摘 要: | 挂膜是生物流化床正常运行的关键。通过对生物流化床挂膜试验的研究发现 ,生物膜的形成可分为可逆附着、局部固定附着、生物膜的形成、生物膜脱落四步。活性炭吸附作用对挂膜初期COD的下降贡献很大。 2 4天后挂膜成功

Abstract: | The formation of biofilm is the key step of biological fluidized-bed's operation.During the research of biofilm's formation,we divided the period into four steps:reversible adhesion,partly adhesion,maturity of biofilm and the abrasion of biofilm.The absorption of GAC attributed the removal of COD at the beginning of the experiment.After 24 days,the biofilm formation was successful. |
