Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a quantitative dosing device for sludge reduction bacteria. Background Technology

[0002] Wastewater treatment is the process of removing or degrading pollutants in wastewater through physical, chemical, and biological technologies to ensure that the water quality meets discharge standards and ultimately achieves safe discharge or resource utilization of wastewater. Sludge is an inevitable byproduct of wastewater treatment. By quantitatively adding sludge-reducing bacteria, the organic matter in the sludge can be decomposed by microorganisms, reducing the amount of excess sludge, lowering dewatering and disposal costs, improving wastewater treatment efficiency, and reducing energy consumption and environmental costs.

[0003] In existing technologies, sludge reduction bacteria technology combines multiple types of bacteria into a composite microbial agent. Through a unique biodegradation mechanism, it achieves the dual goals of sludge reduction and wastewater purification. When using sludge reduction bacteria quantitative dosing equipment, the sludge reduction bacteria stock solution and dilution water need to be injected into a solution tank in a specific ratio and mixed using a mixer to form a bacterial solution. However, existing solution tanks only serve a single storage function. During storage, the bacterial solution is exposed to air for extended periods, which can easily cause some bacteria, such as aerobic bacteria, to over-metabolize, consuming nutrients and promoting the growth of other bacteria, reducing the stability of the bacterial solution. This leads to a significant decrease in metabolic capacity after subsequent additions, affecting the final treatment effect.

[0004] Therefore, we propose a quantitative dosing device for sludge reduction bacteria to solve the problems mentioned in the background art. Summary of the Invention

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. In use, the nitrogen injection pipe works in conjunction with the air inlet pipe to inject nitrogen into the solution tank. Air is then expelled from the solution tank via the oxygen venting pipe, while an oxygen sensor monitors the oxygen content. One second metering pump delivers a measured amount of raw solution to the solution tank, while another second metering pump delivers dilution water to a vacuum degasser for air removal, forming deoxygenated water, which is then delivered to the solution tank. During injection, a small amount of nitrogen in the solution tank is released through a pressure balancing valve to maintain stable pressure. A temperature sensor and temperature control module work together to heat / cool the liquid, stabilizing the bacterial solution temperature within a suitable range. The nitrogen venting combined with the deoxygenated water creates a low-oxygen environment. This low-oxygen environment keeps the sludge reduction bacteria in a "low-metabolic dormant state," preventing activity loss and protecting their activity. The anaerobic environment also inhibits the growth of other bacteria and putrefactive bacteria, ensuring the safety of subsequent additions.

[0019] 2. In use, the dual-axis motor is started, driving the rotating shaft and gear roller to rotate, which in turn drives the arc-shaped toothed plate and the elastic insulation layer to rotate. When passing through the extrusion sleeve, the elastic insulation layer is compressed and deformed, shrinking into the arc-shaped plate. The forward and reverse motors are started, driving the drive gear and the upper toothed annular plate to rotate, which in turn drives the toothed skeleton, the annular skeleton, and the sliding skeleton to rotate. This causes the low-friction insulation layer and the LED light guide light to slowly rotate on the outer surface of the solution tank, allowing the bacterial solution in all areas of the solution tank to receive suitable light, making the overall activity of the bacterial solution more uniform. Full-range illumination can be achieved without opening the solution tank, without disrupting the low-oxygen protective atmosphere inside the tank. At the same time, the low-friction insulation layer keeps the bacterial solution warm, achieving integrated functions of light supplementation and heat preservation.

[0020] 3. In use, the inner wall of the lampshade is coated with a microprism diffuse reflection coating, which can reduce light intensity deviation. Diffuse reflection can also reduce local light intensity, protect the photoreaction system of photosynthetic bacteria, and improve the viability retention rate. The light from the LED light guide lamp first shines on the transparent light guide layer, and then the light is transmitted to the diffusion point on the inner wall of the solution tank through the internal fiber micro-bundle. The diffusion point adopts a "hemispherical microlens" structure, which scatters the light towards the middle part of the solution tank, which facilitates the light supplementation of the bacterial solution in the middle part. There is no need to change the position of the light source. Deep irradiation can be achieved directly through light guiding, which is suitable for low oxygen environment. Combined with rotation irradiation, full-volume bacterial solution light coverage can be achieved. Attached Figure Description

