Example Embodiment

[0033] Example 1, a paracoccus ammoniaphages ( Paracoccus aminovorans ) LH-N40 CGMCC No. 6971.

Example Embodiment

[0034] Embodiment 2, a heterotrophic nitrification, aerobic and denitrification microbial inoculum, the microbial inoculum includes Paracoccus ammoniaphages ( Paracoccus aminovorans ) LH-N40 CGMCC No. 6971. The content of the strain may be appropriate. In the inoculum, each strain is a strain that plays the role of denitrification and COD removal in the inoculum. The inoculum can be a separate strain, and it can also contain conventional microbial additives, such as stabilizers and / or protective agents. . The strains and their microbial agents can be applied to treat nitrogen-containing industrial wastewater.

Example Embodiment

[0035] In Example 3, in the heterotrophic nitrification and aerobic denitrification microbial inoculum described in Example 2, the content of strains is not less than 0.1% as measured by mass fraction.

Abstract

The invention discloses a Paracoccus aminovorans LH-N40 CGMCC No.6971. The invention also discloses a heterotrophic nitrification-aerobic denitrification microbial inoculum which contains the Paracoccus aminovorans LH-N40. The invention also discloses a preparation method of the microbial inoculum. The microbial inoculum disclosed by the invention can solve the problem of difficulty in removing total nitrogen in the traditional reactor, can effectively remove ammonia nitrogen and total nitrogen in the water body in one reactor, has tolerance or degradation capability for phenols, amines, heterocycles, cyanides, polycyclic aromatic hydrocarbons and other toxic substances in wastewater, is especially applicable to nitrogenous chemical wastewater, has the advantages of simple treatment process, stable effect and environmental toxicant impact resistance, and has very wide application prospects in various actual nitrogenous chemical wastewater treatment processes.

Description

technical field [0001] The invention belongs to the field of environmental microorganisms, and specifically relates to microbial strains, a heterotrophic nitrification, aerobic denitrification and denitrification microbial bacterial agent composed of the microbial bacterial strains, and a preparation method and application of the bacterial agent. Background technique [0002] The traditional wastewater biological denitrification technology mainly relies on autotrophic nitrifying bacteria and heterotrophic denitrifying bacteria to convert ammonia nitrogen into nitrogen gas through nitrification and denitrification coupling. However, the proliferation rate of autotrophic bacteria is slow, they cannot compete with heterotrophic bacteria in the mixed culture activated sludge system, it is difficult to obtain high biomass, and the nitrification efficiency is low, resulting in weak shock resistance of the autotrophic microbial denitrification system. Nitrification is incomplete; d...
