Abstract
At present,the domestic sewage treatment plant primarily utilizes the activated sludge process.Main-stream processed,such as SBR,CAST,and oxidation ditches,are activated sludge as the core.Activated sludge consists of various microorganisms,including bacteria,fungi,protozoa,metazoa,etc.During sewage treatment process,biological ad-sorption and metabolism facilitate the degradation of pollutants in sewage to achieve the role of sewage purification.After completion of the purification mission,a large amount of residual activated sludge needs to be treated every day,because of its high moisture content,large activity,difficulty in dehydration,and other characteristics,it has become a longstanding,large,and difficult problem for each sewage treatment plant.The reuse method of residual activated sludge developed in the past 20 years of operation and commissioning is introduced.关键词
