[0002] Biological wastewater treatment is a general term for treating wastewater using biological methods. It includes traditional activated sludge processes, A / O processes, A2 / O processes, A / B processes, and SBR processes. It is one of the most widely used methods in modern wastewater treatment, primarily relying on the decomposition of organic matter in wastewater by microorganisms to convert it into simple inorganic substances, thus purifying the wastewater. Based on oxygen requirements, it can be divided into two main categories: anaerobic biological treatment and aerobic biological treatment. Anaerobic biological treatment utilizes anaerobic microorganisms to convert organic matter into organic acids, which are then further decomposed into methane, carbon dioxide, and hydrogen by methanogenic bacteria. Examples include anaerobic ponds, septic tanks, anaerobic digestion of sludge, and anaerobic bioreactors.

In traditional high-efficiency microbial treatment tanks, some activated sludge will settle and be adsorbed at the bottom of the tank, resulting in poor activity.
