Abstract

The invention relates to a method for catalytically degrading adsorbed organic pollutants through microwave ultraviolet coupled radiation, belonging to the technical field of pollution control technologies. The invention solves the problems that the consumption level of the traditional adsorbent is high and secondary solid pollutants are produced by using an adsorption method, and overcomes the defects that the microwave-assisted photocatalytic oxidation water treatment and waste gas treatment method is high in energy consumption, easy for generation of thermal pollution and incomplete in degradation of pollutants. In the method, an adsorbent is used to enrich organic matters in waste water and waste gas; a porous wave-adsorbing catalyst for adsorbing the organic matters is placed in a quartz reactor; air with the humidity being 30-100% is introduced into the quartz reactor via an air intake pipe, the microwave ultraviolet reaction time is adjusted to be 10-60 min, and the microwave power is 100-2000 W; and a microwave oven is started, a non-polar ultraviolet lamp is excited by microwaves to generate ultraviolet light, and organic matters are thoroughly mineralized under the combined action of the microwaves, the ultraviolet light and the catalyst. The method is used for treating the organic matters in the waste water and the waste gas.

Description

technical field

[0001] The invention relates to a method for catalytically degrading adsorbed organic pollutants by microwave ultraviolet radiation, and belongs to the technical field of pollution control technology. Background technique

[0002] With the rapid development of the economy, industrial wastewater and petroleum wastewater from papermaking, tanning, petrochemicals, pesticides, pharmaceuticals, dyes, chemical fibers, coking, gas, textile printing and dyeing, food, wood processing, etc. are increasing, and its pollution level and health impact Gaining importance. Among them, industrial wastewater contains many types of organic matter, a high proportion of synthetics, many organic poisons, and is not easy to biodegrade. The main pollutants in petroleum wastewater are various hydrocarbons—alkanes, naphthenes and aromatic hydrocarbons, among which polycyclic aromatic hydrocarbons are carcinogenic.

[0003] Organic waste gas mainly comes from waste gas emitted during...
