Description

Technical Field

[0001] The invention relates to the technical field of livestock and poultry breeding wastewater oxidation pond treatment, and specifically proposes livestock and poultry breeding wastewater ecological oxidation pond treatment equipment and process. Background Art

[0002] The ecological oxidation pond treatment process for livestock and poultry wastewater is a wastewater treatment method that uses microorganisms, plants and animals in natural ecosystems to purify water. This method is not only low-cost and easy to maintain, but also can effectively remove organic matter, nitrogen, phosphorus and other pollutants in wastewater.

[0003] The ecological oxidation pond treatment process for livestock and poultry wastewater is mainly carried out by the combination of screen sedimentation tanks and multi-stage oxidation ponds. The screen sedimentation tank is used to remove larger suspended solids and floating objects, and then the heavier inorganic particles are removed through the sedimentation tank. The multi-stage oxidation pond has the following functions: 1. Aerobic and anaerobic microorganisms in the oxidation pond decompose the organic matter in the sewage through metabolism and convert it into carbon dioxide, water and inorganic salts. The aerobic and anaerobic microorganisms come from the microorganisms in the livestock and poultry sewage, the soil microorganisms when the oxidation pond is built, the rhizosphere microorganisms of aquatic purification plants, the intestinal excretion microorganisms of aquatic animals and artificial additions; 2. Aquatic purification plants absorb nutrients in the water, such as nitrogen and phosphorus, through their roots, thereby reducing the concentration of these pollutants; 3. Aquatic animals (such as fish, etc.) help maintain ecological balance by eating algae and other microorganisms; 4. Sunlight promotes the photosynthesis of algae in oxidation ponds, produces oxygen, and promotes the activity of aerobic microorganisms.

[0004] However, the current oxidation ponds have the following defects: 1. The aeration of the oxidation pond is separated from the oxidation pond for breeding aquatic purification plants, and multiple oxidation ponds are required to cooperate, which occupies a large area. In addition, the oxidation pond is very large, and the aeration components that promote the purification effect are fixed, which easily causes uneven aeration and poor purification effect; 2. The oxidation pond currently does not have a stirring function, which causes uneven mixing of pollutants and microorganisms and poor purification effect. Summary of the invention

DETAILED DESCRIPTION

[0030] 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. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0032] See also Figure 1 , an ecological oxidation pond treatment equipment for livestock and poultry wastewater, comprising: a grille sedimentation tank 1 and an oxidation pond 2, a drainage pipe 3 is obliquely installed at the overflow outlet of the outer wall of the grille sedimentation tank 1, and the lower end of the drainage pipe 3 is connected to the inner wall of one end of the oxidation pond 2 in the length direction; the internal structure of the grille sedimentation tank 1 is not shown in the figure.

[0033] See also Figure 1 The oxidation pond 2 is provided with an integrated stirring and aeration mechanism 4; the tops of both sides of the oxidation pond 2 arranged along its width direction are slidably connected with a planting rack movable mechanism 5, the integrated stirring and aeration mechanism 4 is located below the planting rack movable mechanism 5, and the planting rack movable mechanism 5 is located on the side of the oxidation pond 2 away from the drainage pipe 3 in the length direction.

[0034] See also Figure 1 The planting rack moving mechanism 5 includes a plurality of plant planting racks 50, which are evenly arranged and slidably connected to the top of the two side walls arranged in the width direction of the oxidation pond 2 through a sliding linkage group 51, and the plant planting racks 50 are located between the two side inner walls arranged in the width direction of the oxidation pond 2.

[0035] The oxidation pond 2, the planting rack moving mechanism 5 and the stirring aeration integrated mechanism 4 cooperate with each other, thereby realizing the integration of aquatic plant planting, aeration and stirring in the oxidation pond 2. It not only solves the problem of large floor space occupied when multiple oxidation ponds 2 are coordinated for aeration and stirring, but also stirs the water body while aerating the oxidation pond 2, thereby improving the uniformity of mixing of pollutants and microorganisms.

