An integrated gravity-driven ecological bed for wastewater treatment in subtropical regions: Process design, performance analysis, and greenhouse gas emissions assessment

This study focused on the development of an integrated gravity-driven ecological bed (IGEB) for treating wastewater from agritainment activities in subtropical region. An integrated treatment process including multiple modules was designed. A filed scale treatment system was built and operated at an agritainment farm in Xiamen, China. Although the developed system had no requirement for electric power, it presented the good performances in …
