Description

Technical Field

[0001] The invention relates to the technical field of aquaculture wastewater treatment, and in particular to a membrane separation device for livestock and poultry aquaculture wastewater. Background Art

[0002] The amount of wastewater discharged from livestock and poultry farming is large and concentrated, and the wastewater contains a large number of pollutants, such as heavy metals, residual veterinary drugs and a large number of pathogens. Therefore, if it is discharged into the environment or directly used for agricultural purposes without treatment, it will cause serious pollution to the local ecological environment and farmland. Livestock and poultry farming wastewater is a high-concentration organic wastewater rich in a large number of pathogens. If it is directly discharged into the water body or stored in an inappropriate place, it will be washed into the water body by rainwater, which may cause serious deterioration of the quality of surface water or groundwater. Since livestock and poultry manure and urine are highly leached, the leaching amount of nitrogen, phosphorus and water-soluble organic matter in the manure and urine is very large. If it is not properly handled, it will enter the groundwater layer through surface runoff and infiltration and pollute the groundwater.

[0003] After searching, patent publication number CN214218497U proposes a membrane device for treating livestock and poultry wastewater, including an anaerobic box, a treatment box is welded and fixed on one side of the anaerobic box, four support rods arranged in a matrix are welded and fixed on the top of the anaerobic box, and a mounting frame is fixed between the four support rods.

[0025] It should be noted that when the adjusting sleeve 53 slides on the side wall of the reciprocating threaded groove rod 51, the adjusting sleeve 53 can drive the rack 58 to move forward and backward, and the rack 58 is meshed with the gear 57. At this time, the gears 57 on the left and right sides will drive the transmission rod 56 to rotate the worm 63. At this time, when the gear 57 moves forward and backward, it can drive the worm 63 to rotate the worm wheel 62 forward and reverse. Since the worm wheel 62 is fixedly connected to the rotating disk 64 through the support rod 61, the rotating disk 64 will drive the extension frame 65 to rotate forward and reverse. The stirring plate 66 is inclined. With the continuous rotation of the rotating disk 64, the stirring plate 66 can achieve the mixing of the wastewater and the deodorant in the mixing box 1.

[0026] Furthermore, the liquid adding assembly 7 comprises a cam block 71 fixedly mounted on the rear end face of the reciprocating thread groove rod 51, and a pressure storage box 72 fixedly mounted on the side wall of the mixing box 1, a piston plate 73 is slidably mounted in the inner cavity of the pressure storage box 72, a sliding rod 74 is fixedly mounted on the side wall of the piston plate 73, a return spring 75 is wound around the side wall of the sliding rod 74, and a liquid storage box 76 is fixedly mounted on the right side of the upper end face of the mixing box 1; One end of the return spring 75 is fixedly mounted on the side wall of the piston plate 73, and the other end of the return spring 75 is fixedly mounted on the inner cavity side wall of the pressure accumulator box 72. The sliding rod 74 is slidably connected to the pressure accumulator box 72, and the sliding rod 74 is tightly pressed against the side wall of the cam block 71. The inner cavities of the pressure accumulator box 72 and the liquid storage box 76 are filled with a deodorant, and the deodorant is composed of one or a combination of hydrogen peroxide or sodium hypochlorite. The pressure accumulation box 72 is fixedly connected to the liquid storage box 76 through the liquid inlet pipe 761, and the pressure accumulation box 72 is fixedly connected to the scraper frame 54 through the liquid outlet pipe 721. A one-way water valve with its outlet to the inner cavity of the pressure accumulation box 72 is provided at the connection point between the liquid inlet pipe 761 and the pressure accumulation box 72, and a one-way water valve with its outlet to the inner cavity of the liquid outlet pipe 721 is provided at the connection point between the liquid outlet pipe 721 and the pressure accumulation box 72. The liquid outlet pipe 721 is made of a corrugated hose, and an end is provided on the side wall of the scraper frame 54.

[0027] When the piston plate 73 moves toward the left side of the inner cavity of the pressure accumulator box 72, the deodorant in the inner cavity of the liquid storage box 76 can enter the right inner cavity of the pressure accumulator box 72 through the liquid inlet pipe 761 to increase the capacity of the deodorant in the right cavity of the pressure accumulator box 72, and when the piston plate 73 moves toward the right side of the inner cavity of the pressure accumulator box 72, the volume of the right cavity of the pressure accumulator box 72 is reduced, and the deodorant in the right cavity of the pressure accumulator box 72 can enter the scraper frame 54 through the liquid outlet pipe 721, and finally be discharged from the end on the side wall of the scraper frame 54 into the mixing box 1. At this time, the entire device can realize the function of adding deodorant to the mixing box 1 in batches.

[0028] Furthermore, the purification component 8 includes a water pump 81 fixedly mounted on the front side wall of the inner cavity of the mixing box 1, and a pressure pipe 82 rotatably mounted in the inner cavity of the separation box 2, an MBR filter membrane block 83 is fixedly mounted on the side wall of the pressure pipe 82, the pressure pipe 82 is connected to the MBR filter membrane block 83, and the output end of the water pump 81 is connected to the pressure pipe 82 via a connecting pipe 84.

