Abstract

The invention discloses a system for treating refractory organic matters by combining microwave catalysis with advanced oxidation. Refractory organic matters to be treated sequentially enter a feedingunit, a microwave catalysis unit, an advanced oxidation unit and a water outlet unit to be treated and are discharged when the refractory organic matters reach the standard. The system for treating refractory organic matters by combining microwave catalysis with advanced oxidation comprises a first oxidative degradation treatment unit and a second oxidative degradation treatment unit, wherein thefirst oxidative degradation treatment unit integrates microwave radiation, catalysis and oxidation, and the second oxidative degradation treatment unit adopts advanced oxidation of ozone oxidation. The degradation treatment efficiency of refractory organic matters in industrial pollutants is improved, and the problems of low treatment efficiency, low reaction rate, strict reaction conditions andthe like in the prior art are solved. A catalyst is recovered and recycled, so that the environmental pollution caused by the discharge of the catalyst is avoided. The treatment method disclosed by the invention is simple to operate, high in engineering applicability, thorough in oxidative degradation of refractory organic pollutants and free of secondary pollution.

Description

technical field [0001] The invention relates to the technical field of organic wastewater treatment, in particular to a system for microwave catalysis combined with advanced oxidation to treat refractory organic matter. Background technique [0002] The total discharge of industrial wastewater in my country has been declining for four consecutive years, but the base of the amount of wastewater in my country is still large, and the efficiency of wastewater treatment is low. Improving the efficiency of industrial wastewater treatment has become an urgent problem to be solved in the field of industrial wastewater. [0003] The main pollutants in industrial wastewater are refractory organic substances, which are mainly produced by petrochemical, papermaking, dyestuff and other chemical production. Seriously endanger human health and affect the ecological environment. Therefore, the degradation treatment of refractory organic matter is directly related to the healthy and sustain...