[0036] See also Figure 1 , Figure 2 and Figure 4 The sliding linkage group 51 includes rectangular grooves 510 and limiting grooves 511 respectively opened on the top and side walls of the oxidation pond 2 along its width direction. The plant planting rack 50 is fixedly installed with connecting frames 512 at both ends along its length direction. The connecting frames 512 are slidably connected to the limiting grooves 511 and the rectangular grooves 510 on the same side. Two adjacent connecting frames 512 are connected by a telescopic rod 513, and the telescopic rod 513 is located in the rectangular groove 510.

[0037] A sliding drive source (such as an electric slider) is installed on the connecting frame 512 on the side closest to the drainage pipe 3. Before the stirring and aerating mechanism 4 starts to aerate and stir the water body, the sliding drive source drives the connecting frame 512 connected thereto to move in a direction away from the drainage pipe 3, and multiple evenly arranged connecting frames 512 approach one after another, and the telescopic rod 513 contracts until the multiple connecting frames 512 are close to each other, thereby realizing the movement and folding of multiple plant planting racks 50, avoiding the formation of biofilms on the roots of plants by suspended matter and microorganisms in the water during aeration and stirring, affecting the growth and purification ability of the plants, and also facilitating the artificial addition of microorganisms to the oxidation pond 2.

[0038] After aeration and stirring in the oxidation pond 2, the sliding drive source drives the connecting frame 512 connected thereto to move toward the direction close to the drainage pipe 3, and multiple evenly arranged connecting frames 512 are gradually pulled apart in sequence, and the telescopic rod 513 is extended until multiple connecting frames 512 are spread out at equal distances, so that sunlight can be evenly irradiated into the oxidation pond 2, promoting the photosynthesis of algae in the oxidation pond 2, producing oxygen, and promoting the activity of aerobic microorganisms.

[0039] See also Figure 1 , Figure 2 , Figure 3 and Figure 4The mixing and aerating integrated mechanism 4 includes a plurality of pipe rectangular frames 41 arranged sequentially from top to bottom and connected and communicated through a plurality of support pipes 40. The pipe rectangular frame 41 is composed of a rectangular frame pipe and a plurality of connecting pipes evenly arranged along the width direction installed in the rectangular frame. The support pipe 40 is connected at the corners of two adjacent rectangular frame pipes. Aeration plates 42 evenly arranged and communicated with the pipe rectangular frame 41 are installed. The aeration plates 42 are staggered to further expand the aeration range of the aeration plates 42 when moving and the mixing of the water body when mixing. Range, a limiting guide group 43 for guiding the up and down movement along the corner of the oxidation pond 2 is installed on the support pipe 40 connected at the corner of two adjacent rectangular frame pipes, a gas transmission connection group 44 is installed between the inner wall of the oxidation pond 2 on the side away from the drainage pipe 3 and the multiple pipe rectangular frames 41, a lifting drive source (such as an electric slider or a hydraulic cylinder, not shown in the figure) for driving the pipe rectangular frames 41 to move up and down is installed on the oxidation pond 2, and a moving support guide group 45 for supporting and guiding the plant planting frame 50 is installed on the multiple pipe rectangular frames 41.

[0040] The gas delivery connection group 44 cooperates with the lifting drive source to intermittently deliver oxygen to the multiple pipe rectangular frames 41 and intermittently drive the multiple pipe rectangular frames 41 to move up and down reciprocatingly; when aerating the oxidation pond 2, the multiple plant planting racks 50 are first driven by the sliding linkage group 51 to move to one side of the gas delivery connection group 44 and retracted to avoid the formation of biofilm on the plant roots by suspended matter and microorganisms in the water during aeration and stirring, affecting the growth and purification ability of the plants, and also facilitating the artificial addition of microorganisms to the oxidation pond 2.

