DETAILED DESCRIPTION

[0041] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the application.

[0042] The application provides a sewage efficient biological degradation device as shown in the figure, which comprises a treatment tank 1, a water inlet assembly 2, a biological adsorption assembly 3 and a biological treatment agent feeding assembly 4. Figures 1 to 14 The biological adsorption assembly 3 is provided with a plurality of biological adsorption assemblies 3, and the plurality of biological adsorption assemblies 3 are arranged on the outer side of the treatment tank 1 in a surrounding manner. The water inlet assembly 2, the biological treatment agent feeding assembly 4 and the treatment tank 1 are sequentially arranged from top to bottom.

[0043] The processing tank 1 comprises a fixed plate 101, upper and lower tank bodies 102 and 103 are respectively fixedly arranged on the middle of the two sides of the fixed plate 101, and a plurality of supporting legs 104 are arranged around the bottom end of the outer side wall of the lower tank body 103.

[0044] Specifically, a plurality of drain pipes 106 are arranged around the middle of the outer side wall of the lower tank body 103, a flow valve is connected in the drain pipe 106, the setting of the flow valve can control the drainage time of the sewage, the drain pipe 106 is arranged in an "L" shape, a fixed seat 107 is fixedly arranged at the middle of the bottom end of the lower tank body 103, the drain pipe 106 can discharge the sewage higher than the middle of the lower tank body 103, which can ensure the continuous treatment of the device to the sewage and avoid the influence of the fast discharge of the sewage on the play of the biological treatment agent.

[0045] In addition, a stirring motor 108 is fixedly arranged at the middle of the lower surface of the fixed seat 107, an output shaft of the stirring motor 108 is fixedly arranged with a stirring rod 109, and the stirring rod 109 is arranged in the interior of the lower tank body 103. The stirring rod 109 is arranged in the interior of the lower tank body 103, and the stirring rod 109 comprises a connecting shaft 1091 and a rotating rod 1092, wherein the connecting shaft 1091 is rotatably connected with the rotating rod 1092, and a plurality of stirring blades 110 are connected on the connecting shaft 1091 and the rotating rod 1092. The stirring blades 110 connected on the connecting shaft 1091 can rotate relative to the connecting shaft 1091. In this scheme, the rotation angle between the connecting shaft 1091 and the stirring blades 110 is 0°-90°. The stirring blades 110 connected on the rotating rod 1092 are provided with a storage hole 1101, and the storage hole 1101 does not penetrate the stirring blades 110. A pressure sensor is connected in the storage hole 1101. On the premise that the rotation rate of the stirring blades 110 on the rotating rod 1092 does not change, as the amount of the precipitate increases, the pressure value of the pressure sensor in the storage hole 1101 increases. The stirring motor 108 can drive the stirring rod 109 and the stirring blades 110 to rotate, so as to improve the mixing effect of the sewage and the biological treatment agent.

[0046] It should be noted that, by using the storage hole 1101 arranged on the stirring blade 110, when the sewage and the biological treatment agent are mixed, part of the sewage and the biological treatment agent can be mixed under the action of the storage hole 1101 through the rotation of the storage hole 1101. After sufficient mixing, the precipitate can be placed in the storage hole 1101 through the rotation of the stirring blade 110, and the content of the precipitate can be identified by the pressure received by the precipitate in the storage hole 1101 during the rotation process, so as to avoid the influence of too much precipitate in the sewage on the treatment efficiency of the sewage.

[0047] At the beginning of rotation, the connecting shaft 1091 and the rotating rod 1092 rotate synchronously, and at this time, the stirring blades 110 on the stirring rod 109 are at the same rotation angle, so that the stirring blades 110 drive the sewage and the biological treatment agent to be fully mixed, and as the sewage treatment content increases, the sediment content treated by the biological treatment agent increases, thereby meeting the liquid in the upper part of the discharge requirement, and as the sediment content increases, the rotation speed of the connecting shaft 1091 gradually decreases, and the stirring blades 110 on the connecting shaft 1091 are angularly rotated, so that the stirring force of the stirring blades 110 on the connecting shaft 1091 on the sewage decreases, so that the upper layer of sewage tends to be stable, and the sediment in the lower layer is blocked by the stirring blades 110 on the connecting shaft 1091, facilitating the output of the sewage.

