废物分解过程会释放气味、空气中的颗粒和生物气溶胶；因此，堆肥设施的空气质量控制对于工人的健康和堆肥设施的有效运行非常重要。由于介质阻挡放电 (DBD) 会产生化学物质，因此它已被用来去除对环境应用感兴趣的不需要的物质。在这项研究中，DBD 反应器被应用于堆肥设施，以同时去除气味、空气中的颗粒和生物气溶胶。当污染物气体流量为0.2 L、氨、胺、空气颗粒物和生物气溶胶浓度分别为150（或75）ppm、140 ppm、2.1×10(8)颗粒/m(3)和1.1×10(4)CFU/m(3)时，所需功耗低于18.9W。空气中污染物的去除效率随着比能量密度 (SED) 的增加而提高，其中氨和胺的去除效率高达 80% 和 76%。此外，当使用113 J/L的SED时，总体空气颗粒物的去除效率为75%，而当使用38 J/L的SED时，生物气溶胶的去除效率为89%。 (C) 2010 Elsevier B.V. 保留所有权利。
The process of waste decomposition releases odors, airborne particles, and bioaerosols; therefore, air quality control at composting facilities is very important to the health of workers and the effective operation of such facilities. Because dielectric barrier discharge (DBD) produces chemical species, it has been used to remove undesired species interesting for environmental applications. In this study, a DBD reactor was applied to a composting facility to simultaneously remove odors, airborne particles and bioaerosols. The power consumption required was below 18.9W when the flow volume of the pollutant gas was 0.2 L and the concentrations of ammonia, amines, airborne particles, and bioaerosols were 150 (or 75) ppm, 140 ppm, 2.1 x 10(8) particles/m(3), and 1.1 x 10(4) CFU/m(3), respectively. The removal efficiency of contaminants in the air increased as the specific energy densities (SED) increased, with removal efficiencies of up to 80% and 76% being achieved for ammonia and amines. Moreover, the removal efficiency of the overall airborne particles was 75% when 113 J/L of SED was employed, while the bioaerosols removal efficiency was 89% when 38 J/L of SED used.
