Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, and in particular to a biofilm sewage treatment machine. Background Art

[0002] Biofilm sewage treatment machine is a highly efficient wastewater treatment technology that uses microbial communities (biofilms) attached to the surface of solid media (such as membrane fibers, fillers) to purify sewage.

[0003] When residents of a community use a biofilm sewage treatment machine, since one biofilm sewage treatment machine is usually used by multiple households or even multiple buildings, the amount of wastewater flowing into the biofilm sewage treatment machine will increase sharply during the peak period of residents' water use, which increases the filtration pressure of the membrane filaments in the biofilm sewage treatment machine on the wastewater. At this time, the membrane filaments are usually changed to a wavy shape to increase the contact area between the membrane filaments and the wastewater, so as to improve the filtration effect of the membrane filaments on the wastewater. However, the closer the membrane filaments are to the aeration port, the more biological communities are distributed, resulting in uneven distribution of biological communities on the membrane filaments, and the depressions of the wavy membrane filaments are easy to adhere to filtered impurities, making it difficult for the biological communities to adhere to the depressions of the wavy membrane filaments, making the distribution of biological communities on the membrane filaments more uneven, affecting the filtration capacity of the membrane filaments for wastewater.

[0041] The blowing assembly includes a first high-pressure air pump 301, a first ventilation pipe 302, a second ventilation pipe 303 and a second nozzle 304; the first high-pressure air pump 301 is fixedly connected to the upper rear side of the box body 2; the output end of the first high-pressure air pump 301 is connected to a plurality of first ventilation pipes 302; each first ventilation pipe 302 passes through the adjacent second connecting pipe 203; a second ventilation pipe 303 is fixedly connected to the inner side of each second connecting pipe 203; one end of each first ventilation pipe 302 is connected to the adjacent second ventilation pipe 303; each second ventilation pipe 303 is connected to a plurality of left-right symmetrical second nozzles 304.

[0042] The cleaning assembly includes a second high-pressure air pump 401, a first air pipe 402, a second air pipe 403, a connecting rod 404 and an extrusion rod 405; two connecting rods 404 are fixedly connected in the box body 2; each connecting rod 404 is rotatably connected to a plurality of extrusion rods 405 through a torsion spring, and each extrusion rod 405 corresponds one-to-one to an adjacent semicircular groove 5001; a second high-pressure air pump 401 is fixedly connected to the front left side of the box body 2; the output end of the second high-pressure air pump 401 is connected to the first air pipe 402; the first air pipe 402 is fixedly connected to the box body 2; a plurality of second air pipes 403 are connected to the rear side of the first air pipe 402; each second air pipe 403 is located above an adjacent extrusion rod 405, and each second air pipe 403 corresponds one-to-one to an adjacent second through groove 4002.

[0043] Before starting work, the water inlet pipe 101 is connected to the wastewater pipe, and the wastewater enters the box body 2 through the water inlet pipe 101. It is worth noting that since a sewage treatment machine is usually used by multiple households, the sewage entering the box body 2 is usually continuous. Then, when the wastewater level in the box body 2 is higher than the membrane wire group 3, the electric slider 206 is controlled to slide upward along the slide rail 205, thereby driving the second connecting pipe 203, the first nozzle 204 and the fixing frame 207 to move upward, thereby driving the collection bin 4, the first guide plate 5 and the second ventilation pipe 303 to move upward, and at the same time, the aerator 2 is controlled to move upward. 01 Air is pumped into the first connecting pipe 202, so that the air enters the second connecting pipe 203 along the first connecting pipe 202, and then is sprayed out from the first nozzle 204, so as to aerate the inside of the box 2 and increase the oxygen content in the water. At this time, under the filtration of the membrane fiber group 3, the impurities in the wastewater will adhere to the outside of the membrane fiber group 3, and the water filtered by the membrane fiber group 3 will move upward to the clean water pipe 104 under the action of the self-priming pump on the clean water tank 105 (hereinafter referred to as "the water flow filtered by the membrane fiber group 3" is called the purified water flow) and then enters the clean water tank 105 along the clean water pipe 104 to realize the collection of the purified water flow.

