Catalytic ozonation water treatment device

Abstract

The invention belongs to the field of industrial waste water deep treatment equipment, and particularly relates to a multi-stage advanced catalytic ozonation water treatment device. The device mainly comprises a titanium microporous aerator, H2O2 feeding systems, liquid-state specific catalyst feeding systems, solid-state specific catalysts, a corrugated plate demister and a tail gas collection and destruction system. Waste water flows in the treatment device through a water inlet pipe, the bottom, the middle part and the upper part of the treatment device are respectively provided with a different amount of ozone feeding systems, H2O2 feeding systems, liquid-state specific catalyst feeding systems, and solid-state specific catalysts, and meanwhile, tail gas is demisted through a corrugated plate and then is collected and delivered to the destruction system for destruction, so as to avoid the pollution to an environment. According to the catalytic ozonation water treatment device, the color and COD in industrial waste water can be effectively removed, the treatment method is simple, and the cost is low and the treatment efficiency is high.

Description

[0001] Technical field [0002] The invention relates to an ozone catalytic oxidation water treatment device, which belongs to the field of industrial wastewater advanced treatment equipment. Background technique [0003] In recent years, with the rapid development of my country's industrial economy, the amount of industrial wastewater in my country is increasing day by day. A lot of industrial wastewater is typical high-concentration and refractory industrial wastewater, especially COD and chroma, which are difficult to meet the discharge standards, causing great pollution to the surrounding water environment, and advanced treatment of it is imperative. [0004] As my country's various industrial water pollutant discharge standards become more and more stringent, especially COD and chroma, it has become a key obstacle indicator for various industrial wastewater to meet the standards. However, the currently known advanced wastewater treatment technology has sludge Large outp...
