Soil Filtration of Sewage Effluent of a Rural Area

摘要

The treatment performance of irrigation using primary lagoon treated municipal sewage is compared to normal stream or ditch water irrigation when applied to mountain meadows and crops in a high altitude climate during summer months. The two irrigation waters are applied at different rates to plots that have both natural drainage and tile underdrains. A special winter operation is evaluated for applying primary lagoon treated municipal wastewater to ridge and furrow basins after they have been covered with an insulating sheet of ice and snow. Development of winter operations allow capital cost of constructing winter storage to be drastically reduced for small rural treatment facilities.
