摘　　要：探讨分析了四种提高餐厨垃圾毛油提取率的方法,分别是:选择合适的预处理工艺、提高提油系统进料的温度、厌氧进水罐顶部富油层回流至前端二次提油、提油系统出水回流淋洗垃圾,举例论证了四种方法的可行性。最后重点介绍了综合应用以上方法成功提高毛油提取率的典型案例——绍兴餐厨垃圾处理项目(一期)。In this article,four methods for improving the extraction rate of crude oil were explored and analyzed,including selecting appropriate pre-treatment processes,increasing the feed temperature of the oil extraction system,extracting oil again from the oil-water mixture at the top of the anaerobic influent tank,rinsing food waste with the effluent from the oil extraction system.This article provided examples to demonstrate the feasibility of the above four methods.Finally,a typical case of successfully improving the extraction rate of crude oil through the comprehensive application of the above methods was highlighted:Shaoxing City Food Waste Treatment Project(Phase I).
