有很少的信息来描述生物过滤器如何生物和化学响应的动态负载的复杂混合物的污染物存在于自热嗜热好氧消化（ATAD）废气。本文介绍了一个全面的研究，这是在一个较长的项目，以评估使用生物过滤器处理ATAD废气的第一阶段的结果。在这项研究中，从位于俄勒冈州的ATAD系统的废气的组成和流量的特点。负载的还原硫化合物（RSC）和氨（NH3）到一个完整的规模的生物过滤器和这些化合物在处理后的空气中的浓度进行了测量，每小时的基础上为24小时的时间，这是ATAD系统的进料频率。从生物过滤器的渗滤液的特点是铵（NH 4+），硫酸盐（SO 42-），硝酸盐（NO3-），亚硝酸盐（NO2-）的浓度，使硫和氮的质量平衡，并确定生物降解过程中，活性。
There is little information to describe how a biofilter responds biologically and chemically to the dynamic loading of complex mixtures of contaminants that are present in autothermal thermophilic aerobic digestion (ATAD) offgases. This paper presents the results of a full-scale study that is the first stage in a longer project to evaluate the use of biofilters for treatment of ATAD offgases. In this study the composition and flow of offgases from an ATAD system located in McMinnville Oregon were characterized. The loading of reduced sulfur compounds (RSC) and ammonia (NH3) to a full-scale biofilter and the concentrations of these compounds in the treated air were measured on an hourly basis for a 24-h period, which was the feeding frequency for the ATAD system. The leachate from the biofilter was characterized for ammonium (NH4+), sulfate (SO42–), nitrate (NO3–), and nitrite (NO2–) concentrations to allow for mass balances on sulfur and nitrogen and to identify the biodegradation processes that were acti...
