好氧颗粒污泥的培养及其特性研究
Research on Aerobic Granular Sludge of Its Cultivation and Characteristics
摘要
Abstract
The experimental study of aerobic granular sludge in a sequencing batch reactor ( SBR ) was performed using a synthetic domestic wastewater and ordinary flocculent activated sludge as inoculation sludge. The conditions under which the successful cultivation of aerobic granular sludge is conducted are as follows; the temperature is room temperature, pH is about 7. 0, aeration time is 150 -180 min, sludge settling time is 9 ~ 120 min, and aeration rate is 0. 3 ~0.5 mVh. The aerobic granular sludge has yellow appearance, with a size of 1 ~2 mm, SVI of 40 mL/g or so, and MLSS of 6 515 mg/L. The average settling velocity is up to 18.42 m/h. Aerobic granular sludge contains large amounts of protozoa, e-merging in groups. The removal rates of COD, TN and TP are up to 95% , 96% and 98% respectively.关键词
