摘　　要：“南海Ⅰ号”沉船自2013年全面发掘以来,保护现场室内大气品质逐渐恶化,充斥着难闻的恶臭异味。检测分析发现,室内空气含有氮化物、硫化物等污染物,对船木标本进行的加速腐蚀实验,也显示出有含硫污染物的释放。“南海Ⅰ号”沉船保存区空气中的污染物及产生的恶臭异味,对“南海Ⅰ号”沉船的安全保存和工作环境造成了严重影响。本研究使用具备多孔结构的载体负载化学转化剂制备而成的化学干附滤媒,在吸附大气中含硫等污染物的同时,可将污染物分解、转化成无害的盐类,从而达到净化大气污染物的目的。经实验室及现场验证实验,化学干附滤媒净化的转化率高、净化过程持续性好,可以为现场环境治理方案设计提供切实可行的技术支撑。Since the full excavation of the“Nanhai I”Song Dynasty shipwrecks in 2013,the indoor air quality at the preservation site has gradually deteriorated,filled with an unpleasant odor.By testing and analysis,it was found that indoor air contains pollutants such as nitrogen compounds and sulfides.Accelerated corrosion experiments on wood specimens of the shipwrecks also showed the release of sulfur containing pollutants.The pollutants in the air and the odor generated in the preservation site area of the Nanhai I Song Dynasty Shipwrecks have had a serious impact on the safe preservation of the shipwrecks and working environment of the area.In this study,a carrier loaded chemical conversion agent with a porous structure is used to prepare a chemical filter medium for dry adsorption.While the filter medium adsorbing pollutants such as sulfur in the air,pollutants can be decomposed and converted into harmless salts,thereby achieving the goal of purifying air pollutants.Through laboratory and on-site verification experiments,it has been found that the conversion rate of chemical filter medium for dry adsorption purification is high,and the purification process is sustainable,which can provide practical technical support for the design of on-site environmental treatment plans.
