Description

Technical Field

[0001] The utility model relates to the field of sewage purification devices, in particular to an agricultural sewage water purification device. Background Art

[0002] Agricultural water pollution mainly refers to water pollution caused by improper use of fertilizers and pesticides, waste discharge from poultry farming, and arbitrary disposal of agricultural waste during agricultural production activities. This type of pollution is extensive, hidden, and cumulative, and is not easy to be discovered. It has long-term impacts and harms on agricultural production and the ecological environment. Therefore, it is crucial to strengthen the purification of agricultural water.

[0003] To address the above issues, the invention patent document with publication number CN106396289A discloses an agricultural sewage purification device, which connects a sedimentation and filtration box, an anaerobic treatment box, an aerobic treatment box and a secondary sedimentation treatment box through a pipe. Under the action of a pressure pump, the sewage flows through the pipe in sequence through the sedimentation and filtration box, the anaerobic treatment box, the aerobic treatment box and the secondary sedimentation treatment box to complete purification.

[0004] Under the action of the pressure pump, the water in the above-mentioned water purification device passes through the sedimentation and filtration box, anaerobic treatment box, aerobic treatment box and secondary sedimentation treatment box in sequence. Although it reduces the treatment time of wastewater, it still has certain shortcomings when used: for different volumes of water, the pressure required to enter the next treatment box through the pipeline is different, and the working parameters of the pressure pump need to be adjusted in time, resulting in an increase in the process. In addition, during the long-term use of the pressure pump, it will generate a lot of noise, affecting the use environment. At the same time, it requires regular maintenance and replacement of seals and other wearing parts, which increases maintenance costs. Utility Model Content

[0005] The utility model provides an agricultural sewage water cleaning treatment device to solve the technical problems of complicated water cleaning procedures and high equipment operation costs in the prior art.

[0006] In order to solve the above problems, the agricultural sewage cleaning water treatment device provided by the present invention adopts the following technical solutions:

[0007] A device for treating agricultural sewage water includes a water cleaning pool. The water cleaning pool is provided with a water inlet for connecting to an agricultural water outlet on the side close to the agricultural water reservoir, and a water outlet on the side away from the agricultural water reservoir. The water cleaning pool has a water cleaning structure, characterized in that the water cleaning structure includes, in the direction from the water inlet to the water outlet, the following in sequence:

[0008] Plastic netting, which is used to initially filter out large particles of weeds and debris;

[0009] A stainless steel mesh, which is used to further remove smaller particles and impurities, and the mesh size of the stainless steel mesh is smaller than the mesh size of the plastic mesh;

[0010] A first iron box body having sand inside for filtering fine particles and suspended matter;

[0011] The second iron box has activated carbon inside for removing pigments, odors and pollutants in the water.

[0012] Furthermore, the size of the water inlet is larger than the size of the water outlet.

[0013] Furthermore, the water outlet is arranged eccentrically relative to the central axis of the water inlet.

[0014] Furthermore, the plastic net is fixed to the inner wall of the clean water pool through metal clips.

[0015] Furthermore, a stainless steel mesh is attached to the first iron bar box.

[0016] Furthermore, the first iron bar box and the second iron bar box are both box structures made of stainless steel mesh.

[0017] Furthermore, a pre-buried rack is provided at the bottom of the clean water pool, and the pre-buried rack is used to fixedly connect the first iron bar box body and the second iron bar box body.

[0018] Furthermore, the length of the first iron bar box and the second iron bar box are both 1.5 meters, the thickness are both 0.1 to 0.3 meters, and the height are both 1.5 meters.

[0019] Furthermore, the clean water pool has a wall made of cement concrete, and the thickness of the cement concrete wall structure is 0.1 to 0.3 meters.

[0020] Furthermore, the height of the clean water pool wall is 0.8 to 1.5 meters higher than the height of the agricultural water storage tank wall.