Detailed Implementation

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Example 1: Please refer to Figures 1-13As shown, the present invention provides a technical solution: a sludge reduction bacteria quantitative dosing device, including a raw material supply component 1, an anaerobic dosing component 2 disposed on the front surface of the raw material supply component 1, and a light supplement component 3 movably sleeved on the outer surface of the anaerobic dosing component 2; the anaerobic dosing component 2 includes an upper dosing tank 201 and a lower dosing tank 209, a transparent light guide layer 210 fixedly installed between the upper dosing tank 201 and the lower dosing tank 209, a temperature control module 223 fixedly installed at the bottom of the lower dosing tank 209, and a temperature sensor at the bottom of the lower dosing tank 209. Sensor 212, nitrogen injection pipe 206 is provided at the bottom of the lower injection tank 209, nitrogen injection electric valve 207 is provided at the top of nitrogen injection pipe 206, and air inlet pipe 208 is fixedly connected to the output end of nitrogen injection electric valve 207. Oxygen sensor 213 is provided at the edge of the top of the upper injection tank 201. Oxygen discharge pipe 218 and pressure relief pipe 220 are respectively connected to the top of the upper injection tank 201 away from oxygen sensor 213. Oxygen discharge electric valve 219 is provided on the outer surface of oxygen discharge pipe 218, and pressure balance valve 221 is provided on the outer surface of pressure relief pipe 220. The outer surface of the lower dosing tank 209 is equipped with a first metering pump 203 and an intelligent control system 202. The input end of the first metering pump 203 is connected to a metering tube 222 via a flange. The bottom of the lower dosing tank 209 is fixedly connected to a dosing pipe 204. One end of the dosing pipe 204 is connected to a dosing electric valve 205 via a flange. The output end of the dosing electric valve 205 is connected to one end of the metering tube 222 via a farad plate. The raw material supply assembly 1 includes two second metering pumps 101. The output end of one of the second metering pumps 101 is connected to a vacuum degasser 102 via a pipe. The output ends of the vacuum degasser 102 and the other second metering pump 101 are both fixedly connected to raw material pipes 103. The outer surface of both raw material pipes 103 is equipped with a supply electric valve 104. One end of both raw material pipes 103 is connected to a feed pipe 105 via a flange. One end of each of the two feed pipes 105 is fixedly connected to the top of the upper feeding tank 201. Support frames are fixedly installed on the outer surfaces of the two raw material pipes 103. The top of the air inlet pipe 208 is fixedly connected to the bottom of the lower feeding tank 209. A stirring motor 215 is fixedly installed on the top of the upper feeding tank 201. A stirring paddle 216 is fixedly installed on the output end of the stirring motor 215. A sealing element 217 is provided on the outer surface of the top of the stirring paddle 216. A sealing hole 214 is opened at the center of the top of the upper feeding tank 201. The outer surface of the sealing element 217 is fixedly connected to the inner wall of the sealing hole 214. The detection end of the temperature sensor 212 is fixedly inserted through the lower feeding tank 209 to the interior of the transparent light guide layer 210.

