Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and in particular to a combined wastewater treatment device. Background Technology

[0002] With socio-economic development and population growth, the discharge of industrial wastewater and domestic sewage is increasing daily, putting enormous pressure on the water environment. Effectively treating various types of wastewater to meet discharge standards or for reuse has become a key issue in environmental protection and sustainable development. Among existing wastewater treatment technologies, biological treatment is widely used due to its economy and efficiency, with combined anaerobic and aerobic processes being particularly important. Anaerobic treatment is mainly used to remove organic matter, perform denitrification, and release phosphorus, while aerobic treatment is mainly responsible for further degrading COD, performing nitrification, and absorbing phosphorus. Combining the two can systematically and efficiently remove pollutants such as carbon, nitrogen, and phosphorus from wastewater.

[0003] Currently, common combined wastewater treatment devices or systems typically arrange anaerobic reactors and aerobic reactors in series as independent units. This results in problems such as large footprint, complex process flow connections, and high infrastructure and operating costs. In addition, in the aerobic treatment unit, providing sufficient and uniform oxygen to aerobic microorganisms is the core to ensure treatment efficiency. However, traditional aeration methods are prone to uneven air distribution due to sludge deposition or blockage, which affects the treatment effect and is inconvenient to maintain.

[0004] Meanwhile, in the biological treatment process, the activity and state of microorganisms in the reactor directly determine the treatment efficiency. However, most of the biological packing materials or microbial carriers in existing devices are fixedly installed inside the reactor. When it is necessary to observe the growth status of the microbial community, the formation of biofilm, or to perform operations such as replacing, replenishing, or sampling microorganisms, it is often necessary to shut down the reactor and empty it. This process is cumbersome, which not only affects continuous operation but also increases the difficulty and cost of maintenance. On the other hand, the effluent quality after wastewater treatment needs to be monitored in real time or periodically to ensure that it meets the standards. Existing online monitoring systems usually immerse the sensors directly in the effluent flow or use intermittent sampling methods. The former makes the sensors susceptible to contamination and interference, resulting in poor long-term stability; the latter makes it difficult to achieve truly continuous monitoring and creates data blind spots. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention discloses a combined wastewater treatment device that features high integration, efficient operation, convenient maintenance, and excellent monitoring capabilities. The technical solution adopted by this invention is as follows: A combined wastewater treatment device includes a main body structure for supplying oxygen to aerobic bacteria. The main body structure includes a base plate, on which a frame is fixedly mounted. A vertical shaft is rotatably mounted on the frame. The main body structure is equipped with a discharge mechanism for discharging and detecting wastewater, and two treatment mechanisms for treating wastewater with anaerobic bacteria and aerobic bacteria, respectively. The upper treatment mechanism is used for anaerobic bacterial treatment of sewage, and the lower treatment mechanism is used for aerobic bacterial treatment of sewage. The treatment mechanism includes an inner plate fixedly installed in the base plate, an inner hollow column rotatably installed on the inner plate, and a treatment cylinder fixedly installed in the base plate. The inner hollow column of the lower treatment mechanism has an inner hollow structure and multiple air inlets are provided on the inner hollow column.

[0006] Furthermore, the main structure includes a top motor fixedly installed on the frame, the motor shaft of the top motor being fixedly installed with the vertical shaft, a high-pressure air pipe fixedly installed on the base plate, the high-pressure air pipe being connected to an external air unit, a horizontal air pipe fixedly installed on the high-pressure air pipe, the horizontal air pipe having an internal hollow structure, the internal hollow column being rotatably installed with the horizontal air pipe, and multiple air vents being provided on the high-pressure air pipe, the air vents being located in the horizontal air pipe, and the air inlet being located in the horizontal air pipe.

[0007] The top motor drives the vertical shaft to rotate, and high-pressure air is introduced into the high-pressure air pipe through the external air blower. The air then enters the horizontal air pipe through the vent, enters the inner column of the lower processing mechanism through the air inlet, and is then ejected through the air outlet.

