摘要
通过电子显微镜分析了生物活性炭(BAC)的结构特征 ,证明BAC的形成是由于炭粒表面的不均匀性、保护胶体和化学键的结合等综合作用所致。粘液性物质的存在 ,使BAC逐渐成熟稳定 ,保证了BAC具有稳定和高效的去除率。同时 ,还探讨了固定化BAC与自然形成BAC之间的区别。在分析BAC协同净化作用的基础上 。
The structural features of BAC (Biological Activated Carbon) were analyzed by means of electronic microscopic analysis and the formation of BAC was due mainly to the unequal characteristics of carbon articles’surface, the combination of protective colloid and chemical bond etc comprehensive actions The existence of mucous substances made BAC mature and stable gradually, thus ensuring BAC performing a stable and high removal rate In addition, the difference between immobilized BAC and naturally formed ones was studied as well Furthermore, the functional mechanism of biological regeneration of activated carbon was proposed in this study based on the analysis of cooperative purification of BAC
