Description

Technical Field

[0001] The present invention belongs to the technical field of sewage treatment, and in particular relates to wind and light integrated treatment equipment for decentralized domestic sewage. Background Art

[0002] In rural areas, due to the dispersed living patterns and relatively sparse population density, traditional centralized sewage treatment systems are difficult to adapt due to high construction costs and difficulties in laying pipelines; in view of this, decentralized sewage treatment technology, with its flexibility and adaptability, has become an effective way to solve rural sewage problems.

[0003] Decentralized sewage treatment equipment is widely used in rural areas. They usually have a high daily treatment capacity and can meet the sewage treatment needs of villages of different sizes. However, during the long-term operation of these equipment, due to the lack of regular maintenance and cleaning, coupled with the relative scarcity of electricity resources in rural areas, the energy consumption in the sewage treatment process is huge and the efficiency is not ideal; especially in key treatment links such as aeration, the power consumption is particularly significant. If grid-connected power is used for aeration treatment, this will significantly increase the operating cost; in addition, due to the various complex treatment components in the equipment, it is also very difficult to maintain, especially when the filler is used for a long time, there will be a lot of dirt or aging biofilm. If it is not effectively cleaned, the cost of equipment maintenance will become higher and higher, which will also cause the quality of the purified sewage to deteriorate.

[0004] Therefore, a sewage treatment device is proposed which is easy to realize automatic energy supply by using clean energy such as wind and light, and can effectively clean dirt, so as to facilitate equipment maintenance and reduce equipment maintenance costs. Summary of the invention

[0005] In response to the above problems, the present invention provides an integrated wind and light treatment device for decentralized domestic sewage, which is used to solve the problems of high power consumption of sewage treatment equipment in rural areas, difficulty in maintaining the equipment after long-term use, high maintenance cost, and easy impact on the quality of purified water.

[0006] To achieve the above object, the technical solution adopted by the present invention is:

[0007] Wind and light integrated treatment equipment for decentralized domestic sewage, comprising a tank body, wherein a plurality of chambers are arranged in the tank body, including a first treatment chamber and a second treatment chamber which are interconnected and arranged to treat sewage;

[0008] An aeration pipe for aerating the sewage is arranged in the first treatment chamber, the aeration pipe is connected to an air source assembly arranged on the top of the tank body, and the air source assembly is connected to a power supply device;

[0009] The second treatment chamber is provided with a plurality of groups of first fillers and second fillers that can be movably arranged up and down. The air sprayed from the air source assembly enters the second treatment chamber and can contact the first fillers and the second fillers to participate in the reaction to purify the sewage.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] By connecting to the power supply device, the air source component is powered. The power supply device uses wind energy and solar energy to generate electricity, which can reduce the use of grid-connected electricity, thereby reducing grid-connected electricity consumption and achieving self-sufficient electricity demand. The power supply device supplies power to the air source component, so that the air source component and the aeration pipe aerate the sewage in the first treatment chamber, so that aerobic bacteria can fully contact oxygen, thereby improving the effect of sewage treatment in the first treatment chamber; the air in the air source component is reintroduced into the first filler and the second filler, so that the bacteria on the filler can effectively reproduce and can fully treat the sewage, and by setting the second filler to an up and down movable state, the sewage can be partially stirred, which is conducive to the accelerated shedding of the aged biofilm of the bacteria on the first filler and the second filler, and the new biofilm will grow again, so it can play the role of self-maintenance during operation, making equipment maintenance easier, thereby maintaining the purification efficiency of the equipment.

[0012] As a further improvement of the above solution, a separation hood is fixedly arranged in the first treatment chamber, the separation hood covers the aeration pipe in the middle position, and a sludge collecting bucket for collecting sludge is arranged on the outside of the separation hood;

[0013] A stirring piece is also rotatably arranged in the separation cover, and a first wind cap is fixedly arranged on the top of the stirring piece to drive the stirring piece to rotate.

