Distributed photocatalytic remediation system for remediation of organic matters in underground water

Abstract

The invention provides a distributed portable photocatalysis unit based on an ultraviolet light catalysis technology, the distributed portable photocatalysis unit based on the ultraviolet light catalysis technology is excavated out of an outer well to be buried in an underground water pollution layer, and the distributed portable photocatalysis unit based on the ultraviolet light catalysis technology specifically comprises a water inlet chamber, a mixing chamber, a reaction chamber, an ascending chamber and a power chamber which are communicated in sequence, the mixing chamber is provided with a medicament inlet through which a mixed medicament enters the mixing chamber, the reaction chamber is internally provided with an ultraviolet lamp and a catalytic filler, and the ultraviolet lamp emits ultraviolet light to excite the catalytic filler to carry out photocatalytic reaction with underground water mixed with the mixed medicament so as to remove pollutants. The characteristics of efficient underground water pollution treatment, flexible arrangement and convenience in carrying and transferring can be achieved.

Description

technical field

[0001] The invention relates to a groundwater restoration system, in particular to a distributed photocatalytic restoration system for the restoration of organic matter in groundwater. Background technique

[0002] In recent years, with the deepening of groundwater survey work, the impact of industrial and agricultural production and other activities on groundwater has gradually become clear. It has been found that there are many kinds of pollutants in groundwater, among which organic matter (VOCs) pollution is an important type of groundwater pollution. Therefore, it is of great significance for the site remediation industry to innovate the remediation process and equipment of organic matter-contaminated groundwater.

[0003] The remediation methods of organic matter in groundwater can be divided into extraction treatment and in-situ treatment. The treatment methods mainly include chemical oxidation, microbial treatment, chemical reduction, ultraviolet degra...