[0038] In this embodiment, during use, the oxygen venting electric valve 219, pressure balancing valve 221, nitrogen injection electric valve 207, dosing electric valve 205, and two supply electric valves 104 are all in the closed state. The bottom end of the nitrogen injection pipe 206 is connected to an external nitrogen injection device. The upper dosing tank 201, the transparent light guide layer 210, and the lower dosing tank 209 form a solution tank. The intelligent control system 202 activates the nitrogen injection electric valve 207 and the oxygen venting electric valve 219, and nitrogen is delivered to the nitrogen injection pipe 206 through the nitrogen injection device. Nitrogen is injected into the lower dosing tank 209 through the air inlet pipe 208 and flows upward, discharging the oxygen in the solution tank upward. The air in the solution tank is then discharged through the oxygen venting pipe 218. Simultaneously, oxygen sensor 213 detects the oxygen content in the solution tank and transmits the detected oxygen data to intelligent control system 202 via electrical signals for identification and analysis. When the oxygen data matches the set working threshold, it is determined that the oxygen in the solution tank has been basically eliminated. Then, intelligent control system 202 controls the nitrogen injection equipment and nitrogen injection electric valve 207 to close, stopping nitrogen injection. The input ends of the two second metering pumps 101 are connected to the external sludge reduction bacteria stock solution supply equipment and dilution water supply equipment through pipelines, respectively. The raw material pipe 103 consists of multiple detachable pipes. Two second metering pumps 101 and two supply electric valves 104 are activated, delivering a measured amount of stock solution to the solution tank through one of the raw material pipes 103 and the corresponding feed pipe 105. Simultaneously, dilution water is delivered to the vacuum degasser 102. The vacuum degasser 102 includes a vacuum degassing module, an inlet / outlet water system, a gas-liquid separation system, and a liquid level detection system. The vacuum degassing module removes air from the dilution water, forming deoxygenated water. This deoxygenated water is then delivered to the other raw material pipe 103 through the inlet / outlet water system and then to the solution tank through the corresponding feed pipe 105. During the injection process, a small amount of nitrogen in the solution tank can be discharged through the pressure balance valve 221 to maintain stable pressure. The stirring motor 215 is activated, driving the stirring paddle 216 to rotate, causing the stock solution and deoxygenated water to be stirred under a slightly positive pressure environment, forming a bacterial solution. The sealing element 217 improves the sealing of the solution tank during stirring, reducing air ingress. The temperature sensor 212 detects the liquid temperature and transmits the detected temperature data to the intelligent control system 202 for judgment. This triggers the temperature control module 223 to heat / cool the liquid, stabilizing the bacterial solution temperature within a suitable range and reducing temperature fluctuations. Under the action of the anaerobic dosing component 2, nitrogen is injected to remove oxygen before preparing the bacterial solution, maintaining a slightly positive pressure within the solution tank. Nitrogen is an inert gas and does not change key environmental parameters such as pH and osmotic pressure of the bacterial solution. Nitrogen forms an "inert gas protective layer" on the surface of the bacterial solution, preventing oxygen from the air from re-entering the solution and maintaining a low-oxygen environment. Simultaneously, the slightly positive pressure within the solution tank further inhibits oxygen permeation.Under the action of raw material supply component 1, the oxygen content in the bacterial solution is reduced from the source by vacuum degassing the dilution water, preventing oxygen from the dilution water from entering the bacterial solution and further strengthening the low-oxygen protection. Nitrogen deoxygenation combined with deoxygenated water creates a low-oxygen environment. This low-oxygen environment puts the sludge reduction bacteria in a "low-metabolic dormant state," avoiding activity loss. After addition, the bacteria can quickly recover to their initial activity (without additional activation steps), protecting the activity of the sludge reduction bacteria. The anaerobic environment can also inhibit the growth of miscellaneous bacteria and putrefactive bacteria. The bacterial solution will not produce odors or toxic substances due to storage, ensuring the safety of subsequent additions, extending the storage time, and improving the addition effect. This solves the problem that the solution tank in sludge reduction bacteria quantitative addition equipment generally only has a storage function. When the bacterial solution is in contact with air for a long time, it is easy for some bacteria to over-metabolize, consume nutrients, and breed miscellaneous bacteria, reducing the stability of the bacterial solution and causing a significant decrease in metabolic capacity after subsequent additions. Start the first metering pump 203 and the dosing electric valve 205, and the bacterial solution is transported to the metering tube 222 through the dosing tube 204. The first metering pump 203 can then output the measured amount of bacterial solution.

[0039] Example 2: Figures 6-13As shown, the illumination supplement component 3 includes a sliding frame 301 and a toothed frame 302. An annular frame 303 is fixedly installed between the opposite sides of the sliding frame 301 and the toothed frame 302.

