affected. Therefore, timely and effective cleaning of the MBBR process packing screen is necessary.

[0003] In current technologies, cleaning the filter media in MBBR processes mainly relies on wastewater treatment plant maintenance personnel manually cleaning the exposed portion of the filter media using long-handled brushes; or increasing the terminal aeration rate to reduce the accumulation of filter media and the adhesion of sludge flocs in the filter media area through airflow disturbance. Existing cleaning methods suffer from problems such as incomplete cleaning, long processing times, and high labor costs. Summary of the Invention

[0004] This invention addresses the shortcomings of existing technologies by providing an automated cleaning device for the MBBR process packing interceptor screen. Through automated equipment, it achieves efficient and thorough cleaning, ensuring unobstructed effluent from the MBBR process tank and guaranteeing the stable and compliant operation of the wastewater treatment plant.

[0005] To achieve the above objectives, this utility model designs an automated cleaning device for the MBBR process packing interception net, including a process tank, an interception net at the outlet of the process tank, a guide rail on the walkway of the process tank, a roller cart on the guide rail, a connecting rod fixed on the roller cart, a roller rotatably mounted on the connecting rod, and the roller rolling on the interception net.

[0006] Preferably, a roller motor is provided at the end of the connecting rod away from the roller carriage, and a roller is mounted on the shaft of the roller motor.

[0007] Preferably, roller sensors are provided at both ends of the guide rail.

[0008] Preferably, the roller vehicle includes a body, rollers are provided on both sides of the body, and a connecting rod is fixed to the top of the body.

[0009] Preferably, the roller is a polyester roller.

[0010] Preferably, the height of the roller is equal to the height of the interception net.

[0011] Preferably, the connecting rod is inverted U-shaped.

[0012] Preferably, an intelligent control cabinet is provided next to the process pool, and the signal output terminal of the intelligent control cabinet is connected to the signal receiving terminal of the roller cart and the roller motor; the signal output terminal of the roller cart sensor is connected to the signal receiving terminal of the intelligent control cabinet.

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] Example 1

[0031] like Figure 1The automated cleaning device for the MBBR process packing screen shown includes a process tank, an intercepting screen at the outlet of the process tank, a guide rail 1 on the walkway of the process tank, and roller trolley sensors 11 at both ends of the guide rail 1. A roller trolley 2 is mounted on the guide rail, the roller trolley 2 including a body 21, rollers 22 on both sides of the body 21, and a connecting rod 3 fixed to the top of the body 21. The connecting rod 3 is inverted U-shaped. A roller motor 41 is mounted on the end of the connecting rod 3 away from the roller trolley 2, and a roller 4 is mounted on the shaft of the roller motor 41. The roller 4 rolls on the intercepting screen. The roller 4 is a polyester roller. The height of the roller 4 is equal to the height of the intercepting screen.

[0032] Next to the process pool, there is an intelligent control cabinet 5. The signal output terminal of the intelligent control cabinet 5 is connected to the signal receiving terminal of the roller cart 2 and the roller motor 41; the signal output terminal of the roller cart sensor 11 is connected to the signal receiving terminal of the intelligent control cabinet 5.

[0033] The following describes the technological process of this utility model:

[0034] Based on daily process inspections, wastewater treatment plant maintenance personnel check the effluent interceptor screen of the MBBR process tank for any deposits that might obstruct effluent flow. If stagnant water or prolonged accumulation of packing material is found in the effluent area, maintenance personnel activate the cleaning device via the intelligent control cabinet 5. The intelligent control cabinet 5 sends a signal, activating the motor of the roller cart 2, which moves the roller cart 2 along the guide rail 1. The roller cart sensor 11 monitors the position of the roller cart 2 in real time, ensuring its safe operation on the guide rail 1. When the roller cart 2 approaches the end of the guide rail 1, the sensor 11 sends a signal, and the intelligent control cabinet 5 controls the roller cart 2 to stop and move in the opposite direction. Simultaneously, the intelligent control cabinet 5 drives the drum motor 41, which in turn drives the drum 4 to roll on the interceptor screen. The drum 4 removes the deposits from the interceptor screen through physical friction.

[0035] When maintenance personnel observe that there are stubborn attachments in some areas of the interception net, the intelligent control cabinet 5 controls the roller cart 2 to move to the designated position through the roller cart sensor 11, and the intelligent control cabinet 5 drives the roller motor 41 to clean the designated position.

[0036] Example 2

[0037] The structure of Example 2 is largely the same as that of Example 1, except that the intelligent control cabinet 5 is reduced and manual control is adopted, which saves the manufacturing cost of the automated cleaning device for the MBBR process packing interception net.

[0038] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be included within the protection scope of this application.
