【摘要】：餐厨垃圾是城市有机垃圾中最重要的一种,包括家庭、学校、食堂及餐饮行业等产生的食物加工下脚料(厨余)和食用残余(泔脚)。其特点主要是含水量高,水份占到垃圾总量的80~90%;有机物高,油脂高,盐分高;易腐烂变质,易发酵,易发臭,易滋长寄生虫、卵及病原微生物和霉菌等有毒有害物质。2011年5月,青岛市被选为餐厨废弃物资源化利用和无害化处理第一批试点城市,建设餐厨废弃物资源化处置厂迫在眉睫,青岛十方生物能源有限公司负责承建青岛市餐厨垃圾处理厂项目。青岛餐厨垃圾处理项目从2012年10月开工建设,到2013年8月份建设完成。自2013年9月份进入调试运行,2014年10月1日,通过综合验收,正式进入商业运行。本文通过分析国内外餐厨垃圾处理现状,总结归纳目前常用的几个处理工艺。确定青岛市餐厨垃圾处理规模。通过对几种常用技术工艺原理研究,探讨各个工艺优缺点,相互对比借鉴,分析桻岛选择厌氧发酵工艺的原因,探讨提高目前技术的水平的方法。并结合工程实际分析青岛餐厨垃圾处理厂厌氧工艺各个工作流程,研究各个工艺阶段,探讨创新工艺改进手段。通过分析青岛餐厨垃圾处理厂的环境和生态现状,对产生的废水、废气、固体废弃物采取适当的污染防治措施。收运系统作为处理餐厨垃圾的保障系统,是整个餐厨垃圾资源化处理系统的重要环节,也是保证处理厂正常运行的关键。最后对桻岛餐厨垃圾行业管理提出意见和建议。
[Abstract]:Kitchen waste is one of the most important types of municipal organic waste, including food processing waste (kitchen waste) and food residue (slops) produced by family, school, canteen and catering industry. It is characterized by its high water content, which accounts for 80 / 90 of the total waste; high organic matter, high grease and high salt content; perishable, fermentable, smelly, parasitic, eggs and other toxic and harmful substances, such as pathogenic microorganisms and molds. In May 2011, Qingdao has been selected as the first batch of pilot cities for the utilization and harmless treatment of kitchen wastes. It is urgent to build a disposal plant for food wastes. Qingdao Shifang Bioenergy Co., Ltd. is responsible for the construction of the Qingdao Food and Kitchen waste disposal Plant Project. Qingdao food and kitchen waste disposal project from October 2012 construction to the completion of construction in August 2013. From September 2013 into commissioning, October 1, 2014, through comprehensive acceptance, formally into commercial operation. Based on the analysis of the current situation of domestic and foreign kitchen garbage treatment, this paper summarizes several commonly used treatment processes. Determine the scale of waste disposal of food and kitchen in Qingdao. Based on the study of the principle of several common technologies, the advantages and disadvantages of each process are discussed, and the reasons for selecting anaerobic fermentation process are analyzed, and the methods to improve the current technology level are discussed. Combined with the engineering practice, this paper analyzes each working process of anaerobic process in Qingdao restaurant garbage treatment plant, studies each process stage, and probes into the means of innovation of process improvement. Based on the analysis of the environment and ecological status of Qingdao restaurant garbage treatment plant, appropriate pollution prevention measures were taken for waste water, waste gas and solid waste. The collection and transportation system, as a guarantee system for the treatment of kitchen garbage, is an important link in the whole recycling system of kitchen garbage, and also the key to ensure the normal operation of the treatment plant. Finally, the paper puts forward some suggestions on the management of the waste industry.
