湿垃圾资源化处理工程实例分析与优化建议

Analysis and Optimization on an Example of the Wet Waste Recycling Treatment Project

松江湿垃圾资源化项目将餐厨垃圾和厨余垃圾合并处理,设计采用“预处理+湿式厌氧消化+沼气发电利用”组合工艺。工程调试运行期间,本研究对项目运行过程产生的各类衍生品的特性进行了测试分析,通过中试实验探索了厌氧沼渣资源化利用的可行性,并结合运行参数对各环节提出了工艺优化建议。

Songjiang Wet waste resource recovery project combines food waste and kitchen waste,and the combined process of “pretreatment + wet anaerobic digestion + biogas power generation” was adopted.While the project is running.In this study,the properties of various types of biogas residue derivatives were tested and analyzed during trail operation.The feasibility for the resources utilization of digestates was explored through pilot test,and the operating parameters of each process procedure were optimized.
