Abstract

The invention relates to an ozone catalytic oxidation wastewater treatment device which comprises a pure oxygen source bin, a rotor flow meter, an ozone generator, an electronic flow meter, a pressuresensor and a membrane element reactor which are connected in sequence; a first ball valve and a second ball valve are arranged between the electronic flow meter and the pressure sensor; and a membrane assembly is arranged in the membrane element reactor. The lower part of the membrane element reactor is connected with a wastewater pool through a peristaltic pump, the upper part of the membrane element reactor is provided with a sampling detection port and an ozone degradation outlet, and the ozone degradation outlet is provided with a third ball valve; and the membrane module takes a fluorine-containing hollow fiber membrane as a carrier, and the surface of the membrane module is coated with an ozone catalyst, a cocatalyst, an adsorbent and a blending binder. The device has the advantagesthat the mass transfer efficiency among ozone, pollutants and the catalyst is improved, the ozone utilization rate and the catalytic oxidation reaction rate are increased, the equipment size is effectively reduced, and the investment and operation cost is reduced.

Description

technical field [0001] The invention relates to the technical field of advanced oxidation water treatment equipment, in particular to an ozone catalytic oxidation wastewater treatment device and treatment method. Background technique [0002] my country has long faced the problems of sewage disposal, recycling, and standard discharge from a large number of petrochemical, papermaking, printing and dyeing, coking, and pesticide enterprises. This type of wastewater generally has complex pollutant components, high organic concentration, high salinity components and Difficult to biodegrade and so on. The traditional physicochemical and microbial water treatment processes are only suitable for the treatment of easily degradable organic pollutants, but the treatment methods for refractory organic substances are not mature. [0003] Advanced oxidation technology, as a chemical oxidation water treatment technology, such as Fenton, Fenton-like and micro-electrolysis, is often used to ...
