Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1The non-powered sewage purification tank device in this embodiment includes a first reaction chamber 11, a second reaction chamber 12, an air inlet pipe 13, an exhaust pipe 14, and a chamber connecting pipe 15. The first reaction chamber 11 and the second reaction chamber 12 form a reactor. Both the first reaction chamber 11 and the second reaction chamber 12 are located below the ground surface, and the tops of both the first reaction chamber 11 and the second reaction chamber 12 extend to the outside of the ground surface. An inlet flange is provided at a high point outside the first reaction chamber 11, and an outlet pipe is provided at the bottom outside the second reaction chamber 12.

[0027] A partition is fixed inside the reaction chamber 11, which divides the reaction chamber 11 into two spaces, front and back. A plastic flexible plate 112 is fixed at the bottom of the partition. The plastic flexible plate 112 and the partition work together at the bottom of the reaction chamber 11 to form a one-way sealing structure, which can also block the passage of large particles. The chamber connecting pipe 15 is set at the top of the reaction chamber 11 and the reaction chamber 2 12 and is connected to both. The front and back spaces are filled with fiber filler 111 and flow stabilizer vertical pipe filler 113, respectively.

[0028] Fiber packing 111 is a biofilm carrier or filter medium composed of fiber materials (aldehyde fiber, polyester filament, basalt fiber, etc.). It promotes microbial attachment or physical interception of pollutants through high specific surface area and pore structure. It is widely used in sewage treatment, water filtration and other scenarios, and has the characteristics of high mass transfer efficiency, shock load resistance and corrosion resistance. The design and application of steady flow vertical pipe packing 113 involves fluid distribution optimization, pressure drop control and structural stability. It is commonly used in chemical, water treatment and other fields.

[0029] The fiber packing 111 is located in the middle of the front part of the reaction chamber 11, with a gap at its bottom. The fiber packing 111 fills the filling area. The flow stabilizing vertical pipe packing 113 is located in the middle of the rear part of the reaction chamber 11, with a gap at its bottom. The pore size of the flow stabilizing vertical pipe packing 113 is 30-65mm.

[0030] Please refer to it again. Figure 1 and Figures 2 to 4 In this embodiment, the reaction chamber 2 12 is composed of a water supply component, a drip water distributor 122, and a multi-stage biological packing structure.

[0031] The water supply assembly includes a pulse water distributor 1211, a water storage tank 1212, and a water distributor 1213. The water storage tank 1212 is located above the reaction chamber 12 and is equipped with the pulse water distributor 1211. When the liquid level reaches the design height, all the wastewater in the tank can be siphoned into the water distributor 1213. The outlet of the pulse water distributor 1211 is connected to the inlet of the water distributor 1213. The water distributor 1213 is located below the water storage tank 1212 and has four or more outlets. The horizontal water flows into the drip water distributor 122.

[0032] It should be noted that the ends of the chamber connecting pipe 15 are fixedly connected to the rear of the reaction chamber 11 and the upper part of the water storage tank 1212, respectively.

[0033] The drip distributor 122 is a top-open chamber that can hold all the wastewater in the storage tank 1212. The bottom of the drip distributor 122 is provided with a triangular water collection structure, and the triangular water collection structures form an inverted triangular space. The bottom of the drip distributor 122 has evenly distributed water outlets that are connected to the inverted triangular space, which allows the wastewater to drip slowly into the multi-stage biological packing structure below.

[0034] In addition, the multi-level biological packing structure consists of anoxic packing 1231 and aerobic packing 1232 arranged vertically. The anoxic packing 1231 and aerobic packing 1232 are arranged vertically in the lower part of the reaction chamber 12. The anoxic packing 1231 is attached with special anoxic microbial strains, and the aerobic packing 1232 is attached with special aerobic microbial strains. The voids of the aerobic packing 1232 are larger than those of the anoxic packing 1231.

