Abstract

The invention discloses an ozone catalytic fluidized bed device for treating high-concentration organic wastewater difficult to biodegrade, and relates to sewage treatment technology in the field of environmental protection. The ozone catalytic fluidized bed device structurally comprises an organic wastewater conveying pipeline and a dissolved air water conveying pipeline which are used for beingconnected with a sewage storage tank, a sewage pressure pump, an ozone generation device, a dissolved air pump, a fluidized bed reactor and a plurality of control valves, a top dissolved air water distribution pipe is arranged at the top of the fluidized bed reactor and is communicated with a dissolved air water distribution head to convey dissolved air water; the invention also discloses a methodfor organic wastewater treatment. The method comprises the following steps: adding the organic wastewater into the sewage storage tank, starting the ozone generation device, and filling a catalyst atthe bottom of the fluidized bed reactor; at least one part of ozone generated by the ozone generation device is mixed with the organic wastewater and then is conveyed to the dissolved air pump to generate dissolved air water; gas-dissolved water enters the bottom of the fluidized bed reactor through a pipeline from the top gas-dissolved water distribution pipe to the gas-dissolved water distribution head and is in contact with the granular catalyst to generate a catalytic degradation reaction.

Description

technical field [0001] The invention relates to the field of ecological environment protection sewage treatment, especially advanced oxidation equipment and treatment methods in the field of high-concentration refractory biodegradable industrial sewage treatment equipment, in particular to an ozone catalytic flow for the treatment of high-concentration refractory biodegradable organic wastewater Chemical bed apparatus and treatment method.
