摘　　要：用普通的混凝剂(聚铝,硫酸铝)和改性聚合氯化铝铁对城市污水进行化学一级强化处理的对比,通过静态和动态的实验,分析了COD和磷酸盐的去除效果。实验的结果表明,添加微量阳离子聚合物的改性聚合氯化铝铁对于强化一级处理具有很好的效果,是一种比较实用的混凝剂。Adopting common coagulant （polyaluminum, aluminum sulfate） and modified polyferroaluminium, municipal out by chemical enhanced primary process, and a comparison of treating results was done. The effect of COD and phosphate removals was analysed. The experimental results showed that the modified polyferroaluminium dosing trace cation polymer had very good effect on enhanced primary process; in consideration of economy, the modified polyferroaluminium is a more practical coagulant.
