METHOD OF ADVANCED REMOVAL OF PERSISTENT ORGANIC POLLUTANTS AND HEAVY METALS IN WATER BODY

摘要

The present invention relates to the technical field of environmental protection, provides a method of advanced removal of pollutants in water, and can be used for the advanced removal of persistent organic pollutants (POPs) and heavy metals in a water body. In the present method, first the POPs or heavy metals are captured in a water body by a scavenger and are made to have solid-phase surfaces; an oxidizing agent is then used to oxidize the captured POPs or heavy metals such that the POPs are decomposed, or the heavy metals are converted, due to the oxidization of a complexing agent, from being in complexes to being free and then precipitate into solids, or the heavy metals are converted to having high valences and then precipitate into solids; at the same time the scavenger is restored. The advanced removal of POPs or heavy metals from the water body is thereby achieved, and the scavenger can be recycled. The method of the present invention is highly effective and low in cost, has a simple treatment process, and can achieve the advanced removal of POPs or heavy metals in a water body.
