摘要
本文就污水除磷脱氮的方法进行了比较和经济技术分析。化学法在工艺上并不比生物法简单，而且运行费用及产泥量都很高，但其除磷效果优于现行的生物法；而对生物法活性污泥糖类物质进行控制则可从根本上解决生物法除磷效果不可靠的问题。因此糖控制技术使生物法成为一个经济高效的技术。
Concerning the economic feasibility, reliability and efficiency for phosphorus and nitrogen removal, chemical method was compared with - biological method in this paper. The advanced biological phosphorus removal technology by controlling sludge carbohydrate metabolism appeared to be a reliable, economical and very effective method for phosphorus/nitrogen removal, which is a prerequisite for eutrophication control.
