Abstract

The invention relates to a method for preparing a particle-catalytic electrode material, which belongs to the technical field of wastewater treatment. The method aims to solve the problems of low current efficiency and high energy consumption of the prior particle-catalytic electrode. The method uses a preprocessed natural mordenite as a carrier and a bicomponent oxide containing Sn and Ti as a load layer to prepare the particle-catalytic electrode material. The particle-catalytic electrode material has the advantages of large area-volume ratio, quick mass transfer velocity, good catalytic effect, high current efficiency, low energy consumption, less investment, wide range of application and the like.

Description

technical field [0001] The invention belongs to the technical field of waste water treatment, in particular to a porous zeolite loaded SnO used for treating refractory organic waste water 2 / TiO 2 Preparation method of particle catalytic electrode. Background technique [0002] With the continuous development of the modern chemical industry, the quantity and types of refractory organic matter entering the water body through various channels have increased sharply, causing serious pollution to the water environment and directly threatening human health. Such pollutants are easy to accumulate in organisms, and they are also likely to become potential pollution sources of water bodies, thereby causing harmful effects such as poisoning and "three-caused" effects on organisms or humans. The treatment of refractory organic wastewater is a research hotspot and difficulty in the field of wastewater treatment. [0003] Researchers have proposed many treatment methods for refractor...
