摘要本文研究了压力曝气条件下微生物活性和沉淀性能。研究表明：曝气压力每增加0.1 MPa，微生物活性增大约1倍；曝气压力为0.25 MPa时，脱气后活性污泥SVI在75～110之间，菌胶团结构较大，质地较紧密，易于沉淀。提高反应器曝气压力，活性污泥微生物的活性和沉淀性能均有所改善。

Abstract: In this paper, the activity and sedimentary performance of microorganism of pressurized aeration bio-reactor are studied. The research show: when pressure increases 0.1 MPa , the activity of microorganism will be doubled. When pressure is 0.25MPa,SVI of microorganism is between 75～110 , larger and dense zoogloea are cultivated. The activity and sedimentary performance of microorganism are improved by increasing aeration pressure.

Key words: pressurized aeration activity of microorganism sedimentary performance