[0048] More specifically, the bottom end of the lower tank body 103 is provided with a residue discharge port, wherein the residue discharge port is affected by the pressure of the pressure sensor on the storage hole 1101, that is, when the pressure value of the pressure sensor of the storage hole 1101 meets the set value, at this time, the flow valve on the drain pipe 106 is opened, and the upper layer of sewage is discharged, when there is no sewage flowing out of the drain pipe 106, at this time, the residue discharge port is opened, and the sediment and residual sewage are discharged and treated, in addition, when the drain pipe 106 discharges the upper layer of sewage, the stirring blades 110 on the rotating rod 1092 are still in a rotating state, ensuring that the organic matter in the sewage is fully reacted and combined with the biological treatment agent to meet the sewage discharge standard, and the residue discharge port is used to clean the sewage treatment sediment and residual sewage in the lower tank body 103.

[0049] The water inlet assembly 2 comprises a water inlet cover 201 arranged above the upper tank body 102.

[0050] Specifically, the outer side wall of the water inlet cover 201 is surrounded by a plurality of water guide pipes 202, and the bottom end of the water guide pipe 202 is penetratingly arranged on the upper surface of the fixed plate 101. The upper surface of the water inlet cover 201 is penetratingly provided with a water inlet pipe 203, and the inside of the water inlet pipe 203 is provided with an electromagnetic valve.

[0051] Specifically, during the flow of the sewage, a plurality of electromagnetic valves can be opened and closed alternately to ensure that the sewage can be circulated into a plurality of treatment cylinders 302. The intermittent delivery of the sewage in each treatment cylinder 302 can prolong the residence time of the sewage in the biological adsorption assembly 3 while ensuring the continuous delivery of the sewage.

[0054] More specifically, a plurality of bio-adsorption membranes 307 in a semicircular structure are fixedly arranged in the inside of the spherical cover 304, and the plurality of bio-adsorption membranes 307 are arranged in a circular array, the semicircular structure enables the spherical cover 304 to be provided with a plurality of bio-adsorption membranes 307, thereby improving the adsorption and treatment effect of the bio-adsorption assembly 3 on the sewage.

[0055] Furthermore, both ends of the fixed cylinder 301 are provided with a connecting seat 308, a plurality of connecting rods 309 are arranged around the outer wall of the connecting seat 308, one end of the connecting rod 309 is fixedly arranged on the inner wall of the fixed cylinder 301, a screw hole 310 is formed in the middle of the upper surface of the connecting seat 308, a connecting screw 311 is arranged in the inside of the screw hole 310, and the connecting screw 311 is fixedly arranged at the bottom end of the support rod 303, the support rod 303 is installed above the connecting seat 308 through the connecting screw 311 and the screw hole 310, and the support rod 303 can be removed by rotating, so that the spherical cover 304 can be replaced and cleaned, and a limiting block 312 is fixedly arranged at the top end of the support rod 303, the limiting block 312 can limit the spherical cover 304, so as to avoid that the spherical cover 304 moves upward with the sewage.

[0056] The bio-treatment agent feeding assembly 4 comprises a fixed cover 401 fixedly arranged at the top end of the upper tank body 102, a circular groove 105 is formed in the middle of the top end of the upper tank body 102, the fixed cover 401 is fixedly arranged in the inside of the circular groove 105, a rotating rod 402 is arranged in the middle of the bottom end of the fixed cover 401 through a bearing, a plurality of fan blades 403 are arranged around the outside of the rotating rod 402, the fan blades 403 rotate when the sewage flows through the fan blades 403, and the bio-treatment agent feeding assembly 4 utilizes the kinetic energy of the flowing sewage to realize automatic feeding of the bio-treatment agent.

[0057] Specifically, the top end of the rotating rod 402 is fixedly provided with a movable disc 404, and the movable disc 404 is arranged in the interior of the fixed cover 401.

The inlet groove 407 and the discharging groove 406 are arranged in a staggered manner, and the inlet groove 407 and the discharging groove 406 are matched with the feeding grooves 405. When the feeding grooves 405 on the movable disc 404 rotate to the upper side of the discharging groove 406, the biological treatment agent in the feeding grooves 405 can pass through the discharging groove 406 and enter the upper tank body 102, so that the biological treatment agent can be added.

[0058] More specifically, the inlet groove 407 is fixedly provided with a horn-shaped storage cover 408 at the notch. The storage cover 408 can store the biological treatment agent. The biological treatment agent used in the technical solution is in a powder or small block structure.