[0029] It should be noted that after the wastewater in the mixing box 1 is preliminarily mixed, the user can start the water pump 81 to allow the wastewater in the mixing box 1 to enter the pressure pipe 82 through the connecting pipe 84. Under the action of the high pressure in the pressure pipe 82, the MBR filter membrane block 83 can intercept the active microorganisms and macromolecular organic matter in the wastewater, thereby purifying the wastewater. After that, the wastewater can continuously precipitate out of the MBR filter membrane block 83 and settle in the separation box 2.

[0030] Working principle: After the user adds livestock and poultry wastewater into the mixing box 1, the reciprocating threaded groove rod 51 is rotated by starting the driving motor 55, and the cam block 71 fixedly installed at the rear end of the reciprocating threaded groove rod 51 will also rotate. Since the cam block 71 is tightly pressed against the side wall of the sliding rod 74, the cam block 71 can squeeze the sliding rod 74 to drive the piston plate 73 to slide in the inner cavity of the pressure accumulator box 72. When the piston plate 73 moves toward the left side of the inner cavity of the pressure accumulator box 72, the deodorant in the inner cavity of the liquid storage box 76 can be discharged through the inlet. The liquid pipe 761 enters the right inner cavity of the pressure accumulator box 72 to increase the capacity of the deodorant in the right cavity of the pressure accumulator box 72. When the piston plate 73 moves toward the right side of the inner cavity of the pressure accumulator box 72, the volume of the right cavity of the pressure accumulator box 72 is reduced, and the deodorant in the right cavity of the pressure accumulator box 72 can enter the scraper frame 54 through the liquid outlet pipe 721, and finally be discharged from the end on the side wall of the scraper frame 54 into the mixing box 1. At this time, the whole device can realize the function of adding deodorant to the mixing box 1 in batches for multiple times. When the reciprocating threaded groove rod 51 rotates, the regulating sleeve 53 can drive the scraping frame 54 to move forward and backward in the inner cavity of the mixing box 1 under the cooperation of the limiting pins 531 on the inner wall of the adjusting sleeve 53, so as to scrape off the livestock and poultry waste residue adhering to the inner wall of the mixing box 1, thereby improving the quality of the whole device for mixing wastewater and deodorant; When the adjusting sleeve 53 slides on the side wall of the reciprocating thread groove rod 51, the adjusting sleeve 53 can drive the rack 58 to move forward and backward, and the rack 58 is meshed with the gear 57. At this time, the gears 57 on the left and right sides will drive the transmission rod 56 to rotate the worm 63. At this time, when the gear 57 moves forward and backward, the worm 63 can be driven to rotate the worm wheel 62 forward and reversely. Since the worm wheel 62 is fixedly connected to the rotating disk 64 through the support rod 61, the rotating disk 64 will drive the extension frame 65 to rotate forward and reversely. The stirring plate 66 is arranged at an angle. With the continuous rotation of the rotating disk 64, the stirring plate 66 can achieve mixing of the wastewater and the deodorant in the mixing box 1; When the extension frame 65 rotates, under the centrifugal force of the stirring plate 66, the slider 652 can squeeze the centrifugal spring 653 to move toward the outer side of the inner cavity of the extension frame 65, so that the multiple groups of stirring plates 66 are separated from each other, thereby increasing the stirring range of the stirring plates 66. When the rack 58 is reversed, the extension frame 65 will stop rotating. At this time, under the pulling force of the centrifugal spring 653, the slider 652 can be restored to the initial position of the inner cavity of the extension frame 65, so that the stirring range of the stirring plate 66 is reduced to increase the contact area between the wastewater and the deodorant. Therefore, through the above, the device can realize the function of adaptively changing the stirring range of the stirring plate 66 and stirring the wastewater in the forward and reverse directions, and when the scraper frame 54 is displaced, the deodorant can be added to the mixing box 1 in batches and multiple times and at different positions, which greatly improves the efficiency of the whole device in stirring and mixing the wastewater and improves the practicality of the whole device. After the wastewater in the mixing box 1 is preliminarily mixed, the user can start the water pump 81 to allow the wastewater in the mixing box 1 to enter the pressure pipe 82 through the connecting pipe 84. Under the action of the high pressure in the pressure pipe 82, the MBR filter membrane block 83 can intercept the active microorganisms and macromolecular organic matter in the wastewater, so that the wastewater is purified. After that, the wastewater can continuously precipitate out of the MBR filter membrane block 83 and settle in the separation box 2. At this time, the device solves the problems of the current aquaculture wastewater treatment device with complex structure, high production cost, poor treatment effect, and a large amount of floating objects mixed in the treated wastewater.

[0031] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Simple modifications or equivalent substitutions of the technical solution of the present invention by ordinary technicians in this field do not deviate from the essence and scope of the technical solution of the present invention.
