摘要
污泥堆肥过程释放的恶臭气体已成为制约堆肥无害化生产的重要因素,其中挥发性有机物(VOCs)在臭味贡献中占了很大比重。VOCs主要包括含硫化合物、含氮化合物和挥发性脂肪酸,组分复杂且治理困难。影响VOCs排放的因素主要有通风策略、温度和pH值,其中通风策略是最重要的影响因素。针对VOCs的治理,比较了几种常见的VOCs终端控制技术,最后推荐采用生物滤池-热氧化法组合工艺。
Volatile organic compound produced during composting can obviously cause environmental pollution. VOCs contain sulfocompound,nitrogenous compounds and volatile fatty acid,whose consistent is extremly complex and hard to be treated.The major factors that affect emission of VOCs are aeration,temperature and pH,among which aeration is the most important factor. Several VOCs terminal controlling methods were compared,and biofilter-thermal oxidation is finally recommended for terminal control.