[0059] When the device is in use, sewage is transported into the biological adsorption assembly 3 through the water inlet assembly 2. The sewage is subjected to biological adsorption treatment in the biological adsorption assembly 3, and the organic matter in the sewage is adsorbed and degraded. The sewage in the biological adsorption assembly 3 is pushed into the treatment tank 1 under the action of subsequent sewage transportation. At this time, the biological treatment agent adding assembly 4 adds the biological treatment agent into the treatment tank 1. The sewage and the biological treatment agent are mixed in the treatment tank 1. At this time, the biological treatment agent can treat the nitrogen and phosphorus components in the sewage. When a certain amount of sewage is accumulated in the treatment tank 1, the treated sewage can be discharged. When the sewage is completely treated, the sediment and residual sewage generated in the sewage treatment can be discharged through the slag discharge port at the bottom end of the treatment tank 1.

[0060] When the sewage enters the water inlet assembly 2, the sewage enters the water inlet cover 201 through the water inlet pipe 203. The sewage in the water inlet cover 201 is transported into the treatment cylinder 302 through the plurality of water guide pipes 202. In this process, the electromagnetic valves in the plurality of water guide pipes 202 are opened and closed in turn to ensure that the sewage can be circulated into the plurality of treatment cylinders 302. Each treatment cylinder 302 can realize intermittent transportation of the sewage. When the sewage enters the treatment cylinder 302, the sewage can stay in the treatment cylinder 302 to ensure that the biological adsorption membrane 307 can adsorb and treat the sewage. When the subsequent sewage is transported into the treatment cylinder 302 again, the sewage in the treatment cylinder 302 that has completed the adsorption treatment enters the upper tank body 102 through the backwater pipe 204.

[0061] After the sewage enters the upper tank body 102, the sewage moves downward under the action of gravity, and in this process, the sewage flows through the fan blade 403, so that the fan blade 403 rotates, and the fan blade 403 can drive the rotating rod 402 to rotate, and the rotating rod 402 drives the movable disc 404 to rotate, and when the feeding groove 405 on the movable disc 404 rotates to below the feeding groove 405, the biological treatment agent in the storage cover 408 falls into the feeding groove 405 under the action of gravity, and when the feeding groove 405 on the movable disc 404 rotates to above the discharging groove 406, the biological treatment agent in the feeding groove 405 can pass through the discharging groove 406 into the upper tank body 102, at this time, the feeding of the biological treatment agent can be realized.

[0062] After the sewage and the biological treatment agent enter the upper tank body 102, they fall into the lower tank body 103 under the action of gravity, at this time, the stirring motor 108 drives the stirring rod 109 to rotate, and the stirring rod 109 mixes and stirs the sewage and the biological treatment agent through the stirring blade 110, so that the nitrogen and phosphorus components in the sewage are treated, and when the sewage in the lower tank body 103 accumulates to a certain amount, the sewage can be discharged through the drain pipe 106, and thus the biological treatment of the sewage can be completed.

[0063] At the same time, in the process of treating the sewage, when the sewage enters the treatment tank 1 through the backwater pipe 204, the sewage and the biological treatment agent enter the lower tank body 103 together, the connecting shaft 1091 and the rotating rod 1092 rotate synchronously, that is, the connecting shaft 1091 and the rotating rod 1092 do not rotate relative to each other, and at this time, the stirring blades 110 on the stirring rod 109 are at the same rotation angle, and the stirring blades 110 are all under the same stirring intensity, so that the sewage and the biological treatment agent are fully mixed, and in the mixing process, through the rotation of the storage hole 1101, the sewage and the biological treatment agent utilize the arc of the storage hole 1101, so that the sewage appears a small range of rotation in the lower tank body 103, which ensures that the biological treatment agent is fully utilized, and at the same time, the flow valve in the drain pipe 106 is in a closed state to avoid the discharge of the sewage.

[0064] And with the increase of the sewage treatment content, the content of the generated sediment gradually increases, that is, with the rotation of the stirring blade 110, part of the sediment accumulates in the storage hole 1101, so that the pressure sensor in the storage hole 1101 increases in pressure, and then with the increase of the pressure value of the pressure sensor, the rotation speed of the connecting shaft 1091 relative to the rotation speed of the rotating rod 1092 gradually decreases, and at the same time, with the decrease of the rotation speed of the connecting shaft 1091, the stirring blade 110 on the connecting shaft 1091 also rotates, so that the stirring blade 110 on the connecting shaft 1091 changes from the vertical state to the inclined state, and at the same time, the rotation rate of the rotating rod 1092 remains unchanged.

[0065] The sediment content of the sewage treated by the biological treatment agent is increased, and the sewage meeting the discharge requirement is located in the upper part of the connecting shaft 1091. As the sediment content is increased, the sediment content stored in the storage hole 1101 per unit area is increased, that is, the pressure of the storage hole 1101 is increased, the rotation speed of the connecting shaft 1091 is reduced, and the stirring blade 110 located on the connecting shaft 1091 is angularly rotated.