[0021] The beneficial effects of the agricultural sewage cleaning water treatment device provided by the utility model are:

[0022] 1) Compared with the prior art, the present application uses cement concrete as the wall material of the water cleaning pool, and sets a plastic net, a stainless steel net, a first iron box containing sand, and a second iron box containing activated carbon in the water cleaning pool as a water cleaning structure for removing impurities. On the basis of ensuring that agricultural sewage reaches Class 2 water quality after water cleaning treatment, the overall structure of the structure is simple and inexpensive. It does not require electricity to provide pressure to ensure that the sewage enters the next water cleaning device. It can be more suitable for remote places in the wild, and the entire device runs without noise and pollution. The subsequent process of replacing the water cleaning structure is simple, which can greatly reduce the operating cost.

[0023] 2) The design of the water inlet diameter being larger than the water outlet diameter ensures that sewage can enter the treatment device smoothly, improves treatment efficiency, and is energy-saving and environmentally friendly; at the same time, the water outlet is arranged eccentrically relative to the central axis of the water inlet, which optimizes water flow distribution and reduces impact and vibration, so that the treated agricultural water can be discharged smoothly, ensuring the stability of the water purification device.

[0024] Through the above configuration, the present invention completes the improvement and upgrade of the existing water purification device, and effectively solves the technical problems of complicated water purification process and high equipment operation cost in the prior art.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0030] It should be noted that the main concept of the agricultural sewage water cleaning treatment device provided by the present invention is: using a plastic net, a stainless steel net, a first iron bar box containing sand, and a second iron bar box containing activated carbon as a water cleaning structure, and cleaning the agricultural sewage in four steps, which can ensure the water cleaning effect. At the same time, the entire water cleaning treatment device is inexpensive, and the water cleaning structure is easy to replace during subsequent use. The operating cost is low and does not require special supervision. The design of the water outlet being smaller than the water inlet speeds up the speed at which agricultural sewage enters the water cleaning structure. The water outlet is eccentrically arranged relative to the central axis of the water inlet to optimize the water flow distribution so that the treated agricultural water can be discharged smoothly, ensuring the stability of the water cleaning device.

[0031] After introducing the basic principles of the present invention, various non-limiting embodiments of the present invention are described in detail below. The numbers of any elements in the drawings are for illustration only and not for limitation, and any names are for distinction only and do not have any limiting meaning.

[0032] The principle and spirit of the present invention are explained in detail below with reference to several representative embodiments of the present invention.

[0033] Example 1 of an agricultural sewage cleaning water treatment device provided by the utility model:

[0034] like Figure 1 As shown, the agricultural sewage water cleaning treatment device includes a clean water pool 1. The clean water pool 1 is provided with a water inlet 2 for connecting to the agricultural water outlet on the side close to the agricultural water reservoir 10, and a water outlet 3 on the side away from the agricultural water reservoir 10.

[0035] Among them, the size of the water inlet 2 is larger than that of the water outlet 3, which can ensure that the sewage enters the water purification device smoothly and improve the treatment efficiency. The water outlet 3 is eccentrically arranged relative to the central axis of the water inlet 2. This arrangement optimizes the water flow distribution and reduces the impact and vibration of the water flow, so that the treated agricultural water can be discharged smoothly, ensuring the stability of the operation of the water purification device.

[0036] The following is a detailed introduction to the water purification structure inside the water purification pool 1. In the direction from the water inlet 2 to the water outlet 3, the water purification structure includes: a plastic mesh 4 for initially filtering large particles of weeds and debris; a stainless steel mesh 5 for further removing smaller particles and impurities, and the mesh size of the stainless steel mesh 5 is smaller than that of the plastic mesh 4; the interior of the first iron bar box 6 contains sand for filtering fine particles and suspended matter; the interior of the second iron bar box 7 contains activated carbon for removing pigments, odors and pollutants in the water; agricultural sewage can be successfully purified into clean water of Class 1 or Class 2 water quality after passing through the above-mentioned water purification structure.

