Description

Technical Field

[0001] The invention relates to the technical field of water treatment, in particular to a pollutant discharge port interception reactor. Background Art

[0002] With the rapid development of social economy, the increase of industrial discharge and domestic sewage has led to increasingly serious water pollution problems, especially the direct discharge of ammonia nitrogen-containing wastewater and other pollutants, which has become one of the important factors threatening water environmental safety and ecological balance. Ammonia nitrogen is a typical water pollutant. Its excessive discharge will cause eutrophication of water bodies, leading to excessive algae reproduction, water hypoxia and other problems, and ultimately destroy the balance of aquatic ecosystems and seriously affect the use function of water bodies. Therefore, the development of efficient and environmentally friendly water pollutant treatment technology, especially the effective removal of ammonia nitrogen pollution, has become an important research direction in the current water treatment field.

[0003] However, most of the conventional sewage treatment devices are currently used for fixed operation, and in practical applications they often lack the ability to flexibly adapt to complex water environments (such as pollutant outlets) and dynamic water flow environments (such as different water flow rates). At the pollutant outlet, the water flow rate is usually fast and the water quality fluctuates greatly, which brings multiple challenges to the existing technology. First, high flow rates may impact the treatment device, causing the device to deviate from the working position, affecting the stability and treatment efficiency of the device. Secondly, the exchange capacity between the device and the external water body is limited, and local stagnation or insufficient water flow disturbance is prone to occur, resulting in the inability of pollutants in the water body to fully contact the treatment device, reducing the purification effect. In addition, the dynamic characteristics of the pollutant outlet also require the device to be able to achieve real-time dynamic adjustment according to changes in water flow rate and pollutant concentration to ensure efficient and stable treatment effects. These problems highlight the urgency of developing a more adaptable water pollutant treatment device for complex water environments and dynamic water flow conditions. Based on the above background, the present invention provides a pollutant outlet interception reactor that can efficiently purify water bodies contaminated with ammonia nitrogen, and is suitable for pollution control of the water environment of the sewage outlet. Summary of the invention

[0004] The object of the present invention is to provide a pollutant discharge port interception reactor to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a pollutant discharge interception reactor, comprising a bioreactor, a buoyancy support body arranged on both sides of the bioreactor, and a pressure support plate above the bioreactor, characterized in that the pressure support plate is connected to the bioreactor through four pressure columns, the height of the pressure columns is less than the diameter of the fluidized filler, an ammonia nitrogen detector, a high-pressure fan, a drive structure, a solar power generation module and a pressure sensing area are arranged on the pressure support plate, the high-pressure fan is connected to the microporous aeration pipe at the bottom of the reaction tank through a high-pressure gas pipe, the microporous aeration pipe releases gas to the water body through the aeration holes to provide oxygen and power, the solar power generation module stores electricity through the power storage unit, and distributes electricity through the main control unit to control the high-pressure fan, the drive structure and the ammonia nitrogen detector.

[0006] According to the above technical solution, the front and rear tank bodies of the bioreactor are provided with through holes, and the lower half of the front tank body is provided with a movable flow velocity measurement plate, which is connected to the conduction rod and perpendicular to the bottom plate of the reactor tank, and the conduction rod is connected to the pressure sensing area. When the water flow rate in front of the bioreactor is too large, the flow velocity measurement plate opens a certain angle according to the impact force received, and conducts the water impact force to the pressure sensing area through the conduction rod. When the water impact force is greater than the set pressure value, the main control unit will increase the power of the high-pressure fan, thereby increasing the gas output of the high-pressure gas pipe, so as to increase the aeration speed and stabilize the tank body. In addition, the interior of the bioreactor is filled with fluidized filler, and the particle size of the fluidized filler is greater than the diameter of the through hole, so as to prevent the fluidized filler from being lost when the water inside and outside the bioreactor is exchanged.

[0007] According to the above technical solution, the driving structure is connected with a first telescopic rod and a second telescopic rod, wherein a sampling box is arranged on the top of the first telescopic rod, and a sealing plug is arranged on the top of the second telescopic rod, and the sealing plug fits with the bottom groove of the sampling box at the bottom of the sampling box.

[0008] According to the above technical solution, a sampling box telescopic hole is provided on the top of the sampling box, and the diameter of the sampling box telescopic hole is the same as the diameter of the second telescopic rod.

[0009] According to the above technical solution, the buoyancy support body can move the bioreactor on the water surface with the wind, thereby enhancing the exchange efficiency of water through the through holes.

[0010] According to the above technical solution, the microporous aeration pipe is diagonally arranged on the bottom plate of the reaction tank to uniformly release oxygen into the water body, and the microporous aeration pipe is connected to the high-pressure gas pipe through the gas delivery pipe.

