Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically a wastewater treatment reaction tower. Background Technology

[0002] In the field of wastewater treatment, the reaction tower, as one of the core treatment devices, directly affects the quality and efficiency of wastewater treatment. Traditional reaction tower designs have shortcomings in the mixing and oxidation reaction promotion stages. On the one hand, the design of the mixing device may fail to achieve sufficient mixing of the wastewater, preventing effective contact between pollutants and treatment agents / microorganisms, resulting in incomplete oxidation and failing to achieve the desired treatment effect. On the other hand, in the aeration stage, some reaction towers use inefficient aeration methods, failing to provide the necessary oxygen evenly and sufficiently for the wastewater oxidation reaction. This not only limits the oxidation reaction rate but may also lead to incomplete oxidation in some areas of the wastewater, making it difficult for the treated wastewater to meet discharge standards.

[0003] Meanwhile, traditional aeration methods are not very effective in removing volatile substances from wastewater. Some volatile harmful substances are not effectively discharged and remain in the treated wastewater, posing a potential threat to the environment. Utility Model Content

[0004] The purpose of this invention is to provide a wastewater treatment reaction tower to solve the problems mentioned in the background art.

[0012] Beneficial effects

[0013] Compared with the prior art, the present invention provides a wastewater treatment reaction tower, which has the following beneficial effects:

[0014] 1. The wastewater treatment reaction tower uses a motor to drive the first rotating shaft to rotate, which in turn drives the first stirring rod and the scraper at the bottom to scrape off the impurity particles on the upper surface of the filter screen. This effectively prevents the impurity particles from clogging the filter screen, avoids slowing down the wastewater's entry into the next process, and ensures the smooth flow of the wastewater treatment process.

[0015] 2. In this wastewater treatment reaction tower, the gas generated by the air pump enters the connecting box through the air inlet pipe, then enters the ventilation chamber of the second rotating shaft through the connecting chamber, and is sprayed out from the nozzle to aerate the wastewater, providing sufficient oxygen for the oxidation reaction of the wastewater, while also removing volatile substances, which are then discharged through the air outlet pipe, thereby enhancing the wastewater treatment capacity and efficiency.

Wastewater located below the filter screen 6 is aerated through the spray nozzles 18 to provide oxygen for the oxidation reaction in the wastewater. The second stirring rods 11 promote the mixing and stirring of the wastewater.

[0027] In this embodiment, a liquid inlet channel 2 and an air outlet pipe 4 are provided through the top side of the reaction tower 1, a liquid outlet channel is provided through the bottom of the translation tower 1, and a motor 3 is fixedly installed. An air pump 5 is fixedly installed on the side of the reaction tower 1, and the air outlet pipe 4 is located above the filter screen plate 6.

The connecting box 13 is located below the filter screen plate 6. The first rotating shaft 7 passes through the filter screen plate 6 and extends into the connecting box 13. The first rotating shaft 7 and the second rotating shaft 10 are both movably connected to the connecting box 13.

[0031] In this embodiment, a rotating block 14 is provided in the connecting box 13. The bottom end of the first rotating shaft 7 and the top end of the second rotating shaft 10 are fixedly connected to the rotating block 14.
