摘要
EM对SBR反应器的影响进行了初试研究,主要考察了在pH值为8.0,EM接种量为1∶10000(VEM:V污水)条件下,SBR反应器对生活污水中COD,T P,NH3-N的去除效果,以及对污泥性状改变的作用,得到了COD去除效果好于普通SBR(最高可达17.7%),NH3-N去除率两者持平,T P去除效果不明显,以及EM菌群能优化污泥性状的结论,并在此基础上确定了最佳运行模式,为下一步研究提供了一定的基础。
With the purpose to study the function of SBR with effective microorganisms (EM), removal efficiency of COD, TP, NH_3-N in sewage by SBR under conditions of pH 8.0 and V_(EM)∶V_(sewage)=1∶10000 was investigated. Results showed that EM can increase the removal efficiency of COD, while the removal efficiency of TP is not obviously, sludge properties can be optimized when seeding the EM continually.
