Multifunctional adjustable reactor for catalysis/adsorption regeneration/biodegradation

A catalysis/adsorption regeneration/biodegradation multifunctional adjustable reactor belongs to the technical field of water treatment and comprises a reactor outer shell, a central reaction area shell, a raw water tank, a H2O2 storage box and an ozone generator. According to the invention, multiple functions of ozone and activated carbon are separated, regulated and controlled, functional areas are fully utilized for optimization and integration, the catalytic oxidation capacity, adsorption capacity, synchronous regeneration capacity and biodegradation capacity of the reactor are improved, and multiple functions are organically combined. The reactor adopts an annular structure and a variable cross-section structure to realize proportional regulation and control of adsorption-biodegradation volume and a mixed fluid variable-speed upward flow effect, so that an adsorption filter layer runs in a micro-expansion manner, the water flow resistance is reduced, blockage is prevented, the reaction time for forming a
