Description

Technical Field

[0001] This invention relates to the field of wastewater treatment; specifically, it relates to an intelligent control system for an integrated spore transfer machine. Background Technology

[0002] Spore transfer technology relies on fine nano-sized spores to form a water-air-solid three-phase mixture with hydrophobic suspended matter in wastewater. This three-phase mixture has an apparent density less than that of water and floats to the surface due to physical properties. It is then automatically scraped off by a sludge scraper, thereby achieving water purification. Spore transfer technology mainly treats hydrophobic suspended matter and destabilized colloidal particles. Through coagulation and chemical dosing, total phosphorus pollutants and some COD and SS pollutants in the water are removed by forming flocs from hydrophobic impurities and floating to the surface. Spore transfer technology is an ultra-limit phosphorus removal technology, with a total phosphorus removal rate of 70% to 90%, and an effluent total phosphorus concentration of 0.02 to 0.05 mg / L. It is mainly used for end-of-pipe phosphorus removal from domestic sewage and industrial wastewater, phosphorus removal from slightly polluted water bodies, and reoxygenation, phosphorus removal, and algae reduction in rivers, lakes, or landscape water bodies. Utility model patent CN217947867U discloses a precision filtration spore transfer integrated machine, which removes pollutants from sewage by transferring spores through the setting of baffles, guide plates, separation baffles, filter baffles, spore contact zones, spore separation zones, precision filtration zones, filtered water collection zones, and ultraviolet disinfection zones. Utility model patent CN217947843U discloses a vertical flow spore transfer integrated machine, which removes pollutants from sewage by setting up coagulation zones, contact zones, and separation zones. To avoid excessive downward flow velocity affecting sludge-water separation, the effluent level is controlled below the scum layer, ensuring separation effectiveness from multiple angles. However, existing technologies typically require an air-explosion device to introduce spores generated by the spore reactor into the decontamination machine in the form of micro-nano bubbles. This air-explosion device causes the wastewater and micro-nano spores to mix and flow rapidly upwards. This can result in insufficient reaction time, causing the spores to be swept to the top of the decontamination machine and detached from the lower part where the micro-nano spore concentration is higher. Consequently, the spores do not have enough time to react with the hydrophobic suspended solids in the wastewater, failing to form a water-air-solid three-phase mixture and thus failing to thoroughly decontaminate the wastewater.

[0003] (a) Technical problems to be solved

[0004] To address the aforementioned technical problems, this invention provides an intelligent control system for an integrated spore transfer machine.

[0005] (II) Technical Solution

[0006] An intelligent control system for an integrated spore transfer machine includes a wastewater spore concentration detection system, a spore generation device, a spore output system, a three-phase reaction time recording system, a spore output control system, a wastewater detection system, a decontamination device, a reaction comparison system, an automatic impurity scraping device, and a decontamination control system. The wastewater spore concentration detection system detects the concentration of total phosphorus pollutants and some COD and SS pollutants in the wastewater to be decontaminated, determines the specific pollutant concentration, determines the required amount of micro / nano spores based on the specific pollutant concentration, and transmits the required number of micro / nano spores to the spore generation system. The spore generation system generates a specific number of spores according to the required amount, which are then output by the spore output system.

[0007] Furthermore, the spore output system is connected to the spore output control system. The spore output control system controls the opening and closing of the specific spore output system. The spore output system includes a spore output tube, which transmits the spores to the lower end of the decontamination device. At the lower end of the decontamination device, multiple air-explosion inlet pipes are connected to the spore output tube, and the multiple air-explosion inlet pipes are connected to the interior of the decontamination device.

[0008] Furthermore, the decontamination device includes a decontamination tank, a three-phase reaction tank, a countercurrent zone, and a dirt removal zone; an automatic dirt scraping device is installed in the dirt removal zone; the bottom of the decontamination tank is provided with multiple connecting holes for the gas explosion inlet pipe and connected to the gas explosion inlet pipe; a sewage tank is provided outside the decontamination tank; the sewage tank is connected to a sewage output pipe; a sewage valve is installed on the sewage output pipe; and sewage is introduced into the three-phase reaction tank of the decontamination tank through the sewage valve.

