Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment devices, and particularly to a sewage treatment device for chicken farms. Background Art

[0002] During the operation of modern chicken farms, a large amount of sewage mainly comes from chicken coop flushing, wastewater generated during the breeding process, and pollutants carried by rainwater. This sewage usually contains high concentrations of nitrogen, phosphorus, organic matter, and pathogenic microorganisms. If discharged without effective treatment, it will cause serious pollution to the environment, such as water eutrophication, soil pollution, and groundwater resource pollution, etc.

[0003] For example, a sewage treatment device for chicken farms in "CN108059296A" includes a noise-proof housing. One end of the noise-proof housing is provided with a water inlet. A grid tank is arranged on one side of the noise-proof housing near the water inlet. A grid is installed above the interior of the grid tank. A cleaning plate is rotatably connected to the noise-proof housing through a damping rotating shaft at a position below the water inlet. The outer side of the cleaning plate is fixedly connected to a clamping ring through a clamping column, and the clamping ring is fixedly connected to the noise-proof housing by welding. In the present invention, a cleaning plate is rotatably connected to the grid tank through a damping rotating shaft. When it is necessary to clean the sundries at the grid in the grid tank, only the clamping column needs to be taken out, and the cleaning plate is rotated to a certain angle through the damping rotating shaft, then the sundries can be easily cleaned out, preventing the sundries from blocking the grid and affecting the treatment efficiency. And a sealing ring is arranged at the connection position between the cleaning plate and the noise-proof housing to prevent internal sewage leakage.

[0004] However, in the prior art, in scenarios such as chicken coop flushing or other high-intensity water use scenarios, the concentration of pollutants in the sewage will soar instantaneously, which easily causes the sewage treatment system to be difficult to adapt to this high load in a short period of time, thus affecting the treatment effect. During the sewage treatment process, it is possible that because the pollutants in the sewage are not processed in time, the sewage is discharged, resulting in a significant reduction in the quality of sewage treatment. Summary of the Invention

[0005] In view of the above existing problems, the present invention is proposed.

[0006] The purpose of the present invention is to solve the problem in the prior art that in scenarios such as chicken coop flushing or other high-intensity water use scenarios, the concentration of pollutants in the sewage will soar instantaneously, and if directly treated, it will reduce the treatment effect of the sewage.

[0007] To solve the above technical problems, the present invention provides the following technical solutions:

[0008] On the one hand, the present invention provides a sewage treatment device for a chicken farm, which includes an inlet tank and a treatment tank. The output end of the inlet tank is communicated with the inlet end of the treatment tank. Above the interior of the inlet tank, there is a floating rack. At the upper end inside the floating rack, there is a drainage frame. Inside the floating rack below the drainage frame, there are successively arranged a porous layer and an activated carbon layer from top to bottom. On the outer wall of the floating rack facing the outlet of the inlet tank, there is a biological layer. Inside the inlet tank below the floating rack, a first conveyor belt is rotatably arranged. On the outer wall of the first conveyor belt, there are guiding strips. Below the interior of the inlet tank, there is a gas pipe laid, and spray heads are communicated with the gas pipe. Above the side wall of the inlet tank, there is a foam trough. On both sides of the inlet tank, auxiliary tanks are respectively communicated. At the upper end of the inlet tank, there are multiple water inlet pipes. The end face of the water inlet pipe extends above the drainage frame. On the end face of the water inlet pipe, a sewage discharge rack is rotatably arranged. On the side wall of the sewage discharge rack, there are multiple filter pipes communicated with the end face of the water inlet pipe. Above the water inlet pipe, there is a sewage discharge pipe communicated with the filter pipe. The sewage discharge rack is driven to rotate by a motor.

[0009] Further, one porous layer and one activated carbon layer are taken as a group and there are multiple groups in total. The activated carbon layer is arranged below the porous layer. The activated carbon layer is an activated carbon fiber felt. By arranging multiple groups of the porous layer and the activated carbon layer, the rapid adsorption of substances in the sewage can be increased. Among them, the porous layer is made of corrosion-resistant high-molecular polyethylene material, and the activated carbon layer is a fiber material with relatively high adsorption capacity, which can initially adsorb suspended substances and particulate matters.

