Selection of chemical phosphorus removal scheme based on Analytic Hierarchy Process

Chemical precipitation phosphorus removal process can improve the effect of sewage treatment system to meet increasingly stringent discharge standards. In order assist designers in selecting reasonable chemical schemes, analytic hierarchy was applied quantitatively evaluate each scheme from four aspects: water effect, operation cost, and management difficulty environmental impact. Finally, combined with an engineering example, quantitative evaluation method optimal are introduced, which provides a reference for selection engineering.
