Nitrosobacteria agent and preparation method thereof

Abstract

The invention discloses a nitrosobacteria agent and a preparation method thereof. The nitrosobacteria agent provided by the invention comprises nitrite bacteria microorganisms and an adsorption carrier, and the adsorption carrier comprises crosslinked chitosan embedded with calcium carbonate and heterotrophic bacteria. The invention also provides a preparation method of the nitrosobacteria agent. The preparation method comprises the following steps: (1) preparing the adsorption carrier; (2) culturing nitrite bacteria type microorganisms; and (3) mixing the microorganisms and the adsorption carrier to prepare the nitrosobacteria agent. The nitrosobacteria agent provided by the invention has the characteristics of high reproduction speed and high biological concentration, and is not easy to lose in the application process.

Description

technical field

[0001] The invention belongs to the technical field of environmental microorganisms, and in particular relates to a nitrosating bacterial agent and a preparation method thereof. Background technique

[0002] The main functional microorganisms in the nitrification process are nitrifying bacteria, which are chemotrophic microorganisms. Biological cells can only use the energy stored in the form of ATP. In aerobic metabolism, ATP is mainly synthesized by oxidative phosphorylation of the respiratory chain. The efficiency of ammonia oxidative phosphorylation is very low, and the ATP that can be produced is very limited. These energy are mainly used for electron transitions to higher energy levels, which makes the growth of nitrifying bacteria very slow. Nitrifying bacteria are further divided into ammonia oxidizing bacteria (nitrite bacteria) and nitrite oxidizing bacteria (nitrite bacteria). The nitrification reaction is terminated when it reaches the nitrous a...
