Introduction to the technology
The removal of biodegradable organic matter, as well as nitrogen and phosphorus by means of biological decomposition is the most economical and simple method of wastewater treatment and is widely used in municipal services.
Biological wastewater treatment is based on the ability of microorganisms to decompose organic matter present in wastewater, using it for their nutrition and ensuring their own growth and reproduction. In addition to organic matter, microorganisms need trace elements (mainly nitrogen and phosphorus), the excess of which is also contained in wastewater. The main link in the treatment facilities, where microorganisms are located and the biological treatment process takes place, is the bioreactor. Subsequently, after treatment, the water is discharged from the facilities, and the microorganisms remain in the bioreactor. Thus, microorganisms are responsible for the removal of organic substances present in water both in solid (in the form of suspended particles) particles and in dissolved form. There are aerobic (in the presence of air supplied to the bioreactor) and anaerobic (without air supply) purification processes. In modern bioreactors, both of these processes are often carried out, separated in space or time. The design of a bioreactor consists in the optimal selection and arrangement of biological processes occurring in it.
The set of microorganisms in a bioreactor is very diverse and rich. The diversity of species of organisms and their composition depends on the properties of the wastewater being treated and the conditions of the technological process. In other words, a kind of ecosystem is formed in the bioreactor, which continuously adapts to changing external conditions.
The limitations of this type of treatment are related to the possibility of biodegradation (decomposition) of pollutants and the presence of biocides in wastewater (substances that inhibit (slow down) biological processes and the growth of microorganisms).
