  • 摘要:采用一定铝总量[Al]T的不同羟铝比(r=[OH]/[Al])的PAC溶液对有机溶胶进行混凝实验。结果表明,聚合氯化铝表面张力(σ)与有机溶胶的COD去除率呈正相关。根据溶液表面张力与溶质水合能力的关系和不同羟铝比的聚合氯化铝中各种羟铝配离子的相对含量,探讨聚合氯化铝对有机溶胶的混凝机理。
  • Abstract:Coagulation experiments were carried out with PAC solution in various Hydroxy Aluminium ratio ( r =/) with a given amount of Aluminium (Al T).The results showed that surface tension of PAC σ has a positive relation with the removal ratio of organic collosol (COD).According to the relative content of various hydroxy aluminium coordinate ion in PAC solution of different Hydroxy Aluminium ratio r and the relation between surface tension of the solution and the hydrous ability, the mechanism of PAC to organic collosol is discussed.