[0037] Specifically, the plastic net 4 is fixed to the inner wall of the clean water pool 1 by the metal clip 8 to ensure that the plastic net 4 can function stably; the stainless steel net 5 in the clean water structure is attached to the first iron box 6.

[0038] In addition, the bottom of the clean water pool 1 has a pre-buried rack 9, which is used to fixedly connect the first iron box 6 and the second iron box 7; the first iron box 6 and the second iron box 7 are both box structures made of stainless steel mesh.

[0039] Specifically, the first iron bar box 6 and the second iron bar box 7 are both 1.5 meters long, 0.1-0.3 meters thick, and 1.5 meters high.

[0040] The structure of the clean water pool 1 is mainly that the clean water pool 1 is a wall made of cement concrete, the thickness of the cement concrete wall structure is 0.1 to 0.3 meters, the length of the clean water pool 1 wall is determined according to the sewage discharge volume, and the height of the clean water pool 1 wall is 0.8 to 1.5 meters higher than the height of the agricultural water storage tank 10 wall.

[0041] It should be noted that:

[0042] 1) The agricultural sewage water treatment device provided by the utility model is suitable for paddy fields with zero pesticide application and is specifically used to reduce pollution caused by fertilization (animal and plant farmyard manure) in paddy fields;

[0043] 2) The box of this device is composed of multiple parts, and multiple boxes can be installed according to the amount of sewage discharged;

[0044] 3) This device is only used to predict sewage outflow when applying farmyard manure;

[0045] 4) The sand and activated carbon in the iron box need to be replaced after a period of use;

[0046] 5) The agricultural sewage clean water treatment device provided by the utility model relies on the pressure generated by the height difference of about 2 meters between the paddy field and the horizontal plane to cause the sewage to flow out of the clean water filtering device on its own.

[0047] The working principle of the agricultural sewage cleaning water treatment device provided by the utility model is as follows: agricultural sewage enters the cleaning water pool 1 through the water inlet 2, first passes through the plastic net 4 to preliminarily filter out large particles of weeds and debris, then flows through the stainless steel net 5 to further remove smaller particles and impurities, then flows through the first iron bar box 6 containing sand to filter out even finer particles and suspended matter. At this time, the agricultural sewage is already relatively clear, and finally flows through the second iron bar box 7 containing activated carbon to remove pigments, odors and pollutants in the water. After passing through the four-stage water cleaning structure, it is ensured that the agricultural sewage can reach Class 2 water quality, completing the agricultural water cleaning process, and is discharged from the water outlet 3. The water cleaning structure is simple and easy to replace, does not require additional energy supply, has low operating costs, and is widely applicable to remote places in the wild.

[0048] Example 2 of an agricultural sewage cleaning water treatment device provided by the utility model:

[0049] The main difference between it and Example 1 is:

[0050] In embodiment 1, a second iron bar box is provided.

[0051] In this embodiment, two layers of the second iron bar box are provided.

[0052] Example 3 of an agricultural sewage cleaning water treatment device provided by the utility model:

[0053] The main difference between it and Example 1 is:

[0054] In Example 1, the size of the water inlet is larger than that of the water outlet, and the water outlet is eccentrically arranged relative to the central axis of the water inlet.

[0055] In this embodiment, the size of the water outlet is further reduced, and the number of the water outlet is set to two.

[0056] According to the above description of this specification, those skilled in the art may also understand that the terms used below, such as "front", "back", "bottom", "inside", "outside" and other terms indicating orientation or positional relationships are based on the orientation or positional relationships shown in the drawings of this specification. They are only for the purpose of facilitating the explanation of the scheme of the utility model and simplifying the description, rather than explicitly or implicitly indicating that the device or element involved must have the specific orientation, be constructed and operated in a specific orientation. Therefore, the above-mentioned orientation or positional relationship terms cannot be understood or interpreted as limitations on the scheme of the utility model.