The inner walls of the first guide rail 312 and the second guide rail 325 are respectively fixedly installed on the outer surfaces of the lower dosing tank 209 and the upper dosing tank 201. A rotating plate 315 is movably embedded inside each of the two arc-shaped plates 305. An elastic insulation layer 316 is fixedly connected to the inner wall of each of the two rotating plates 315. Two arc-shaped toothed plates 320 are fixedly installed on the outer surface of each of the two rotating plates 315. A dual-axis motor 321 is fixedly installed on the outer surface of each of the two arc-shaped plates 305. A rotating shaft 322 is fixedly installed on the two output ends of each of the two dual-axis motors 321. Gear rollers 323 are fixedly installed on the outer surface of each of the four rotating shafts 322. A pressing sleeve rod 319 is movably embedded at the inner edge of each of the two arc-shaped plates 305. A fixing rod 318 is movably embedded inside each of the two pressing sleeve rods 319.Each of the two arc-shaped plates 305 has four grooves 313 on its outer surface and two connecting holes 314 on its outer surface. Each of the two rotating plates 315 has eight limiting rods 317 fixedly installed on its outer surface. Each pair of adjacent limiting rods 317 forms a group. The outer surfaces of the eight groups of limiting rods 317 are movably embedded in the eight grooves 313. The outer surfaces of the four gear rollers 323 are movably embedded in the four connecting holes 314. The outer surfaces of the four gear rollers 323 are meshed with the outer surfaces of the four arc-shaped toothed plates 320. One end of each of the four rotating shafts 322 is movably fitted with a fixing block 324. The outer surfaces of the four fixing blocks 324 are fixedly installed on the outer surfaces of the two arc-shaped plates 305. One end of each of the two fixing rods 318 is fixedly installed on the opposite side of the sliding frame 301 and the annular frame 303. The inner wall of the low-friction insulation layer 304 is in contact with the outer surfaces of the upper dosing tank 201, the transparent light guide interlayer 210, and the lower dosing tank 209. The edge of the outer surface of the low-friction insulation layer 304 is fixedly connected to the outer surfaces of the two arc-shaped plates 305. The outer surfaces of the two elastic insulation layers 316 are attached to one side, and the outer surfaces of the two rotating plates 315 are in contact. The outer surfaces of the four arc-shaped toothed plates 320 are respectively movably embedded inside the two arc-shaped plates 305. The inner walls of the two elastic insulation layers 316 are in contact with the outer surfaces of the upper dosing tank 201, the transparent light guide interlayer 210, and the lower dosing tank 209.

[0040] In this embodiment, during use, two dual-axis motors 321 are activated, driving two rotating shafts 322 to rotate simultaneously via their outputs. This, in turn, drives two gear rollers 323 to rotate within their corresponding connecting holes 314, which in turn drives the meshing arc-shaped toothed plate 320 to rotate inwards into the arc-shaped plate 305. Simultaneously, this causes the rotating plate 315 to rotate. At this time, the elastic insulation layer 316 rotates along with it and passes through the compression sleeve 319. As the compression sleeve 319 rotates on the outer surface of the fixed rod 318, the elastic insulation layer 316 is deformed by the compression sleeve 319, shrinking together and rotating inwards into the arc-shaped plate 305. At the same time, another elastic insulation layer 316 is compressed and shrinks, entering another arc-shaped plate 305. When the two dual-axis motors 321 automatically shut off, the space between the two arc-shaped plates 305 opens, removing the obstruction between the LED light guide lamp 307 and the transparent light guide interlayer 210, facilitating subsequent activation of the LED light guide lamp 307 for supplemental lighting. The two dual-axis motors 321 are restarted, this time their output ends rotate in reverse, driving the gear roller 323 to rotate in reverse, causing the corresponding transversely aligned arc-shaped toothed plates 320 to move relative to each other. This, through the rotating plate 315, causes the two elastic insulation layers 316 to rotate out from the arc-shaped plate 305. After the elastic insulation layers 316 rotate out, they automatically return to their unfolded state due to their high resilience. Figure 13As shown, at this time, the two elastic insulation layers 316 are in contact with the outer surface of the solution tank and work together with the low friction insulation layer 304 to form a complete insulation sleeve, avoiding the influence of external temperature on the bacterial solution. With the help of the temperature control module 223, the viability rate is greatly improved.

[0041] Furthermore, the LED light guide lamp 307 and the forward / reverse motor 310 are activated. The LED light guide lamp 307 provides suitable illumination to the bacterial solution in the solution tank through the transparent light guide layer 210, maintaining the activity of the bacterial solution and improving the subsequent degradation rate of organic matter in the sludge. The inner wall of the lamp cover 306 is coated with a microprism diffuse reflection coating, which helps to convert the "directional light" of the LED light guide lamp 307 into "all-angle diffuse light", avoiding local light loss caused by the fixed position of the light source, reducing light intensity deviation, and the diffuse reflection can also reduce the local light intensity (avoiding direct strong light from a single point), protecting the photoreaction system of photosynthetic bacteria (some photosynthetic bacteria will be photoinhibited when exposed to strong light for a long time), and improving the viability retention rate. The transparent light guide layer 210 is made of high-transmittance quartz glass and nano-light guide particles. The transparent light guide layer 210 has an internal fiber optic micro-bundle. The light from the LED light guide lamp 307 first shines on the transparent light guide layer 210, and then the light is transmitted to the diffusion point 211 on the inner wall of the solution tank through the internal fiber optic micro-bundle. The diffusion point 211 adopts a "hemispherical microlens" structure, which scatters the light into the interior (middle part) of the solution tank, which facilitates the light supplementation of the bacterial liquid in the middle part. There is no need to change the position of the light source. Deep irradiation can be achieved directly through light guide, which is suitable for low oxygen environment. Combined with rotation irradiation, it can achieve full volume bacterial liquid light coverage.

