摘要
介绍了化学强化除磷工艺及化学除磷絮凝剂,认为同步沉析是适合城市污水处理工艺且铁系絮凝剂在经济性和处理效果等方面均优于其他絮凝剂。通过实验比较了海绵铁、二价铁和三价铁的强化除磷效果,发现海绵铁的除磷效果优于亚铁盐和高铁盐,分析并提出海绵铁在化学强化除磷方面具有突出的优势,认为它是化学除磷絮凝剂发展的一种趋势。
The article introduces the chemical enhance edphosphorus removal process,and considers that the synchronization phosphorus removal process is fit for municipal waste water treatment process and the flocculant of iron is superior to other flocculant.It found that the phosphorous removing effect of sponge iron is better than the phosphorous removing effect of Fe（Ⅲ） or the phosphorous removing effect of Fe（Ⅱ） by the experiment.We also analyze and propose advantage in the chemical enhanced phosphorus removal process,and We consider the sponge iron will become a trend in chemical enhanced phosphorus removal process.