[0008] Furthermore, the processing mechanism also includes a top gear fixedly installed on the inner hollow column. The vertical shaft drives the top gear to rotate through gear transmission. Multiple levers are fixedly installed below the inner hollow column. The levers fit against the bottom of the processing cylinder. An arc-shaped sliding groove is provided on the inner plate.

[0009] Furthermore, the lever of the processing mechanism located below has a hollow structure and multiple air vents.

[0010] Furthermore, two vertical guide columns are slidably installed inside the arc-shaped chute. A connecting rod is fixedly installed on the vertical guide column, and a microbial disk is slidably installed on the vertical guide column. Multiple microbial placement columns are fixedly installed below the microbial disk, and four layers of microbial placement frames are fixedly installed on the microbial placement columns. Several slots are provided on the microbial placement frames. Anaerobic bacteria are placed in the microbial placement frames of the upper processing mechanism, and aerobic bacteria are placed in the microbial placement frames of the lower processing mechanism.

[0011] Furthermore, a long rotating rod is rotatably mounted on the connecting rod and the microbial disk, a short rotating rod is rotatably mounted on the long rotating rod, an internally threaded cylinder is rotatably mounted on the short rotating rod, a connecting sleeve is rotatably mounted on the long rotating rod, a lead screw is rotatably mounted inside the connecting sleeve, and a knob is fixedly mounted on the lead screw. The internally threaded cylinder and the lead screw form a threaded transmission.

[0012] The upper treatment unit contains anaerobic bacteria in its bacterial release box, while the lower treatment unit contains aerobic bacteria in its bacterial release box. Wastewater first enters the treatment cylinder of the upper unit, where the anaerobic bacteria in the bacterial release box perform denitrification, hydrolysis, acidification, and phosphorus release. Then, the solenoid valve on the drain pipe opens, and the wastewater flows through the drain pipe into the treatment cylinder of the lower unit. There, the aerobic bacteria in the bacterial release box perform COD degradation, nitrification, and phosphorus uptake. The wastewater, after anaerobic and aerobic treatment, is pumped out through the effluent pipe.

[0013] During the wastewater treatment process, the vertical shaft drives the top gears and inner hollow columns of the two treatment mechanisms to rotate through gear transmission. The wastewater is agitated by the lever, and air is ejected from the air outlet of the lower treatment mechanism to replenish oxygen to the wastewater, providing oxygen for the aerobic bacteria in the bacterial release frame of the lower treatment mechanism.

[0014] When it is necessary to observe the state of the microbial community in the release frame, or to operate on the microbial community, manually turn the knob to rotate the lead screw, which in turn moves the internal threaded cylinder away from the connecting sleeve. This, in turn, drives the long rotating rod to rotate through the short rotating rod, which in turn moves the microbial community disc up along the vertical guide column, thereby raising the release frame. At the same time, for observation and operation, the two vertical guide columns can be moved to slide in the arc-shaped groove, which facilitates the observation and operation of the microbial community in the entire release frame.

[0015] Furthermore, the discharge mechanism includes an inlet cylinder and an outlet cylinder fixedly installed on the base plate. The inlet cylinder contains wastewater to be treated, and the inlet cylinder is connected to the treatment cylinder of the upper treatment mechanism through a water inlet pipe. A water pump and a ball valve are installed on the water inlet pipe.

[0016] Furthermore, the processing cylinder of the upper processing mechanism is connected to the processing cylinder of the lower processing mechanism through a drain pipe, and a valve is installed on the drain pipe. The processing cylinder of the lower processing mechanism is connected to the liquid outlet cylinder through a water outlet pipe, and a valve and a water pump are installed on the water outlet pipe. A discharge valve is fixedly installed on the liquid outlet cylinder.

