摘要
为保证城市污水处理效果,文章分析了污水处理工艺的选择原则和主要处理工艺的特点,并依托某城市污水处理厂,从碳源去除效果、脱氮、除磷效果、比能耗等方面对改进A/A/O工艺、氧化沟工艺、生物膜工艺、SBR工艺进行综合对比。同时,探讨了污水再生水在农田灌溉、城市服务、地下水回灌等方面的应用。
In order to ensure the effect of urban sewage treatment,the paper analyzes the selection principle of sewage treatment process and the working characteristics of main treatment processes,and the improved A/A/O process,oxidation ditch process,biofilm process and SBR process are comprehensively compared from the aspects of carbon source removal effect,nitrogen removal,phosphorus removal effect,specific energy consumption and so on.At the same time,the application of reclaimed water from sewage in farmland irrigation,urban service and groundwater recharge is discussed.
