Method and device for enriching anaerobic ammonium oxidizing bacteria based on modified basalt fiber filler

Abstract

The invention discloses a method and a device for enriching anaerobic ammonium oxidizing bacteria based on modified basalt fiber filler, and belongs to the technical field of sewage biological treatment. The method is characterized by comprising the following steps: S1, starting a system, mixing nitrified sludge with anaerobic ammonium oxidized sludge, then adding the mixed sludge into a reactor filled with modified basalt fibers, and mixing the sludge thoroughly; S2, in an initial stage of culturing, sending matrix raw water into the reactor; at the same time, turning on circulating water forcircular flow; and S3, in a logarithmic growth phase, controlling the water inlet speed of the raw water matrix for continuous rapid enrichment culturing of the anaerobic ammonium oxidizing bacteria.By adopting the method for enriching the anaerobic ammonium oxidizing bacteria provided by the invention, the generation cycle of the anaerobic ammonium oxidizing bacteria can be effectively shortened, high-activity proliferation in a short time can be realized, effective enrichment culturing of the anaerobic ammonium oxidizing bacteria can be implemented, and a foundation is laid for the engineering application of the novel biological denitrification technology.

Description

technical field [0001] The invention relates to the technical field of sewage biological treatment, in particular to a method for enriching anammox bacteria based on modified basalt fiber filler. The enrichment method of anammox bacteria involved in the present invention can effectively shorten the generation cycle of anammox bacteria, realize high-activity proliferation in a short period of time, and carry out the enrichment and cultivation of efficient anammox bacteria, which is a new type of biological detoxification method. The engineering application of nitrogen technology lays the foundation. Background technique [0002] The key to the anammox denitrification technology is the enrichment culture of anammox bacteria (Anammox bacteria). At present, there is no relevant report on the successful purification and isolation of Anammox bacteria by any authoritative institution, and there are no relevant preservation records in the strain banks of ATCC (American Type Culture...
