Abstract

The invention belongs to the technical field of wastewater treatment, and particularly relates to a method for promoting proliferation of anaerobic ammonium oxidation bacteria. The method for promoting the proliferation of the anaerobic ammonium oxidation bacteria comprises the step of adding an accelerant vitamin C. According to the invention, vitamin C is added to serve as an accelerant to promote proliferation of anaerobic ammonium oxidation bacteria, can improve the denitrification effect of the anaerobic ammonium oxidation bacteria, more importantly shortens the generation time of the anaerobic ammonium oxidation bacteria, and increases the proliferation speed of the bacteria.

Description

technical field [0001] The invention belongs to the technical field of wastewater treatment, and in particular relates to a method for promoting the proliferation of anammox bacteria. Background technique [0002] The anammox process has obvious advantages over the traditional nitrification-denitrification denitrification method. This process can completely change the traditional denitrification process that requires electron donors (carbon sources) to denitrify (denitrification), without the need for additional carbon sources. At the same time, the anaerobic ammonium oxidation process does not require aeration, which reduces the energy consumption of aeration by about 40% to 60%. Anaerobic ammonium oxidation can also minimize the remaining sludge production, thereby saving a lot of sludge disposal costs. If the anaerobic ammonium oxidation is enriched in the reactor in the form of granular sludge, a high volumetric loading rate can be maintained, which not only saves land ...