[0010] Further, the biological layer is porous. Activated carbon particles are embedded inside the biological layer. An attachment layer is arranged on the outer wall of the biological layer. Through the porous design and the attachment layer, it is convenient for bacteria to better attach to the surface of the biological layer. Among them, the attachment layer can specifically be a nanofiber membrane. By embedding activated carbon particles, the substances in the sewage can be attached to the activated carbon particles for better absorption by bacteria. At the same time, since the biological layer is at the air flow position, part of the air flow can wash away the bacteria that have multiplied excessively.

[0011] Further, installation strips are arranged on both sides of the biological layer. Installation grooves are symmetrically arranged on both sides of the inner wall of the inlet tank. The installation strips are engaged and slidably arranged with the installation grooves. Through the adaptation of the installation grooves and the installation strips, it is convenient to disassemble and replace the biological layer.

[0012] Further, multiple filter pipes are arranged and uniformly communicated on the side wall of the sewage discharge rack. The water outlet end of the water inlet pipe is arranged downward and is closely attached to the lower part of the inner wall of the sewage discharge rack. A filling plug is arranged on the outer wall of the end face of the water inlet pipe. The inner wall of the sewage discharge rack and the outer wall of the filling plug are hermetically slidably arranged. One end of the sewage discharge pipe is arranged above the filling plug and is hermetically communicated with the end face of the upper filter pipe.

[0013] Further, the output ends of each of the water inlet pipes are located above the drainage frame and are staggered in the horizontal direction. A fixing frame is provided above the end face of the water inlet tank away from the water inlet pipe. A rotating shaft is rotatably penetrated through the fixing frame. One end of the rotating shaft is linked with the center of the sewage discharge frame. Adjacent rotating shafts are linked inside the fixing frame. One end face of a rotating shaft is driven to rotate by a motor. By driving the motor to rotate, the rotating shaft is driven to rotate, and then all the sewage discharge frames are driven to rotate, realizing the switching of the filter pipes. Specifically, when a filter pipe stores dirt for a period of time, the filter pipe can be switched. A new filter pipe is replaced and communicated with the water inlet pipe. The filter pipe with dirt rotates to the upper part and falls into the sewage discharge pipe under the action of gravity for discharge.

[0014] Further, a net bag is provided on the inner wall of the end face of the filter pipe. The net bag is only assembled and connected to the inner wall of the filter pipe at the edge. A support frame is provided at the center position of the upper end of the water inlet tank. A cleaning pipe is provided below the support frame. A third water pump is provided on the outer wall of the water inlet tank. One end of the cleaning pipe is communicated with the lower part inside the water inlet tank through the third water pump, and a plurality of water outlet heads are communicated and provided on the side wall of the other end. The output end of the water outlet head faces the end face of the uppermost filter pipe. When the filter pipe carrying dirt rotates to the upper end, the net bag is separated from the end face of the filter pipe under the action of gravity and is only connected to the filter pipe at the edge. The dirt pulls the net bag to deform, making it easier for the dirt to separate from the net bag and fall into the sewage discharge pipe. The third water pump is started to flush a part of sewage towards the end face of the filter pipe through the water outlet head, which can better separate the dirt from the net bag. With the lubrication of water, the dirt can smoothly slide away in the sewage discharge pipe.

[0015] Further, a sewage storage tank is provided on the outer wall of the water inlet tank. One end of the sewage discharge pipe extends into the sewage storage tank. A floating foam pool is provided on the outer wall of the water inlet tank at the floating foam trough. The output end of the floating foam pool is communicated with the sewage storage tank.

[0016] Further, a second conveyor belt is provided above the inner part of the water inlet tank on one side of the floating frame. Drainage strips are provided on the second conveyor belt. A triangular seat is provided on the inner wall of the water inlet tank below the floating foam trough. By providing the triangular seat, the floating foam can be drained towards the second conveyor belt, and the drainage strips on the second conveyor belt can drain the floating foam above the triangular seat until it is discharged from the floating foam trough. The drainage strips are made of soft materials.

