4)  mechanism of membrane fouling
膜污染机理
1.
Filtration characteristics and mechanism of membrane fouling were investigated with MBR mixed liquor.
以膜生物反应器处理市政污水,通过对活性污泥进行终端过滤来反映膜污染机理,实验表明,最初很短时间内膜污染受膜孔堵塞模型控制,之后受沉积层阻力模型控制,后一阶段是膜污染的主要控制阶段;膜的相对通量随过滤时间呈指数衰减趋势,压力越大,通量衰减越快;污泥沉积层存在压密过程,这一过程中的污泥比阻随压力增大而增大,并得到处理市政污水的污泥压密指数为0。

补充资料:A机理
分子式:
CAS号:

性质:缔合机理  association mechanism  简称A机理(A mechanism)。在配位化合物MLnX被Y取代反应中,Y接近MInX,先于X的离去。反应速率决定步骤有中间体生成,具有比原来配位化合物高的配位数。新键的生成是反应速率的决定步骤。例如,反应[Pt(NH3)3Cl]++Br-[Pt(NH3)3Br]++Cl-其反应速率可表示为V=kc[Pt(NH3)3Cl+)c(Br-)。反应速率与配位化合物浓度c(Pt(NH3)2Cl+)及外来配体浓度c[Br-]均有关。其特点是双分子的二级反应。
