Description

Technical Field

[0001] This utility model relates to a resource recovery device, and more specifically, to a rural domestic sewage resource recovery device that facilitates the removal of impurities. Background Technology

[0002] Because rural pollution sources are scattered and widespread, the amount of sewage is small, and due to natural limitations, rural domestic sewage is characterized by being dispersed and difficult to collect. It is difficult to lay sewage collection pipe networks over a large area, which makes it impossible to include rural domestic sewage in large centralized sewage treatment plants for centralized treatment. The harmless treatment rate of rural domestic sewage is very low, so we can only seek suitable sewage treatment methods and processes with high efficiency and low energy consumption according to local conditions.

[0003] Currently, the commonly used processes for rural domestic sewage treatment mainly include biological treatment systems (anaerobic, anoxic, and aerobic) and ecological treatment systems, primarily non-powered anaerobic biological treatment, land treatment, and constructed wetland processes. In these systems, large-volume impurities are typically initially filtered through screens, followed by manual cleaning. However, the impurities are often dispersed on the screens, resulting in low cleaning efficiency and a heavy workload for workers. Utility Model Content

[0020] See Figure 1-3 As shown, this utility model discloses a rural domestic sewage resource utilization device that facilitates the removal of impurities. It includes an equalization tank 1, characterized in that an inlet pipe 2 is provided on one side wall of the equalization tank 1, several spherical packing materials 3 are provided at the bottom of the equalization tank 1, and a first inspection well 4 is provided at the upper end of the equalization tank 1. The first inspection well allows for the maintenance and cleaning of the equalization tank, or the extraction of water for testing and use. A well cover is provided on the first inspection well to ensure safety during normal operation.

[0021] A pre-filtration chamber 5 is provided in the regulating tank 1 at the inlet pipe 2. A water distribution pipe 6 is provided at the bottom of the pre-filtration chamber 5, and the outlet end of the water distribution pipe 6 is located at the bottom of the spherical packing 3. A filter assembly 7 is provided in the pre-filtration chamber 5 below the outlet end of the inlet pipe 2, and a mesh bag 8 is detachably installed on the filter assembly 7. After the sewage enters the pre-filtration chamber 5, it first passes through the mesh bag 8 and then through the filter assembly 7. The mesh bag is installed on the filter assembly. After the sewage is filtered by the filter assembly, large-volume impurities will remain on the mesh bag. When cleaning, the mesh bag can be lifted directly from the first inspection well to pack and remove the impurities. This is convenient and quick, effectively improving the efficiency of cleaning impurities and reducing the workload of workers.

[0022] In this embodiment, preferably, the filter assembly 7 includes a V-shaped grid 7a disposed within the pre-filtration chamber 5; a filter frame 7b detachably mounted on the grid 7a with its bottom adapted to the grid 7a, and lifting hooks 7c provided on the outer walls on both sides of the open end of the filter frame 7b; the mesh bag 8 is fitted inside the filter frame 7b. With this structure, when the mesh bag contains a large amount of impurities, the filter frame can be removed and the mesh bag taken off for packaging using a lifting device. During this process, the filter frame supports the mesh bag, which avoids the mesh bag from breaking due to the weight of the impurities compared to lifting the mesh bag separately.

[0023] The V-shaped grid and filter frame provide stable support for the mesh bag while ensuring filtration efficiency. Furthermore, the bottom of both the grid and filter frame has through holes to prevent the formation of V-shaped grooves that could lead to water accumulation.

[0024] Furthermore, the filter frame 7b has a support ring 7d made of elastic material at its open end; in use, the open end of the mesh bag 8 is turned outward and positioned between the support ring 7d and the inner wall of the filter frame 7b. This structure facilitates the opening of the mesh bag and fixes it inside the filter frame, preventing it from easily falling off.

[0025] After filtering out large impurities, the wastewater flows into the bottom of the equalization tank through the distribution pipe. While making the wastewater homogeneous in both quality and quantity, the micro-anaerobic environment in the equalization tank and the biofilm formed by the spherical packing material intercept and preliminarily decompose organic pollutants, degrading large organic molecules into small organic molecules that are easily decomposed and bioavailable.

