强化反应器中好氧颗粒污泥与普通活性污泥性质的比较研究

STUDY ON THE DIFFERENCE BETWEEN AEROBIC GRANULES CULTIVATED IN REINFORCED SBR AND CONVENTIONAL ACTIVATED SLUDGE

在SBR中利用优势混合菌，活性污泥和大豆深加工废水，经过19d的驯化，培养出好氧颗粒污泥．从第19天到第34天，对好氧颗粒污泥与普通活性污泥的性质进行比较发现，好氧颗粒污泥在污泥颗粒强度、污泥比重（1．084～1．087g·cm^-1）、含水率（97．30％～97．78％）、沉降指数（60～96mL·g^-1）、VSS／TSS（85．45％～87．69％）等性能指标上均优于普通活性尹泥．

In this paper aerobic granules were cultivated succefully by superior mixed flora, activated sludge and soybean waste water in SBR after 19 days＇ acclimation. Compared with conventional activated sludge, aerobic granules had many advantages in density （ 1. 084 - 1. 087 g · cm^-3）, water content （97. 30% - 97.78%）, SVI60-96 mL· g^-1）, VSS/TSS（ 85. 45% -87.69%） and so forth during day 19 -34.