[0017] Further, a first water pump and a second water pump are respectively communicated and provided on the auxiliary pool and the water inlet tank. The output end of the first water pump is communicated with the water inlet tank through a first water pipe. The output end of the second water pump is communicated with the treatment pool through a second water pipe. The lower part of the side wall of the water inlet tank is communicated with the auxiliary pool through a distribution pipe. A valve body is provided on the distribution pipe.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. When the sewage of the present invention passes through the porous layer and the activated carbon layer, the suspended solids and particulate matters in the sewage are rapidly adsorbed on the porous layer and the activated carbon layer. Only a part of the substances flow into the treatment tank with the sewage for sewage treatment. Among them, the substances adsorbed on the porous layer and the activated carbon layer remain in the sewage of the inlet tank all the time. These substances will be continuously and slowly released into the sewage of the inlet tank over time and enter the treatment tank along the water flow direction for sewage treatment. This can effectively reduce the situation that during a single drainage process, the sewage directly flushes into the treatment tank, resulting in a significant reduction in the sewage treatment effect in the treatment tank. By slowly releasing the substances in the sewage and then entering the treatment tank, the substances in the sewage can be treated more fully.

[0020] 2. When the amount of sewage discharged at one time is large in the present invention, the sewage can be introduced into the auxiliary tanks on both sides to reduce the water storage pressure of the inlet tank. When the water volume in the inlet tank decreases, it can be re-introduced back into the inlet tank.

[0021] 3. An air pipe and a nozzle are arranged at the bottom of the inlet tank in the present invention, and gas can be flushed into the inlet tank from bottom to top. The generated bubbles can wrap the particulate matters in the sewage and increase their buoyancy, making the floating substances float and be discharged from the foam trough. Among them, the air pipe is connected to an external air pump, and the particulate matters passing through the porous layer and the activated carbon layer and entering the lower end of the floating rack are led to the water outlet end of the inlet tank under the rotation and diversion of the first conveyor belt, avoiding the accumulation of substances at the bottom of the floating rack. Cooperating with the bubbles generated by the nozzle, the particulate impurities can be led out faster, achieving the effect of pre-treating the sewage.

[0022] 4. Through the biological layer provided in the present invention, some substances in the sewage can be absorbed, further achieving the effect of pre-treatment. BRIEF DESCRIPTION OF THE DRAWINGS

The output end of the inlet tank 1 is communicatively connected to the inlet end of the treatment tank 2. Above the interior of the inlet tank 1, there is a floating frame 3. At the upper end inside the floating frame 3, there is a drainage frame 4. Below the drainage frame 4 in the floating frame 3, there are a porous layer 5 and an activated carbon layer 6 arranged successively from top to bottom. On the outer wall of the floating frame 3 facing the outlet of the inlet tank 1, there is a biological layer 7. Rotatably arranged on the inner wall of the inlet tank 1 below the floating frame 3 is a first conveyor belt 811. On the outer wall of the first conveyor belt 811, there are guiding strips 812. Below the interior of the inlet tank 1, there is an air pipe 911 laid, and communicating with the air pipe 911 are spray nozzles 912. Above the side wall of the inlet tank 1, there is a foam trough 10. On both sides of the inlet tank 1, there are auxiliary tanks 11 communicatively connected respectively. At the upper end of the inlet tank 1, there are a plurality of inlet pipes 121. The end face of the inlet pipe 121 extends above the drainage frame 4. Rotatably arranged on the end face of the inlet pipe 121 is a sewage discharge frame 122. On the side wall of the sewage discharge frame 122, there are a plurality of filter pipes 123 communicatively connected to the end face of the inlet pipe 121. Above the inlet pipe 121, there is a sewage discharge pipe 124 communicatively connected to the filter pipe 123. The sewage discharge frame 122 is driven to rotate by a motor 13.

[0038] As Figures 1 - 8 shown, one porous layer 5 and one activated carbon layer 6 form a group and there are multiple groups in total. The activated carbon layer 6 is arranged below the porous layer 5. The activated carbon layer 6 is an activated carbon fiber felt. By arranging multiple groups of the porous layer 5 and the activated carbon layer 6, the rapid adsorption of substances in the sewage can be increased. Among them, the porous layer 5 is made of corrosion-resistant high molecular polyethylene material, and the activated carbon layer 6 is a fiber material with relatively high adsorption capacity, which can initially adsorb suspended solids and particulate matters.

