Progress of research on environmental factors affecting biofilter efficiency in recirculating aquaculture system
摘要
Abstract
Treatment and reuse of aquaculture wastewater is the key technology in recirculating aquaculture systems (RAS). Biofilter, a core unit in RAS, plays a vital role in removal of pollutants in aquaculture water. Water temperature, salinity, pH, dissolved oxygen ( DO ) and other environmental factors can affect the function of biofilter. Sudden changes of environmental factors can cause biofilm degradation or dropping off, which may seriously affect biofilter growth and water treatment effects. Biofilter efficiency can achieve the ideal state and aquaculture wastewater treatment effect be improved when the water temperature, salinity, pH and DO are well under control. It is necessary to study biofilter’ s kinetics of aquaculture wastes removal under each environmental factor, so as to provide a theoretical basis for optimizing design and operation management of RAS.关键词
