Description

Technical Field

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

[0002] Chinese patent document CN210393923U discloses a chemical wastewater treatment device, comprising an aeration tank body with an inlet and an outlet. A main air inlet pipe is located at the bottom of the aeration tank body, connected to an external air pump. One or more branch air outlet pipes are connected to the main air inlet pipe, with their openings facing upwards. Each branch air outlet pipe contains a cleaner, with each cleaner corresponding to a branch air outlet. A first support is connected to the upper part of the cleaner, and a lifting component is connected to the upper part of the first support. The lifting component is connected to a second support, and a lifting device is connected to the top of the second support. This invention effectively prevents aeration pipe blockage and effectively cleans the aeration pipes without requiring manual cleaning, saving time and effort. Furthermore, it purifies the waste gas discharged from the aeration tank, protecting the surrounding environment.

[0003] After investigation and analysis, the patent has the following drawbacks in actual use: The aeration system of this device usually relies on the direct release of air bubbles through aeration pipes, lacking an effective water flow disturbance mechanism. The water body is prone to forming a fixed flow path, resulting in obvious dead zones and local stagnant areas in the pool, which leads to insufficient aeration efficiency.

[0004] In summary, this application proposes a chemical wastewater treatment device to solve the aforementioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a chemical wastewater treatment device that can solve the problem that aeration systems usually rely on aeration pipes to directly release air bubbles, lack an effective water flow disturbance mechanism, and the water body is prone to forming a fixed flow path, resulting in obvious dead zones and local stagnant areas in the pool, which leads to insufficient aeration efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a chemical wastewater treatment device, comprising: An aeration tank is equipped with aeration pipes inside, and a purification box is fixedly installed on the top of the aeration tank. A mixing component is installed on an aeration tank. The mixing component includes stirring blades and a rotating column.

The auxiliary components include activated carbon plates, connecting plates, crossbars, elastic plates, and locking rods. Activated carbon plates are installed inside the purification box. A connecting plate is fixedly installed on one side of the activated carbon plates. Two sets of elastic plates are slidably installed on the crossbars and are symmetrically distributed front and back. Locking rods are fixedly installed on the front side of the elastic plates. Locking slots are opened on both the front and back sides of the purification box. The other end of the locking rod passes through the connecting plate and is locked into the locking slot.

A backwash pipe is fixedly installed at the output end of the high-pressure water pump. The other end of the backwash pipe passes through the aeration tank and is fixedly installed on the outer wall of the aeration pipe. The other end of the sewage outlet pipe extends to the outside of the aeration tank. Aeration can introduce oxygen into the wastewater, promote the degradation of organic matter in the water, and the high-pressure water flow backwashing can remove impurities and accumulated substances in the aeration pipe, prevent equipment blockage and failure, improve the operational reliability of the equipment, and extend the service life of the equipment.

The activated carbon plate has good adsorption performance and can effectively remove harmful gases emitted during wastewater treatment. It can significantly reduce the concentration of harmful gases in the air, improve environmental quality, and avoid directly releasing untreated waste gas into the air, ensuring that the emitted gas is cleaner and meets environmental protection standards. Through the disassembly function, the activated carbon plate can be easily removed and replaced. The activated carbon plate can be replaced or regenerated regularly as needed to ensure that the purification effect always reaches the best state.

At the same time, through the action of stirring blades, the rising path of bubbles in the pool is disturbed, which prolongs the residence time of bubbles, thereby increasing the contact time between oxygen and pollutants in the water, improving the oxygen dissolution efficiency, and thus improving the aeration effect.

[0014] (2) This chemical wastewater treatment equipment uses activated carbon plates, connecting plates, crossbars, fixing blocks, elastic plates, clamps and springs in combination.

The other end of the backwash pipe 4 passes through the aeration tank 1 and is fixedly installed on the outer wall of the aeration pipe 2. The other end of the sewage outlet pipe 6 extends to the outside of the aeration tank 1. Aeration can introduce oxygen into the wastewater, promote the degradation of organic matter in the water, and remove impurities and accumulated substances in the aeration pipe through high-pressure water backwashing, prevent equipment blockage and failure, improve the operational reliability of the equipment, and extend the service life of the equipment.

[0020] Furthermore, the mixing assembly also includes a motor 7. The motor 7 is fixedly installed on one outer wall of the aeration tank 1.

The stirring blade 8 can break the dead corners and local stagnant areas of the water flow, promote the uniform distribution of the water flow, and make the bubbles more evenly distributed in the water body, thereby increasing the contact time between the wastewater and the bubbles. At the same time, through the action of the stirring blade 8, the rising path of the bubbles in the tank is disturbed, which prolongs the residence time of the bubbles, thereby increasing the contact time between oxygen and pollutants in the water, improving the oxygen dissolution efficiency, and thus improving the aeration effect.

[0021] Furthermore, the auxiliary components also include a fixing block 13 and springs 16. The crossbar 12 is fixedly installed on the inner wall of the connecting plate 11.

The activated carbon plate 10 has good adsorption performance and can effectively remove harmful gases emitted during wastewater treatment. It can significantly reduce the concentration of harmful gases in the air, improve environmental quality, and avoid the direct release of untreated waste gas into the air, ensuring that the emitted gas is cleaner and meets environmental protection standards.

[0025] Working Principle: During operation, the filtered wastewater (after being filtered through quartz sand and activated carbon to remove suspended solids) enters the aeration tank 1 through the inlet pipe 17. By starting the external blower, the aeration pipe 2 releases fine bubbles into the tank. As the bubbles rise, they thoroughly mix with the wastewater. A dissolved oxygen sensor monitors the oxygen content in the water in real time. Simultaneously, the motor 7 is started, driving the stirring blades 8 on the rotating column 18 to rotate, thus agitating the wastewater and ensuring that all wastewater comes into contact with oxygen. When it is necessary to adjust the aeration pipe 2... During cleaning, close the valve on the air inlet pipe 3 and open the valves on the backwash pipe 4 and the drain pipe 6. The high-pressure water pump 5 will pump high-pressure water into the aeration pipe 2 through the backwash pipe 4. The water flow will flow along the aeration pipe 2, dispersing the impurities and biofilm attached to the inner wall of the aeration pipe 2. Then, the water carrying the impurities will be discharged through the drain pipe 6, thus achieving the backwashing function. When cleaning or replacing the activated carbon plate 10, move the pull rod outward so that the pull rod drives the locking rod 15 on the elastic plate 14 away from the locking groove, and the activated carbon plate 10 can be disassembled.