[0041] Then the gas delivery connection group 44 delivers oxygen to the multiple pipe rectangular frames 41 arranged from top to bottom. After the oxygen enters the pipe rectangular frames 41, it is injected into the water body through the aeration disk 42. When the oxygen enters the water body, it stirs the water body. The multiple rows of aeration disks 42 arranged from top to bottom inject oxygen into the water body at the same time, thereby avoiding the problem of poor purification effect of the oxidation pond 2 caused by uneven aeration. At the same time, the lifting drive source drives the pipe rectangular frame 41 to move back and forth up and down. During the reciprocating movement, the aeration disk 42 continuously aerates the water body, further improving the uniformity of aeration in the oxidation pond 2. The reciprocating movement of the pipe rectangular frame 41 can also stir the water body, so that the pollutants and microorganisms in the water body are fully and evenly mixed under the reciprocating movement and stirring of the pipe rectangular frame 41 and the stirring action of aeration, further improving the purification effect of the water body in the oxidation pond 2.

[0042] See also Figure 1 , Figure 2 , Figure 3 and Figure 4The limiting guide group 43 includes a fixing frame 430 fixedly sleeved on the support pipe 40, and a card wheel 431 is rotatably connected to the fixing frame 430. The card wheel 431 is an annular structure with a diameter gradually increasing from both ends to the middle, and the middle part of the card wheel 431 abuts against the corner of the inner wall of the oxidation pond 2. The card wheel 431 abuts against the corner of the inner wall of the oxidation pond 2 to guide the pipeline rectangular frame 41 when it moves up and down, and can also limit the pipeline rectangular frame 41 along its length and width directions to prevent the pipeline rectangular frame 41 from shaking at will and causing damage.

[0043] See also Figure 1 , Figure 3 and Figure 4 The gas delivery connection group 44 includes a main pipe 440 that is slidably connected to the side wall of the oxidation pond 2, and a connecting pipe 441 evenly arranged along the width direction is installed between two adjacent pipe rectangular frames 41 close to the main pipe 440. The connecting pipe 441 is connected to the main pipe 440 through a branch pipe 442.

[0044] The top of the main pipe 440 is connected to the existing aeration equipment gas delivery source through a telescopic pipe. When the stirring aeration integrated mechanism 4 moves up and down, the main pipe 440 moves synchronously with the pipeline rectangular frame 41 driven by the connecting pipe 441 and the branch pipe 442, and the telescopic pipe is extended and retracted accordingly. At the same time, the external aeration gas source delivers oxygen to the pipeline rectangular frame 41 through the telescopic pipe, the main pipe 440, the connecting pipe 441 and the branch pipe 442. Oxygen is introduced into the water through the aeration plate 42, thereby increasing the dissolved oxygen concentration in the water, which helps to remove harmful substances such as ammonia nitrogen and nitrite in the water. At the same time, aeration can also stir the water and promote the mixing of microorganisms in the water.

[0045] See also Figure 4 Except for a section close to the main pipe 440, the outer walls of the other three sections of the rectangular frame pipe are equipped with cleaning plates 410 for cleaning the inner wall of the oxidation pond 2. When the rectangular frame pipe moves up and down, the cleaning plates 410 clean the inner wall of the oxidation pond 2 to prevent pollutants or microorganisms from adhering to and accumulating on the inner wall of the oxidation pond 2 and affecting the mixing uniformity of the two.

[0046] See also Figure 1 , Figure 2 , Figure 3 and Figure 4The movable support guide group 45 comprises a support plate 450 installed between the middle parts of two sections arranged along the length direction of the rectangular frame pipe, and a guide slide groove 451 penetrating from top to bottom is provided on the support plate 450. A support limit rod 452 is installed in the middle part of the lower end surface of the plant planting frame 50. The support limit rod 452 slides through a plurality of guide slide grooves 451 arranged from top to bottom and then rotates to be connected to a rotating roller 453 that is in rolling contact with the inner wall of the bottom of the oxidation pond 2. The side wall of the support limit rod 452 is also installed with a rake assembly. The sliding linkage group 51 drives the plant When the planting rack 50 moves, the plant planting rack 50 drives the support limit rod 452 to move along the guide slot 451, and the support limit rod 452 cooperates with the guide slot 451 to guide the movement of the plant planting rack 50. The support limit rod 452 rolls with the inner wall of the bottom of the oxidation pond 2 through the rotating roller 453, thereby supporting the middle part of the plant planting rack 50, avoiding the problem that the plant planting rack 50 spans between the two side walls in the width direction of the oxidation pond 2, and the middle part of the plant planting rack 50 is suspended for a long time and deformed or broken.

