AUTOTHERMAL CATALYTIC PROCESS FOR DEODORIZING AND DENITROGENATING POLLUTANT DISCHARGES

摘要

The present invention relates to a catalytic process for deodorizing and denitrifying contaminant waste, in particular a method comprising converting mercaptans and hydrogen sulfide and oxidizing volatile compounds, in particular ammonia.;The method of the present invention comprises two steps:;(a) converting mercaptan to disulfide and hydrogen sulfide to sulfide; And;(b) catalytic oxidation of volatile compounds, in particular catalytic oxidation of ammonia.;The process of the present invention works autothermally because the energy produced by catalytic combustion of ammonia and other volatile compounds is recovered by a series of exchangers, raising the temperature of the wastewater to be treated.
