摘　　要：随着城市化水平和居民对环境要求的提高,能与周边环境协调、封闭性强、无二次污染的地下式污水处理厂可能成为城镇污水处理厂的新发展趋势和发展方向。曝气生物滤池工艺因具有容积负荷大、水力负荷大、可通过增加填料高度来减少占地面积等特点,从而可以被应用于全地下式污水处理厂。通过假定设计条件,比较曝气生物滤池工艺、Bardenpho工艺、MBR工艺在占地、投资、运行上的区别,介绍曝气生物滤池的种类及设计要点,分析曝气生物滤池在全地下式污水处理厂运用中的优缺点。分析结果表明:对于地下式污水厂项目,曝气生物滤池是一种良好的选择,为地下式污水厂发展提供了新的方向。With the improvement of urbanization level and the increasing environmental requirements of residents,underground wastewater treatment plant that can coordinate with the surrounding environment,have strong closure,and no secondary pollution may become a new development trend and direction of urban sewage treatment plants.The biological aerated filter can be applied in underground wastewater treatment plants due to its characteristics of high volume load,high hydraulic load,and the ability to reduce land occupation by increasing the height of the filling material.By assuming the design conditions,the differences between the biological aerated filter process,the Bardenpho process and the MBR process in terms of land occupation,investment and operation are compared,the types and design points of the biological aerated filter are introduced,and the advantages and disadvantages of the biological aerated filter in the application of the underground wastewater treatment plant are analyzed.Analysis results surface:For underground wastewater treatment plant projects,the biological aerated filter is a good choice,which provides a new direction for the development of underground wastewater treatment plants.