[0035] Anoxic packing material 1231 is a biofilm carrier for facultative anaerobic environments (between aerobic and anaerobic). It degrades pollutants through the attachment and metabolism of microorganisms and is suitable for various scenarios such as wastewater treatment and surface water remediation. Its core feature is its adaptability to low dissolved oxygen conditions and its ability to promote the synergistic effect of different bacterial communities, achieving efficient nitrogen and phosphorus removal and organic matter decomposition. Aerobic packing material 1232 is a microbial carrier specifically designed for aerobic biological treatment. It promotes microbial attachment and metabolism by providing a high specific surface area and pore structure, achieving efficient organic matter degradation and nitrogen removal. It is mainly used in aeration tanks, contact oxidation tanks, and other scenarios in wastewater treatment and features strong heat dissipation, high oxygen utilization rate, and resistance to shock loads.

[0036] It should be noted that both anoxic filler 1231 and aerobic filler 1232 have a large specific surface area, and their material surfaces are both highly hydrophilic.

[0037] In this embodiment, wastewater enters through the inlet flange, is filtered by fiber packing 111 and flow stabilizer vertical pipe packing 113, and then is transported to the storage tank 1212 through the chamber connecting pipe 15. Using pulse water distribution technology, the wastewater in the storage tank 1212 is siphoned into the distributor 1213 through the pulse water distributor 1211, and the wastewater is horizontally discharged into the drip water distributor 122. Finally, it passes through the anoxic packing 1231 and the aerobic packing 1232 in sequence, and is discharged from the discharge pipe, thus achieving overall wastewater purification.

[0038] Furthermore, the air inlet duct 13 is located at the bottom of the aerobic packing 1232, the air inlet duct 13 passes through the reaction chamber 2 12 and is located above the discharge port, and the air inlet of the air inlet duct 13 is higher than the top of the reactor and located above the ground.

[0039] The exhaust duct 14 consists of a pipe and a wind-driven negative pressure fan 141. The pipe is located above the reactor. The top air inlet of the exhaust duct 14 is equipped with a wind-driven negative pressure fan 141, which can be driven by natural wind to generate negative pressure, extracting gas from the interior of the second reaction chamber 12 for ventilation. The bottom of the exhaust duct 14 is connected to the top surface of the second reaction chamber 12.

[0040] In this embodiment, the air inlet duct 13 injects air into the reactor, and the external natural wind drives the negative pressure fan 141 to rotate. The gas inside the reactor is discharged from the exhaust duct 14, thus achieving oxygen supply to the reactor as a whole and completely eliminating dependence on external energy.

[0041] It is known that the technical entry point of this invention is:

[0042] 1. No power drive: The water flow is pressurized using pulse water distribution technology, and the negative pressure ventilation system is driven by natural wind to supply oxygen, completely eliminating dependence on external energy.

[0043] 2. Enhance mass transfer and biochemical reaction: Improve pollutant degradation efficiency through the synergistic effect of fiber packing 111, steady flow vertical pipe packing 113 and multi-stage biological packing facultative and aerobic.

[0044] 3. Modular design: The structure is compact, suitable for different scales of sewage treatment needs, and easy to maintain, adaptable to decentralized application scenarios.

[0045]

[0046]

[0047] As can be seen from the above comparison, the present invention breaks through the existing technical bottlenecks in terms of non-powered operation, processing efficiency, and adaptability, and has significant technical progress and application value.

[0048] The working principle of the above embodiments is as follows:

[0049] Wastewater enters through the inlet flange, is filtered by fiber packing 111 and flow-stabilizing vertical pipe packing 113, and then transported to the storage tank 1212 through the chamber connecting pipe 15. Utilizing pulse water distribution technology, when the liquid level reaches the designed height, the wastewater in the storage tank 1212 is siphoned into the distributor 1213 through the pulse water distributor 1211, and the wastewater is horizontally discharged into the drip distributor 122. Finally, it passes through the anoxic packing 1231 and aerobic packing 1232 in sequence and is discharged from the outlet pipe, thus achieving overall wastewater purification. In conjunction with the negative pressure ventilation system, air is injected into the reactor through the air inlet duct 13, and the external natural wind drives the negative pressure fan 141 to rotate. The gas inside the reactor is discharged from the exhaust duct 14, thus achieving overall oxygen supply to the reactor and completely eliminating dependence on external energy.
