曝气生物滤池设计与施工的若干问题

Problems on the Design and Construction of Aerated Biofilter

曝气生物滤池是一种新型的水处理工艺,兼具生物膜法和活性污泥法的许多优点。结合工程实践,从主要参数、池型选择、滤板滤梁、滤头与开孔率、承托层、空气压缩系统、滤头防堵、土建质量、空气管道吹扫以及调试等方面讨论了污水处理上向流曝气生物滤池(UBAF)设计与施工过程应注意的问题。

Aerated biofilter is a new water treatment process with many advantages that both biofilm process and activated sludge process have. Based on the engineering practice, the issues for attention during the design and construction of upflow biological aerated filter for wastewater treatment were discussed from the following points： key parameters, basin type selection, filter plate and supporter, filter underdrain nozzle and its porosity, supporting layer, air compressor system, anti-clogging of filter underdrain nozzle, quality of civil construction, air conduit purge, commissioning, and so on.
