Dec 03, 2020

In the biochemical treatment process of industrial wastewater treatment engineering, the microorganisms in the activated sludge continuously consume the organic matter in the wastewater. Among the consumed organic matter, part of the organic matter is oxidized to provide the energy required for microbial life activities, and the other part of the organic matter is used by microorganisms to synthesize new cytoplasm, so that the microorganisms can multiply and multiply.
