Enhanced oxidization device and method used for organic wastewater treatment

Abstract

The invention relates to an enhanced oxidization device and method used for organic wastewater treatment. The device comprises a shell, wherein a rotary drum is arranged in the inner cavity of the shell, a cylindrical rotary filler is arranged in the rotary drum, a liquid distributor is arranged at the central position of the inner cavity of the shell and is disposed in the inner ring of the rotary filler with a gap from the inner ring of the rotary filler, the lower part of the rotary drum is provided with a rotary shaft, the rotary shaft is concentrically connected with the rotary drum, and the lower end of the rotary shaft runs through the shell and is connected with a rotary power mechanism. The device disclosed by the invention is provided with two structural forms consisting of gas-liquid contact and liquid-liquid contact. The enhanced oxidization equipment disclosed by the invention provides strong centrifuge power under high-speed rotation condition, and the liquid materials are torn to be fine liquid drips, liquid films and liquid wires under the action of the centrifuge power, thus the gas liquid reaction mass-transfer efficiency is higher and the oxidant and the organic waste water can be mixed more evenly.

Description

Technical field [0001] The invention relates to an intensified oxidation device and a method thereof, in particular to an intensified oxidation device and method for organic wastewater treatment, which has short oxidation reaction time, uniform mixing, and convenient operation and maintenance. Background technique [0002] With the rapid development of industry, a large amount of organic wastewater is produced. For example, the organic wastewater produced in petrochemical, coking, paper, pharmaceutical, plastic, dyestuff industries has one thing in common in water quality, that is, high organic content and difficult to biodegrade, collectively referred to as high-concentration non-biodegradable wastewater. This type of wastewater is difficult to treat, and it is usually pretreated by chemical oxidation, coagulation and other processes before biological treatment. The purpose of chemical oxidation is to remove organic matter and improve the biodegradability of wastewater. Common...

AI Technical Summary

Problems solved by technology

Commonly used oxidants include ozone, hydrogen peroxide, persulfate, supercritical water, electrochemistry, etc. Although these oxidation processes have good treatment effects, they also have some problems, such as low two-phase mass transfer efficiency during heterogeneous catalytic oxidation, homogeneous Inhomogeneous mixing of the two phases during phase reactions

These unfavorable factors result in high oxidant consumption and long reaction times (long residence times)
