Interaction between Sludge Bioflocs and Emerging Pollutants

Time:

 

Address:

 

Sludge biofloc is an amorphous flocculent formed by microorganisms, extracellular polymers and adsorbed organic, and inorganic substances. It plays an?essential role in the wastewater biological treatment?and serves as?a biological carrier of pollutant migration, transformation and biodegradation. In recent years, emerging pollutants such as antibiotics and nanoparticles have been frequently detected in water. The research shows that they have potential risks to public health and water ecology. The research and pollution control of emerging pollutants have attracted much attention. Wastewater treatment plants are considered to be an important gathering place for various pollutants, which is a key link in controlling pollution discharge. A large number of studies have shown that emerging pollutants with strong biological activity will have a series of important impacts on sludge bioflocs after entering the biological process, including inhibiting nitrification reaction, reducing organic matter removal efficiency, destroying sludge flocculation structure and granulation, inhibiting anaerobic nitrification process, etc.?Consequently,?these pollutants affect the operation of wastewater treatment plants and causing environmental diffusion of emerging pollutant, threatening the ecological environment and human health. Therefore, the study on the interaction between sludge bioflocs and emerging pollutants has important scientific value and practical significance. This sub-forum will focus on the interaction between emerging pollutants?and sludge bioflocs, merging pollutants including nanomaterials, microplastics, chlorine disinfectants and antibiotics. The interaction contains the influence of pollutants on the formation and physical and chemical properties of floc, the influence and mechanism of pollutants on the microbial community of floc, and the interface behavior of pollutants on the surface of floc and others.
