In the field of water treatmentBiological treatment processThe metabolic activities of microorganisms, especially denitrifying bacteria and polyphosphate accumulating bacteria, such as municipal wastewater denitrification, industrial wastewater biochemical treatment, and landfill leachate treatment, rely on "carbon sources" (carbon containing organic matter) as energy sources and raw materials for synthesizing cells. When the carbon content of raw water is insufficient (such as low carbon to nitrogen ratio wastewater, commonly found in municipal wastewater, aquaculture wastewater, chemical wastewater, etc.), microbial activity will decrease, leading to a decrease in denitrification (removal of total nitrogen) and phosphorus removal efficiency. At this time, it is necessary to manually add carbon source agents, and glucose is a typical "degradable carbon source"
