[0002] Sewage treatment is an important link of environmental protection and resource recycling, and is widely used in domestic sewage, industrial wastewater and rural decentralized sewage treatment scene. Sewage treatment equipment removes solid impurities, organic pollutants and other harmful substances in sewage by physical, chemical or biological methods to meet discharge standards or recycling requirements. Among many sewage treatment technologies, physical filtration is widely used due to its simple process and relatively low cost, especially in small or decentralized sewage treatment systems. Physical filtration equipment usually uses filter screen, filter plate or sedimentation tank to preliminarily treat sewage to separate solid impurities and improve water quality.

[0030] As shown in Figures 1 to 6 As shown in Figures 1 to 6 The utility model provides a kind of integrated high shaft no power sewage treatment equipment, the equipment utilizes gravity drive to realize multistage filtration, without external power, compact structure, it is applicable to domestic sewage or small industrial sewage treatment scene. The equipment mainly includes treatment pool 1, cover 2, baffle 3, filter plate 12 and delivery pipeline 13 etc. component, the following to each component and its working principle are described in detail.

[0031] The treatment pool 1 is the main component for containing and treating sewage, and the top is open structure. The cover 2 is covered on the top opening of the treatment pool 1, for closing treatment pool 1, prevent foreign matter from entering and ensure the sanitation of treatment process. The cover 2 is provided with upwardly extending shaft 21, the shaft 21 is hollow tubular structure, and the upper end is open and provided with detachable cover 22, the cover 22 is used to close the upper end opening of the shaft 21. The setting of the shaft 21 is convenient for connecting with external sewage discharge pipeline to guide sewage into the treatment pool 1. Preferably, the shaft 21 and cover 2 are made by integral molding process to enhance the structural strength and sealing property.

[0032] Three baffle plates 3 are arranged inside the treatment pool 1, and the baffle plates 3 are arranged vertically along the length or width direction of the treatment pool 1, so as to divide the internal space of the treatment pool 1 into four treatment cavities 11 arranged in sequence, which are respectively the first treatment cavity, the second treatment cavity, the third treatment cavity and the fourth treatment cavity (for example, named from right to left in sequence). Each treatment cavity 11 is communicated through a specific structure for filtering sewage step by step.

[0033] Three adjacent treatment cavities 11 are respectively provided with filter plates 12, and the filter plates 12 are fixed horizontally at the middle or lower part of the treatment cavities 11, for intercepting solid impurities in sewage. The filter plate 12 adopts a porous filter structure and is made of plastic, and the pore size is set according to the filtering requirement to balance the filtering effect and water flow efficiency. Each filter plate 12 is provided with a delivery pipeline 13, and the delivery pipeline 13 is a hollow tubular member, and the upper end opening is located on the upper surface of the filter plate 12 or slightly higher than the filter plate 12, and the lower end penetrates through the filter plate 12 and extends to the space below the filter plate 12, and is communicated with the adjacent next treatment cavity 11. Preferably, the lower end outlet of the delivery pipeline 13 is located above the filter plate 12 of the next treatment cavity 11, so as to ensure that the filtered water can smoothly enter the next treatment cavity for further filtering.

[0034] The wastewater treatment process is as follows: Wastewater enters the rightmost anaerobic treatment chamber 11 through the well shaft 21. This chamber is filled with anaerobic bacterial carrier floats, and volcanic rock is laid at the bottom as a biofilm attachment substrate. Anaerobic bacteria form a biofilm on the surface of the floats and volcanic rock, achieving stratified anaerobic degradation of the wastewater. The remaining treatment chambers 11 are filled with zeolite and ceramic filter media. In the treatment chambers 11, wastewater flows through filter plates 12, where solid impurities are intercepted and accumulate on the upper surface of the filter plates 12. The filtered water enters the space below the filter plates 12 through the pores. As wastewater continues to be input, the water level below the filter plates 12 gradually rises. When the water level reaches the upper opening of the conveying pipe 13, the filtered water flows into the adjacent treatment chamber 11 through the conveying pipe 13. Subsequently, the wastewater undergoes a similar process, with the filter plates 12 performing a second filtration, and the filtered water enters the next treatment chamber 11 through the conveying pipe 13. The filter plates 12 in the treatment chamber 11 perform a third filtration, and the filtered water enters the next treatment chamber (e.g., the leftmost treatment chamber) through the conveying pipe 13. The treatment chamber 11 on the left serves as the final clean water collection chamber, used to store the treated water that has undergone multi-stage filtration. The side wall of the fourth treatment chamber is provided with an outlet (not shown in the figure) to discharge the treated water or direct it to other uses.

