Deep oxidization water treatment method and deep oxidization water treatment device

Abstract

The invention relates to a deep oxidization water treatment method and a deep oxidization water treatment device; the deep oxidization water treatment method and the deep oxidization water treatment device are formed by utilizing a high dissolved ozone amount air dissolution technology and a micro-bubble aeration technology in combination with use of ozone, ultraviolet photocatalysis and a photosensitive chemical catalyst; dissolved oxygen and ozone are utilized; furthermore, a large number of hydroxyl radicals excited by ultraviolet photocatalysis chemical reaction can participate in the so-called oxidization chain reaction; and a deep oxidization technology is higher in oxidation capacity and rapider in oxidization speed. The deep oxidization water treatment method and the deep oxidization water treatment device disclosed by the invention are not only applied to sterilizing ordinary drinking water but also applied to oxidizing and degrading organic pollutants, which are difficult to biodegrade and high in concentration and toxicity; and the deep oxidization water treatment method and the deep oxidization water treatment device not only can be used as an independent sewage treatment method and an independent sewage treatment device but also can be used as a pre-processing method for reducing the concentration and the toxicity in sewage used with the existing biodegradable water treatment technological method and equipment in a matched manner.

Description

Technical field: [0001] Using high-dissolved ozone technology and micro-bubble aeration technology, combined with ozone, ultraviolet light catalysis and photosensitive chemical catalyst to form a deep oxidation water treatment method and device, not only using dissolved oxygen and ozone, but also mainly using chemical reaction excitation A large number of hydroxyl radicals participate in the oxidation to form the so-called chain reaction, which is a deep oxidation technology with higher oxidation ability and faster oxidation speed. The invention is not only suitable for disinfection of ordinary drinking water, but also suitable for oxidative degradation of high-concentration and high-toxicity organic pollutants that are difficult to biodegrade in water. It can be used not only as an independent sewage treatment method and device, but also as a pretreatment method for reducing sewage concentration and toxicity and used in conjunction with existing biodegradable water treatment ...

AI Technical Summary

Problems solved by technology

Chinese patent (publication number CN202625991U) proposes a kind of ultraviolet light ozone catalytic reaction device, but the catalytic reaction environment is in the normal pressure container, and the saturated solubility of ozone is relatively small, the ozone of the ozone oxidation reaction (hereinafter referred to as ozonation) under photocatalysis Low saturation solubility still restricts the ability and speed of UV photocatalytic oxidation reaction

Since ozone cannot fully dissolve into the water body, it is difficult to remove some pollutants in a small amount in the water body. Even if the method of excessive ozone exposure is commonly used, the effect is not obvious.
