Characteristics and Functions of Microorganisms:
(1) General
Characteristics of Microorganisms.
Many of the properties of microorganisms make them suitable for use in wastewater treatment. A through knowledge of the different physical and chemical functions of microorganisms is essential to an understanding of liquid waste processing technology.
Microorganisms use fermentation reactions (protein) to perform complex synthesis under normal temperature and pressure. Hence equipment based on microorganism reactions is simpler than equipment employing physico-chemical reactions and processes, and makes it possible for complex reactions to be driven efficiently.
Among living organisms, microorganisms are characterized by rapid proliferation rate, and are capable of rapidly converting substances. (The volume of oxygen consumed by microorganisms is millions of times that required by humans, on a per-unit-weight basis.) .
Microorganism's process materials contained in wastewater, which cannot be decomposed by other means.
Microorganisms regulate themselves so as to form an organic layer suitable for processing liquid waste. (Self-regulating function).
Microorganism reactions are safe, and pose no danger of secondary pollution.
