Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to an auxiliary device for deep bed denitrification biological filter. Background Technology

[0002] Wastewater treatment refers to the process of treating wastewater generated from domestic and industrial sources through a series of physical, chemical, and biological methods to remove pollutants and make it meet discharge standards or reclaimable water quality requirements. Among them, denitrification filters are a type of biological filter with denitrification and nitrogen removal functions. They are developed based on traditional biological filters and have nitrate removal effects. At the same time, they also use biological physiological processes to purify the wastewater.

[0003] The prior art CN215161386U describes a deep bed denitrification biological filter device, which includes a filter tank. A support frame is fixedly connected to the bottom of the filter tank. By using the filter tank, support frame, filter plate, filter head, first opening, transmission mechanism, rotating handle, movable groove, first slider, first sliding groove, clamping mechanism, transmission rod, clamping block, transmission block, transmission groove, sealing ring, toothed groove, second opening, limiting groove, rubber pad and fixing block in combination, it has the advantage of easy replacement.

[0004] However, when the quality and quantity of influent water fluctuate significantly, or when the biological filter malfunctions, traditional treatment systems often struggle to guarantee stable and continuous wastewater treatment results. Utility Model Content

[0005] The purpose of this invention is to provide an auxiliary bypass device for deep bed denitrification biological filters, which aims to solve the technical problem that traditional treatment systems often cannot guarantee stable and continuous sewage treatment effects when the influent water quality and quantity fluctuate significantly or when the biological filter malfunctions.

[0006] To achieve the above objectives, this utility model employs an auxiliary bypass device for a deep-bed denitrification biological filter, comprising an inlet pipe, an outlet pipe, and a filter body. A first solenoid valve is installed at the outlet end of the inlet pipe. A filter plate is installed in the middle of the filter body, and a discharge group is installed on the outer side of the filter body. The discharge group includes a bypass pipe and two outlet pipes. A second solenoid valve is installed on the bypass pipe, and a third solenoid valve is installed on the outlet pipes. The bypass pipe and the two outlet pipes are connected by a rectangular circular pipe. A branch pipe is connected above the rectangular circular pipe, and a fourth solenoid valve is installed on the branch pipe. An outlet pipe is installed below the rectangular circular pipe. The branch pipe is connected to the inlet pipe and located on the inlet pipe, and also above the first solenoid valve. The inlet pipe is located above the filter body, and the outlet pipe is connected to the outlet pipe and located on the outlet pipe, with the outlet pipe located below the filter body.

[0007] The filter plate has a post-filtration chamber between its lower end face and the filter tank body, and the inner wall of the post-filtration chamber is equipped with multiple first water quality monitoring instruments. The filter plate has a pre-filtration chamber between its upper end face and the filter tank body, and the inner wall of the pre-filtration chamber is equipped with a water level detector and multiple second water quality monitoring instruments.

[0008] There are four discharge groups, and the four discharge groups are arranged in a cross-shaped symmetrical arrangement on the outside of the filter tank body.

[0009] The filter chamber has a flow guide block at its inner bottom, and the outer side of the flow guide block has multiple flow guide slopes, with the lowest end of the flow guide slopes facing the two water outlet pipes.

[0010] The bypass water pipe and the two outlet water pipes are all installed at an angle on the outside of the filter tank body, and the bypass water pipe extends into the pre-filter chamber, while the two outlet water pipes extend into the post-filter chamber.

[0011] This utility model discloses an auxiliary bypass device for a deep-bed denitrification biological filter, comprising an inlet pipe, an outlet pipe, and a filter body. A first solenoid valve is installed at the outlet end of the inlet pipe. A filter plate is installed in the middle of the filter body, and a discharge group is installed on the outer side of the filter body. The discharge group includes a bypass pipe and two outlet pipes. A second solenoid valve is installed on the bypass pipe, and a third solenoid valve is installed on each outlet pipe. The bypass pipe and the two outlet pipes are connected by a rectangular circular pipe. A branch pipe is connected above the rectangular circular pipe, and a fourth solenoid valve is installed on the branch pipe. An outlet pipe is installed below the rectangular circular pipe. By configuring the first, second, third, and fourth solenoid valves, and the bypass device, the filter body can achieve the desired effect. The bypass pipe and outlet pipe, among other structures, can flexibly adjust the water flow path when there are significant fluctuations in the influent water quality and quantity. This allows some or all of the water flow to be guided to the bypass pipe, bypassing some treatment units of the filter tank or directly entering subsequent treatment stages. This prevents the biological filter from experiencing a decrease in treatment efficiency due to excessive load. Furthermore, in the event of a malfunction in the filter tank, this device can serve as an emergency channel, ensuring that wastewater can continue to be treated to a certain extent or be temporarily stored at a suitable location, thus guaranteeing the continuity and stability of the wastewater treatment process. In addition, by installing monitoring equipment such as water quality monitors and water level detectors, the device can monitor water quality and level in real time, providing data support for intelligent control and further improving the efficiency and stability of wastewater treatment.