[0014] The technical effect of the above improvement is: by setting the first wind hood, the first wind hood and the stirring element can be synchronously driven to rotate when the wind blows, thereby stirring the water in the first treatment chamber to increase the oxygen content in the water. After aeration, the water and sludge are separated from each other, and the sludge will be deposited on the sludge collecting bucket on both sides to facilitate the separation of water and sludge.

[0015] As a further improvement of the above solution, a barrier cover fixed to the tank body is rotatably provided on the stirring member, the opening of the barrier cover faces downward and covers the top of the separation cover;

[0016] The stirring element is also provided with a driving assembly for driving the stirring element to rotate. One side of the barrier cover is connected to the driving assembly through a pipeline, and a control valve for switching on and off the controller is provided on the pipeline.

[0017] The technical effect of the above improvement is: the air source component fills air into the first treatment chamber for aeration, and the air precipitated from the water will gradually be collected on the barrier cover, and with the continuous aeration, more and more gas is collected on the barrier cover, which will increase the pressure on the barrier cover. Therefore, when the control valve on the pipeline between the drive component and the barrier cover is opened, the air on the barrier cover can be blown into the drive component, thereby further accelerating the rotation of the driving stirring element to achieve faster stirring of the sewage.

[0018] As a further improvement of the above solution, an air inlet pipe for taking air into the second processing chamber is further provided in the second processing chamber, an air outlet pipe for exhausting air to the outside is further provided on the water outlet side of the second processing chamber, and a second wind cap is provided on the top of the air outlet pipe;

[0019] The air inlet pipe and the air outlet pipe extend into the bottom of the second processing chamber, and a plurality of fine holes for gas inlet and outlet are arranged on the surface.

[0020] The technical effect of the above improvement is: through the set air outlet pipe, the air in the second processing chamber can be sucked when the wind blows and rotates, and the outside air will be sucked into the second processing chamber to participate in the reaction on the filler, thereby realizing unpowered water purification.

[0021] As a further improvement of the above solution, a partition is further provided in the second processing chamber, a water collecting tank that can be lifted up and down is movably provided in the partition, and the second filler is fixed on the lower side of the water collecting tank;

[0022] A plurality of compartments are arranged in the water collection tank, and a third filler is arranged in each compartment;

[0023] A plurality of siphon tubes corresponding to the positions of the second fillers are arranged on the inner wall of the water collecting tank. The siphon tubes are bent and extend downward to the bottom of the water collecting tank, and introduce the water in the water collecting tank to the second filler.

[0024] As a further improvement of the above scheme, a water diversion pipe assembly is provided between the first treatment chamber and the second treatment chamber to facilitate water to flow into the second treatment chamber, the water diversion pipe assembly includes a first water diversion pipe, a second water diversion pipe and a third water diversion pipe connected to each other through a tee, and the third water diversion pipe is located above the water collecting tank and introduces water into the water collecting tank, the water outlet end of the second water diversion pipe is close to the bottom of the second treatment chamber, and a throttling component is provided at the bottom end of the second water diversion pipe;

[0025] A second return spring is arranged between the partition and the water collecting tank to pull the water collecting tank upward and return to its original position.

[0026] The technical effect of the above improvement is: through the water diversion pipe assembly, the water flowing out of the first treatment chamber can enter the water collecting tank, and the water can be further purified through the third filler. When the water on the water collecting tank increases, the water collecting tank will move downward, thereby driving the second filler to move downward. In the process of continuous water supply, the water will be introduced into the second filler through the siphon effect of the siphon tube, thereby purifying the water quality on the second filler. After the water is continuously sucked away by the siphon tube, it will move upward under the pull of the second return spring, so that the second filler can move upward, realizing the control of the up and down movement of the second filler, thereby stirring the water flow; when the water in the second treatment chamber completely overflows the top of the water collecting tank, the water collecting tank and the second filler are at the uppermost position under the pull of the second return spring and will not move up and down.

