[0018] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0019] The present invention provides a pig farm saprophytic filtration sewage treatment system based on recycling, such as Figures 1 to 5 As shown, it includes a black film biogas tank 1, one side of the black film biogas tank 1 is provided with an aeration device, and one side of the aeration device is provided with a filtering and purification device; The aeration equipment includes: a bottom plate 2, an aeration tank 3, a geomembrane 4, a ring plate 5, a lifting plate 6, a cylinder 7, a lifting assembly for driving the ring plate 5 to rise and fall, and an aeration pipe installation pipeline 8; The aeration tank 3 is fixed on the top of the bottom plate 2, the geomembrane 4 is laid inside the aeration tank 3, the geomembrane 4 is a high-density polyethylene geomembrane, the ring plate 5 is sleeved on the outside of the aeration tank 3 and is fixedly connected to the top of the geomembrane 4, the lifting plate 6 is arranged on the bottom wall of the aeration tank 3, the cylinder 7 is fixed on the top of the bottom plate 2 and its cylinder rod is fixedly connected to the lifting plate 6, and the cylinder 7 is a multi-section cylinder.

[0020] When in use, sewage is introduced into the black film biogas tank 1 to decompose organic matter, and the treated sewage is introduced into the aeration tank 3 to combine with the activated sludge put into the aeration tank 3 to decompose the organic matter in the sewage into harmless substances such as carbon dioxide and water, thereby purifying the sewage. At the same time, aeration is performed through the aeration pipe installation pipeline 8 to improve the reaction effect. The treated sewage is introduced into the filtering and purification equipment for filtering and purification, and finally discharged, thereby achieving the treatment of sewage so that it can be recycled for use; When it is necessary to clean the geomembrane 4 in the aeration tank 3, the sewage in the aeration tank 3 is pumped out, the cylinder 7 is started to extend its cylinder rod to lift the lifting plate 6, thereby dragging the geomembrane 4 up, and at the same time, the ring plate 5 is driven to descend through the lifting assembly, and the end of the geomembrane 4 connected to it is pulled down accordingly, so that the geomembrane 4 is gradually wrapped around the outside of the aeration tank 3, and finally the lifting plate 6 is located at the top of the aeration tank 3, and the geomembrane 4 with the dirt inside it is located on the outside of the aeration tank 3, which makes it easy to clean the dirt, and with the rise of the lifting plate 6, the harmful gas in the aeration tank 3 is discharged to the outside, so that when cleaning the aeration tank 3 later, there is no need to spend a lot of time waiting for the emission of harmful gases in the aeration tank 3 to disappear, thereby improving the cleaning efficiency, and through the above operation, when cleaning the geomembrane 4 in the aeration tank 3, there is no need to enter the aeration tank 3, and the geomembrane 4 can be cleaned, saving time and effort.

[0021] like Figure 3 to Figure 4 As shown, the lifting assembly includes: a pair of sliders 9, a first spring 10, a pull rope 11, a pair of motors 12 and a take-up drum 13; A pair of sliders 9 are symmetrically fixed on the inner side of the ring plate 5, and slide grooves are symmetrically opened on the outer side of the aeration tank 3. The sliders 9 are slidably set in the slide grooves. The two ends of the first spring 10 are respectively fixedly connected to the sliders 9 and the bottom wall of the slide groove. One end of the pull rope 11 is fixed to the bottom of the slider 9, the motor 12 is fixed to the top of the bottom plate 2, the take-up drum 13 is fixed on the output shaft of the motor 12, and the bottom end of the pull rope 11 is fixedly connected to the take-up drum 13.

[0022] Starting the motor 12 causes its output shaft to rotate forward with the take-up drum 13, so that the take-up rope 11 is wound up, thereby pulling the slider 9 and the ring plate 5 down, and then driving the ring plate 5. When the slider 9 descends, the first spring 10 is compressed to deform and generate a force. Conversely, starting the motor 12 causes its output shaft to reverse, so that the take-up drum 13 reverses to release the rope 11, and the first spring 10 releases the force to carry the slider 9 and the ring plate 5 up.

[0023] like Figure 3 As shown, a wire-passing hole is provided on the bottom wall of the slide slot, and the pull rope 11 is located inside the first spring 10 and passes through the wire-passing hole.

[0024] like Figures 3 to 5As shown, an annular groove 14 is provided at the inner upper part of the aeration tank 3 , and a beating assembly for beating the geomembrane 4 is provided in the annular groove 14 .