Detailed Implementation

[0017] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0018] Please see Figures 1 to 3 This utility model provides an auxiliary bypass device for a deep-bed denitrification biological filter, including an inlet pipe 1, an outlet pipe 2, and a filter body 3. A first solenoid valve 4 is installed at the outlet end of the inlet pipe 1. A filter plate 5 is installed in the middle of the filter body 3. A discharge group is installed on the outer side of the filter body 3. The discharge group includes a bypass water pipe 6 and two outlet pipes 7. A second solenoid valve 8 is installed on the bypass water pipe 6, and a third solenoid valve 9 is installed on the outlet pipes 7. A rectangular cable connects the bypass water pipe 6 and the two outlet pipes 7. A rectangular tube 10 is connected to the filter tank body 3. A branch pipe 11 is connected to the top of the rectangular tube 10. A fourth solenoid valve 12 is installed on the branch pipe 11. An outlet pipe 13 is installed below the rectangular tube 10. The branch pipe 11 is connected to the inlet pipe 1 and is located on the inlet pipe 1, and is also located above the first solenoid valve 4. The inlet pipe 1 is located above the filter tank body 3. The outlet pipe 13 is connected to the drain pipe 2 and is located on the drain pipe 2, and the drain pipe 2 is located below the filter tank body 3.

[0019] In this embodiment, by setting the bypass water pipe 6 and multiple solenoid valves, the water flow can be guided to bypass some of the treatment units of the filter tank body 3 when needed, and directly enter the subsequent treatment stage for processing, thereby coping with fluctuations in water quality and quantity. When the filter tank body 3 malfunctions or needs maintenance, the bypass water pipe 6 can serve as an emergency channel to ensure the continuity of sewage treatment and prevent large amounts of sewage from accumulating at the front end. Furthermore, by adjusting the opening state of the solenoid valves, the water flow rate entering the filter tank body 3 and the bypass water flow rate can be controlled, thereby cooperating with the carbon source dosing system to optimize the treatment effect.

[0020] Furthermore, a post-filtration chamber 14 is provided between the lower end face of the filter plate 5 and the filter tank body 3, and a plurality of first water quality monitoring instruments 15 are provided on the inner wall of the post-filtration chamber 14. A pre-filtration chamber 16 is provided between the upper end face of the filter plate 5 and the filter tank body 3, and a water level detector and a plurality of second water quality monitoring instruments 17 are provided on the inner wall of the pre-filtration chamber 16.

[0021] In this embodiment, by setting up a water quality monitoring instrument, the water quality before and after filtration can be monitored in real time, providing a basis for adjusting the treatment parameters. The water level detector monitors the water level in the pre-filtration chamber 16, which can promptly detect and handle possible system faults, such as blockage or overload. Furthermore, based on the water quality monitoring data, the ratio of excess flow to flow entering the filter tank body 3 can be adjusted more precisely, thereby improving the treatment accuracy and efficiency.

[0022] Furthermore, there are four discharge groups, and the four discharge groups are respectively arranged in a cross-shaped symmetrical arrangement on the outside of the filter body 3.

[0023] In this embodiment, by increasing the number of discharge groups and arranging them in a cross-shaped symmetrical configuration, the water flow can be distributed more evenly, improving the system's processing capacity. Furthermore, when multiple discharge groups are working simultaneously, even if one or more of them malfunction, the other discharge groups can still function normally, thereby ensuring the system's stability.

[0024] Furthermore, a flow guide block 18 is provided at the bottom of the filter chamber 14, and the outer side of the flow guide block 18 has multiple flow guide slopes 19, with the lowest end of the flow guide slopes 19 facing the two water outlet pipes 7.

[0025] In this embodiment, by setting the guide block 18 and the guide slope 19, the water flow in the filter chamber 14 can be guided to flow more evenly to the outlet pipe 7, avoiding local water accumulation and blockage. After optimizing the water flow distribution, the processing capacity of the filter tank body 3 can be utilized more effectively, thereby improving the processing efficiency.

[0026] Furthermore, the bypass water pipe 6 and the two outlet water pipes 7 are both arranged at an angle on the outside of the filter tank body 3, and the bypass water pipe 6 extends into the pre-filter chamber 16, and the two outlet water pipes 7 extend into the post-filter chamber 14.

[0027] In this embodiment, by tilting the water pipe, the resistance of the water flow in the pipe can be reduced, thereby improving the smoothness of the water flow and the processing efficiency.

[0028] In this invention, when wastewater enters the device through the inlet pipe 1, it first passes through the control of the first solenoid valve 4, and then flows through the filter plate 5 of the filter tank body 3 for preliminary treatment. The treated water is discharged into the discharge pipe 2 through the outlet pipe 7 and the outlet pipe 13. At this time, the water level detector and the second water quality monitor 17 in the pre-filtration chamber 16 monitor the water quality and water level in real time. If the influent water quality or quantity fluctuates, or if the filter tank needs maintenance or backwashing, the opening state of the second solenoid valve 8 and the third solenoid valve 9 can be adjusted to allow part or all of the water to bypass the filter plate 5 through the bypass pipe 6 and directly enter the subsequent treatment. In addition to the main treatment process, the wastewater in the inlet pipe 1 can also be transported to the subsequent treatment stages through the branch pipe 11. Furthermore, the first water quality monitor 15 in the post-filtration chamber 14 continuously monitors the water quality to ensure that the effluent quality meets the standards. The four discharge groups are arranged in a cross-shaped symmetrical configuration, which optimizes the water flow distribution and improves the treatment capacity. The guide block 18 at the bottom of the post-filtration chamber 14 further guides the water flow to the outlet pipe 7 evenly, avoiding local blockage. The bypass pipe 6 and the outlet pipe 7 are inclined, which reduces water flow resistance and improves treatment efficiency. In summary, this device can flexibly cope with various fluctuations in water quality and quantity, ensure the stable operation of the wastewater treatment system, and optimize the treatment effect.

[0029] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
