The advantages of microbial treatment bacteria in sewage treatment

1. the economic aspect: the economic consumption of microbial strain treatment wastewater including microbial strain, microbial strain growth required nutrient source (carbon source, nitrogen source, phosphorus source) and adjust the PH of wastewater required agents;  An aeration unit that provides a source of oxygen for microorganisms;  Sewage sludge reflux device, sludge disposal device, etc.  Microorganisms have very good adsorption and sedimentation, strong degradation ability, do not need high temperature, high pressure and other harsh requirements, compared with the physical and chemical method of wastewater treatment equipment and long-term dosage of pharmaceutical comparison, the treatment cost is relatively low.  Therefore, the current wastewater treatment is to improve the biochemical properties of wastewater by physical and chemical methods, and then use biological methods to treat wastewater.

2. Environmental pollution: microbial treatment of wastewater is the final conversion of pollutants in wastewater into carbon dioxide, nitrogen, water and sludge.  Nitrogen dioxide, nitrogen and water are non-toxic and harmless. Sludge can also be converted into organic fertilizer through sludge digestion. Sludge can also be used to make building materials.  The results show that there are no secondary pollutants in microbial wastewater treatment and it will not pollute the environment.

3. Treatment effect: micro-biological treatment of wastewater, the degradation of organic matter in wastewater into carbon dioxide, nitrogen, water and sludge itself to remove organic matter;  Microbial treatment of wastewater, wastewater pathogens adsorption and phagocytosis and other ways to remove pathogens;  Microbial treatment of wastewater, the harmful substances in wastewater oxidation into non-toxic position or adsorption to the sludge in order to remove harmful substances;  Microorganisms treat wastewater by adsorption, degradation and sedimentation to improve water quality transparency and reduce chroma.  Most of the pollutants in wastewater can be degraded by selecting suitable microbial strains.
