DETAILED DESCRIPTION

[0021] In order to make the purpose, technical scheme and advantages of the embodiments of the application more clear, the technical scheme in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application.

[0022] The technical scheme of the application will be described in detail below with specific embodiments. The following specific embodiments can be combined or replaced according to actual conditions, and the same or similar concepts or processes can not be described in some embodiments.

[0023] As Figures 1 to 4As shown, the present application provides a kind of unpowered microbial filter material water purification device, including cylindrical water purification tank 1, the inside of the water purification tank 1 is divided into the following areas by multiple partitions: sedimentation tank 11, filter tank 12, microbial filler tank 13, and water storage tank 14;Partition layout is used to make sewage sequentially through each area for purification treatment, the water purification tank 1 is equipped with water inlet pipe 2, the water inlet pipe 2 communicates the top of the sedimentation tank 11, the partition between the sedimentation tank 11 and the filter tank 12 is equipped with sediment effluent pipe 21, and the height position is lower than the water inlet pipe 2, the partition between the filter tank 12 and the microbial filler tank 13 is equipped with filter effluent pipe 22, and the height is lower than the sediment effluent pipe 21, the partition between the microbial filler tank 13 and the water storage tank 14 is equipped with purification effluent pipe 23, wherein the microbial filler tank 13 includes filler area 131, the upper portion of the filler area 131 is equipped with filler area water distribution pipe 25 which is parallel to the filter effluent pipe 22 and is connected, the purification effluent pipe 23 is located below the filler area 131, and the water storage tank 14 is further equipped with effluent pipe 24 which is connected to the outside of the tank body.

[0024] By carefully arranging the height difference of water inlet pipe 2 and each stage effluent pipe 24, it is ensured that sewage can pass through each processing area (sedimentation tank 11, filter tank 12, microbial filler tank 13) in a predetermined order, and after each stage of processing is completed, the water body flows into the next processing area through the corresponding water pipe until the final purification; such design helps to gradually reduce the pollutant concentration in the sewage. The water inlet pipe 2 is located at the top of the sedimentation tank 11, ensuring that the sewage first enters the sedimentation tank 11 to remove large particles; the sediment effluent pipe 21 is lower than the water inlet pipe 2, so that the water after preliminary treatment can flow into the first-stage filter tank 121 naturally; the filter effluent pipe 22 is lower, to filter out smaller suspended solids; finally, the purification effluent pipe 23 is located below the microbial filler tank 13, to ensure that clean water after biodegradation is discharged; such gradient design helps to efficiently utilize gravity and promote natural water flow, while ensuring that each processing stage can fully play its purification function; the purified water is finally collected in the water storage tank 14 and connected to the outside of the tank body through the effluent pipe 24; when the water quality meets the discharge standard, it can be safely discharged to natural water body or used as recycled water resources, completing the entire purification process; further, the layout of the microbial filler tank 13 takes into account the needs of microbial activity, the purification effluent pipe 23 is located below the filler area 131, which helps to maintain the microorganisms in the filler area 131 in a suitable environment, facilitating their aerobic or anaerobic reactions to decompose organic matter and other pollutants in the water; the entire system controls water flow through height difference, without the need for additional power drive, which is energy-saving and environmentally friendly, in line with the design concept of unpowered water purification device.

[0025] In order to further optimize the purification effect of the filter tank 12, as shown in the preferred embodiment of the present application, Figure 2 and Figure 3As shown, the filter tank 12 includes a primary filter tank 121 and a secondary filter tank 122, which are provided with a filter tank water distribution pipe 26 connected to the sedimentation effluent pipe 21. After treatment in the sedimentation tank 11, there may still be a certain amount of suspended impurities in the sewage. In the MRS water purification system, the filter tank 12 is divided into two levels, namely the primary filter tank 121 and the secondary filter tank 122, which jointly undertake the task of further purifying suspended impurities in the sewage. The design of these two filter tanks 12 is to achieve deeper purification. The primary filter tank 121 first processes the sewage flowing out of the sedimentation tank 11 to remove a portion of the remaining suspended solids. The secondary filter tank 122 then filters the fine impurities that may still exist after the primary filter tank 121 treatment to achieve higher purification standards. The primary filter tank 121 and the secondary filter tank 122 are provided with a filter tank water distribution pipe 26 connected to the sedimentation effluent pipe 21 above them. A filter tank water distribution pipe 26 is provided above the primary filter tank 121 and the secondary filter tank 122. The function of this filter tank water distribution pipe 26 is to connect the sedimentation effluent pipe 21 of the sedimentation tank 11. After the sewage is preliminarily treated in the sedimentation tank 11, it flows through the sedimentation effluent pipe 21 to this filter tank water distribution pipe 26, which then distributes the water flow to the primary filter tank 121 and the secondary filter tank 122. This ensures the continuity of the treatment process and also allows the water inflow of the two filter tanks 12 to be adjusted as needed to optimize the efficiency and effectiveness of the entire purification process. Again, a water purification hanging material 30 is hung below the filter tank water distribution pipe 26 of the primary filter tank 121 and the secondary filter tank 122. The water purification hanging material 30 utilizes its own adsorption effect. When the sewage enters the filter tank 12, the sewage comes into contact with the water purification hanging material 30, which adsorbs the suspended impurities in the sewage, thereby effectively removing the impurities in the sewage.

