Study on short-cut nitrification aerobic granular sludge cultivation and carbon-nitrogen removal

摘要：

Acclimation of short-cut nitrification aerobic granular sludge with aerobic granular sludge and nitrification sludge as seed sludge in a sequencing batch reactor(SBR) by controlling the pH,influent ammonia concentration,temperature and other conditions.Experimental results showed that the short-cut nitrification aerobic granular sludge with high ammonia and COD removal rate (95％) was formed successfully,and SBR can run long-term stably.DO at 6.0～8.0mg/L when the nitrosation rate remained stable at 50％ ～ 60％,and lower DO levels within the reactor (2.0～3.0mg/L) nitrosation rates of up to 90％.Mature short-cut nitrification aerobic granular sludge average diameter of 2～3mm in between,MLSS of up to 10.162g/L,SVI minimum up to 22.63ml/g,moisture content is only 81.93％,total nitrogen removal rate of 40％,and carbon-nitrogen removal capability.
