Method and equipment for processing chemicals waste water by catalytic oxidation of activated carbon induced by microwaves

Abstract

The invention discloses a method for processing chemicals waste water by catalytic oxidation of activated carbon induced by microwaves, comprising the following steps: firstly, the waste water and air enters an activated carbon reaction bed, and the reaction of inducing the catalytic oxidation of the activated carbon by the microwaves is conducted in the activated carbon reaction bed; and secondly, water discharged from the activated carbon reaction bed is subjected to gas-liquid separation after being condensed, separated liquid is emitted when reaching the standard, and separated gas is emitted by reaching the standard by being processed by adsorption. The invention also discloses equipment adopting the method. The method for inducing the catalytic oxidation of the activated carbon by the microwaves has a plurality of advantages as follows: the degradation rate is high, the processing time is short, the degradation is conducted under normal pressure, the requirements on equipment material is low, the investment cost on a system one time is small, and the like. Simultaneously, as microwave technology is adopted for processing sewage, a sewage processing project can be miniaturized and decentralized, and drain contamination pipe networks can be reduced, so that the water environment of humanity can realize virtuous circle, and higher economic benefits can be realized.

Description

technical field [0001] The invention belongs to the field of water treatment, in particular to a method and equipment for microwave-induced activated carbon catalytic oxidation treatment of chemical wastewater. Background technique [0002] With the rapid development of my country's water transport industry, the cargo volume and variety of chemicals continue to increase. The transportation mode of liquid chemicals is mainly in bulk, and the waste water from port tank washing comes from the ballast water and water produced during the loading and unloading of cargo ships. Tank washing water. The wastewater not only contains chemicals that are difficult to treat biologically, such as toluene, phenol, formaldehyde, styrene, acrylonitrile, and cleaning agents used to clean the cabin, but also because of the intermittent operation of the bulk chemical port and the variety of pollutants. The water quality and quantity are variable and random, and it is difficult to deal with them....

AI Technical Summary

Problems solved by technology

However, tank washing wastewater contains residual chemicals in the tank and cleaning agents used, and its water quality often varies with the types of chemicals transported, and the biochemical properties vary greatly, which has high requirements for the adaptability of the biological treatment system; In addition, due to the intermittent operation of chemical ports, the variability and randomness of wastewater volume and water quality will inevitably destroy the stable operation of the biochemical treatment system to varying degrees.