[0047] In addition, when the rectangular frame pipe moves up and down, the support limit rod 452 cooperates with the guide slide groove 451 to guide and limit the rectangular frame pipe.

[0048] See also Figure 1 and Figure 2 The raking assembly includes a rack 454 connected to a support limit rod 452 through a fixed bar. The rack 454 is in close contact with the side wall of the rotating roller 453 and the bottom of the rack 454 is close to the bottom inner wall of the oxidation pond 2. The rack 454 moves with the support limit rod 452 to scrape up the sediment deposited at the bottom of the oxidation pond 2, thereby avoiding the problem that microorganisms (such as algae, etc.) deposited at the bottom of the oxidation pond 2 hinder the rotation of the rotating roller 453.

[0049] See also Figure 1 and Figure 2 The bottom of the inner wall of the oxidation pond 2 is horizontally slidably connected to one side of the drainage pipe 3, and the scraper 20 is evenly arranged along the length direction of the oxidation pond 2. A swing rod 21 is hinged between the scraper 20 and the support pipe 40 located at the lowest side. In the process of the pipe rectangular frame 41 moving up and down, the pipe rectangular frame 41 drives the scraper 20 to move horizontally through the swing rod 21 to scrape up a small amount of sediment at the bottom of the inner wall of the oxidation pond 2, further stir the water body, and cooperate with the raking component to fully clean up the small amount of sediment at the bottom of the inner wall of the oxidation pond 2 to avoid accumulation of sediment.

[0050] See also Figure 1-Figure 5The present invention also provides an ecological oxidation pond treatment process for livestock and poultry wastewater, comprising the following steps: S1, wastewater sedimentation: livestock and poultry wastewater is discharged into a grid sedimentation tank 1, which removes larger suspended matter and floating matter and heavier inorganic particulate matter in the livestock and poultry wastewater. After the wastewater is precipitated and impurities are removed in the grid sedimentation tank 1, it enters the oxidation pond 2, and the aquatic plants planted in the plant planting rack 50 absorb nutrients in the wastewater through their roots.

[0051] S2, aeration operation: The sliding drive source drives the connecting frame 512 connected thereto to move away from the drainage pipe 3, and multiple evenly arranged connecting frames 512 approach one by one, and the telescopic rod 513 contracts until the multiple connecting frames 512 are close to each other, thereby realizing the movement and folding of multiple plant planting frames 50 to prepare for the aeration of the water body in the oxidation pond 2; then, the gas delivery connection group 44 cooperates with the lifting drive source to deliver oxygen to the multiple pipe rectangular frames 41 and intermittently drive the multiple pipe rectangular frames 41 to move up and down, and oxygen enters. After entering the pipe rectangular frame 41, oxygen is injected into the water body through the aeration plate 42. When the oxygen enters the water body, the water body is stirred. The multiple rows of aeration plates 42 arranged from top to bottom inject oxygen into the water body at the same time, and the aeration plates 42 continuously aerate the water body during the reciprocating movement of the pipe rectangular frame 41, thereby further improving the uniformity of aeration of the oxidation pond 2. The reciprocating movement of the pipe rectangular frame 41 also stirs the water body, not only aerating the water bodies at different depths in the oxidation pond 2, but also stirring the water body in the oxidation pond 2.

[0052] S3, cycle processing: after aeration is completed, the gas delivery connection group 44 and the lifting drive source are stopped, and the sliding linkage group 51 is started to unfold the multiple plant planting racks 50; when aeration is needed again after a period of time, the above S2 step is repeated.
