Abstract:

The in-situ aerobic stabilization technology of landfills is one of pre-treatment processes toward middle-low intensity development. The landfill-gas system and liquid system design as its core technology is still weak on basic theories research and engineering application experience all over the world, the engineering application summary is not yet systematic. Therefore, we systematically investigated the process design and engineering application of landfill-gas and liquid system of in-situ aerobic stabilization technology, 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. This paper concluded by identifying current problems and making suggestions for future directions.
