摘　　要：采用二氧化碳产生法测定了水成膜泡沫灭火剂的28d生物降解性能,考察抑菌剂甲醛及灭火剂浓度对水成膜泡沫灭火剂生物降解率的影响。试验结果表明,添加甲醛及在一定范围内改变灭火剂浓度均不会影响水成膜泡沫灭火剂的生物降解率。从灭火剂组成成分角度分析了尽管含有难降解的氟碳表面活性剂,但水成膜泡沫灭火剂整体表现出易于生物降解的原因。The 28- day biodegradability of aqueous film-forming foam extinguishing agent （AFFF） was researched using CO2 evolution method. The influence of added formaldehyde and the concentration of AFFF on the biodegradation were evaluated. Results indicated that formaldehyde in AFFF and the change of test sample concentration did not affect the biodegradation of AFFF. Although containing difficultly biodegradable fluorocarbon surfactant, the AFFF products as a whole are highly biode- gradable.
