摘 要:
以普通絮状活性污泥为种泥，分别采用葡萄糖和乙酸钠为碳源的模拟污水，在特定的有机负荷、沉淀时间、排水比、上升流速、曝气方式和曝气量等条件下，在小试规模SBR反应器内成功培养出小区污水处理用的好氧颗粒污泥。该好氧颗粒污泥对于小区生活污水CODCr和总氮的去除率分别达到86.4％和87．8％。[著者文摘]

Abstract:
The activated sludge was selected as seeding sludge, and the synthetic sewage with different carbon sources of glucose and sodium acetate were fed. With the specific values of process parameters which include organic loading, settling time, volume exchange ratio, upflow velocity, aerating mode and air flow, the aerobic granular sludge for residential sewage treatment was developed successfully in a bench-scale SBR reactor. The removal efficiencies of CODcr and TN in the residential sewage were 86.4% and 87.8%, respectively.[著者文摘]
