BASIN OF VAPOTRANSPIRATION: TREATMENT OF DOMESTIC WASTEWATER AND FOOD PRODUCTIONS

Abstract. Currently, sanitation is a major concern of the world due to the problem caused by untreated wastewater. The objective of this study was to evaluate the potential of the basin evapotranspiration as proposing a constructive system of wastewater treatment and food production system by planting suitable to the rural, more specifically aimed at generating information on the structural system, the wastewater treatment, contamination and soil fertility inside and outside of the basin, as well as contamination of leaves and fruits planted system. If treating soil fertility basin for fruit such as bananas in the example of the basin under study, the results of analysis of soil showed a large increase in the parameters Ph, P, Ca, and K, evidencing the high fertility of the soil, but the need to correct the Ph by applying, for example, ammonium sulphate (NH₄) 2SO₄ and application of Zn, Fe, Mn, Cu and boron foliar to make the correction soil. In soil samples, as well as leaf and fruit planted system were not detected in the microbiological analysis the presence of total coliforms, coliform and Salmonella spp, being an indication for the use of the basin as a resource for the production of bananas as food .
