摘要
通过CODMn 和浊度的测定 ,考察了生物活性炭在低温低浊期的去除率。在此基础上 ,对生物活性炭的生物相和显微结构进行了探讨。研究结果表明 ,自然形成的生物活性炭受水温的影响很大 ,且活性炭只起到载体的作用。若采取自然干燥的措施 ,人工固化形成生物活性炭 ,就可以发挥活性炭的物理吸附作用 ,使出水CODMn <2.5mg/L,浊度<2.0NTU ,并能提高活性炭的使用寿命。
The removals of CODMn and turbidity have been studied in a biological activated carbon(BAC) process during the period of low temperature and turbidity. On the basis of the experimental results obtained, microbial specise and microscopic structure of BAC have also been investigated. The experimental results have demonstrated that temperature has great influence on the naturally formed BAC, in which activated carbon acts as only the bio carrier. While naturally dried and artificially immobilized BAC will play a role of physical adsorption, resulting in the effluent CODMn< 2.5mg/L and turbidity< 2.0NTU respectively. Furthermore, the life of activated carbon can be extended by microbial immobilization.
