AI Technical Summary
Existing Fenton oxidation towers are inefficient in the process of mixing wastewater and reagents, resulting in a longer overall process time and making it impossible to achieve simultaneous feeding and mixing.
An improved Fenton oxidation tower was designed, employing a mixing and guiding component and a water distribution component. Wastewater and reagent solution are simultaneously introduced through the feeding component, and mixed using a mixing plate and a baffle plate. The mixed solution is then discharged through the guiding holes and enters the collection plate, and subsequently evenly distributed into the catalytic stack for reaction through a water distributor.
This technology enables the simultaneous feeding and mixing of wastewater and reagents, saving reaction time and improving overall treatment efficiency.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of Fenton oxidation tower technology, specifically an improved Fenton oxidation tower. Background Technology
[0002] Because some wastewaters contain substances that are difficult to treat biochemically, such as long-chain organic matter in wastewater from the petroleum and coal chemical industries, or effluent from sedimentation tanks after biological treatment, these wastewaters are characterized by low BOD / COD values. To further reduce the COD value, advanced oxidation processes must be used. Among all advanced oxidation processes, the Fenton reagent method is currently one of the most widely used wet catalytic oxidation methods. The Fenton reaction consists of two parts: catalytic oxidation and flocculation.
[0003] Before the Fenton reaction, wastewater and reagents need to be mixed and then introduced into the catalytic packing of the tower through the water distributor. Currently, the mixing work is mainly completed by the stirring mechanism. The stirring work causes the overall process time to be extended, and the mixing work cannot be carried out at the same time as the feeding work, which affects the overall efficiency.

[0006] The aforementioned components achieve the following effects: wastewater and reagent solution can be simultaneously introduced into the mixing and guiding component through the feeding component. The wastewater and reagent solution flow and mix along the mixing and guiding component before entering the collection tray, thus achieving the goal of simultaneous feeding and mixing, saving the overall reaction process time. The solution is then discharged to an external output booster pump group through the outlet pipe. The output booster pump group uses the output booster pump group to output the mixed solution from the water distribution component to the Fenton oxidation tower body, working in conjunction with the catalytic stack to complete the wastewater treatment.
[0007] Preferably, the mixing and guiding assembly includes a mixing disk, a plurality of concentrically arranged baffles are fixed on the bottom inner wall of the mixing disk, and a ring of guiding holes are opened at the bottom of the mixing disk, and the feeding assembly is located at the center of the mixing disk.
[0008] The above components achieve the following effects: the mixing plate can support the wastewater and chemical solution introduced by the feeding component, the baffle can guide and mix the wastewater and chemical solution, and the guide hole can discharge the mixed solution.
[0009] Preferably, the feeding assembly includes a dosing pipe and a liquid inlet pipe, the bottom ends of the dosing pipe and the liquid inlet pipe are connected to a concentrically arranged annular pipe, and the bottom of the annular pipe is connected to an annularly distributed nozzle.
[0010] The above components achieve the following effect: the chemical solution and wastewater can be introduced into the concentrically arranged annular pipe through the dosing pipe and the liquid inlet pipe. The chemical solution and wastewater are simultaneously discharged from the nozzle and complete the initial mixing work when they come into contact with the mixing disc.
[0011] Preferably, a flow guide platform is fixed at the center of the bottom inner wall of the mixing disk, and the flow guide platform is located below the annular tube.
[0012] The effect achieved by the above-mentioned components is that the guide platform can guide the chemical solution and wastewater discharged from the nozzle in all directions, promoting mixing.

[0014] The effect achieved by the above components is as follows: the mixed reagent solution and wastewater can be introduced from the inlet pipe into the spiral coil through the booster pump set, and the mixed solution can be evenly introduced into the reaction catalyst stack in conjunction with the water distributor to carry out the reaction catalysis.