[0017] Furthermore, a detection motor is fixedly installed on the liquid outlet cylinder, a detection cylinder is rotatably installed inside the liquid outlet cylinder, a detector is installed inside the detection cylinder, a discharge hole and an upper notch are provided on the detection cylinder, the detection motor drives the detection cylinder to rotate through gear transmission, and a sealing block is provided inside the liquid outlet cylinder.

[0018] When in use, the wastewater to be treated is put into the inlet cylinder, and the water pump and ball valve on the inlet pipe are turned on. The wastewater in the inlet cylinder enters the treatment cylinder of the treatment mechanism above through the inlet pipe.

[0019] Wastewater in the outlet pipe enters the detection cylinder through the upper notch. At this time, the discharge hole is sealed by the inner wall of the sealing block. The detector then detects the wastewater in the detection cylinder. The detection motor rotates continuously, driving the detection cylinder to rotate through gear transmission. When the detection cylinder rotates 180 degrees, the wastewater in the detection cylinder is detected and discharged from the discharge hole into the liquid outlet cylinder. At this time, the wastewater flowing out of the outlet pipe will not enter the detection cylinder but will directly enter the liquid outlet cylinder. As the upper notch and discharge hole rotate to the side of the sealing block again, the wastewater re-enters the detection cylinder for detection, thus realizing continuous sampling and monitoring of wastewater. Opening the discharge valve can discharge the wastewater in the liquid outlet cylinder.

[0020] When it is necessary to observe the state of the microbial community in the release frame, or to operate on the microbial community, manually turn the knob to rotate the lead screw, which in turn moves the internal threaded cylinder away from the connecting sleeve. This, in turn, drives the long rotating rod to rotate through the short rotating rod, which in turn moves the microbial community disc up along the vertical guide column, thereby raising the release frame. At the same time, for observation and operation, the two vertical guide columns can be moved to slide in the arc-shaped groove, which facilitates the observation and operation of the microbial community in the entire release frame.

[0021] The beneficial effects of this invention compared with the prior art are: (1) This invention combines the anaerobic treatment unit and the aerobic treatment unit in the same frame and bottom plate structure, and connects them in series through pipelines, realizing the high integration of the traditional two-stage biological treatment process. The wastewater completes the core biochemical processes such as anaerobic denitrification, phosphorus release and aerobic nitrification, phosphorus uptake in sequence inside the device. The process flow is smooth and compact, ensuring the continuity of wastewater treatment and the high efficiency and stability of the treatment effect; (2) This invention combines the aeration function with the stirring function. High-pressure air is delivered to the synchronously rotating inner hollow rod through the rotatable inner hollow column and sprayed out from the air outlet on it. Under the action of centrifugal force, the air is thrown out at high speed and broken into fine bubbles, which are evenly dispersed in the wastewater in the treatment cylinder, increasing the gas-liquid contact area and time, solving the problems of easy clogging and uneven air distribution of traditional fixed aeration heads, realizing the efficient mass transfer of oxygen, and creating a superior environment for aerobic bacteria. The oxygen-rich environment significantly improves the efficiency of aerobic biological treatment such as COD degradation and nitrification; (3) By manually rotating the knob and operating the screw transmission mechanism, the bacteria-carrying frame can be smoothly lifted to the liquid surface. At the same time, the bacteria plate can slide along the arc-shaped chute, causing all the bacteria-carrying frames to rotate at a certain angle. This allows the operator to easily observe the growth status of the bacteria and the biofilm without stopping the sewage treatment process or emptying the reactor. It is also easy to perform bacterial supplementation, replacement or sampling operations; (4) The detection cylinder set in this invention rotates periodically under the drive of the motor. The upper notch and the discharge hole alternately cooperate with the sealing block as they rotate, automatically completing the cycle of quantitative sampling, static detection and discharge. This realizes continuous, automatic and intermittent sampling and detection of the treated effluent. Each detection is only for an independent sample, ensuring the accuracy of the detection data.

