城镇污水污泥协同处理厨余垃圾厌氧消化的标准化研究

Standardized Research on Anaerobic Digestion of Kitchen Waste in Co-treatment of Municipal Sewage Sludge

摘要:

在“双碳”背景下，城镇污水污泥与厨余垃圾协同厌氧消化得到广泛关注和工程化实施，在多地取得了良好效益。首先分析了我国典型协同厌氧消化工程的规模、进料配比、主要技术参数、产物资源化利用等内容，对比了现行污泥和厨余垃圾单独厌氧消化技术标准的主要内容，分析了现行标准对工程建设的指导性，提出亟需制定针对污泥协同处理厨余垃圾的厌氧消化技术标准，以指导工程建设。其次，对美国、欧洲等国家在协同厌氧消化工程建设情况、主要技术条件和产物处置标准等内容，进行了分析和总结，以期为协同厌氧消化相关标准制定提供参考。

Abstract:

Under the “dual-carbon” background, the co-anaerobic digestion of municipal sewage sludge and kitchen waste has received extensive attention and engineering implementation, and the good benefits have been achieved in many places. Firstly, the scale, feedstock ratio, main technical parameters, and product resource utilization of typical co-anaerobic digestion projects in China are analyzed. The main contents of the current technical standards for separate anaerobic digestion of sludge and kitchen waste are compared. The guidance of the current standards for engineering construction is analyzed. It is proposed that there is an urgent need to formulate the anaerobic digestion technology standards for the co-treatment of sludge and kitchen waste in order to guide the engineering construction. Secondly, the construction situation, main technical conditions and product disposal standards of co-anaerobic digestion projects in the United States and Europe are analyzed and summarized, which provides the references for the formulation of relevant standards for the co-anaerobic digestion.
