Abstract

Abstract

The influence of the rapid formation of aerobic granular sludge was investigated in sequencing batch reactors ( SBR) inoculated conventional activated sludge with synthetic domestic wastewater， adding fine soil and anaerobic granules respectively． The results showed that both methods could promote the formation of aerobic granules，the average particle size of the granules in the reactor dosing fine soil was between 0. 4 ～ 0. 5 mm three weeks later，and particle size of the granules in the reactor adding anaerobic granules was 0. 8 mm in 15 days，as the blank experiment was 0. 3 mm after running a month． SEM shows that the cultured aerobic granular has dense structure，high porosity，and a large number of bacillus and filamentous on the surface of the particles．