[0039] As Figures 1 - 8 shown, the biological layer 7 is porous. Inside the biological layer 7, there are embedded activated carbon particles 141. On the outer wall of the biological layer 7, there is an attachment layer 142. Through the porous design and the attachment layer 142, it is convenient for bacteria to better attach to the surface of the biological layer 7. Among them, the attachment layer 142 can specifically be a nanofiber membrane. By embedding the activated carbon particles 141, the substances in the sewage can be attached to the activated carbon particles 141 for better absorption by bacteria. At the same time, the biological layer 7 is at the air flow position, and part of the air flow can wash away the bacteria that have multiplied excessively.

[0040] As Figures 1 - 8As shown, mounting strips 151 are provided on both sides of the biological layer 7. Mounting grooves 152 are symmetrically provided on both inner walls of the water inlet tank 1. The mounting strips 151 are engaged and slidably arranged with the mounting grooves 152. Through the adaptation of the mounting grooves 152 and the mounting strips 151, it is convenient to disassemble and replace the biological layer 7.

[0041] As Figures 1 - 8 shown, a plurality of filter pipes 123 are provided and are uniformly connected to the side wall of the sewage discharge rack 122. The water outlet end of the water inlet pipe 121 is arranged downward and is in close contact with the lower part of the inner wall of the sewage discharge rack 122. A filling plug 16 is provided on the outer wall of the end face of the water inlet pipe 121. The inner wall of the sewage discharge rack 122 and the outer wall of the filling plug 16 are hermetically slidably arranged. One end of the sewage discharge pipe 124 is arranged above the filling plug 16 and is hermetically connected to the end face of the uppermost filter pipe 123.

[0042] As Figures 1 - 8 shown, the output ends of each water inlet pipe 121 are all located above the drainage frame 4 and are staggered in the horizontal direction. A fixing frame 171 is provided above the end face of the water inlet tank 1 far from the water inlet pipe 121. A rotating shaft 172 is rotatably penetrated through the fixing frame 171. One end of the rotating shaft 172 is linked to the center of the sewage discharge rack 122. Adjacent rotating shafts 172 are linked within the fixing frame 171. One end face of a rotating shaft 172 is driven to rotate by a motor 13. By driving the motor 13 to rotate, the rotating shaft 172 is driven to rotate, and then all the sewage discharge racks 122 are driven to rotate, realizing the switching of the filter pipes 123. Specifically, when a filter pipe 123 stores dirt for a period of time, the filter pipe 123 can be switched. A new filter pipe 123 is replaced and connected to the water inlet pipe 121, and the filter pipe 123 with dirt rotates to the upper part and falls into the sewage discharge pipe 124 under the action of gravity for discharge.

[0043] As Figures 1 - 8 shown, a net pocket 181 is provided on the inner wall of the end face of the filter pipe 123. The net pocket 181 is only assembled and connected to the inner wall of the filter pipe 123 at the edge. A support frame 182 is provided at the center position of the upper end of the water inlet tank 1. A cleaning pipe 183 is provided below the support frame 182. One end of the cleaning pipe 183 is connected to the lower part inside the water inlet tank 1 through a third water pump 184, and a plurality of water outlet heads 185 are communicated and arranged on the side wall of the other end. The output end of the water outlet head 185 faces the end face of the uppermost filter pipe 123. When the filter pipe 123 carrying dirt rotates to the upper end, the net pocket 181 is separated from the end face of the filter pipe 123 under the action of gravity and is only connected to the filter pipe 123 at the edge. The dirt pulls the net pocket 181 to deform, making it easier for the dirt to separate from the net pocket 181 and fall into the sewage discharge pipe 124. The third water pump 184 is started to flush a part of the sewage from the water outlet heads 185 to the end face of the filter pipe 123, which can better separate the dirt from the net pocket 181. With the lubrication of water, the dirt can smoothly slide away in the sewage discharge pipe 124.

