| 摘 要： | 从宏观角度提出了高浓度絮状颗粒污泥的传质物理模型，该模型指出：利用高分子有机药剂使形成的絮状颗粒污泥，在适当剪切条件下始终雏持”包裹-破裂-再包裹”不断循环的过程，絮状颗粒污泥内部微生物与氧气、有机物等物质的接触、吸附和捕获的几率大大提高，既增加了絮体的比表面积，又提高了其微生物的活性．从而解决了高浓度生物处理技术传质效率低的问题，并通过实验验证了该模型．图5，参16．

| Abstract: | This paper created the physical transfer model in the system of high concentration flocculent granule at a macroscopic angle.The model points out: the flocculent granule which is resulted by the high molecular flocculent,remained at the cycle process of"enwrap-fracture-enwrap" at proper shear factor.It can raise the probability that kernel touching,adsorption and trapping of the O2 and organic by microorganism in the granular.It is not only increase the specific surface area,but also raise the activity of m... |