[0035] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of the present invention, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0036] Example: Figures 1-11As shown, a combined sewage treatment device includes a main body for supplying oxygen to aerobic bacteria. The main body includes a base plate 101, a frame 102 fixedly installed on the base plate 101, and a vertical shaft 104 rotatably installed on the frame 102. The main body is provided with a discharge mechanism for discharging and detecting sewage and two treatment mechanisms for treating sewage with anaerobic bacteria and aerobic bacteria, respectively. The upper treatment mechanism is used for anaerobic treatment of sewage, and the lower treatment mechanism is used for aerobic treatment of sewage. The treatment mechanism includes an inner plate 218 fixedly installed in the base plate 101, an inner hollow column 203 rotatably installed on the inner plate 218, and a treatment cylinder 201 fixedly installed in the base plate 101. The inner hollow column 203 of the lower treatment mechanism has an inner hollow structure and is provided with multiple air inlets 219.

[0037] like Figure 2 , Figure 3 As shown, the main structure includes a top motor 103 fixedly installed on the frame 102. The motor shaft of the top motor 103 is fixedly installed on the vertical shaft 104. A high-pressure air pipe 105 is fixedly installed on the base plate 101. The high-pressure air pipe 105 is connected to an external air unit. A horizontal air pipe 106 is fixedly installed on the high-pressure air pipe 105. The horizontal air pipe 106 has a hollow structure. The hollow column 203 is rotatably installed on the horizontal air pipe 106. Multiple ventilation holes 107 are provided on the high-pressure air pipe 105. The ventilation holes 107 are located in the horizontal air pipe 106. An air inlet 219 is located in the horizontal air pipe 106.

[0038] The top motor 103 drives the vertical shaft 104 to rotate, and high-pressure air is introduced into the high-pressure air pipe 105 through the external air blower. Then the air enters the horizontal air pipe 106 through the vent 107, enters the inner hollow column 203 of the lower processing mechanism through the air inlet 219, and is then ejected through the air outlet 217.

[0039] like Figures 4-8 As shown, the processing mechanism also includes a top gear 202 fixedly installed on the inner hollow column 203. The vertical shaft 104 drives the top gear 202 to rotate through gear transmission. Multiple levers 216 are fixedly installed below the inner hollow column 203. The levers 216 are in contact with the bottom of the processing cylinder 201. An arc-shaped sliding groove 204 is provided on the inner plate 218.

[0040] like Figures 4-8 As shown, the lever 216 of the processing mechanism located below has a hollow structure, and multiple air vents 217 are provided on the lever 216.

[0041] like Figures 4-8As shown, two vertical guide columns 206 are slidably installed inside the arc-shaped chute 204. A connecting rod 205 is fixedly installed on the vertical guide column 206. A microbial community tray 207 is slidably installed on the vertical guide column 206. Multiple microbial placement columns 209 are fixedly installed below the microbial community tray 207. Four layers of microbial placement frames 208 are fixedly installed on the microbial placement columns 209. Several slots are provided on the microbial placement frames 208. Anaerobic bacteria are placed in the microbial placement frames 208 of the upper processing mechanism, and aerobic bacteria are placed in the microbial placement frames 208 of the lower processing mechanism.

[0042] like Figures 4-8 As shown, a long rotating rod 210 is rotatably mounted on the connecting rod 205 and the microbial disk 207, a short rotating rod 211 is rotatably mounted on the long rotating rod 210, an internally threaded cylinder 213 is rotatably mounted on the short rotating rod 211, a connecting sleeve 212 is rotatably mounted on the long rotating rod 210, a lead screw 214 is rotatably mounted inside the connecting sleeve 212, and a knob 215 is fixedly mounted on the lead screw 214. The internally threaded cylinder 213 and the lead screw 214 form a threaded transmission.

