摘　　要：化学沉淀除磷工艺能够提高污水处理系统的除磷效果以满足日益趋严的排放标准.为辅助设计人员选择合理的化学除磷方案,通过应用层次分析法从水处理效果、运行成本、运行管理难易程度和环境影响4个方面对各化学除磷方案进行了量化评估,最后结合工程算例介绍了层次分析法量化评估化学除磷方案的流程以及选择最优方案的方法,为工程中化学除磷方案的选择提供了参考.The chemical precipitation phosphorus removal process can improve the phosphorus removal efficiency of waste water treatment systems to meet increasingly stringent discharge standards.In order to assist designers in selecting a reasonable chemical phosphorus removal scheme,quantitative analysis of each chemical phosphorus removal scheme was carried out by applying AHP(analytic hierarchy process)from four aspects:water treatment effect,operation cost,management operation difficulty and environmental impact.Finally,the process of quantitative evaluation of chemical phosphorus removal scheme and the method of selecting the optimal scheme are introduced in combination with practical engineering examples,which provides a reference for the selection of chemical phosphorus removal scheme in engineering.