[0044] Subsequently, since the activity and species distribution of the biological community on the biofilm are directly related to the efficiency of organic matter degradation and nutrient element removal, if there is too much biomass in some areas and insufficient biomass in other areas, it will lead to different processing capabilities of the entire system and affect the effluent water quality. Therefore, the first nozzle 204 is driven by the electric slider 206 to move upward, so that the position of the first nozzle 204 in the wastewater is constantly changing, so that each position of the membrane wire group 3 is closer to the position of the first nozzle 204, so that the gas distribution position of the first nozzle 204 in the water will become more uniform, avoiding the first nozzle 204 position unchanged, resulting in membrane The closer the membrane wire group 3 is to the first nozzle 204, the more biological communities are distributed thereon because the oxygen content is significantly higher than other positions, while the oxygen content in the water at locations farther away from the first nozzle 204 is even lower, resulting in uneven distribution of biological communities adhered to the membrane wire group 3, affecting the filtration of wastewater by the membrane wire group 3. The above technical effect is different from the fixed aeration operation in the prior art, and can effectively avoid the above problems. Subsequently, the membrane wire group 3 is simultaneously arranged in a wavy shape, which is different from the horizontal setting in the prior art, so that the contact area between the membrane wire group 3 and the wastewater will be increased, thereby improving the filtration effect of the membrane wire group 3 on the wastewater.

[0045] Furthermore, when the collecting bin 4 and the first guide plate 5 are moving upward, the collecting bin 4 and the first guide plate 5 will squeeze the protruding portion 3002, so that the recessed portion 3001 and the protruding portion 3002 are deformed under the squeezing of the collecting bin 4 and the first guide plate 5, so that the recessed portion 3001 is deformed, so that the impurities in the recessed portion 3001 are more easily separated under the deformation of the recessed portion 3001. At the same time, the first high-pressure air pump 301 is controlled to pump air, so that the airflow enters the second air pipe 303 along the first air pipe 302, and then is ejected from the second nozzle 304, so that the airflow blows toward the recessed portion 3001 and the protruding portion 30 02, thereby blowing the airflow toward the recessed portion 3001 to blow off the impurities adhering to the recessed portion 3001, thereby cleaning the impurities in the recessed portion 3001, and avoiding the accumulation of impurities in the recessed portion 3001, which makes it difficult to clean the impurities in the recessed portion 3001, resulting in a reduction in the contact area between the membrane wire group 3 and the wastewater, and affecting the distribution of the biological community and the filtering effect of the membrane wire group 3. At the same time, in the process of squeezing the membrane wire group 3 by the collecting bin 4 and the first guide plate 5, the position between two adjacent membrane wires is squeezed by the guide sheet 6, and the two adjacent membrane wires are stretched apart, so that the distance between the two adjacent membrane wires is increased, thereby making the distance between the two adjacent membrane wires adhering to the membrane wire group 3 smaller. The impurities between the two membrane threads are broken and separated. At this time, since the pressure of the wastewater on the first guide plate 5 will not compress the elastic member 208 during the upward movement of the collecting chamber 4 and the first guide plate 5, the first guide plate 5 remains in its original state, and the collecting chamber 4 and the first guide plate 5 will squeeze the wastewater during the upward movement, so that the wastewater flows around the collecting chamber 4 and the first guide plate 5, so that the flowing wastewater flows along the guide sheet 6 to the position between the two adjacent membrane threads, so as to flush the two adjacent membrane threads, so that the impurities adhered to the two adjacent membrane threads fall off the membrane threads under the flushing of the wastewater, so as to achieve the flushing of the two adjacent membrane threads. Impurities adhered between the membrane threads are cleaned to prevent impurities from adhering in large quantities between two adjacent membrane threads, causing the membrane thread group 3 to be covered by impurities, affecting the filtering effect of the membrane thread group 3 on the wastewater, and covering the collecting bin 4 by the first guide plate 5 to prevent the collecting bin 4 from not being covered by the first guide plate 5, causing impurities in the wastewater to enter the collecting bin 4 when they are settled, so that in the process of the collecting bin 4 moving upward, the impurities settled in the collecting bin 4 move with the upward movement of the collecting bin 4, causing the impurities in the collecting bin 4 to flow out of the collecting bin 4 during the upward movement, and re-adhere to the membrane thread group 3, affecting the filtering effect of the membrane thread group 3 on the wastewater.

