Abstract: The in-situ aerobic stabilization technology is one of pre-treatment processes toward middle-low intensity development of landfills. The landfill-gas system and liquid system design as its core technology are still weak on basic theories research and engineering application experience, the engineering application summary is not yet systematic. Therefore, the process design and engineering application of landfill-gas and liquid system of in-situ aerobic stabilization technology were systematically investigated, especially focused on process design methods and application practice of engineering cases of well network distribution, aeration and pumping volume calculation in gas system and leachate collection, recharge and treatment systems in liquid system. Finally, the existing problems were pointed out and the future development direction was prospected.

Key words: aged-refuse disposal, in-situ aerobic stabilization technology, gas system design, liquid system design, engineering utilization