[0009] Furthermore, the three-phase reaction tank is located at the bottom of the decontamination tank. Inside the three-phase reaction tank, there are partitions I and II, which intersect each other, dividing the interior of the three-phase reaction tank into three-phase reaction zone I, three-phase reaction zone II, three-phase reaction zone III, and three-phase reaction zone IV. Each three-phase reaction zone is provided with side walls, a bottom wall, and an upper wall.

[0010] Furthermore, one side wall of the three-phase reaction zone I is the outer wall of the three-phase reaction tank, and a sewage outlet pipe is provided on its outer wall. Sewage enters the three-phase reaction zone I through the sewage outlet pipe. The bottom end of the three-phase reaction zone I is connected to the gas explosion inlet pipe I. The side wall separating the three-phase reaction zone I and the three-phase reaction zone IV is part of the partition I. The side wall separating the three-phase reaction zone I and the three-phase reaction zone II is part of the partition II. A valve is provided on the side wall separating the three-phase reaction zone I and the three-phase reaction zone II.

[0011] Furthermore, the sidewall separating the three-phase reaction zone II and the three-phase reaction zone III is another part of the partition I. A valve is installed on the sidewall separating the three-phase reaction zone II and the three-phase reaction zone III. The bottom end of the three-phase reaction zone II is connected to the gas explosion inlet pipe II.

[0012] Furthermore, the sidewall separating the three-phase reaction zone III and the three-phase reaction zone IV is another part of the partition II. A valve is installed on the sidewall separating the three-phase reaction zone III and the three-phase reaction zone IV. The bottom end of the three-phase reaction zone III is connected to the gas explosion inlet pipe III.

[0013] Furthermore, the other side wall of the three-phase reaction zone IV is the outer wall of the decontamination tank, and a clean water outlet is provided on this side wall. The bottom of the three-phase reaction zone IV is connected to the gas explosion inlet pipe IV, and the clean water outlet circulates the decontaminated water into the decontamination tank.

[0014] Furthermore, the upper walls of the three-phase reaction zones I-IV are all the upper walls of the decontamination tank, and multiple flow holes are provided on the upper walls.

[0015] Furthermore, a baffle plate is installed at the upper end of the three-phase reaction tank in the cleaning tank. The baffle plate is inclined. An air jet device is installed on the side wall of the cleaning tank corresponding to the position of the baffle plate. The air jet device sprays air onto the baffle plate and sprays it downwards towards the three-phase reaction tank due to the action of the inclined baffle plate. The baffle plate is provided with multiple flow holes. The baffle plate is hinged to one side of the cleaning tank, and a countercurrent area is formed between the baffle plate and the three-phase reaction tank.

[0016] Furthermore, an automatic impurity scraping device is provided at the upper end of the decontamination tank. The automatic impurity scraping device includes an impurity removal cover, an impurity removal track is provided on the impurity removal cover, the length of the impurity removal track is the same as that of the impurity removal cover, and a track car is provided inside the impurity removal track. The track car drives the impurity removal roller to move on the impurity removal cover.

[0017] Furthermore, the three-phase reaction time recording system records the decontamination reaction time for polluted water with different pollutant concentrations and corresponding numbers of micro / nano spores, and defines this standard reaction time as T0. Wastewater with a determined pollutant concentration is then introduced into the three-phase reaction zone I of the decontamination tank. Simultaneously, the valves on the side walls between three-phase reaction zones I and II, as well as the valve between three-phase reaction zones II and III, are opened. The opening and closing of each valve is controlled by the decontamination control device to ensure the flow rate and volume of wastewater between the three reaction zones. At the same time, the valve on the side wall between three-phase reaction zones III and IV is closed, allowing the wastewater to remain in three-phase reaction zones I-III.

