Winter environmental microbial agent for sewage treatment plant

The growth of microorganisms used for sewage treatment is greatly inhibited when the temperature is below 5℃. They can grow and reproduce normally in the range of 10-40℃, but grow and reproduce slowly in the range of 10-15℃ and accelerate with the increase of temperature. 25-37℃ is suitable for growth and reproduction, and it takes about 20-30 minutes to reproduce in the case of sufficient carbon source (that is, rich organic matter).  When the temperature exceeds 48℃, the growth and reproduction are inhibited, but they can also reproduce. When the temperature exceeds 50 ℃, the microorganism reproduction is greatly inhibited, and the sewage becomes black, stinks and dies.

Common strains used in industrial sewage treatment or domestic sewage treatment are:

The compound strain: has the strong adaptability that other bacteria do not have, has the good effect in different industrial wastewater, after acclimation, the salinity resistance is up to 2%, the starvation time can reach more than 10 days, low temperature resistance and impact resistance.

Nitrifying bacteria: different nitRIfying bacteria composed of complex bacteria, so it can be selected and acclimated in different sewage water quality suitable nitrifying bacteria, applicable and broad.

Nitrification is divided into two stages, namely nitrification (ammonia oxidation) and nitrification (nitrous acid oxidation), which are completed by two types of chemoautotrophic microorganisms, respectively. Nitrifying bacteria perform ammonia oxidation and nitrifying bacteria complete nitrous acid oxidation.

Denitrifying bacteria: extraction in the fine strains of nature, through the advanced biological genetic engineering breeding and domestication, again with unique formula fermentation enzymes and nutrients storage, can quickly produce in denitrification reaction of nitrate reductase and nitrite reductase nitrate and nitrite reduction into nitrogen gas (N2) or nitrous oxide (N2O), achieve the goal of sewage treatment.

The denitrification ability is strong, can use nitrite nitrogen and nitrate nitrogen as nitrogen source, activation is simple, reproduction is rapid, the effect is remarkable.