[0026] To ensure that the sewage is evenly distributed on the surface of the filter material, such as Figure 2 and Figure 3As shown, a filler area water distribution pipe 25 is arranged above the microbial filler tank 13 and connected in parallel with the filter tank effluent pipe 22. The filler area water distribution pipe 25 is a "eye" structure and covers the filler area 131. The "eye" structure water distribution pipe realizes natural balanced distribution of water flow through physical structure, so that the water input from the filter tank effluent pipe 22 can be uniformly distributed on the filter material surface, and then slowly infiltrate into the filter material under the action of gravity. According to the degradation characteristics of various pollutants by hundreds of microbial groups such as bacteria, fungi, extracellular enzymes and plants in the filter material, and relying on the gravity of the infiltrating sewage for autonomous respiration, the oxygen supply for the internal microbial reaction of the filter material system is unpowered, thereby providing a stable and reliable oxygen source for the aerobic microorganisms in the microbial reaction system. In the whole microbial reaction water purification system, different microbial groups degrade and remove different pollutants under the coupling and synergistic action of different microbial layers. The microbial groups cultivated in the system are the main executors of degrading and removing pollutants. Through complex physical structure and biological reaction, efficient degradation and purification of various pollutants in sewage are achieved.

[0027] In order to improve the filter material filled in the microbial filler tank 13, as shown in Figure 2 and Figure 4 The bottom of the filler area 131 is also provided with a horizontal aeration pipe 27, and the horizontal aeration pipe 27 is also provided with a vertical aeration pipe 28 extending through the filler area 131 to the outside of the water purification tank 1. The main function of the aeration pipe is to transport air to the inside of the filler area 131 and increase the dissolved oxygen content in the water body. This is crucial for maintaining the activity of aerobic microorganisms in the microbial filler area 131. Aerobic microorganisms need sufficient oxygen in the process of degrading harmful substances in sewage, so the horizontal aeration pipe 27 and the vertical aeration pipe 28 can ensure that the microorganisms have enough oxygen for respiration, accelerating the biodegradation process of pollutants. Through aeration, not only can the oxygen supply be improved, but also the water flow can be promoted, avoiding the formation of anaerobic or anoxic environment in the filler area 131, which helps to maintain the diversity and activity of microbial communities, so that different types of microorganisms can synergistically act to more efficiently remove various pollutants.

[0028] In order to facilitate the replacement and cleaning of the equipment in the purification tank, as shown in Figure 1 and Figure 2As shown, the first access port 41 and the second access port 42 are arranged on the water purification tank 1, the first access port 41 is located above the first filter tank 121 and the second filter tank 122, which provides a direct access way for these two key purification links. When the filter material in the filter tank 12 needs to be replaced, cleaned or maintained, the staff can quickly enter through the first access port 41 to carry out the necessary inspection, cleaning or replacement work; the second access port 42 is arranged above the microbial filler tank 13, which provides convenience for the maintenance of the microbial filler area 131. The microbial filler is the key part of biological degradation in the system, and may need to check the microbial activity regularly, supplement or adjust the filler, or even manage the microbial community in the system. Through the second access port 42, the filler can be easily observed, sampled and analyzed or adjusted to maintain and optimize the microbial treatment efficiency.

[0029] The purpose of the sedimentation tank 11 is to remove large particles and suspended solids in the wastewater that have not been treated by the front-end anaerobic conditioning tank. The sedimentation tank intercepts large particles in the wastewater through the arranged grid net 29 to prevent them from entering the subsequent treatment units. The suspended solids in the wastewater are precipitated to the bottom of the grid net 29 by using the principle of gravity settling, thereby realizing preliminary solid-liquid separation.

[0030] The bottom of the transverse aeration pipe 27 is provided with a support plate 31 for supporting the filter material in the filler area 131.

[0031] The above is part of the specific implementation of the present application, and does not limit the protection scope of the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
