System for removing pollutants through aeration by using catalyst under dark condition

Abstract

The invention relates to the technical field of environment protection and pollution control, in particular to a system for removing pollutants through aeration by using a catalyst under a dark condition. The system comprises an aeration vibration chamber and a wastewater treatment chamber, the two ends of the aeration vibration chamber are fixedly provided with a water inlet pipeline and a wateroutlet pipeline respectively, the bottom of the aeration vibration chamber is provided with aeration stone and partition plates, through holes are formed in the bottom of the aeration vibration chamber, and the partition plates are fixedly installed at the through holes. The partition plates has a time switch function, one-way filter devices are fixedly installed in the through holes, each of thetwo ends of the wastewater treatment chamber is fixedly provided with a water inlet pipeline, a water outlet pipeline and a backup water inlet pipeline, the water inlet pipelines, the water outlet pipelines and the backup water inlet pipelines are provided with adjusting valves respectively, and the two ends of the wastewater treatment chamber are fixedly connected with the aeration stone. Under the dark condition, a water solution obtained after being aerated by a photoelectrocatalysis material can efficiently degrade the pollutants which are difficult to degrade, the problem that a traditional photoelectrocatalysis material cannot generate electricity without light is solved, and it is achieved that various typical pollutants which are difficult to degrade are degraded at low energy consumption.

Description

technical field [0001] The invention relates to the technical field of environmental protection and pollution control, in particular to a system for removing pollutants by applying catalyst and aeration under dark conditions. Background technique [0002] In recent years, with the rapid development of my country's economy, the reduction of fresh water resources, energy consumption and water pollution in various industrial areas have become increasingly prominent along with the development, and have gradually become the topic of discussion and the research direction of scientific researchers. [0003] At present, the most prominent representative in the research on the degradation of pollutants is photocatalytic materials, which irreversibly change the reactant molecules and strongly affect the degradation efficiency of certain pollutants in the water environment. When irradiated by light with energy greater than the forbidden bandgap energy of the photocatalyst, the electron...
