摘要
将城镇污水处理厂深度除磷脱氮几种常用工艺进行优势比选,包括反硝化生物滤池、反硝化深床滤池、气浮、磁混凝高效沉淀池及其衍生的几种组合工艺,明确反硝化生物滤池脱氮+气浮除磷的组合工艺在处理效果、投资及成本方面均有明显优势。
This article compared several kinds of deep phosphorus&nitrogen removal processes in urban sewage treatment plant,include denitrifying biological filter,denitrifying deep bed filter,air flotation,magnetic coagulation high efficiency sedimentation tank and their combined processes,and discovered that the process of denitrifying biological filter+air flotation has obvious advantages in removal efficiency,investment and cost.