[0011] According to the above technical solution, the solar power generation module is connected to the power storage unit through a cable, the power storage unit transmits power to the main control unit through the power transmission line, and the main control unit controls the operation of the high-pressure fan, the drive structure and the ammonia nitrogen detector through the fan control cable, the drive structure control cable and the ammonia nitrogen detector control cable respectively.

[0012] According to the above technical solution, the main control unit automatically uploads the water body data detected by the ammonia nitrogen detector.

[0013] According to the above technical solution, water-purifying microorganisms grow on the surface of the fluidized filler, and when the oxygen supply conditions are sufficient, simultaneous nitrification and denitrification can be achieved, thereby efficiently removing pollutants such as ammonia nitrogen in the water.

[0014] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: the present invention, through core components such as a biological reactor, a buoyancy support body, a pressure support plate, a fluidized filler, a microporous aeration tube and a high-pressure fan, achieves efficient removal of pollutants such as ammonia nitrogen in water bodies through the synergistic effect of the fluidized filler and the aeration system. At the same time, the reactor integrates a solar power generation module, a main control unit and a telescopic sampling device, which can perform real-time sampling and ammonia nitrogen detection on pollutants in different water layers, and automatically adjust the fan operation and oxygen distribution according to changes in water speed, which is suitable for efficient pollution control in complex water environments.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Embodiment 1:

[0029] like Figure 1As shown: a pollutant discharge port interception reactor, comprising a bioreactor 1, buoyancy support bodies 3 arranged on both sides of the bioreactor 1, and a pressure support plate 14 above the bioreactor 1, the pressure support plate 14 is connected to the bioreactor 1 through four pressure columns, the height of the pressure column is less than the diameter of the fluidized filler 6 to prevent the fluidized filler 6 from flowing out from above, an ammonia nitrogen detector 23, a high-pressure fan 24, a drive structure 10 and a solar power generation module 25 are arranged above the pressure support plate 14, the high-pressure fan 24 is connected to the high-pressure gas pipeline 5, a control box 20 is arranged on the left side of the solar power generation module 25, and is used to control the electrical equipment in the pollutant discharge port interception reactor, and the ammonia nitrogen detector 23 is used to detect ammonia nitrogen in the water body in the bioreactor 1;

[0030] like Figure 2 , Figure 3 as well as Fig. 9 As shown, the top of the bioreactor 1 is semi-open, and it keeps a certain distance from the pressure support plate 14. The front and rear tank bodies of the bioreactor 1 are provided with through holes 2, and the lower half of the front tank body is provided with a movable flow velocity measurement plate 29, which is connected to a conduction rod 30 and is perpendicular to the bottom plate 9 of the reactor. The conduction rod 30 is connected to a pressure sensing area 28, and a pressure sensor is provided in the pressure sensing area 28. When the water flow rate in front of the bioreactor 1 is too large, the flow velocity measurement plate 29 opens a certain angle according to the impact force received, and transmits the water impact force to the pressure sensing area 28 through the conduction rod 30. When the water impact force is greater than the set pressure value (the pressure value is set by the operator on the main control unit 27), the main control unit 27 will increase the power of the high-pressure fan 24, thereby increasing the gas output of the high-pressure gas transmission pipe 5; in addition, the interior of the bioreactor 1 is filled with a fluidized filler 6, The particle size of the fluidized filler 6 is larger than the diameter of the through hole 2 to prevent the fluidized filler 6 from being lost when the water inside and outside the biological reaction tank 1 is exchanged. Buoyancy supports 3 are arranged on both sides of the biological reaction tank 1, so that the biological reaction tank 1 can float on the water surface. A reaction tank bottom plate 9 is arranged at the bottom of the biological reaction tank 1. Four microporous aeration pipes 4 are arranged in the reaction tank bottom plate 9, which are arranged diagonally. A high-pressure delivery pipe 5 is arranged in the middle of the reaction tank bottom plate 9, and the gas generated by the high-pressure fan 24 is transported by it. The bottom of the high-pressure delivery pipe 5 is connected to the gas delivery pipe 8 and the gas is transported to the microporous aeration pipe 4, and finally discharged through the aeration hole 7. The discharged gas is used to supply oxygen to the water body and the water purification microorganisms growing on the surface of the fluidized filler 6, and provide the power for the fluidization of the fluidized filler 6, so as to finally achieve the purpose of purifying water quality. In addition, the high-pressure delivery pipe 5 is also connected to the reaction tank stabilizing pipe 31, and the reaction tank stabilizing pipe 31 is used to keep the biological reaction tank 1 stable;

