Embodiment 1

[0039] A compound microbial inoculant for deamination nitrogen is prepared from Providencia reinhardtii, Lactobacillus Lactobacillus, Lactobacillus deutscheii and Rhodococcus faecalis in a volume ratio of 5:2.5:1:5.

[0040] The composite microbial inoculum is prepared by the following steps:

[0041] 1) respectively carry out primary seed cultivation activation on respective liquid medium by Providencia reais, Lactobacillus Lactobacillus, Lactobacillus deutsche Bacillus and Rhodococcus faecalis, obtain the activation culture solution of each bacteria;

[0042] The culture conditions are culturing at 25-30°C for 1-2 days;

[0043] 2) The activated culture solution of each bacteria is inoculated on the respective liquid culture medium according to the inoculum amount of 5-15%, and cultivated for 2-3 days under the condition of 25-30 °C, until the number of viable bacteria in the culture solution reaches thunder. Providence spp. 1-9×10 10 pcs / g, Lactobacillus 1-9×10 7 pcs / g, ...

Abstract

The invention discloses an ammonia nitrogen-removed compound microorganism microbial agent. The ammonia nitrogen-removed compound microorganism microbial agent is prepared from Providencia rettgeri, Microbacterium lactium, Lactobacillus delbrueckii and Rhodococcus coprophilus in a volume ratio of 5 to 2.5 to 1 to 5. The invention further discloses application of the compound microorganism microbial agent in ammonia nitrogen-containing wastewater treatment. The four bacteria are reasonably matched and are combined by virtue of an adsorption method and an embedding method to form immobilized cell particles, so that the ammonia-nitrogen degradation capacity and stability of the compound microorganism microbial agent are remarkably enhanced; a dominant bacterial community can be immediately formed after the compound microorganism microbial agent is applied to denitrification and treatment process of sewage, river way landscape water and the like, the treatment time is short, and ammonia and nitrogen indexes of the sewage are rapidly decreased; and meanwhile, the compound microorganism microbial agent has an aerobic denitrification function and further has relatively good effect of removing COD, and accumulation of nitrite and nitrate is avoided.

Description

technical field [0001] The invention belongs to the field of microbial environmental protection, and in particular relates to a compound microbial inoculant for deammonia nitrogen and its application. Background technique [0002] With the development of industrial production and the improvement of people's living standards, the amount of industrial sewage and urban domestic sewage has increased at an alarming rate. These sewage have or are polluting the rivers, rivers and lakes on which human beings live, posing a threat. One of the reasons for the human living environment, especially the water body is polluted by nitrogen. Excessive discharge of nitrogen-containing compounds makes the original ecosystem out of balance, causing algal blooms, resulting in eutrophication of water bodies. Therefore, the removal of ammonia nitrogen is the key to sewage treatment. [0003] Among the existing sewage treatment methods, such as biochemical method, aeration and oxygenation method,...
