摘要
水处理反应器中生物絮体可看成球形单元模型，生物絮体随时间变化而生长，体积变大，生物膜增厚，渗透性变坏，内部生物死亡，反应器去污能力下降。适当控制生物絮体的体积可以提高反应器的效率，将生物絮体体积控制问题抽象成反演几何边界数学问题，利用差分方法得到满意的生物絮体半径。
The biological floccules which in water disposing reactor is looked as ball cell model. The biological floccules grow with the time vary,the volume becomes big ,the biological membrane becomes thick; the permeability becomes bad,inner organism dies; and the reactor's decontamination ability decreases. Properly controlling the volume of biological floccules can improve the reactor's efficiency. The satisfactory radius of biological floccules is obtained by using finite-difference method , considering the properly controlling of biological floccules volume as the mathematical inverse problem of geometrical boundary.