[0027] As a further improvement of the above scheme, the throttling component includes a connecting pipe arranged at the end of the second water inlet pipe, the connecting pipe is connected to a water outlet with a gradually narrowing pipe mouth, a valve core is movably arranged in the connecting pipe and can close the inlet of the water outlet, and a first return spring is arranged between the valve core and the connecting pipe.

[0028] The technical effect of the above improvement is: the set valve core can pass through when the water pressure is relatively small and introduce water downward into the second processing chamber, and when the water pressure is relatively large, it will have a squeezing effect on the valve core, so that the downward flow path of the water is cut off, and most of the water flows out upward through the third water pipe.

[0029] As a further improvement of the above solution, the tank body is provided with an upwardly protruding tank mouth, a support plate is detachably provided on the tank mouth, a winding wheel is rotatably provided on the support plate, and a driving source is connected to the winding wheel;

[0030] A first pull line fixed to the water collecting tank is wound around the winding wheel;

[0031] A second pull wire fixed to the third filler is fixedly arranged on the support plate.

[0032] The technical effect of the above improvement is: through the arranged winding wheel, the water collection tank can be lifted upward, so that the second filler is separated from the first filler upward. At this time, the first filler and the second filler are no longer arranged in an interlaced manner, but a gap is generated between the first filler and the second filler, which can facilitate the discharge of dirt in the water.

[0033] As a further improvement of the above solution, the air outlet of the air source assembly is also connected to an air supply pipe, which is introduced into the bottom of the second processing chamber and passes through a plurality of first fillers;

[0034] The air supply pipe is provided with a plurality of overflow ports for introducing gas into the first filler, and the air supply pipe is also provided with a plurality of air outlet joints, and a section of hose is provided between the air outlet joints and the air supply pipe.

[0035] The technical effect of the above improvement is: through the set overflow port, the introduced air can enter the first filler, thereby increasing the contact area between the filler and the air, providing more oxygen, and thus improving the water purification effect. When the gas passes through the air outlet joint, due to the action of the hose, the air outlet joint will swing in different directions and blow out gas, so that the water flow in the first filler can also be stirred, so that the aged biofilm and other waste on the first filler can be facilitated to flow out.

[0036] As a further improvement of the above solution, the tank body further includes an anaerobic chamber and a storage chamber, the anaerobic chamber is connected to the first processing chamber through a water inlet pipe, and a one-way valve is provided on the water inlet pipe;

[0037] The storage chamber and the second processing chamber are communicated with each other through a pipeline;

[0038] The power supply device also includes a wind power generator and a solar panel arranged on the tank body. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] In order to enable those skilled in the art to better understand the technical solution, the present invention is described in detail below in conjunction with embodiments. The description in this section is only exemplary and explanatory and should not have any limiting effect on the scope of protection of the present invention.

[0048] like Figure 1-7 As shown, the specific scheme of this embodiment is: a wind and light integrated treatment device for decentralized domestic sewage, including a tank body 10, a plurality of chambers are arranged in the tank body 10, including a first treatment chamber 11 and a second treatment chamber 12 which are arranged in communication with each other and treat sewage; the tank body 10 also includes an anaerobic chamber 13 and a storage chamber 14, the anaerobic chamber 13 is connected to the first treatment chamber 11 through an inlet pipe 15, and a one-way valve and a cut-off valve are arranged on the inlet pipe 15, and the cut-off valve is closed when the oxygen content of aeration in the first treatment chamber 11 does not meet the requirement, so as to reduce the water supply to the first treatment chamber 11; the storage chamber 14 and the second treatment chamber 12 are connected to each other through a pipeline; the sewage to be treated enters from the anaerobic chamber 13, an anaerobic fermentation treatment is carried out in the anaerobic chamber 13, the treated water enters the first treatment chamber 11 for aerobic aeration, the aerated water enters the second treatment chamber 12 for treatment by fillers, and finally the water is discharged to the storage chamber 14 for storage;

