Application status of bioaugmentation technology in wastewater treatment
Bioaugmentation technology refers to the addition of microorganisms,nutrients or matrix analogues with specific functions to the wastewater biochemical treatment system,in order to improve the degradation of pollutants in wastewater by the biochemical treatment system.In this paper,the concept and mechanism of bioaugmentation technology are intro-duced,and the application status of bioaugmentation technology in the fields of low-temper-ature sewage,refractory organic wastewater,high-salt wastewater,denitrification and phos-phorus removal of wastewater,remediation of groundwater contamination,and sludge reduc-tion are discussed.The actual treatment effect and application prospect are evaluated.As a new type of environmental pollution control technology,bioaugmentation technology has the advantages of high treatment efficiency,low investment and operating costs,and strong resis-tance to shock loads,which is a new direction for the research and application of wastewater biological treatment in the future.
