Title:
HALF SHORTCUT NITRATION STARTING METHOD FOR KITCHEN ANAEROBIC WASTEWATER
Document Type and Number:
WIPO Patent Application WO/2019/119756
Kind Code:
A1
Abstract:
A half shortcut nitration starting method for kitchen anaerobic wastewater. On the basis of the characteristics of wastewater, such as high ammonia nitrogen and low C/N ratio, by using a shortcut nitration reactor and utilizing the difference between AOB and NOB oxygen saturation constants, AOB is enriched by limiting the concentration of DO in the reactor, and at the same time, other conditions such as temperature and alkalinity are controlled to accumulate nitrite, so as to start the half shortcut nitration process quickly; and the effluent can meet the inflow requirements of a subsequence anaerobic ammoxidation process. Also disclosed is a half shortcut nitration reactor.