[0043] Anaerobic bacteria are placed in the bacterial release frame 208 of the upper treatment unit, while aerobic bacteria are placed in the bacterial release frame 208 of the lower treatment unit. Wastewater first enters the treatment cylinder 201 of the upper treatment unit, where the anaerobic bacteria in the bacterial release frame 208 perform denitrification, hydrolysis, acidification, and phosphorus release. Then, the solenoid valve on the drain pipe 304 opens, and the wastewater enters the treatment cylinder 201 of the lower treatment unit through the drain pipe 304. There, the aerobic bacteria in the bacterial release frame 208 perform COD degradation, nitrification, and phosphorus uptake. The wastewater, after anaerobic and aerobic treatment, is pumped out through the effluent pipe 305.

[0044] During the wastewater treatment process, the vertical shaft 104 drives the top gear 202 and the inner hollow column 203 of the two treatment mechanisms to rotate through gear transmission. The wastewater is stirred by the lever 216, and air is ejected from the air outlet 217 of the lower treatment mechanism to replenish oxygen to the wastewater and provide oxygen for the aerobic bacteria in the bacteria release frame 208 of the lower treatment mechanism.

[0045] When it is necessary to observe the state of the microbial community in the inoculum release frame 208, or to operate on the microbial community, manually turn the knob 215 to drive the lead screw 214 to rotate, thereby driving the internal threaded cylinder 213 to move away from the connecting sleeve 212. This, in turn, drives the long rotating rod 210 to rotate through the short rotating rod 211, thereby driving the microbial community plate 207 to rise along the vertical guide post 206, and thus driving the inoculum release frame 208 to rise. At the same time, for observation and operation, the two vertical guide posts 206 can be moved to slide in the arc-shaped groove 204, which facilitates the observation and operation of the microbial community in the entire inoculum release frame 208.

[0046] like Figures 9-11As shown, the discharge mechanism includes an inlet cylinder 301 and an outlet cylinder 302 fixedly installed on the base plate 101. The inlet cylinder 301 contains sewage to be treated. The inlet cylinder 301 is connected to the treatment cylinder 201 of the upper treatment mechanism through a water inlet pipe 303. A water pump and a ball valve are installed on the water inlet pipe 303.

[0047] like Figures 9-11 As shown, the processing cylinder 201 of the upper processing mechanism is connected to the processing cylinder 201 of the lower processing mechanism through a drain pipe 304. A valve is installed on the drain pipe 304. The processing cylinder 201 of the lower processing mechanism is connected to the liquid outlet cylinder 302 through a water outlet pipe 305. A valve and a water pump are installed on the water outlet pipe 305. A discharge valve 306 is fixedly installed on the liquid outlet cylinder 302.

[0048] like Figures 9-11 As shown, a detection motor 307 is fixedly installed on the liquid outlet cylinder 302, and a detection cylinder 308 is rotatably installed inside the liquid outlet cylinder 302. A detector 309 is installed inside the detection cylinder 308. The detection cylinder 308 is provided with a discharge hole 310 and an upper notch 311. The detection motor 307 drives the detection cylinder 308 to rotate through gear transmission. A sealing block 312 is provided inside the liquid outlet cylinder 302.

[0049] When in use, the wastewater to be treated is placed into the inlet cylinder 301, and the water pump and ball valve on the inlet pipe 303 are turned on. The wastewater in the inlet cylinder 301 enters the treatment cylinder 201 of the upper treatment mechanism through the inlet pipe 303.

[0050] Wastewater in the outlet pipe 305 enters the detection cylinder 308 through the upper notch 311. At this time, the discharge hole 310 is sealed by the inner wall of the sealing block 312. The detector 309 detects the wastewater in the detection cylinder 308. The detection motor 307 rotates continuously, driving the detection cylinder 308 to rotate through gear transmission. When the detection cylinder 308 rotates 180 degrees, the wastewater in the detection cylinder 308 is detected and discharged from the discharge hole 310 into the liquid outlet cylinder 302. At this time, the wastewater flowing out of the outlet pipe 305 will not enter the detection cylinder 308, but will directly enter the liquid outlet cylinder 302. As the upper notch 311 and the discharge hole 310 rotate to the side of the sealing block 312 again, the wastewater re-enters the detection cylinder 308 for detection, so as to realize continuous sampling and monitoring of wastewater. Opening the discharge valve 306 can discharge the wastewater in the liquid outlet cylinder 302.

