伴随着世界经济的快速发展,化工产品的规模和品种不断扩大,由此带来的各种环境问题日益突出。近几年来,臭气废气引发的各种纠纷和上访事件越来越多,致使工厂被迫停产,造成了严重的经济损失和社会影响。

恶臭气体的概念及危害

臭味概念

臭气是一种公害,既污染环境,又危害人类健康,因此,国外一些国家很早就开始了臭气的专门立法工作。早在20世纪70年代,日本等国家就进行了大量的研究工作。虽然我国于1993年颁布了《恶臭污染物排放标准》,但对其研究还不多见。目前,臭气污染已被众多国家列为仅次于噪音的七大公害之一。

分类和危害

臭气是一种漂浮在空气中的微细物质,目前人类所能察觉的臭气污染物有4000多种,其中以硫化氢、硫醇类、氨、甲基硫、甲醛、酚类等数十种对人体有害。近几年,因臭味引起的污染公害事件屡见不鲜,据报道,世界上臭味公害案件数量位居第二。

臭气污染是指一切刺激嗅觉器官,使人感到不愉快,并对生活环境造成破坏的气体物质。有很多物质可以产生恶臭气味,常见的有:含硫化合物有H2S,甲硫醇,乙硫醇,甲硫醚,乙硫醚。醛类含氧化合物中有甲醛、乙醛、丙烯醛;醇类有甲醇、异丁醇;酚类有邻甲酚、对甲酚、间甲酚;脂类有醋酸甲脂、醋酸乙脂、丙烯酸甲脂、丙烯酸酯、丙烯酸酯、甲基丙烯酸甲脂;氨、甲胺、三甲胺、二甲胺等。以上提到的臭味物质基本可分为三类:

含有硫酸盐的物质,主要是硫化氢,硫醇和硫醚;含氮碱性化合物,主要是氨,三甲胺,尿素,烟碱;中性化合物,代表不饱和脂肪酸及其氧化物和烃类。