[0026] The pretreated domestic sewage in the equalization tank can be used for irrigation of small gardens by surrounding farmers. Farmers can pump out the sewage to water their plants as needed, thus achieving resource utilization. At the same time, the equalization tank degrades large organic molecules into small organic molecules that are easily decomposed and bioavailable, reducing the organic load on subsequent treatment processes.

[0027] In this embodiment, a biological treatment tank 9 is provided on one side of the regulating tank 1. An overflow mesh 10 is provided on the side wall between the biological treatment tank 9 and the regulating tank 1. A second inspection well 11 is provided at the upper end of the biological treatment tank 9. Several biological packing materials 12 are provided in the biological treatment tank 9 through a support frame. An air exchange component 13 for air circulation with the outside is provided above the water surface in the biological treatment tank 9. After the wastewater passes through the regulating tank to degrade large organic molecules into small organic molecules, it enters the biological treatment tank. The biological packing materials adsorb the small organic molecules and decompose and convert them into substances such as water and carbon dioxide.

[0028] By installing an air exchange component at the top of the biochemical tank to enhance the introduction and flow of natural air, an aerobic environment is created in the biochemical tank, providing sufficient oxygen for aerobic microorganisms to biodegrade the organic matter adsorbed on the combined packing biofilm, thereby improving decomposition efficiency.

[0029] In this embodiment, preferably, the ventilation assembly 13 includes an air inlet pipe 13a located at the upper end of one side of the biochemical tank 9, and an air outlet pipe 13b located at the opposite end. The lower end of the air outlet pipe 13b is positioned higher than the lower end of the air inlet pipe 13a, and a non-powered fan 13c is provided at the upper end of the air outlet pipe 13b. By providing a non-powered fan at the air outlet pipe opening, the introduction and flow of natural wind can be effectively enhanced, and it is also low-carbon and energy-saving.

[0030] Furthermore, an aeration pipe 14 is installed in the biological treatment tank 9. By installing the aeration pipe, air is guided into the sewage below the biological packing material, allowing the air to fully contact the biological packing material, thereby providing sufficient oxygen for the aerobic microorganisms and improving the biodegradation efficiency.

[0031] In this embodiment, an effluent pool 15 is provided on one side of the biological treatment tank 9, and a water passage hole 16 is provided at the bottom of the side wall between the biological treatment tank 9 and the effluent pool 15; a flow equalization plate 17 is provided in the effluent pool 15 above the water passage hole 16, and a filter packing layer 18 is provided on the flow equalization plate 17; an overflow outlet pipe 19 is provided on the side wall of the effluent pool 15 above the filter packing layer 18, and a third maintenance well 20 is provided at the upper end of the effluent pool 15. After being purified by the biological treatment tank, the wastewater enters the effluent pool from the bottom and is homogenized and equalized by the flow equalization plate; the filter packing layer is composed of filter media such as gravel, which can intercept the remaining suspended particulate matter, organic matter and other pollutants in the wastewater, further purifying the water quality and making the effluent meet the standards.

[0032] In this embodiment, a water pump 21 is installed on the regulating tank 1 on one side of the first inspection well 4. The water pump facilitates the removal of treated wastewater from the regulating tank for testing and use, eliminating the need to draw water through the first inspection well.

[0033] During operation, domestic sewage enters the equalization tank through the inlet pipe and is filtered through a mesh bag to remove large impurities. The sewage then flows through the distribution pipe to the bottom of the equalization tank, where it undergoes preliminary decomposition of organic pollutants by spherical packing material. It then overflows into the biological treatment tank, where biological packing material adsorbs small-molecule organic matter and decomposes it into substances such as water and carbon dioxide.

[0034] After purification in the biological treatment tank, the wastewater enters the effluent tank through the water passage at the bottom. After being homogenized and evenly distributed by the flow equalization plate, the remaining suspended particulate matter, organic matter and other pollutants in the wastewater are intercepted by the filter packing layer. Finally, it overflows and is discharged through the overflow outlet pipe.

[0035] The above-described embodiments are preferred embodiments of the present utility model and are only used to facilitate the illustration of the present utility model. They are not intended to limit the present utility model in any way. Any person skilled in the art who makes partial modifications or alterations to the technical content disclosed in the present utility model without departing from the scope of the technical features of the present utility model shall still fall within the scope of the technical features of the present utility model.