[0042] Furthermore, the bottom of the toothed skeleton 302 is engaged with the top of the upper toothed annular plate 308, as shown below. Figure 8 As shown. After the forward and reverse motor 310 starts, it drives the upper toothed annular plate 308 to rotate on the outer surface of the first guide rail 312 via the drive gear 311, and drives the toothed frame 302 to rotate together. The annular frame 303 drives the sliding frame 301 to rotate on the outer surface of the second guide rail 325, thereby driving the low-friction insulation layer 304 and the LED light guide lamp 307 to rotate slowly on the outer surface of the solution tank. This allows the bacterial solution in each area of ​​the solution tank to receive suitable light, making the overall activity of the bacterial solution more uniform. Full-range illumination can be achieved without opening the solution tank, without disrupting the low-oxygen protective atmosphere inside the tank. At the same time, the low-friction insulation layer 304 keeps the bacterial solution warm without removing the insulation sleeve, achieving integrated functions of light supplementation and heat preservation. The inner wall of the low-friction insulation layer 304 is coated with polytetrafluoroethylene, which has a low coefficient of friction. With slow rotation, the frictional heat generation is negligible and will not affect the bacterial solution.

[0043] The overall effect and working principle of the mechanism are as follows: The intelligent control system 202 activates the nitrogen injection electric valve 207 and the oxygen venting electric valve 219. The nitrogen injection equipment delivers nitrogen to the nitrogen injection pipe 206, injects it into the lower addition tank 209 through the air inlet pipe 208, and allows it to flow upwards. Air is then vented from the solution tank through the oxygen venting pipe 218. Simultaneously, the oxygen sensor 213 detects the oxygen content in the solution tank. When the oxygen data matches the set working threshold, it is determined that the oxygen in the solution tank has been largely eliminated. Then, the intelligent control system 202 controls the nitrogen injection equipment and the nitrogen injection electric valve 207 to close, stopping the nitrogen injection. Two second metering pumps 101 and two supply electric valves 104 are activated. One raw material pipe 103 and the corresponding feed pipe 105 deliver a fixed amount of raw solution to the solution tank. Simultaneously, dilution water is delivered to the vacuum degasser 102 for air removal, forming deoxygenated water, which is then delivered to the solution tank through the other raw material pipe 103 and feed pipe 105. During injection, nitrogen gas in the solution tank can be discharged in small amounts through the pressure balancing valve 221 to maintain stable pressure. The stirring motor 215 is started, driving the stirring paddle 216 to rotate, causing the stock solution and deoxygenated water to be stirred under a slightly positive pressure environment to form a bacterial solution. The temperature sensor 212 detects the liquid temperature and transmits the detected temperature data to the intelligent control system 202 for judgment, triggering the temperature adjustment module 223 to heat / cool the liquid, stabilizing the bacterial solution temperature within a suitable range. The first metering pump 203 and the dosing electric valve 205 are started, delivering the bacterial solution to the metering tube 222 through the dosing pipe 204, and the first metering pump 203 then outputs a measured amount of bacterial solution. Two dual-axis motors 321 are activated. The outputs of the dual-axis motors 321 drive two rotating shafts 322 and two gear rollers 323 to rotate, which in turn drives the arc-shaped toothed plate 320 and the rotating plate 315 to rotate. This causes the elastic insulation layer 316 to be compressed and deformed as it passes the compression sleeve 319, shrinking into the arc-shaped plate 305. At the same time, another elastic insulation layer 316 is compressed and shrinks, entering another arc-shaped plate 305. The LED light guide lamp 307 and the forward and reverse motor 310 are activated. The LED light guide lamp 307 provides suitable light to the bacterial solution in the solution tank through the transparent light guide interlayer 210, maintaining the activity of the bacterial solution. The forward and reverse motor 310 drives the drive gear 311 to rotate the upper toothed annular plate 308, and drives the toothed skeleton 302, the annular skeleton 303 and the sliding skeleton 301 to rotate together. This causes the low-friction insulation layer 304 and the LED light guide lamp 307 to slowly rotate on the outer surface of the solution tank, ensuring that the bacterial solution in all areas of the solution tank receives suitable light.
