| 摘 要： | 在一定条件下，以废硫酸、废铝制品和氧化钙等为原料合成了聚合硫酸铝（PAS）．经测定，PAS碱化度为45％～54％，含铝量为10％（以Al2O3计），PH值为4．12，同标准聚合硫酸铝（PAS）具有相似的性能指标．经红外光谱、X-射线衍射分析，PAS为不同聚合度的铝羟基配合物．经实验证明，PAS具有良好的降化学需氧量（COD）和除油脱色的能力．

| Abstract: | In a certain condition, water treatment coagulant polyaludrinium sulfate (PAS)are prepared by using scrap aluminium products,waste sulphuric acid and calcium oxide. Thebasicity of the product is 45 % ~ 54 %, alundnium content is 10% (as Al2O3 )and pH 4.12.The properties of PAS are close to that of the standard polyaluwhnium sulfate (PAS* ). IRand X-Ray diffraction studies indicate that PAS is composed of hydrolysed aluminium complexes of different degrees of polymerization. The product is used to treatment of sewage,the results showe that PAS has good performances as coagulant with high removal efficiencies of colored matter, turbility and chemcal oxygen demand (CODCr) |