[0049] An aeration pipe 1101 for aerating the sewage is arranged in the first treatment chamber 11, and the aeration pipe 1101 is connected with an air source assembly 1102 arranged on the top of the tank body 10. Specifically, the air source assembly 1102 includes an electric push rod that can reciprocate, and the output shaft end of the electric push rod is connected to a piston. Two pistons are arranged, which are located on both sides of the electric push rod. When the electric push rod reciprocates, one piston can take in air and the other can exhaust air. The air outlet end of the piston is connected to a three-way control valve, and one of the passages of the three-way control valve is connected to the aeration pipe 1101 to aerate the sewage; the air source assembly 1102 is connected to a power supply device, and the power supply device includes a wind turbine 16 and a solar panel 17 arranged on the tank body 10. Therefore, by converting wind energy and solar energy into the electric energy required for equipment processing, the consumption of grid-connected circuit electric energy can be reduced, self-sufficiency can be achieved, and equipment energy consumption can be reduced.

[0050] The second processing chamber 12 is provided with a plurality of groups of first fillers 1201 and second fillers 1202 that can be movably arranged up and down. Figure 1 As shown, the first filler 1201 and the second filler 1202 are made into a cubic plate structure by using a grid frame, and the first filler 1201 and the second filler 1202 are arranged alternately, and the height of the first filler 1201 located on the side close to the first processing chamber 11 is higher than the height of other first fillers 1201, so that it can be ensured that after the air can enter the second processing chamber 12, it must pass through the filler before it can be discharged, and the air ejected from the air source component 1102 enters the second processing chamber 12 and can contact with the first filler 1201 and the second filler 1202, and participate in the reaction To purify sewage, specifically, the air entering the second treatment chamber 12 provides oxygen to the microorganisms on the first filler 1201 and the second filler 1202, so that the microorganisms can purify the water quality during aerobic respiration. By arranging the second filler 1202 to be movable up and down, the water can be stirred during sewage treatment, so that the dirt or aged biofilm on the first filler 1201 and the second filler 1202 can be accelerated to fall off, thereby achieving the effect of self-cleaning and self-maintenance, making the entire equipment more convenient and easy during manual maintenance.

[0051] like Figure 1 As shown, as a preferred embodiment of the above embodiment, a separation hood 1103 is fixedly provided in the first processing chamber 11. The separation hood 1103 is in a cone shape with a small upper end and a large lower end. The separation hood 1103 covers the aeration pipe 1101 in the middle position. A mud collecting bucket 1108 for collecting sludge is provided on the outside of the separation hood 1103. The mud collecting bucket 1108 is specifically a guide vane provided on the outside of the separation hood 1103. The guide vane is provided in a ring shape. After the settled sludge is collected on the mud collecting bucket 1108, it can be sucked outward through a pipeline provided on the mud collecting bucket 1108.

[0052] A dissolved oxygen detector 1109 for detecting the aeration oxygen content in the first treatment chamber 11 is fixedly arranged on the outer wall of the separation cover 1103. This is mainly because the electric energy provided by the wind turbine 16 and the solar panel 17 in rural areas may be unstable, and the aeration is unstable. Therefore, it is necessary to detect the aeration oxygen content of the sewage through the dissolved oxygen detector 1109. When the oxygen content is reduced, a signal will be transmitted to the cut-off valve on the water inlet pipe 15 to reduce the water supply to the first treatment chamber 11. Generally, the cut-off valve is normally closed. When the dissolved oxygen detector 1109 detects that the oxygen content is high, the cut-off valve will be opened to supply water.

[0053] A stirring member 1105 is also rotatably arranged in the separation cover 1103, and a first wind hood 1107 is fixedly arranged on the top of the stirring member 1105 to drive it to rotate. Therefore, when the wind blows the first wind hood 1107 to rotate, the stirring member 1105 can be driven to rotate, so that the stirring member 1105 stirs the sewage to increase the oxygen content of the sewage.