[0025] During use, dirt will accumulate on the inner side of the geomembrane 4. If too much dirt accumulates somewhere on the geomembrane 4, when the geomembrane 4 is pulled by the ring plate 5 to the area where too much dirt is accumulated and is located at the top of the aeration tank 3, the geomembrane 4 will be squeezed due to the excessive dirt, causing the geomembrane 4 to be too tightly in contact with the top of the aeration tank 3, so that when the ring plate 5 pulls the geomembrane 4, the geomembrane 4 cannot move and is over-stretched, causing the geomembrane 4 to be damaged. Therefore, when the geomembrane 4 moves, the slapping component is used to slap the dirt on the inner side of the geomembrane 4 to separate the dirt from the geomembrane 4, so that the subsequent geomembrane 4 will not be affected by too much dirt and the excessive squeezing of the geomembrane by the top of the aeration tank 3, thereby preventing the geomembrane 4 from being damaged.

[0026] like Figures 3 to 5 As shown, the flapping assembly includes: a moving block 15, a second spring 16, a mounting plate 17, a cylinder 18 and a first electromagnet 19; The top wall of the annular groove 14 is equidistantly provided with movable grooves, and the movable block 15 is slidably arranged in the corresponding movable groove. The movable block 15 is fixedly connected to the mounting plate 17, and a mounting opening is provided on the mounting plate 17. The cylinder 18 is rotatably installed in the mounting opening. The two ends of the second spring 16 are respectively fixedly connected to the inner wall of the movable groove and the movable block 15. The first electromagnet 19 is fixed on the inner wall of the annular groove 14 away from the cylinder 18. The mounting plate 17 is made of iron.

[0027] The cylinder 18 abuts against the outer side of the geomembrane 4 . The cylinder 18 is located below the top of the aeration tank 3 . When the cylinder 18 abuts against the geomembrane 4 , there is a gap between the moving block 15 and the inner wall of the moving groove away from the second spring 16 .

[0028] Start the first electromagnet 19 to intermittently power on and off, so that the first electromagnet 19 can intermittently have magnetism and lose its magnetism. When the first electromagnet 19 is magnetic, the mounting plate 17 is attracted to move with the cylinder 18 and the moving block 15 in the direction close to the first electromagnet 19, so that the second spring 16 is compressed to deform and generate a force. When the magnetism disappears, the compressed second spring 16 releases the force to quickly reset the moving block 15, the mounting plate 17 and the cylinder 18, so that the cylinder 18 hits the geomembrane 4, causing the geomembrane 4 to vibrate, thereby shaking off the dirt on its surface. The cylinder 18 is rotatably set, so that when it conflicts with the geomembrane 4, the friction between the cylinder 18 and the geomembrane 4 is small, which facilitates the movement of the geomembrane 4.

[0029] like Figure 3As shown, the top of the lifting plate 6 is symmetrically provided with an embedding groove, in which a second electromagnet 20 is fixedly installed, the body of the aeration pipe installation pipe 8 is made of iron, and the aeration pipe installation pipe 8 is adsorbed and fixed on the top of the lifting plate 6 by the second electromagnet 20, and an aeration head is provided on the top of the aeration pipe installation pipe 8, and a hose 23 is connected to the outside of the aeration pipe installation pipe 8.

[0030] The hose 23 is connected to an external fan so that airflow is introduced into the aeration tube installation pipe 8 through the hose 23, and the airflow is sprayed into the sewage through the aeration head for aeration. The second electromagnet 20 is energized and has magnetism, so that the aeration tube installation pipe 8 is adsorbed and fixed through the geomembrane 4, so that the aeration tube installation pipe 8 can be stably installed in the aeration tank 3. The second electromagnet 20 is powered off to make it lose its magnetism, so that when it is necessary to clean the inside of the geomembrane 4, the aeration tube installation pipe 8 can be separated from the geomembrane 4.

[0031] like Figure 1 As shown, the filtering and purification equipment includes: a processing pool 21 and a filter screen 22 , and the filter screen 22 is arranged inside the processing pool 21 .

[0032] A sewage pump 24 is fixedly installed on the top of the black film biogas tank 1 and the treatment tank 21. The output end and input end of the sewage pump 24 are connected to telescopic pipes, which extend into the black film biogas tank 1, the treatment tank 21 and the aeration tank 3.

