Light promoting dehalogenation compound medicament/light combined method for removing halogenated organic matters in water

Abstract

The invention provides a light promoting dehalogenation compound medicament/light combined method for removing halogenated organic matters in water, which relates to a method for removing halogenated organic matters in water. The invention overcomes various defects existing in the process of removing halogenated organic matters in water by using the current gas stripping method, activated carbon adsorption method, electrochemical removing method, advanced oxidation method, transition metal catalytic reduction method, vacuum ultraviolet technique or permeable reactive barrier technique. The method of the invention comprises the following steps: adding the light promoting dehalogenation compound medicament into the water containing halogenated organic matters for stirring, and then, carrying out optical radiation. The method of the invention does not need multi-stage removal, does not need expensive oxidants and catalysts, does not generate secondary pollution, does not need expensive vacuum ultraviolet light sources and high-energy radiation sources, can utilize common and cheap ultraviolet pop light sources or even expanding to visible light sources, improves the utilization efficiency of the light energy, can quickly remove the halogenated organic matters, can conveniently design a reactor, meets the requirements of various water bodies, is convenient in management, and can ensure the safety of the water quality.

AI Technical Summary

Benefits of technology

The technical purpose described in this patented patent relates to improving the performance of chemical agents called hydrogen peroxides (HP) during treatments like desalination processes. These chemistries help break down harmful materials found naturally occurring in aqueous environments while maintain their beneficial properties over time. They work well at different stages of cleanup operations where they replace older ones before being treated again. Additionally, these techniques allow us to efficiently separate halogened organoids from other types of contaminating elements in waters effectively.

Problems solved by technology

Water purification technologies based on various methods like ion exchange reservoir copper precipitating agents, reverse osmosis membranes, supercritical fluid extractions, plasma decompositions, sonorous atom absorbing techniques, and other processes require long periods of time and significant investment expenses. These technical problem addressed by the inventors include finding new ways to efficiently treat harmful contamination without causing environmental issues associated with current methods.