[0054] As a preferred embodiment of the above embodiment, a barrier cover 1104 fixed to the tank body 10 is rotatably provided on the stirring member 1105. The barrier cover 1104 is specifically a conical structure. The opening of the barrier cover 1104 faces downward and covers the top of the separation cover 1103. Therefore, the gas charged by aeration will be collected upward in the barrier cover 1104, and in the continuous aeration process, the air will be continuously collected in the barrier cover 1104.

[0055] The stirring member 1105 is also provided with a driving assembly 1106 for driving the stirring member 1105 to rotate. The driving assembly 1106 is arranged on the outside of the tank body 10. Specifically, a wind wheel (not shown in the accompanying drawings) fixed to the rotating shaft of the stirring member 1105 is arranged inside the driving assembly 1106. One side of the barrier cover 1104 is connected to the driving assembly 1106 through a pipeline. The pipeline is provided with a control valve for controlling the on-off of the driving assembly 1106. The control valve is specifically a pressure control valve. That is, when the air collected in the barrier cover 1104 reaches a certain amount, the pressure increases, thereby opening the control valve, and the air in the barrier cover 1104 is ejected outward, and ejected through the pipeline to the wind wheel of the driving assembly 1106, thereby accelerating the rotation of the stirring member 1105.

[0056] like Figure 1 , 45, as a preferred embodiment of the above embodiment, an air inlet pipe 1203 for taking air into the second processing chamber 12 is further provided in the second processing chamber 12, and an air outlet pipe 1204 for exhausting air to the outside is also provided on the water outlet side of the second processing chamber 12, and a second wind cap is provided on the top of the air outlet pipe 1204. When the wind blows, the second wind cap can drive the wind inside the air outlet pipe 1204 to be drawn outward, so that the outside air flows into the second processing chamber 12 through the air inlet pipe 1203;

[0057] The air inlet pipe 1203 and the air outlet pipe 1204 extend into the bottom of the second treatment chamber 12, and a number of fine holes are arranged on the surface for facilitating the entry and exit of gas. Through the arranged air inlet pipe 1203 and the air outlet pipe 1204, air can be introduced into the second treatment chamber 12 without power, so that the first filler 1201 and the second filler 1202 can purify the sewage after contacting with the air.

[0058] As a preferred embodiment of the above, a partition 1205 is further provided in the second processing chamber 12, and the space isolated by the partition 1205 is connected to the cavity near the second processing chamber 12. A water collecting tank 1206 that can be lifted up and down is movably provided in the partition 1205, and the second filler 1202 is fixed on the lower side of the water collecting tank 1206; and a plurality of compartments are provided in the water collecting tank 1206, and a third filler 1207 is arranged in each compartment, such as Figure 4 , three compartments are specifically arranged on the water collecting tank 1206, and the tops of the third fillers 1207 arranged in each compartment are fixed together by connecting rods, and the air entering the second processing chamber 12 can enter the space isolated by the partition 1205 and pass through the third fillers 1207 to participate in the reaction;

[0059] A water pipe assembly 1208 is provided between the first treatment chamber 11 and the second treatment chamber 12 to facilitate water to flow into the second treatment chamber 12. The water pipe assembly 1208 includes a first water pipe 12081, a second water pipe 12082 and a third water pipe 12083 which are connected to each other through a tee. Figure 4 , and the third water diversion pipe 12083 is located above the water collection tank 1206 and introduces water into the water collection tank 1206. When the third water diversion pipe 12083 introduces sewage into the water collection tank 1206, the water on the water collection tank 1206 increases, the weight increases, and it will sink downward, thereby synchronously driving the second filler 1202 to move downward. A second return spring 1209 is provided between the partition plate 1205 and the water collection tank 1206 to pull the water collection tank 1206 to move upward and return to its original position;