[0044] AsFigures 1 - 8 As shown, a sewage storage pool 191 is provided on the outer wall of the water inlet pool 1. One end of the sewage discharge pipe 124 extends into the sewage storage pool 191. A floating foam pool 192 is provided on the outer wall of the water inlet pool 1 at the floating foam trough 10. The output end of the floating foam pool 192 is communicated with the sewage storage pool 191.

[0045] As Figures 1 - 8 shown, a second conveyor belt 20 is provided above the interior of the water inlet pool 1 on one side of the floating rack 3. Drainage strips 21 are provided on the second conveyor belt 20. A triangular seat 22 is provided on the inner wall of the water inlet pool 1 below the floating foam trough 10. Through the provided triangular seat 22, the floating foam can be drained towards the second conveyor belt 20, and the drainage strips 21 on the second conveyor belt 20 can drain the floating foam above the triangular seat 22 until it is discharged from the floating foam trough 10. Among them, the drainage strips 21 are made of soft materials.

[0046] As Figures 1 - 8 shown, a first water pump 23 and a second water pump 24 are respectively communicated and provided on the auxiliary pool 11 and the water inlet pool 1. The output end of the first water pump 23 is communicated with the water inlet pool 1 through a first water pipe 25. The output end of the second water pump 24 is communicated with the treatment pool 2 through a second water pipe 26. The lower part of the side wall of the water inlet pool 1 is communicated with the auxiliary pool 11 through a distribution pipe 27. A valve body is provided on the distribution pipe 27.

[0047] Working principle: When treating sewage, the sewage is discharged into the water inlet tank 1 through the water inlet pipe 121. After the sewage first exits the water inlet pipe 121, it enters a corresponding filter pipe 123 of the sewage discharge rack 122. Large particulate impurities or feathers, weeds, etc. in the sewage can be left in the filter pipe 123. The filtered sewage then passes through the diversion frame 4 and enters the floating rack 3, and successively passes through the porous layer 5 and the activated carbon layer 6 and enters the interior of the water inlet tank 1. When the sewage is first discharged into the interior of the water inlet tank 1, the concentration of the sewage entering the water inlet tank 1 is the highest. At this time, when the sewage passes through the porous layer 5 and the activated carbon layer 6, the suspended substances and particulate matters in the sewage are quickly adsorbed on the porous layer 5 and the activated carbon layer 6. Only a part of the substances flow into the treatment tank 2 with the sewage for sewage treatment. Among them, the substances adsorbed on the porous layer 5 and the activated carbon layer 6 have been in the sewage in the water inlet tank 1. These substances will be continuously and slowly released into the sewage in the water inlet tank 1 over time and enter the treatment tank 2 with the water flow direction for sewage treatment. This can effectively reduce the situation that in the process of one-time drainage, the sewage directly flushes into the treatment tank 2, resulting in a significant reduction in the sewage treatment effect in the treatment tank 2. By slowly releasing the substances in the sewage and then entering the treatment tank 2, the substances in the sewage can be treated more fully. In addition, when the amount of sewage discharged at one time is large, the sewage can be introduced into the auxiliary tanks 11 on both sides to reduce the water storage pressure of the water inlet tank 1. When the water volume in the water inlet tank 1 decreases, it can be re-introduced back into the water inlet tank 1. An air pipe 911 and a nozzle 912 are arranged at the bottom of the water inlet tank 1, and gas can be flushed into the water inlet tank 1 from bottom to top. The generated bubbles can wrap the particulate matters in the sewage and increase their buoyancy, making the floating substances float and discharged from the floating foam trough 10. Among them, the air pipe 911 is connected to an external air pump, and the particulate matters passing through the porous layer 5 and the activated carbon layer 6 and entering the lower end of the floating rack 3 are led out to the water outlet end of the water inlet tank 1 under the rotation and diversion of the first conveyor belt 811, avoiding the accumulation of substances at the bottom of the floating rack 3. The bubbles generated in cooperation with the nozzle 912 can lead out the particulate impurities in it faster, achieving the effect of pre-treating the sewage. By setting the biological layer 7, some substances in the sewage can be absorbed, further achieving the effect of pre-treatment.
