Abstract

The invention discloses a method for realizing rapid proliferation of anaerobic ammonium oxidation bacteria. In the method for realizing rapid proliferation of anaerobic ammonium oxidation bacteria, based on the maximum electron transfer ability of anaerobic ammonium oxidation bacteria, the anaerobic ammonium oxidation is started in combination of an MBR reactor; and by inoculating the mixed sludge consisting of 90% of nitration sludge and 10% of anaerobic granular sludge, the sludge retention time is gradually shortened, the maximum specific growth rate of the anaerobic ammonium oxidation bacteria is increased, and rapid proliferation of anaerobic ammonium oxidation bacteria is realized. In the invention, based on the characteristics of long start time of anaerobic ammonium oxidation and slow sludge increase, the MBR is combined with the anaerobic ammonium oxidation, the best sludge source is inoculated, and the novel efficient nitrogen removal technology can be applied to practical production in a large scale as much as possible.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a method for realizing rapid proliferation of anammox bacteria. Background technique [0002] With the development of petrochemical, food and pharmaceutical industries, and the continuous improvement of people's living standards, the content of nitrogen compounds in industrial wastewater and domestic sewage has risen sharply. The removal of nitrogen pollutants has become one of the research hotspots in the field of sewage treatment. The traditional nitrogen removal technology consists of two parts: nitrification and denitrification. The traditional biological nitrogen removal method has good treatment effect, stable and reliable treatment process, convenient operation and management, and will not cause secondary pollution. However, the nitrification process requires a lot of energy consumption; the denitrification process requires a certain amount of organic ...
