Abstract: The rapid aerobic stabilization treatment of aged waste is a biochemical process that involves injecting air and water into the landfill waste heap to activate the reactive activity of aerobic microbial communities, accelerate the degradation of organic components and achieve physical and chemical stabilization. Rapid aerobic stabilization plays an important role in aged waste restoration and treatment projects, whether as the main process of in-situ ecological restoration or as a pre-treatment process of ex situ restoration. The traditional aerobic stabilization equipment for the treatment of aged waste usually has disadvantages such as high civil foundation requirements, long installation and positioning cycles, and inconvenient transportation during transfer. In order to overcome these disadvantages and achieve functional requirements such as rapid installation, direct operation, overall transfer, and remote monitoring, based on the design concepts of modular, intelligent, integrated, and efficient, the improvement design and the engineering application of aerobic stabilization equipment was carried out, to achieve the goal of improving engineering efficiency and save engineering costs.

Key words: waste landfill site, aged waste, aerobic stabilization, pre-treatment, in-situ remediation, ex-situ remediation, equipment application