[0060] A plurality of siphon tubes 1219 are provided on the inner wall of the water collecting tank 1206 corresponding to the positions of the second fillers 1202. Figure 5The siphon tube 1219 is bent and extends downward to the bottom of the water collection tank 1206, and introduces the water in the water collection tank 1206 to the second filler 1202. Therefore, when the water on the water collection tank 1206 overflows, the siphon tube 1219 will draw the water on the water collection tank 1206 downward by siphon action, and the drawn water is introduced to the second filler 1202 for purification. After the water on the water collection tank 1206 is drawn away, the weight on the water collection tank 1206 is reduced, and the water collection tank 1206 can be pulled by the second return spring 1209. 6 and the second filler 1202 rebound upward and reset, so that the second filler 1202 can be driven to move up and down when the water collecting tank 1206 is driven to move up and down, thereby reducing the accumulation of dirt and some detached biofilms on the second filler 1202, keeping the filler clean, and providing a good water quality treatment effect. When the water in the second treatment chamber 12 submerges the water collecting tank 1206, the water collecting tank 1206 will lose the function of moving up and down, which is only applicable to the situation where the liquid level in the second treatment chamber 12 is lower than the bottom surface of the water collecting tank 1206.

[0061] like Figure 1 , 6 As shown in Figures 7 and 8, as a preferred embodiment of the above embodiment, the water outlet end of the second water diversion pipe 12082 is close to the bottom of the second processing chamber 12, and a throttling component is provided at the bottom of the second water diversion pipe 12082; the throttling component includes a connecting pipe 12084 provided at the end of the second water diversion pipe 12082, and the connecting pipe 12084 is connected with a water outlet end 12085 with a gradually narrowing pipe mouth, and a valve core 12086 is movably provided in the connecting pipe 12084 and can close the inlet of the water outlet end 12085, and a first return spring 12087 is provided between the valve core 12086 and the connecting pipe 12084, as shown in Figures 7 and 8. Figure 6 Specifically, when the water pressure flowing out of the second water pipe 12082 is high, the valve core 12086 can be squeezed to close the water outlet 12085, and the water flowing downward is reduced. Most of the water flows out from the third water pipe 12083, and the pressure of the water flowing out of the first treatment chamber 11 is mainly due to the fact that the air filled into the first treatment chamber 11 during aeration increases the pressure, while the first water pipe 12081 and the third water pipe 12083 have small diameters and cannot quickly introduce water into the second treatment chamber 12, thereby increasing the water pressure in the first treatment chamber 11.

[0062] like Figure 4As shown, as a preferred embodiment of the above embodiment, the tank body 10 is provided with an upwardly protruding tank mouth 1210, and a support plate 1211 is detachably provided on the tank mouth 1210, and a winding wheel 1212 is rotatably provided on the support plate 1211, and the winding wheel 1212 is connected to a driving source, and the specific driving source is a set motor, and the motor is electrically connected to the power supply device; a first pull wire 1213 fixed to the water collecting tank 1206 is wound around the winding wheel 1212, so that when the motor is started, the winding wheel 1212 can be driven to rotate, thereby winding the winding wheel 1212, so that the water collecting tank 1206 can move upward as a whole, and after the water collecting tank 1206 moves upward as a whole, the second filler 1202 and the first filler 1201 can be separated, refer to the attached Figure 7 , so that the dirt and the detached biofilm on the first filler 1201 and the second filler 1202 can be discharged to the outside, reducing the accumulation on the filler, and because the aeration pipe 1101 close to the first treatment chamber 11 is high, it can be ensured that the sewage can still pass through the filler, avoiding being discharged directly to the outside without being treated;

[0063] A second pull wire 1214 fixed to the third filler 1207 is fixedly provided on the support plate 1211 . The second pull wire 1214 can lift the third filler 1207 upward when the water collecting tank 1206 moves downward.

