Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to an integrated wastewater treatment device with non-powered uniform influent. Background Technology

[0002] Rural domestic sewage treatment is an important aspect of improving the rural living environment and raising the living standards of rural residents, and it is also a significant indicator of rural modernization. With the improvement of rural living standards, flush toilets are becoming more common in rural households, leading to increased water consumption for washing. Consequently, the amount of domestic water used and the rate of centralized water supply in rural areas are increasing year by year, resulting in a corresponding increase in the discharge of rural domestic sewage. Large amounts of untreated rural domestic sewage are being discharged, becoming one of the main causes of environmental pollution such as eutrophication in rural areas, lakes, and rivers.

[0003] Rural domestic sewage treatment is crucial for improving water quality in rural areas. Compared to urban areas, rural domestic sewage treatment has the following characteristics: rural areas have relatively weak economic foundations, resulting in limited funding for water pollution control; supporting infrastructure is poor, lacking corresponding testing facilities and monitoring personnel; individual sewage treatment facilities are small in scale, but the sheer number of facilities makes operation and supervision difficult. As decentralized sewage treatment equipment, most have a treatment capacity of less than 5.0 m³. 3 / d, the water intake needs to be lifted by a booster pump, but there are very few or no small booster pumps available on the market. Therefore, using above-ground equipment not only increases investment and operating costs, but may also cause the pump to burn out due to stalling or unstable water intake during long-term operation.

[0004] For buried equipment, there is usually no need for a booster pump, and sewage flows into the equipment by gravity. However, when the influent fluctuates greatly, even if an equalization tank is set up at the front end of the treatment, it is impossible to guarantee the uniformity and stability of the influent. This will inevitably affect the treatment effect of sewage. In particular, when the influent volume is larger than the actual design volume and the water flow rate is fast, the sewage retention time and the contact reaction time with the packing material will not meet the design requirements, resulting in unsatisfactory treatment effect. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide an integrated wastewater treatment device with non-powered uniform influent flow, so as to improve the treatment effect of wastewater.

[0006] This utility model solves the above problems through the following technical means:

[0007] A non-powered, uniform-flow influent wastewater treatment integrated device includes a treatment tank, an inlet pipe, and an outlet pipe. A uniform-flow inlet trough is suspended from the top of the treatment tank. A support plate is installed at the bottom left side of the uniform-flow inlet trough. The left side wall of the uniform-flow inlet trough is connected to the support plate via an inclined return spring. The support plate is fixedly connected to the side wall of the treatment tank. A biological filter module is installed below the uniform-flow inlet trough. The biological filter module includes a shell with a top opening, a mesh plate on the top of the shell, and a partition dividing the interior of the shell into an inlet chamber and an outlet chamber. A water passage is formed between the bottom of the partition and the bottom plate of the shell. Both the inlet chamber and the outlet chamber are filled with biological filler. The inlet pipe extends to the upper left side of the uniform-flow inlet trough, and the outlet pipe communicates with the bottom of the treatment tank.

[0008] Furthermore, the height of the inlet chamber is greater than the height of the outlet chamber.

[0009] Furthermore, the two opposite sidewalls of the treatment tank are vertically alternately provided with multiple biological filter media modules, with the inlet chamber of the upper biological filter media module corresponding to the outlet chamber of the lower biological filter media module.

[0010] Furthermore, the biological filler is biological ceramic granules, glass pumice, or polyurethane sponge filler.

[0011] Furthermore, the dimension of the uniform water inlet tank supported by the support plate is smaller than the dimension of the uniform water inlet tank being suspended.

[0012] Furthermore, the treatment tank is equipped with a ventilation structure.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] The integrated wastewater treatment equipment with equalized influent flow rate disclosed in this application first allows wastewater to flow into the equalized influent tank. As the water volume increases to a certain level, the equalized influent tank tilts to the side without support plate, pouring the wastewater into the corresponding biological filter module below. After purification by the biological filter module, the wastewater is discharged. After the wastewater in the equalized influent tank has been emptied, it returns to its original position under the elastic pull of the return spring, allowing for the next round of water intake. In this way, the wastewater is buffered and transferred before reacting with the biological filter module, rather than flowing through the biological filter module continuously. Therefore, it is less affected by water flow fluctuations, ensuring sufficient reaction time between the wastewater and the biological filter module. Furthermore, the relatively consistent water volume poured into the equalized influent tank each time helps improve the uniformity of water distribution. In addition, the pouring method of water distribution also helps improve the dissolved oxygen effect. Attached Figure Description

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0016] Figure 1This is a schematic diagram of a preferred embodiment of the present invention. Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0018] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing and simplifying the description of this utility model, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0019] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified.

[0020] like Figure 1As shown, this embodiment provides a non-powered, uniform-flow influent wastewater treatment integrated device, including a treatment tank 4, an inlet pipe 1, and an outlet pipe 8. A uniform-flow influent trough 3 is suspended from the top of the treatment tank by a rope 2. A support plate 7 is provided at the bottom left side of the uniform-flow influent trough. The left side wall of the uniform-flow influent trough is connected to the support plate by an inclined return spring 6. The support plate is fixedly connected to the side wall of the treatment tank. The dimension of the uniform-flow influent trough supported by the support plate is smaller than the dimension of the uniform-flow influent trough suspended in the air. A biological filter media module is provided below the uniform-flow influent trough. The biological filter module includes a shell 505 with a top opening, a grid plate 501 set on the top of the shell, and a partition 503 that divides the interior of the shell into an inlet chamber 502 and an outlet chamber 504. The height of the inlet chamber is greater than the height of the outlet chamber. A water passage is formed between the bottom of the partition and the bottom plate of the shell. Both the inlet chamber and the outlet chamber are filled with biological filler, which is biological ceramic granules, glass pumice, or polyurethane sponge filler. The inlet pipe extends to the upper left side of the equalization inlet tank, and the outlet pipe is connected to the bottom of the treatment tank.

[0021] During operation, wastewater first flows into the equalization inlet tank. As the water volume increases to a certain level, the equalization inlet tank tilts to the side without support plates, pouring the wastewater into the corresponding biological filter module below. After purification by the biological filter module, the wastewater is discharged. After the wastewater in the equalization inlet tank has been emptied, the equalization inlet tank returns to its original position under the elastic pull of the return spring, allowing for the next round of water intake. In this way, the wastewater is buffered and transferred before reacting with the biological filter module, rather than flowing through the biological filter module continuously. Therefore, it is less affected by water flow fluctuations, ensuring sufficient reaction time between the wastewater and the biological filter module. Furthermore, the relatively consistent water volume poured into the equalization inlet tank each time helps improve the uniformity of water distribution. In addition, the pouring method of water distribution also helps improve the dissolved oxygen effect.

[0022] As a further improvement to the above technical solution, multiple biological filter media modules are arranged vertically and alternately on the two opposite sidewalls of the treatment tank, with the inlet chamber of the upper biological filter media module corresponding to the outlet chamber of the lower biological filter media module. In this way, wastewater flows back and forth through each biological filter media module from top to bottom, further improving the wastewater treatment effect.

[0023] Furthermore, the treatment tank is equipped with a ventilation structure. Specifically, if the treatment tank is above ground, the ventilation structure is a vent; if the treatment tank is underground, the ventilation structure is a duct. Oxygen is naturally introduced through the ventilation structure, eliminating the need for additional aeration power and thus saving aeration energy consumption.

[0024] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
