Abstract
In order to realize sludge stabilization,reduction and innocuity,an experimental research on the aerobic treatment of thickened and anaerobic digestion sludge in urban sewage treatment plants was carried out.The results show that the aerobic digestion may reduce the content of organic substances and the sludge odor.The aerobic digestion of anaerobic sludge is performed,the sludge stabilization and reduction are reached,and the germs in sludge can be killed.The sludge settleability is enhanced after aerobic digestion.The addition of flocculant improves the dewaterability.
