Abstract

The invention relates to a portable photocatalysis reactor for processing organic wastewater. The photocatalysis reactor comprises a rotary shaft and a plurality of photocatalysis boards, the multiplephotocatalysis boards are alternately connected with the pipe wall of the rotary shaft, each photocatalysis board is composed of a base board and a photocatalysis reaction gel film wrapping the surface of the base board, each photocatalysis reaction gel film comprises a photocatalysis reaction site and a polar group, the surrounding area of the photocatalysis reaction site is a high adsorption polar group area, the electric charges in the high adsorption polar group area and a non-high adsorption polar group area are both positive or negative, the electric potential in the high adsorption polar group area is higher than that in the non-high adsorption polar group area, and the high adsorption polar group area is formed through grouping of the high adsorption polar groups or weak adsorption polar groups. The photocatalysis reactor has the advantages that the catalysis efficiency is high, the loaded catalyst is not prone to falling off, the structure is simple and the reactor is convenient to carry and use, the reactor is suitable for processing organic wastewater with the high concentration and small range, and has the extremely good popularization value.

Description

technical field [0001] The invention belongs to the field of organic wastewater treatment devices and relates to a portable photocatalytic reactor for treating organic wastewater. Background technique [0002] In recent years, researchers have made significant progress in the study of semiconductor photocatalysts. Photocatalysts with catalytic properties under visible light have become the most eye-catching environmental purification materials, which are widely used in various fields of environmental protection, such as processing The field of organic wastewater treatment of organic pollutants such as dyes or pesticides in wastewater. [0003] The traditional method of photocatalytic degradation of organic matter in water is to disperse catalyst particles into the reaction system, and make full use of the huge specific surface area of ​​nanoparticles to catalyze and decompose pollutants in sewage to achieve the purpose of purifying sewage. For photocatalytic reactors, the r...