[0035] This invention achieves a multi-stage filtration process without power drive through the rational design of the well shaft 21, baffle 3, filter plate 12, and conveying pipeline 13. Wastewater passes through each treatment chamber 11 sequentially by gravity, gradually removing solid impurities, resulting in high treatment efficiency and low operating costs. Furthermore, the well shaft 21 facilitates connection with sewage pipes, and the overall structure is simple, easy to install and maintain, making it suitable for various wastewater treatment scenarios.

[0036] In this embodiment, the partition 3 has a slot 31 on its side, and the inner wall of the treatment tank 1 has a corresponding protrusion 14 that matches the slot 31. The protrusion 14 is embedded in the slot 31, thereby fixing the partition 3 to the inner wall of the treatment tank 1 and achieving a stable connection between the partition 3 and the treatment tank 1. Preferably, the slot 31 and the protrusion 14 are tightly fitted, for example by interference fit or by adding a sealing strip, to ensure the sealing between adjacent treatment chambers 11 and prevent untreated sewage from directly leaking into the next treatment chamber. This connection method not only facilitates the installation and disassembly of the partition 3, but also improves the overall structural stability of the equipment.

[0037] In the embodiment, the cover 2 is detachably connected to the top edge of the treatment tank 1 by bolts. The bolts are uniformly distributed around the periphery of the cover 2 and correspondingly match the pre-set bolt holes on the top of the treatment tank 1 to form a firm fixing structure. The bolt connection facilitates quick installation and disassembly of the cover 2, providing convenience for maintenance, cleaning or replacement of internal components of the equipment. Preferably, a sealing gasket is arranged on the contact surface between the cover 2 and the treatment tank 1 to enhance the sealing performance of the connection part and prevent leakage of sewage or odor.

[0038] In the embodiment, the lower surface of the filter plate 12 is provided with a plurality of support feet 15, the lower ends of which are fixedly connected to the bottom wall of the treatment tank 1 for supporting the filter plate 12 and preventing it from deforming or sinking under the long-term impact of sewage or the heavy pressure of accumulated impurities. The support feet 15 are preferably made of the same or compatible material as the treatment tank 1, such as stainless steel or high-strength plastic, to ensure corrosion resistance and stability during long-term use. The number and distribution of the support feet 15 are determined according to the area and stress condition of the filter plate 12, and are preferably 3 to 6 evenly distributed to provide balanced support force. The connection between the support feet 15 and the bottom wall of the treatment tank 1 can be achieved by welding, bolt fixing or one-piece forming, etc., and the specific method is selected according to the manufacturing process. Preferably, the height of the support feet 15 is set to form a proper space between the filter plate 12 and the bottom wall of the treatment tank 1, facilitating the collection of filtered water and ensuring smooth water flow.

[0039] Further, the upper surface of the filter plate 12 can be provided with a guide structure (not shown in the figure), such as an inclined flow guide groove or a raised flow guide strip, for guiding the uniform distribution of sewage on the filter area of the filter plate 12, avoiding excessive accumulation of local impurities and improving the filtering efficiency. A sealing ring or a fixed flange is arranged at the connection between the delivery pipeline 13 and the filter plate 12 to prevent leakage at the pipeline interface and ensure that the filtered water only enters the next treatment chamber through the delivery pipeline 13.

[0040] In the embodiment, the working process of the sewage treatment equipment does not require external power and relies entirely on gravity to achieve step-by-step filtration of sewage, having the advantages of low operating cost and simple maintenance. Specifically, after the sewage enters the treatment chamber 11 through the well shaft 21, it is filtered in turn by each filter plate 12, and solid impurities are intercepted step by step. The filtered water gradually enters the subsequent treatment chamber through the delivery pipeline 13 and is finally collected as treated clean water in the fourth treatment chamber. The whole process is compact in structure and stable in operation, and is suitable for sewage treatment needs in rural areas, remote areas or small communities.

[0041] As Figure 7 shown, in the embodiment, the bottom surface of the treatment tank 1 is provided with a reinforcing rib 16 for improving the wear resistance of the bottom surface of the treatment tank 1.

[0042] In the embodiment, the lower surface of the cover 2 is provided with a strip-shaped protrusion 23, and the reinforcing beam 33 of the partition plate 3 is provided with a strip-shaped slot 32 matched with the strip-shaped protrusion 23. The strip-shaped protrusion 23 of the cover 2 is connected with the strip-shaped slot 32 in a plug-in manner.
