污泥好氧发酵过程中挥发性有机物（VOCs）污染风险研究
Contamination risk of volatile organic compounds during sludge composting
摘要
Abstract
Volatile organic compounds (VOCs) produced during sewage sludge aerobic composting is becoming an important secondary pollutant. The GC/MS method was used to analyze the components of VOCs at different positions in a Sludge Treatment Plant. A total of 19 VOCs were emitted during sewage sludge composting process. The main odor components, such as methanethiol, dimethyl sulfide and sulfide, have higher concentration than olfactory threshold at all four of the gas recovery points, and can do great harm to human beings. The concentration of total volatile organic compounds (TVOC) was 47.21 mg·m-3 inside the composting pile, and decreased to 1.73 mg·m-3 by a percentage of 96.3% after the emission to working area. Using the method of Maximum Incremental Reactivity to research the reactivity and Ozone Formation Potential of VOCs. VOCs components, such as alkanes, aromatic hydrocarbons, ketones, and olefin, have higher maximum ozone formation potential value, 1-butene and propylene have the maximum OFP, which were 947.70 μg·m-3 and 875.67 μg·m-3, respectively. Methyl mercaptan was an appropriate indicator to evaluate the emission of VOCs after a correlation analysis. The concentration of Methyl mercaptan in the researched plant was 0.04 mg·m-3, which was far lower than the limit of 2.5 mg·m-3 in GBZ 2-2002.关键词
