Innocent treatment method and apparatus for catalytic oxidation of waste water induced by continuous microwave-ultraviolet

Abstract

The invention discloses a wastewater harmless treatment method by continuous microwave-ultraviolet inducing catalysis oxidation and equipment thereof, belonging to the technical field of wastewater treatment process. In the invention, after being pretreated, wastewater flows through an adsorbent reaction bed and carries out microwave-inducing catalysis oxidation reaction, organic matter in wastewater can be quickly decomposed into small molecular inorganic matter and the adsorbent in the reaction bed is recycled by an adsorbent regeneration system; and finally the wastewater is purified and discharged. The invention adopts microwave radiation to improve the adsorption rate of the adsorbent, the regeneration mode of the adsorbent has fast regeneration speed, low energy consumption and no secondary pollution, the continuous process of continuous regeneration and continuous adsorption of the adsorbent can be realized, the batch-type or sequencing-batch-type operation processing mode of the traditional adsorbent can be changed, and the processing capacity of the system can be greatly enhanced.

Description

technical field [0001] The invention discloses a method for harmless treatment of continuous microwave-ultraviolet light induced catalytic oxidation wastewater, and also discloses a special equipment used for harmless treatment of waste water, which belongs to the technical field of waste water treatment technology. Background technique [0002] According to the calculation of the Chinese Academy of Sciences, the current loss caused by environmental pollution and ecological damage has accounted for 15% of the total GDP, which means that environmental problems have already become one of the problems affecting China's sustainable development. Among them, wastewater discharge has become an important factor in environmental pollution. According to relevant reports in the literature: China's average industrial added value of 10,000 yuan requires 330 cubic meters of water consumption and 230 cubic meters of sewage; Discharge of 288,000 tons of waste water, and a large amount of do...

AI Technical Summary

Problems solved by technology

More than 80% of them are directly discharged into rivers without treatment, causing river water pollution.

[0003] The discharge of industrial wastewater is a problem that must be faced in many industries: In the membrane separation system, the permeated water reused by the membrane separation reduces the discharge of water and improves the utilization rate of water, but does not reduce pollutants It only concentrates the pollutants in the water, increases the concentration of pollutants in the concentrated water, saves water but does not reduce pollution, thus limiting the application of membrane separation technology in the field of environmental protection

[0005] 1. Flocculants are used to gather pollutants, resulting in unstable effluent quality;

[0006] 2. The flocculant is a consumable product, which must be continuously added during operation, and cannot be recycled, resulting in high operating costs
