摘要
为了研究现有的城市污水厂在《城镇污水处理厂污染物排放标准》(GB 18918—2002)一级A标准下,将原工艺进行升级改造以优化脱氮除磷效果的适用方法,结合了几个我国经改造处理效果改善明显的工程案例来进行讨论。在案例分析的基础上总结了各工艺在不同条件下的改造取向和注意问题。
In order to research how to upgrade the original process of existing municipal wastewater treatment plants to optimize the effect of nitrogen and phosphorus removal based on A standard of urban sewage treatment plant pollutant discharge standards（GB 18918-2002）,combined with several successful cases,applicable methods for upgrading reconstruction were discussed.Based on case analysis,transformation orientation and points for attention of various processes under different conditions were summed up.
