Technical introduction

According to the actual situation of wastewater, after the wastewater is biochemically treated, most of the remaining COD is difficult to degrade organic matter, which brings great difficulty to COD degradation, and routine methods are difficult to decompose.

After using UV-APOS technology, UV-AOPS modules are jealous under specific light source, and the ultraviolet light and hydrogen oxygen in the UV-AOPS module are coupling, and the organic matter is expireced from the hydroxyl group released by ultraviolet light. A portion of the organic matter is further reduced by the chain or molecular weight under the ultraviolet photocatalytic action, and the small molecular material is further mineralized under strong ultraviolet light, and final COD is discharged.

 working principle 

When the R molecules in the sewage absorbed to be rich in light (ultraviolet light), the excited state R * molecule is converted to a higher energy level, which increases the energy and the input photon energy, becomes excited state. The post-molecule is more likely to produce a broken chain.

Hydrogen peroxide (H2O2) is permeable to hydroxy free radicals in an appropriate wavelength, which can quickly react quickly with organic and inorganic materials in water and generate inorganic products such as water, and the like.

The presence of hydroxyl radicals (HO *) can greatly accelerate the process of contaminant decomposition. Therefore, there is no need to use a large number of chemicals.

Core composition

The core technology of the UV-APO is that the specific ultraviolet light source. Unlike conventional sterilization of ultraviolet light sources, photocatalytic oxidation has a high light energy density, which has a specific wavelength distribution, which is advantageous to produce more hydroxyl radicals in the reaction system, so that it can be placed Good degradation of COD.

Technical advantages

At present, the commonly used advanced oxidation process mainly has a Fenton oxidation method, an electrocatalytic oxidation method, a ferroelectric solution, and a UV-APO in an inner photocatalytic oxidation method, and the following is compared.

Technical point

Based on the characteristics of wastewater and the results of our preliminary experimentation, in the principle of investment, the highest improvement effect is the principle of design, and our company provides UV-Catalytic Oxidation Technology (TK-LH) to handle it. The core points of the program are as follows:

(1) UV-APO module part, using flat throttle reactor form, continuous importance water;

(2) The entire device is simple, and it can be automatically run after booting, and there is no need for excessive artificial intervention.