[0033] Start the sewage pump 24 on the black film biogas tank 1 to make it work. The sewage pump 24 cooperates with the telescopic pipe to pump out the sewage in the black film biogas tank 1 and inject it into the aeration tank 3. Start the sewage pump 24 on the treatment tank 21 to make it cooperate with the telescopic pipe to pump out the sewage in the aeration tank 3 and inject it into the treatment tank 21. The sewage is filtered in the treatment tank 21 and remains in the treatment tank 21.

[0034] Working principle: When in use, sewage is introduced into the black film biogas tank 1 to decompose organic matter, and the treated sewage is introduced into the aeration tank 3 to combine with the activated sludge put into the aeration tank 3 to decompose the organic matter in the sewage into harmless substances such as carbon dioxide and water, thereby purifying the sewage. At the same time, aeration is performed through the aeration plate of the aeration pipe 8 to improve the reaction effect. The treated sewage is introduced into the filtering and purification equipment for filtering and purification, and finally discharged, thereby achieving the treatment of sewage so that it can be recycled for use; When the geomembrane 4 in the aeration tank 3 needs to be cleaned, the sewage in the aeration tank 3 is pumped out, the cylinder 7 is started to extend its cylinder rod to lift the lifting plate 6, thereby dragging the geomembrane 4 up, and at the same time, the motor 12 is started to make its output shaft rotate forward with the take-up drum 13, so that the winding rope 11 is pulled down, thereby pulling the slider 9 and the ring plate 5 down, and when the slider 9 is lowered, the first spring 10 is compressed to deform and generate a force, and the ring plate 5 pulls the end of the geomembrane 4 connected to it to descend, so that the geomembrane 4 is gradually wrapped around the outside of the aeration tank 3, and finally the lifting plate 6 is located at the top of the aeration tank 3, and the geomembrane 4 with the dirt inside it is located on the outside of the aeration tank 3, so that it is convenient to clean the dirt, and the second electric The magnet 20 is powered off, and the aeration pipe installation pipe 8 is removed, so that the geomembrane 4 can be better cleaned, and with the rise of the lifting plate 6, the harmful gas in the aeration tank 3 is discharged outward, so that when the aeration tank 3 is subsequently cleaned, there is no need to spend a lot of time waiting for the emission of harmful gases in the aeration tank 3 to disappear, thereby improving the cleaning efficiency. Through the above operation, when cleaning the geomembrane 4 in the aeration tank 3, it is not necessary to enter the aeration tank 3, and the geomembrane 4 can be cleaned, saving time and effort. During use, dirt will accumulate on the inside of the geomembrane 4. If too much dirt accumulates somewhere in the geomembrane 4, when the geomembrane 4 is pulled by the ring plate 5 to the area where too much dirt is accumulated at the top of the aeration tank 3, due to too much dirt, the geomembrane 4 is damaged. The geomembrane 4 is squeezed so that the contact between the geomembrane 4 and the top of the aeration tank 3 is too tight, so that when the ring plate 5 pulls the geomembrane 4, the geomembrane 4 cannot move and is over-stretched, so that the geomembrane 4 is broken. Therefore, when the geomembrane 4 moves, the first electromagnet 19 is started to intermittently power on and off, so that the first electromagnet 19 can intermittently have magnetism and lose its magnetism. When the first electromagnet 19 is magnetic, the mounting plate 17 is attracted to move with the cylinder 18 and the moving block 15 in the direction close to the first electromagnet 19, so that the second spring 16 is compressed to deform and generate a force. When the magnetism disappears, the compressed second spring 16 releases its force and carries the moving block 15, the mounting plate 17, the cylinder 18 and the moving block 15. The column 18 is quickly reset, so that the cylinder 18 hits the geomembrane 4, causing the geomembrane 4 to vibrate, thereby shaking off the dirt on its surface, separating the dirt from the geomembrane 4, and preventing the subsequent geomembrane 4 from being excessively squeezed by the top of the aeration tank 3, thereby preventing the geomembrane 4 from being damaged; after cleaning, the second electromagnet 20 is energized, the aeration pipe installation pipe 8 is reset to fix it with the second electromagnet 20, the motor 12 is started to reverse its output shaft, so that the take-up drum 13 is reversed to release the pull rope 11, and the first spring 10 releases the force to carry the slider 9 and the ring plate 5 up, shortens the cylinder 7 and resets it, realizes the reset of the lifting plate 6, and finally completes the reset of the geomembrane 4.

[0035] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
