The fluidized bed Fenton system is an advanced oxidation technology used for treating refractory organic wastewater.

Its main equipment components typically include the following parts:

1. Reactor: This is the core part of the entire system, used for carrying out chemical reactions. The design of the fluidized bed Fenton reactor ensures that the Fenton reagent can fully contact and react with organic matter in the wastewater.

2. Dosing device: Responsible for adding necessary chemical agents into the reactor to maintain appropriate chemical conditions that promote the occurrence of the Fenton reaction.

3. Air distribution plate/nozzle: Located at the bottom of the reactor, it introduces gas (usually air) into the system to keep solid particles suspended, forming the so-called "fluidized bed," thereby increasing the contact opportunities between pollutants and oxidants.

4. Agitation device: In some designs, agitators may be used to promote uniform mixing, ensuring full contact between reactants.

5. Solid-liquid separation device: The treated wastewater needs to undergo solid-liquid separation to remove sediments or residual catalysts generated during the reaction, ensuring that the effluent quality meets standards.

6. pH adjustment device: Since the Fenton reaction alters the acidity and alkalinity of the solution, a pH adjustment device may be necessary to control the pH value during the reaction process, optimizing reaction efficiency.

7. Control system: Integrates automated control functions to monitor and regulate operational parameters of each unit, such as temperature, pressure, and flow rate, ensuring stable system operation and treatment effectiveness.

These components work together to enable the fluidized bed Fenton system to efficiently remove organic pollutants from water while also effectively controlling operational costs and environmental impact.
