Embodiment Construction

[0024] The following is further described in detail through specific implementation methods:

[0025] An aerobic denitrification bacterial agent, including a bacterial agent and a culture medium, the bacterial agent is composed of Klebsiella pneumoniae bacterial liquid, Raoultella vegetative bacterial liquid, Bacillus curvedus bacterial liquid, Sphingobacterium bacterial liquid, Kreb Bordetella bacterial liquid, Acinetobacter baumannii bacterial liquid and Pseudomonas steeriella bacterial liquid.

[0026] Examples 1-16 are examples of the present invention. Table 1 shows the amount of each bacterial solution added per 100 mL of bacterial agent, and the total amount is adjusted with a culture medium, unit: mL.

Abstract

The invention relates to the field of sewage treatment and particularly discloses an aerobic denitrification agent. The aerobic denitrification agent comprises a klebsiella pneumoniae solution, a raoultella planticola solution, a bacillus flexus solution, a sphingobacterium multivorum solution, a klebsiella solution, an acinetobacter baumannii solution and a pseudomonas stutzeri solution. A preparation method of the aerobic denitrification agent comprises the steps as follows: step a, strain activation; step b, enlarged culture; step c, agent preparation: preparing bacteria solutions in the step b into a mixed bacteria solution, inoculating an aerobic denitrification culture medium with the mixed bacteria solution for constant-temperature shake culture for 24-48 h, and collecting the agentand packaging the agent in sterile containers for storage when the total count of microbes is larger than 109 CFU/ml. The technical scheme solves the problems of high cost and high management difficulty in the sewage treatment process in the prior art.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to an aerobic denitrification bacterial agent and a preparation method thereof. Background technique [0002] In recent years, my country's industry has developed rapidly. At the same time, the discharge and pollution of industrial wastewater have become increasingly prominent. Industrial wastewater usually includes various polluting and toxic substances such as organic and inorganic solids, sulfides, ammonia nitrogen compounds, heavy metals, and surfactants. Among them, ammonia nitrogen compounds can be decomposed into nitrogen oxides. Nitrogen oxides are an air pollutant that seriously endangers human health and destroys ecological balance. More and more attention has been paid to its governance. At present, the main measures to control ammonia nitrogen compounds are mainly chemical denitrification and biological denitrification, and chemical denitrification has been gradually eli...
