　　What does “biology” refer to in membrane bioreactor technology

　　Membrane bioreactor technology (MBR) is a new type of wastewater treatment technology that combines membrane separation technology with biological treatment technology. The “biological” part is one of the core components of this technology.

　　In membrane bioreactors, “organisms” mainly refer to microorganisms. These microorganisms play a crucial role in the wastewater treatment process. They can decompose and transform pollutants such as organic matter, nitrogen, phosphorus, etc. in wastewater, converting them into harmless substances, thereby achieving sewage purification.

　　The term “biological” in membrane bioreactor technology mainly refers to activated sludge. This is composed of microbial communities and the organic and inorganic substances they depend on.

　　Activated sludge in MBR is an important component of this technology. Activated sludge is mainly composed of microbial communities, which parasitize on organic and inorganic substances in wastewater. These microorganisms convert organic matter in wastewater into their own biomass through adsorption, absorption, and degradation in the MBR reactor, while also achieving wastewater purification.

　　The performance and quantity of activated sludge have a significant impact on the treatment efficiency of MBR. High performance activated sludge can quickly and efficiently degrade organic matter in wastewater, improving the treatment efficiency of MBR. At the same time, a sufficient amount of activated sludge can maintain the ecological balance inside the MBR reactor and stabilize the treatment effect.

　　In order to maintain the activity and quantity of activated sludge, it is necessary to regularly maintain and manage the MBR reactor, such as supplementing new microorganisms and adjusting the environmental conditions inside the reactor. In addition, regular monitoring and adjustment of the performance and quantity of activated sludge is also an important measure to ensure the normal operation and treatment effect of MBR.
