| 摘 要： | 以核磁共振法测定结果为依据。将聚合铝划分为3种组成形态，通过实验研究了具有不同铝形态分布的聚合铝的絮凝效能。结果表明，聚合铝的絮凝效能随Al13含量的增加而显著提高，在碱性及中性环境中，聚合铝的三种形态中凝聚絮凝能力由强到弱依次为Al13，Alu和Alm。残留铝含量与絮凝剂絮凝效能成反比。

| Abstract: | The coagulation behavior of a series of polyaluminum chloride produced by electrolysis process, with different contents of aluminum species (Al m, Al 13, Al u which were detected by 27NMR) was investigated. The results show that the coagulant efficiency is enhanced by high content of Al 13 species because of its characteristics of higher positive charge and strong binding ability to aggregates. These special properties of Al 13 contribute to superior behavior in coagulation. The coagulation ability of different aluminum species is Al 13>Al u>Al m. The content of remnant aluminum is lower when higher coagulation efficiency is achieved. |
