The invention discloses an ozone catalysis fluidized-bed wastewater treatment apparatus and an application method thereof. The ozone catalysis fluidized-bed wastewater treatment apparatus comprises areactor, an ozone aeration module, a circulating pipeline and a power module; the reactor includes a water-distributing gas-distributing unit, a fluidized-bed filling unit and a drainage unit sequentially from bottom to top; the reactor has a wastewater inlet arranged in the water-distributing gas-distributing unit and a water outlet arranged in the drainage unit; the ozone aeration device is arranged in the water-distributing gas-distributing unit; a first port of the circulating pipeline is connected with the drainage unit, and a second port thereof is connected with the water-distributing gas-distributing unit; the power module is arranged on the circulating pipeline; the inlet end of the power module is communicated with the first port of the circulating pipeline; the outlet end of thepower module is communicated with the second port of the circulating pipeline. The usage of the catalyst herein is reduced; the surface of the catalyst is avoided being contaminated to maximum extent.
Description
technical field [0001] The invention belongs to the technical field of sewage treatment, relates to an ozone catalytic fluidized bed sewage treatment device, and also relates to an application method of the ozone catalytic fluidized bed sewage treatment device. Background technique [0002] At present, the treatment technology of organic matter in sewage in the field of sewage treatment usually includes activated carbon adsorption technology, chemical oxidation technology, ozone oxidation technology, etc. Among them, because the ozone oxidation technology has the advantages of simple process, convenient ozone preparation, flexible operation, and no secondary pollution, it has been paid much attention in the field of sewage treatment, especially in the field of advanced sewage treatment, the removal of refractory organic matter and the improvement of chromaticity plays an important role in removal. [0003] Ozone oxidation technology mainly includes ozone direct oxidation te...
