5、业学院生物与化学工程系毕业论文地沟油的无害化处理工艺研究###摘要：地沟油，泛指在生活中存在的各类劣质油，长期食用可能会引发癌症，对人体的危害极大。由于存在不小的经济诱惑，仍有人铤而走险销售地沟油。针对民众反映强烈的地沟油问题，国务院办公厅2010年7月发布文件，决定组织开展地沟油等城市餐厨废弃物资源化利用和无害化处理试点工作。地沟油的主要化学成分是高级脂肪酸甘油脂，目前综合利用的基本原理是将地沟油催化分解为高级脂肪酸和甘油，再经过深加工成洗衣粉、皂粉、生物柴油、甘油等产品。地沟油的前处理无论将地沟油加工成何种产品，都必须经过前处理才适合进行深加工。前处理

6、工艺一般如下：地沟油粗油─离心过滤除杂─中温脱胶─中温碱炼─水洗─静置分层─干燥─精炼地沟油。。随着能源危机与环境恶化的不断加剧,寻找可再生、清洁的能源成为人类亟待解决的问题。生物柴油是一种以动植物油为原料,经过酯交换反应加工而成的脂肪酸低级醇酯类燃料。以餐饮废油为原料生产生物柴油,不仅减少了废油的存放量,实现了变废为宝,而且降低了生物柴油的成本。为此,对地沟油水解工艺及潲水油制备生物柴油工艺进行了探讨,旨在为废油的回收和资源再利用提供借鉴。StudyonharmlesstreatmenttechnologyofdrainageoilLiuYaxinAbs