[0046] Then, when the collecting bin 4 and the first guide plate 5 move upward and are about to approach the wastewater surface, the squeezing rod 405 will gradually embed into the semicircular groove 5001, so that the squeezing rod 405 gradually squeezes the first guide plate 5, compressing the elastic member 208. In the initial state, the force of the torsion spring between the squeezing rod 405 and the connecting rod 404 is greater than the force of the elastic member 208, so that the first guide plate 5 is deformed and bends downward, thereby exposing the inside of the collecting bin 4, so that the impurities floating on the wastewater surface are removed during the collection bin 4 continues to move upward. It is possible to enter the collecting bin 4, and then remove the impurities floating on the wastewater surface through the collecting bin 4, thereby cleaning the impurities floating on the wastewater surface, and preventing the impurities on the wastewater surface from always floating on the wastewater surface, adhering to the inner wall of the box body 2 after the liquid level is lowered, being difficult to clean, rotting and stinking, corroding the box body 2, and affecting the service life of the box body 2. Subsequently, when the collecting bin 4 and the first guide plate 5 continue to move upward, the first guide plate 5 gradually separates from the extrusion rod 405, and the torsion spring between the extrusion rod 405 and the connecting rod 404 gradually returns to its original state. , so that the squeezing rod 405 gradually returns to its original state; when the second through slot 4002 on the collecting bin 4 moves upward to a position corresponding to the second air pipe 403, the second high-pressure air pump 401 is controlled to deliver the airflow to the first air pipe 402, so that the airflow is ejected from the second air pipe 403, so that the airflow ejected from the second air pipe 403 passes through the second through slot 4002 and enters the collecting bin 4, and blows the impurities collected in the collecting bin 4 to prevent the impurities from adhering to the collecting bin 4, so that the impurities move backward and then flow out from the rectangular slot 4001. Subsequently, the impurities flowing out of the rectangular groove 4001 will fall downward onto the second guide plate 106, then pass through the first through groove 2001 along the second guide plate 106, and finally fall downward into the miscellaneous material box 107, thereby realizing the cleaning of the impurities in the collecting bin 4 and avoiding the impurities in the collecting bin 4 always existing in the collecting bin 4, resulting in the impurities in the collecting bin 4 flowing out from the rectangular groove 4001 and the second through groove 4002 into the wastewater after the collecting bin 4 moves downward, and floating again on the surface of the wastewater, making the cleaning of the impurities on the surface of the wastewater by the collecting bin 4 ineffective.

[0047] Subsequently, the electric slider 206 is controlled to drive the second connecting tube 203, the collecting bin 4 and the first guide plate 5 to move downward, so that the collecting bin 4 squeezes the squeezing rod 405. Based on the view from left to right, the torsion spring on the squeezing rod 405 is compressed, and the squeezing rod 405 rotates counterclockwise, so that the collecting bin 4 and the first guide plate 5 continue to move downward after passing the squeezing rod 405, and continue to squeeze the protrusion 3002 during the downward movement, and clean the impurities on the protrusion 3002, thereby achieving repeated cleaning of impurities adhered to the protrusion 3002. Subsequently, after the collecting bin 4 and the first guide plate 5 move downward to the initial position, the electric slider 206 is repeatedly driven to drive the collecting bin 4 and the first guide plate 5 to move up and down until the impurities on the membrane filament group 3 and the impurities floating on the wastewater surface are cleaned.

[0048] During the wastewater filtration process, the electric valve on the sewage pipe 102 is opened, and the pump in the sewage tank 103 is turned on, so that the wastewater at the bottom of the box 2 and the impurities settled at the bottom of the box 2 enter the sewage tank 103 along the sewage pipe 102, so as to collect the sewage and impurities, avoid excessive accumulation of impurities at the bottom of the box 2, which causes the impurities at the bottom of the box 2 to accumulate upward and adhere to the membrane fiber group 3, affecting the filtration of the wastewater by the membrane fiber group 3, and at the same time, the impurities at the bottom of the box 2 can be cleaned, reducing the difficulty of manual work.

[0049] Example 2

[0050] On the basis of Example 1, Figure 8-Figure 11 As shown, each collecting bin 4 is arranged to be tilted backward; each first guide plate 5 is arranged to be tilted backward; in the process of the collecting bin 4 and the first guide plate 5 squeezing the protrusion 3002, the protrusion 3002 is deformed one after another, thereby causing the recessed portion 3001 to be deformed one after another, so that the two adjacent membrane filaments are dislocated in the process of deformation, thereby kneading the impurities between the two adjacent membrane filament groups 3, avoiding the impurities between the two membrane filaments from adhering too firmly, resulting in the above-mentioned impurities being difficult to break and separate when the membrane filaments are deformed, affecting the cleaning of the impurities adhering between the two adjacent membrane filaments.

[0051] Each first guide plate 5 is configured as an arc-shaped plate with a convex middle portion upward; when the collecting bin 4 and the first guide plate 5 move upward, squeezing the wastewater and causing the wastewater to move around the collecting bin 4 and the first guide plate 5, the first guide plate 5 guides the wastewater to move to the left and right sides of the first guide plate 5, thereby increasing the flow rate between two adjacent membrane wire groups 3, thereby improving the cleaning effect of impurities adhering to the two membrane wire groups 3.
