摘要
为减少污水排放量,降低污水对生态环境的破坏,缓解水资源供求矛盾,分析了几种主要的城市污水处理回用技术,即A-A-O工艺、SBR工艺、氧化沟工艺、深度处理回用工艺、曝气生物滤池工艺等。展望了我国城市污水处理回用的发展趋势:污水处理回用设备设施和技术不断更新升级,污水处理厂规模不断扩大,标准不断提高,监管力度不断增强。应重视城市污水处理回用,强化污水处理回用能力,加强对污水处理回用工艺及其组合应用的深入研究,加强对污水处理设备的改进,实现对城市污水的深度处理,为城市提供可靠稳定的补充水源。
In order to reduce sewage discharge,reduce the damage of sewage to the ecological environment and alleviate the contradiction between supply and demand of water resources,several main urban sewage treatment and reuse technologies are analyzed,namely A-A-O process,SBR process,oxidation ditch process,advanced treatment and reuse process,biological aerated filter process,etc.The development trend of urban sewage treatment and reuse in China is prospected,i.e.the equipment,facilities and technology of sewage treatment and reuse are continuously updated and upgraded,the scale of sewage treatment plant is continuously expanded,the standards are continuously improved,and the supervision is continuously strengthened.We should pay attention to urban sewage treatment and reuse,strengthen the capacity of sewage treatment and reuse,strengthen the in-depth research on sewage treatment and reuse process and its combined application,strengthen the improvement of sewage treatment equipment,realize the advanced treatment of urban sewage,and provide a reliable and stable supplementary water source for the city.
