Title:
METHOD FOR DEGRADING SMALL MOLECULAR ORGANIC MATTER IN REGENERATED WASTEWATER OF WASTE FLUE GAS DENITRATION CATALYST
Document Type and Number:
WIPO Patent Application WO/2020/000342
Kind Code:
A1
Abstract:
A method for degrading a small molecular organic matter in regenerated wastewater of a waste flue gas denitration catalyst, comprising the following steps: step I, wastewater pretreatment; step II, anaerobic hydrolysis treatment; step III, aerobic treatment; and step IV, disinfection and water discharging. In step I, the regenerated wastewater of the waste flue gas denitration catalyst is introduced into an electrochemical reaction device, an electrocoagulation oxidative coupling reaction is performed on the regenerated wastewater of the flue gas denitration catalyst by adding hydrogen peroxide to the electrochemical reaction device, precipitation is performed after the completion of the reaction, the sludge obtained by means of precipitation is discharged, and a supernatant liquid obtained by means of precipitation is drawn by means of a drawing pump to an anaerobic digestion reaction pool.
