A type of nutrient needed for microbial growth is carbon-containing compounds. Commonly used are sugars, oils, organic acids, etc., and the role of carbon sources for microbial growth and metabolism is mainly to provide the carbon shelf of cells, which is the energy required for microbial activities.
When the sewage treatment system is just started and commissioned in the new system, a certain proportion of the carbon source needs to be added to maintain the energy required by the microorganisms.
As the protein, nucleic acid and other nitrogen compound materials that make up the organism, the nitrogen compound absorbed from the outside world is called the carbon source of the organism.
Microbial growth and reproduction and product synthesis require nitrogen sources as energy, nitrogen sources are divided into inorganic nitrogen sources and organic nitrogen sources, inorganic nitrogen sources are commonly used as nitrate, ammonia, etc., organic nitrogen sources are commonly used in corn syrup, peanut cake powder and so on.
In the debugging biochemical system, the sewage treatment plant often uses nitrogen sources to replenish the energy of microorganisms and allow microorganisms to multiply and grow rapidly.
Sewage treatment bacteria biochemical debugging culture is the need to add carbon sources, nitrogen sources, phosphorus sources, microorganisms in the biochemical pool to reproduce require a lot of energy, in the cultivation process of sewage inlet and outlet is needed to close for a few days, no sewage flowing in, no supplementary nutrient source, microorganisms in the propagation of no food diet, resulting in death.
For the process of sewage treatment commissioning and cultivation, carbon source and nitrogen source nutrient source are one of the very important. The serious shortage of carbon sources in the debugging and culture of microorganisms will affect the main factors in the ability and efficiency of nitrogen removal and phosphorus removal in the biochemical process.
