Sewage treatment is a simple and complicated matter. Although COD is removed, ammonia nitrogen is degraded, total nitrogen is removed and total phosphorus is reduced in wastewater biochemical bacteria culture, if there is a problem in actual operation, the effluent index will not meet the standard, and it is difficult to find the problem. Today, Bian Xiao gave a brief introduction to some strains needed for sewage treatment, and what should be paid attention to when adding these strains? What are the bacteria in sewage treatment? The content comes from Baidu experience.

Study on Gande -GANDEW-NI denitrifying bacteria;

Nitrification is divided into two stages: nitrosation (ammonia oxidation) and nitrification (nitrite oxidation), which are completed by two types of chemoautotrophic microorganisms respectively. Nitrifying bacteria carry out ammonia oxidation and nitrifying bacteria carry out nitrite oxidation. It consists of 5 genera and 27 different nitrifying bacteria, which can selectively screen and domesticate suitable nitrifying sludge in different sewage quality, and is widely used. It is mainly to remove ammonia nitrogen from water and convert ammonia nitrogen into nitrite and nitrate through nitration reaction.

Glycine-Ganderwei-Deng total nitrogen degrading bacteria;

Denitrifying bacteria are bacteria that can cause denitrification. Most of them are heterotrophic and facultative anaerobic bacteria. Under the condition of xenon, they use oxygen in nitric acid to oxidize organic matter and obtain the energy needed for their own life activities, thus transforming nitrate nitrogen into nitrogen.

Denitrifying bacteria are excellent strains extracted from nature. Nitrate reductase and nitrite reductase can be produced rapidly after being cultivated and domesticated by advanced bio-genetic engineering technology, and then fermented and sealed with unique enzyme and nutrient formula. Nitrate and nitrite can be reduced to nitrogen (N2) or nitrous oxide (N2O) in denitrification reaction, thus achieving the purpose of purifying sewage.

Degreasing bacteria with gande-gande-mixcod;

Gandewe-mixcod sterilization is a compound strain composed of more than 50 kinds of bacteria belonging to 6 genera, which can adapt to different water quality environments, distinguish and select strains with strong specificity independently, and has a wide range of independent applications.

GANDEW-MIX COD removal bacteria mainly include nitrifying bacteria, denitrifying bacteria, Bacillus, Pseudomonas, activating enzymes, polysaccharides and other nutrients. After rejuvenating these ingredients in a proper proportion (privately), we dormant the strains by dry freezing, thus making dry powdery strains.

Glycine-gandu -LIPA lipolytic bacteria;

GANDUEW-LIPA lipolytic bacteria mainly act on lipolysis in restaurants, school canteens and general domestic sewage. LIPA lipolytic bacteria can secrete lipase to decompose oil in vitro, and its oil is composed of glycerol and three fatty acids. Lipa lipolytic bacteria can cut off the combination of three fatty acids and glycerol, and lipolytic enzyme can be absorbed by bacteria as a nutrient in the final stage, thus degrading BOD, COD and some ammonia nitrogen in oil and water.