[0064] like Figure 1 , 3 As shown, as a preferred embodiment of the above embodiment, the air outlet of the air source component 1102 is also connected to an air supply pipe 1215, which is introduced into the bottom of the second processing chamber 12 and passes through a plurality of first fillers 1201; the air supply pipe 1215 is provided with a plurality of overflow ports 1216 for introducing gas into the first fillers 1201, and the air supply pipe 1215 is also provided with a plurality of air outlet connectors 1217, and a section of hose 1218 is provided between the air outlet connector 1217 and the air supply pipe 1215. Specifically, the three-send control valve connected to the piston of the air source component 1102 is connected to the air supply pipe 1215, and when air is supplied through the air supply pipe 1215, the air is introduced The air can enter the first filler 1201 through the overflow port 1216 and fully contact the filler to improve the purification effect of the filler. When the air is ejected through the air outlet joint 1217, the air outlet joint 1217 and the hose 1218 can be swung in different directions due to the reaction force. Therefore, when the air is ejected, the water flow is stirred to allow the dirt and the detached biofilm on the first filler 1201 and the second filler 1202 to be detached and discharged to the outside. Therefore, the first filler 1201 and the second filler 1202 can be self-cleaned through this structure to achieve the effect of self-maintenance during sewage treatment.

[0065] The specific working principle of the present invention is as follows: first, rural domestic sewage is introduced into the anaerobic chamber 13 for anaerobic fermentation, and then the sewage enters the first treatment chamber 11. In the first treatment chamber 11, the sewage in the second treatment chamber 12 can be aerated by continuous air supply from the air source component 1102;

[0066] During aeration, the three-way control valve connected to the piston of the air source component 1102 introduces air into the aeration pipe 1101 and contacts the sewage in the second treatment chamber 12. Under the action of wind, the first wind cap 1107 can be blown to rotate, so that the stirring member 1105 stirs the sewage to increase the oxygen content of the sewage. In the continuous aeration process, the aerated air is collected in the barrier cover 1104, so that the pressure in the first treatment chamber 11 increases. When the pressure reaches the opening pressure of the control valve on the pipeline connecting the barrier cover 1104 and the driving component 1106, the control valve opens, thereby introducing the air in the barrier cover 1104 into the driving component 1106, thereby accelerating the rotation of the stirring member 1105.

[0067] The water after aeration in the first treatment chamber 11 enters the second treatment chamber 12 through the water guide pipe assembly 1208. When the water pressure is high, it can enter the third water guide pipe 12083, so that the water is sprayed out from above the third filler 1207, so that the third filler 1207 can also contact with the water, so as to treat the water quality. When the liquid level in the second treatment chamber 12 is lower than the bottom surface of the water collecting tank 1206, the increase of water flowing to the water collecting tank 1206 will increase the weight of the water collecting tank 1206, thereby The water collecting tank 1206 moves downward. After the water on the water collecting tank 1206 is siphoned out through the siphon tube 1219, it moves upward and resets under the pull of the second reset spring 1209. The second filler 1202 can be driven to move up and down to stir the water flow, thereby cleaning the surface of the second filler 1202 and improving the treatment effect of the second filler 1202. When the water pressure in the first treatment chamber 11 is relatively low, the sewage overflows into the second treatment chamber 12 through the second water diversion pipe 12082.

[0068] In order to further discharge the dirt and the detached biofilm on the first filler 1201 and the second filler 1202, the three-way control valve connected to the piston on the air source assembly 1102 is connected to the air supply pipe 1215 to inject air into the second processing chamber 12. Part of the air contacts the first filler 1201 through the overflow port 1216, and part of the air is ejected outward through the air outlet connector 1217 and the hose 1218, so that the water flow in the second processing chamber 12 is stirred, so that the dirt and the detached biofilm are separated from the first filler 1201 and the second filler 1202, and the reel 1201 is rotated. When the motor connected to 1212 is powered on, the reel 1212 can rotate to wind the first pull line 1213, thereby lifting the water collection tank 1206 and the second filler 1202 upward, so that a channel flows out between the first filler 1201 and the second filler 1202, and the dirt and the detached biofilm on the first filler 1201 and the second filler 1202 can be discharged outward through the channel, playing a self-cleaning role. After the cleaning is completed, the reel 1212 rotates in the opposite direction to lower the water collection tank 1206 and the second filler 1202, and the first filler 1201 and the second filler 1202 continue to be arranged in a staggered manner;

[0069] Finally, the treated water flows into the storage chamber 14 to be stored for use.