[0031] like Figure 4As shown: the power of the high-pressure fan 24 is controlled by the control box 20, and the control box 20 is installed with a main control unit 27 and a power storage unit 15. The power storage unit 15 is connected to the solar power generation module 25 through a cable. The power generated by the solar power generation module 25 is stored by the power storage unit 15. When the power storage is full, the power is transmitted to the main control unit 27 through the power transmission line 16, and the power is distributed by the main control unit 27. The main control unit 27 controls the working states of the high-pressure fan 24, the drive structure 10, and the ammonia nitrogen detector 23 through the fan control cable 17, the drive structure control cable 18, and the ammonia nitrogen detector control cable 19 respectively;

[0032] like Figure 5 As shown: the driving structure 10 controls the telescopic process of the first telescopic rod 11 and the second telescopic rod 12. The diameter of the first telescopic rod 11 is the same as the aperture of the pressure support plate at the connection between the driving structure 10 and the first telescopic rod 11, so that the first telescopic rod 11 can be telescoped. The top of the first telescopic rod 11 is a sampling box 21, and the two are welded together. The second telescopic rod 12 is arranged inside the first telescopic rod 11, and the top of the second telescopic rod 12 is a sealing plug 13. The diameter of the sealing plug 13 is the same as the diameter of the second telescopic rod 12, and the length of the first telescopic rod 11 is the same as the length of the second telescopic rod 12. The maximum telescopic distance is the distance when the bottom of the sampling box 21 intersects with the bottom plate 9 of the reaction tank, and the minimum telescopic distance is the distance when the top of the sampling box 21 intersects with the pressure support plate 14.

[0033] like Figure 6-8 As shown: a sampling box telescopic hole 26 is provided at the top of the sampling box 21, and its hole diameter is the same as the diameter of the second telescopic rod 12; a sampling box bottom groove 22 is provided at the bottom of the sampling box 21, which fits with the top sealing plug 13 of the second telescopic rod 12.

[0034] During the use of the device, the solar power generation module 25 generates electricity through solar energy, and then transmits the generated electricity to the power storage unit 15 through a cable. The power storage unit 15 transmits the electricity to the main control unit 27, and finally the main control unit 27 controls the device electrically. First, the fan control cable 17 is used to transmit the electricity to the high-pressure fan 24. After the high-pressure fan 24 is powered on, the generated high-pressure gas is transmitted to the gas delivery pipe 8 through the high-pressure delivery pipe 5. Subsequently, it is discharged through the microporous aeration pipe 4, the aeration hole 7 and the reactor stabilization pipe 31. The air discharged from the aeration hole 7 contacts the water body and the fluidized filler 6 inside the biological reactor 1. When the oxygen supply conditions are sufficient, the fluidized filler 6 can exist stably, realizing simultaneous nitrification and denitrification, thereby efficiently purifying the water quality.

[0035] The buoyancy support plates 14 arranged at both ends of the bioreactor 1 can swing up and down on the water surface under the influence of wind, so that the bioreactor 1 moves relative to the water body. This movement helps the water body to achieve more complete internal and external exchange through the through hole 2, thereby improving the treatment effect of the device on pollutants in the water body. In addition, the swinging can also prevent local water stagnation and further optimize the purification efficiency. The telescopic rod controlled by the driving structure 10 can collect water from different water layers as samples for testing. During the sinking of the first telescopic rod 11, the second telescopic rod 12 maintains the same movement, and the top sealing plug 13 of the second telescopic rod 12 is always in line with the bottom groove 22 of the sampling box during the descending movement. When the first telescopic rod 11 and the second telescopic rod 12 reach the predetermined sampling depth, the sealing plug 13 retracts, and the water at the predetermined depth flows into the sampling box 21 under pressure. Subsequently, the sealing plug 13 is in line with the bottom groove 22 of the sampling box. At this time, the sampling is completed. The water collected in the sampling box 21 is finally detected by the ammonia nitrogen detector 23, and the main control unit 27 uploads the water body data detected by the ammonia nitrogen detector 23. At night, the power stored in the power storage unit 15 is started, and the power is only supplied to the high-pressure fan 24.

[0036] Embodiment 2: When the device is placed at a sewage outlet for use, the front of the bioreactor 1 must face the sewage outlet. Since the water flow rate at the sewage outlet is too high, it will cause an impact on the bioreactor 1, causing the bioreactor 1 to move away from the sewage outlet, reducing its water purification capacity. Therefore, when the water flow rate is too high, the flow rate measurement plate 29 will transmit the impact force to the pressure sensing area 28 through the conduction rod 30, thereby increasing the power of the high-pressure fan 24. At this time, the gas generated by the high-pressure fan 24 becomes more, and the gas is transmitted to the microporous aeration pipe 4 and the reactor stabilizing pipe 31 through the high-pressure gas transmission pipe 5 and the gas transmission pipe 8. Since the pipe mouth of the reactor stabilizing pipe 31 faces the rear of the bioreactor 1, it will eventually cause the aeration speed of the bioreactor 1 to increase and generate a backward thrust, thereby stabilizing the tank body.
