DETAILED DESCRIPTION

[0018] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0019] The utility model provides Figure 1-Figure 2 An industrial wastewater treatment system shown includes a housing 1 and a regulating tank 4. A compressed air system 2 is provided in the housing 1. An air storage tank 3 is provided in the housing 1. The compressed air system 2 and the air storage tank 3 are connected by a pipeline. An air guide pipe 5 is connected to the air storage tank 3. The other end of the air guide pipe 5 is connected to the regulating tank 4. An air compressor 6 is installed on the air guide pipe 5. A distributor 7 is provided in the regulating tank 4. The air inlet end of the distributor 7 is interconnected with the air guide pipe 5. Jet ports 8 are provided on both sides of the distributor 7. There are multiple jet ports 8, and the jet ports 8 are arranged in an array on the distributor 7. A water inlet pipe 9 is fixedly installed on the top of the housing 1, and the water inlet pipe 9 is interconnected with the regulating tank 4.

[0020] Before wastewater is injected into the regulating tank 4 through the water inlet pipe 9, the redundant compressed air in the compressed air system 2 is stored in the air tank 3. After wastewater is injected into the regulating tank 4, the air tank 3 is opened, and the compressed air inside the air tank 3 passes through the air guide pipe 5 and the air compressor 6. The air compressor 6 introduces the pressurized air into the distributor 7 inside the regulating tank 4. Since there are many jet ports 8 on the distributor 7, air is ejected at high speed through the jet ports 8 to form a jet, which has an impact and suction effect on the surrounding liquid, causing the liquid to flow and mix. The movement of bubbles and jets causes turbulence in the liquid, increases the collision and diffusion between liquid molecules, and helps to evenly distribute the substances. At the same time, the compressed air increases the dissolved oxygen content in the water, which helps to prevent anaerobic reactions in the wastewater in the regulating tank and the production of odorous gases and harmful substances, thereby improving the compressed air utilization rate of the compressed air system 2 and reducing energy consumption.

[0021] A filter grille 13 is fixedly installed at the entrance of the regulating tank 4, a waterproof shell 10 and a collection box 15 are installed on the outside of the regulating tank 4, a linear motor 11 is fixedly installed inside the waterproof shell 10, the output end of the linear motor 11 is set through the regulating tank 4, a cleaning plate 12 is fixedly installed on the output end of the linear motor 11, and the cleaning plate 12 is slidably set on the filter grille 13. A through hole is provided on one side of the regulating tank 4 near the filter grille 13, and the through hole is connected to the collection box 15. A movable baffle 14 is rotatably installed at the through hole position on the regulating tank 4;

[0022] When wastewater is injected into the regulating tank 4, the wastewater enters the regulating tank 4 through the filter grille 13. The filter grille 13 is set to filter out larger suspended matter such as branches and plastic sheets to prevent larger suspended matter such as branches and plastic sheets from clogging subsequent processing equipment. When the wastewater is injected, the linear motor 11 is started, and the linear motor 11 drives the cleaning plate 12 to move back and forth on the filter grille 13. When the cleaning plate 12 moves to the opening position on the regulating tank 4, the cleaning plate 12 pushes the movable baffle 14 to rotate, thereby pushing larger suspended matter such as branches and plastic sheets into the collection box 15, thereby realizing unified collection and processing of larger suspended matter such as branches and plastic sheets, and facilitating centralized processing.

[0023] A water pipe 20 is connected to the regulating tank 4 near the bottom. A water pump 21 is installed on the water pipe 20. The other end of the water pipe 20 is connected to the flocculant addition pipe 19.

[0024] After the wastewater is treated in the regulating tank 4, it is injected into the flocculant addition pipe 19 through the water pump 21 and the water pipe 20 to facilitate the next step of treatment.

[0025] A flocculant addition pipe 19 is provided through the housing 1. The bottom of the flocculant addition pipe 19 is connected to a flocculation tank 16. The flocculation tank 16 is provided inside the housing 1. A motor 17 is fixedly installed on the top of the housing 1. A stirring rod 18 is fixedly installed on the output end of the motor 17. The stirring rod 18 is provided inside the flocculation tank 16.

[0026] After the wastewater treated in the regulating tank 4 is injected into the flocculation tank 16, in order to make the fine suspended matter and colloidal particles in the wastewater condense into larger flocs, thereby accelerating the sedimentation speed and improving the efficiency of solid-liquid separation, it is necessary to add flocculants for treatment. The flocculant is injected into the flocculation tank 16 through the flocculant addition pipe 19, and then the motor 17 is started. The motor 17 drives the stirring rod 18 to rotate in the flocculation tank 16. After rapid stirring and slow stirring, the heavy metal ions and organic matter in the wastewater are adsorbed to form flocs under the action of the flocculant, which is convenient for the subsequent precipitation treatment.

[0027] The flocculation tank 16 is connected to a delivery pipe 28, the other end of which is connected to a sedimentation tank 24. The sedimentation tank 24 is disposed in the housing 1. A water pump 22 is installed on the delivery pipe 28, and an activated carbon filter 23 is installed on the delivery pipe 28.

[0028] After the wastewater is flocculated, it is transported to the sedimentation tank 24 through the water pump 22 and the delivery pipe 28. During this process, the wastewater will pass through the activated carbon filter 23. Because some flocculants themselves may be toxic or difficult to degrade, if they are used improperly or not treated thoroughly, they may remain in the wastewater. The activated carbon filter 23 is set to adsorb and intercept the residual flocculant particles to avoid secondary pollution to the environment.

[0029] An outlet pipe 26 is installed on the sedimentation tank 24, one end of which extends to the outside of the shell 1. A water pump 27 is installed on the outlet pipe 26. A discharge port 25 is fixedly installed at the bottom of the sedimentation tank 24, and the discharge port 25 is installed on the shell 1.

[0030] After the wastewater in the sedimentation tank 24 has settled for a period of time, the water pump 3 27 is turned on, and the water pump 3 27 discharges the supernatant from the sedimentation tank 24 through the outlet pipe 26. After the supernatant is discharged, the discharge port 25 is opened, and the sediment at the bottom of the sedimentation tank 24 flows out of the sedimentation tank 24 through the discharge port 25, thereby achieving the purification of the wastewater.

[0031] The working principle of the present invention is as follows: before wastewater is injected into the regulating tank 4 through the water inlet pipe 9, the redundant compressed air in the compressed air system 2 is stored in the air tank 3. After the wastewater is injected into the regulating tank 4, the air tank 3 is opened, and the compressed air inside the air tank 3 passes through the air guide pipe 5 and the air compressor 6. The air compressor 6 introduces the pressurized air into the distributor 7 inside the regulating tank 4. Since there are many jet ports 8 on the distributor 7, the air is ejected at high speed through the jet ports 8 to form a jet, which has an impact and suction effect on the surrounding liquid, causing the liquid to flow and mix. The movement of bubbles and jets causes turbulence in the liquid, increases the collision and diffusion between liquid molecules, and helps to evenly distribute the substance. At the same time, the compressed air increases the dissolved oxygen content in the water, which helps to prevent the wastewater from undergoing anaerobic reactions in the regulating tank and producing odorous gases and harmful substances, thereby improving the compressed air utilization rate of the compressed air system 2 and reducing energy consumption.

[0032] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions merely illustrate the principles of the present invention. Various changes and improvements are possible without departing from the spirit and scope of the present invention.
