摘要
采用SBR工艺分别研究了不同盐度驯化下的活性污泥的生物相和结构,及对COD、NH4+-N、TP的去除率。结果表明,随着盐度的升高,活性污泥的微生物种类减少,结构变得紧密细小;盐度在1.5%范围内,SBR工艺对COD、NH4+-N的去除率均达到90%以上;盐度为1%时,TP的去除率为76%。
Used the SBR process separately to study that the biofaces and structure of acclimated active sludge under different salinity,COD,NH4＋-N、TP removal rate.The results show that the COD and NH4＋-N removal rate can exceed 90%under salinity of 1.5%,t he salt is extremely disadvantageous to TP elimination,
