Method for quickly starting anaerobic ammoxidation reactor

Abstract

The invention relates to a method for quickly starting an anaerobic ammoxidation reactor, belonging to the field of anaerobic ammoxidation reaction. The method comprises the following step: by using activated sludge as a seed sludge and artificially simulated nitrogenous waste water as a culture solution, continuously operating the reactor for at least 50 days, wherein the artificially simulated nitrogenous waste water is composed of 30-60 mg / L ammonia nitrogen, 30-60 mg / L nitrite nitrogen, 125 mg / L potassium bicarbonate, 54 mg / L potassium dihydrogen phosphate and 0.5-5 mg / L ferrous sulfate. The method is simple to operate and easy to implement, has the advantages of no need of any additional energy consumption and abundant iron element sources, and thus, is a practical efficient environment-friendly microbial enrichment technique.

[0001] The invention relates to a method for rapidly starting an anaerobic ammonium oxidation reactor, belonging to the field of anaerobic ammonium oxidation reaction. Background technique

[0002] The rapid start-up of the anammox reactor and the high-efficiency enrichment of anammox bacteria have always been the focus and hotspot in the field of anammox research. Due to the long doubling time of anammox bacteria and the low coefficient of sludge yield, its popularization and application are limited. Many scholars at home and abroad have tried to explore ways to quickly start and enrich anammox bacteria through different methods, and have accumulated a lot of experience that can be used for reference. , Aspects of design and improvement of reactors for enrichment of anammox bacteria. These two aspects of research are based on the principle of maximizing the retention rate of anammox bacteria in the reactor. Although the rapid start-up of the reactor has be...