[0066] When the pressure sensor in the storage hole 1101 reaches the set maximum pressure, the connecting shaft 1091 is stationary, the rotation rate of the rotating rod 1092 is reduced, the stirring blade 110 located on the connecting shaft 1091 is parallel to the ground of the lower tank body 103, the stirring force of the stirring blade 110 on the connecting shaft 1091 on the sewage is reduced, the sewage in the lower tank body 103 is stratified by the stirring blade 110 on the connecting shaft 1091, the upper layer of the sewage tends to be stable, and the sediment in the lower layer is blocked by the stirring blade 110 on the connecting shaft 1091. At this time, the control flow valve is opened, so that the upper layer of the sewage is discharged through the drain pipe 106. At the same time, after the storage hole 1101 reaches the set maximum pressure, it means that the sediment in the lower tank body 103 affects the mixing efficiency of the new sewage and the biological treatment agent, so that when the sewage is discharged through the drain pipe 106, the electromagnetic valve of the inlet pipe 203 is in the closed state to avoid new sewage entering the treatment tank 1, and after the sewage is discharged through the drain pipe 106, the sediment and other sewage are discharged through the slag discharge port.

[0067] When the pressure sensor in the storage hole 1101 does not reach the maximum pressure, and at this time the height of the sewage has been submerged by the drain outlet of the drain pipe 106, but the sediment in the storage hole 1101 is not enough to affect the rotation of the stirring blade 110, and due to the force on the pressure sensor on the storage hole 1101, the stirring blade 110 on the connecting shaft 1091 is tilted, the angle of the stirring blade 110 is reduced, and the speed of the connecting shaft 1091 is reduced. In order to prevent the sediment in the lower tank body 103 from moving to the side of the biological treatment agent feeding assembly 4 along with the stirring blade 110, increase the difficulty of discharging sewage through the drain pipe 106, and further promote the movement of sewage to the side close to the discharge port in the stirring blade 110, the stirring blade 110 on the connecting shaft 1091 can always be used to block the sediment, and the movement direction of the sediment can be inhibited by the rotation of the stirring blade 110, so that the sediment always gathers at the bottom of the lower tank body 103, and then as the sewage content in the treatment tank 1 increases, the flow valve in the drain pipe 106 is opened in turn, that is, one is open and the other is closed, and the cycle is repeated, so that the drain pipe 106 can discharge the sewage in the upper layer of the treatment tank 1 without causing excessive interference to the rotation method of the sewage in the treatment tank 1, and can discharge the sewage in the treatment tank 1 during the sewage treatment process.

[0068] It should be noted that when the flow valve on the drain pipe 106 is in the open state, the electromagnetic valve in the backwater pipe 204 is in the closed state, so that when the drain pipe 106 discharges the treated sewage, untreated sewage cannot enter through the drain pipe 106.

[0069] In addition, in order to avoid the influence of the water pressure of the sewage on the pressure sensor in the storage hole 1101, causing the data of the control end to be disordered, and then setting the sewage in the treatment tank 1 to reach the discharge depth, and the amount of sediment in the storage hole 1101 is small, at this time the pressure received by the pressure sensor is less than the maximum pressure set by the pressure sensor, that is, at this time the pressure sensor can only control the flow valve of the drain pipe 106, when the pressure sensor in the storage hole 1101 is affected by the sediment, the pressure received by the pressure sensor is the same as the pressure when the treatment tank 1 reaches the discharge depth, and since the drain pipe 106 in the treatment tank 1 can still discharge the sewage at this time, it should be noted that the rotation angle of the stirring blade 110 on the connecting shaft 1091 is only related to the pressure value of the pressure sensor.

[0070] Through the cooperation among the stirring blade 110, the storage hole 1101 and the pressure sensor, the amount of the precipitate and the sewage depth pressure value in the storage hole 1101 are detected by the pressure sensor when the sewage and the biological treatment agent are mixed, the angle of the stirring blade 110 on the connecting shaft 1091 is controlled by the pressure value received by the pressure sensor, the stirring blade 110 can isolate the precipitate in the lower tank body 103, and the untreated sewage can be transported to the bottom of the lower tank body 103 through the inclination and the rotating direction of the stirring blade 110, the sewage can be fully mixed with the biological treatment agent, and the sewage treatment mixing rate is improved through the cooperation between the biological treatment agent and the sewage in the mixing process in the process of the rotation of the stirring blade 110.

[0071] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the foregoing embodiments of the present application are described in detail, for those skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included in the scope of protection of the present application.
