The treatment effects and advantages of membrane bioreactors inwastewater treatment and reuse

The membrane bioreactor (MBR) is an efficient wastewater treatment technology that combines membrane separation technology with biological treatment technology. It effectively separates the microorganisms in the bioreactor from the wastewater through the MBR membrane, achieving deep treatment of wastewater with significant treatment effects and prominent advantages, which is widely used in the treatment and reuse of urban wastewater and industrial wastewater.

Firstly, the treatment effect of the membrane bioreactor in wastewater recycling treatment

The treatment effect of the membrane bioreactor in wastewater recycling is significant, and its treatment efficiency is much higher than that of traditional wastewater treatment processes. The membrane bioreactor combines activated sludge and membrane separation technology, removing suspended solids, pathogens, colloids, and organic matter from wastewater through the filtration action of the membrane, achieving reuse water quality standards. Simultaneously, due to the efficient retention effect of the membrane, microorganisms in the reactor have sufficient living space and nutrients, thereby enhancing microbial activity, strengthening biological degradation capacity, and improving treatment efficiency.

　　When treating industrial wastewater, the membrane bioreactor can effectively remove pollutants such as COD, BOD, SS, ammonia nitrogen, total nitrogen, and total phosphorus, with a removal rate of over 90%. In treating urban wastewater, itcan effectively remove pollutants such as COD, BOD, SS, ammonia nitrogen, total nitrogen, and total phosphorus, with a removal rate of over 95%. In treating high-concentration organic wastewater, the membrane bioreactor can achieve ultra-low COD emissions, with a COD removal rate of up to 98% or more.