[0018] Furthermore, the purity of the wastewater in the three reaction zones was tested. Once the purity of the water was found to be up to standard, the valve on the side wall between the three-phase reaction zone III and the three-phase reaction zone IV was opened to allow the pure water to flow out.

[0019] Furthermore, while the wastewater is being decontaminated in the three reaction zones, the reacted three-phase mixture enters the countercurrent zone through the flow hole at the top of the decontamination tank. At this time, the jetting device is turned on so that the gas is sprayed onto the inclined baffle plate, forming a downward countercurrent in the countercurrent zone that counteracts the upward water flow and the three-phase mixture, causing the generated three-phase mixture and wastewater to flow back into the decontamination tank for repeated decontamination.

[0020] Furthermore, the time T1 for achieving the decontamination standard and the standard reaction time T0 are compared in the reaction comparison system. If T1 <= T0, the current amount of micro-nano spores introduced into the gas explosion inlet pipes I-III remains unchanged, and the valves can be adjusted to accelerate the flow rate of sewage between the three-phase reaction zones I-III. If T1 > T0, the amount of micro-nano spores introduced into the gas explosion inlet pipe I is increased, and the valves are adjusted to slow down the flow rate of sewage between the three-phase reaction zones I-III.

[0021] Furthermore, after the decontamination is completed, the baffle plate hinged to the decontamination tank is driven to flip by the drive device, and the jetting device stops jetting, so that the three-phase mixture floats upward to the automatic impurity scraping device for removal.

[0022] (III) Beneficial Effects

[0023] This invention utilizes multiple air-explosion inlet devices to allow micro-nano spores to enter the decontamination tank and react with wastewater to form a water-air-solid three-phase mixture for pollutant removal. Control and detection devices are used to determine the relationship between specific wastewater pollutant content and spore quantity to prevent waste of micro-nano spores. The three-phase reaction tank and counter-current zone allow wastewater to remain in the bottom reaction area for an extended period. Detection devices and comparisons with standard reaction times precisely control the amount of micro-nano spores introduced and the reaction time between wastewater and spores, preventing unreacted wastewater from moving upwards under the aeration device and failing to completely remove pollutants.

The upper walls of the three-phase reaction zones I-IV are all the upper walls of the decontamination tank. Multiple flow holes are installed on the upper walls. A baffle plate (7) is installed at the upper end of the three-phase reaction tank in the decontamination tank. The baffle plate (7) is inclined. A jetting device is installed on the side wall of the sludge tank (1) at the position corresponding to the baffle plate. The jetting device (6) sprays air onto the baffle plate (7).

At the same time, the valve on the side wall between three-phase reaction zones III and IV was closed, allowing the wastewater to remain in three-phase reaction zones I-III. The purity of the wastewater in the three reaction zones was tested. Once the water purity met the standard, three-phase reaction zones III and IV were opened. The valves on the side walls allow pure water to flow out. When the wastewater is being decontaminated in the three reaction zones, the reacted three-phase mixture will enter the countercurrent zone through the flow hole at the top of the decontamination tank. At this time, the jet device is turned on so that the gas is sprayed onto the inclined baffle plate, forming a downward countercurrent in the countercurrent zone, which counteracts the upward water flow and the three-phase mixture. This causes the generated three-phase mixture and wastewater to flow back into the decontamination tank for repeated decontamination.

If T1 <= T0, the current amount of micro-nano spores introduced into the gas explosion inlet pipes I-III remains unchanged, and the valves can be adjusted to accelerate the flow rate of wastewater between the three-phase reaction zones I-III.If T1 > T0, increase the amount of micro / nano spores introduced into pipe I via atmospheric explosion, and adjust the valve to slow the flow rate of wastewater between the three-phase reaction zones I and III. After decontamination is completed, the baffle plate hinged to the decontamination tank is driven to flip by the drive device, and the jetting device stops jetting, causing the three-phase mixture to float upwards to the automatic impurity scraping device for removal.
