Abstract
A process to purify wastewater by chemical oxidation is disclosed. The purification is carried out in a fluidized bed of a suitable particulate carrier upon which the iron(III) compound produced by Fenton's reaction crystallizes or coats, thereby reducing the sludge content of effluent over 50%. In addition, the fluidized bed improves the COD removal by way of thoroughly mixing the wastewater with adding agents.
