摘要:在序批式活性污泥反应器(SBR)内通过逐步提高进水中聚丙烯酰胺(PAM)的浓度实现了好氧颗粒污泥的驯化。经过43d稳定运行,成功培养出性状良好且对PAM具有较高降解活性的PAM好氧颗粒污泥,其PAM平均降解速率达2.230mg/(L·h)。系统内PAM好氧颗粒污泥的混合液悬浮固体(MLSS)为9.85g/L,污泥体积指数(SVI)为39.21mL/g,湿污泥密度为1.034g/cm^3,平均粒径为1.85mm,单个颗粒污泥的沉降速率为8.2~12.8mm/s。
The aerobic granular sludge cultivated in a synthetic glucose wastewater was acclimated and employed for treatment of a synthetic polyacrylamide (PAM) wastewater in sequencing batch bioreactors. During the 43-day acclimation of 6 operating phases, the concentration of PAM in influent was increased gradually. After the acclimation, the spherical PAM aerobic granules were highly effective for PAM degradation with an average degradation rate of 2. 230 mg/(L · h). The mean diameter of the aerobic granules was 1. 85 mm, and the measured settling velocity ranged 8.2-12.8 mm/s. The PAM degrading sludge granules had a MLSS of 9.85 g/L, SVI of 39.21 mL/g, and a density of 1. 034 g/cm^3.
