Feasibility of a ‘greenhouse system’ for household greywater treatment in nomadic-cultured communities in peri-urban Ger areas of Ulaanbaatar, Mongolia: an approach to reduce greywater-borne hazards and vulnerability

摘要: Abstract There are limited studies that focus on greywater treatment and reuse options, particularly in nomadic societies with unique cultural climatic conditions. Studies relating to household nomadic-cultured limited. This study aims address this gap by examining a case high concentration of chemical components the (e.g. where oxygen demand ranged between 35 70,032 mg/L). Specifically, an upgraded greenhouse unit (GH-GWTU) was designed constructed during summer 2013 Ulaanbaatar, Mongolia, order assess technical feasibility, up-scaling capability, system at community level. Chemical biological test results indicated most parameters PO 4 3 − , NO 2 NH + ) had removal rate up 98%. Moreover, may extend period 8 months. has shown GH-GWTU is potential technology can significantly reduce chemicals agents Mongolian Ger contexts which greywater-borne hazards vulnerability area. It be replicable both scale according resources available for operation maintenance.