[0051] The working principle of the combined wastewater treatment device disclosed in this invention is as follows: During use, the wastewater to be treated is placed into the inlet cylinder 301. The water pump and ball valve on the inlet pipe 303 are opened, and the wastewater in the inlet cylinder 301 enters the treatment cylinder 201 of the upper treatment mechanism through the inlet pipe 303. Anaerobic bacteria are placed in the bacterial release frame 208 of the upper treatment mechanism, and aerobic bacteria are placed in the bacterial release frame 208 of the lower treatment mechanism. The wastewater first enters the treatment cylinder 201 of the upper treatment mechanism, where the anaerobic bacteria in the bacterial release frame 208 perform denitrification, hydrolysis, acidification, and phosphorus release. Subsequently, the solenoid valve on the drain pipe 304 is opened, and the wastewater enters the treatment cylinder 201 of the lower treatment mechanism through the drain pipe 304. The aerobic bacteria in the bacterial release frame 208 then perform COD degradation, nitrification, and phosphorus uptake on the wastewater. The wastewater after anaerobic and aerobic treatment is discharged through the water pump on the outlet pipe 305. During the wastewater treatment process, the vertical shaft 104 drives the top gear 202 and the inner hollow column 203 of the two treatment mechanisms to rotate through gear transmission. The wastewater is agitated by the lever 216. The top motor 103 drives the vertical shaft 104 to rotate, and high-pressure air is introduced into the high-pressure air pipe 105 through the external air blower. Then, the air enters the horizontal air pipe 106 through the vent 107, enters the inner hollow column 203 of the lower treatment mechanism through the air inlet 219, and is then sprayed out through the air outlet 217 to supplement oxygen into the wastewater and provide oxygen for the aerobic bacteria in the bacterial release frame 208 of the lower treatment mechanism. Wastewater in the outlet pipe 305 enters the detection cylinder 308 through the upper notch 311. At this time, the discharge hole 310 is sealed by the inner wall of the sealing block 312. The detector 309 detects the wastewater in the detection cylinder 308. The detection motor 307 rotates continuously, driving the detection cylinder 308 to rotate through gear transmission. When the detection cylinder 308 rotates 180 degrees, the wastewater in the detection cylinder 308 is detected and discharged from the discharge hole 310 into the liquid outlet cylinder 302. At this time, the wastewater flowing out of the outlet pipe 305 will not enter the detection cylinder 308, but will directly enter the liquid outlet cylinder 302. As the upper notch 311 and the discharge hole 310 rotate to the side of the sealing block 312 again, the wastewater re-enters the detection cylinder 308 for detection, so as to realize continuous sampling and monitoring of wastewater. Opening the discharge valve 306 can discharge the wastewater in the liquid outlet cylinder 302.

[0052] When it is necessary to observe the state of the microbial community in the inoculum release frame 208, or to operate on the microbial community, manually turn the knob 215 to drive the lead screw 214 to rotate, thereby driving the internal threaded cylinder 213 to move away from the connecting sleeve 212. This, in turn, drives the long rotating rod 210 to rotate through the short rotating rod 211, thereby driving the microbial community plate 207 to rise along the vertical guide post 206, and thus driving the inoculum release frame 208 to rise. At the same time, for observation and operation, the two vertical guide posts 206 can be moved to slide in the arc-shaped groove 204, which facilitates the observation and operation of the microbial community in the entire inoculum release frame 208.

[0053] This invention is not limited to the specific embodiments described above. Any modifications made by those skilled in the art based on the above concept without creative effort are within the protection scope of this invention.
