英文摘要	Water scarcity and the precariousness of municipal wastewater treatment, associated with high social vulnerability and resource shortages in Brazil's semi-arid regions, aggravate social disparities and make it impossible to improve the quality of life for the population living there. It is possible to reverse this scenario through the reuse of treated municipal wastewater in productive activities. This paper sets up a scenario with hydroponic cultivation, crop irrigation and fish farming using treated municipal wastewater as a mean of recovering water and nutrients, for food and income generation for the local families. Multicriteria decision analysis was applied to select a treatment system that would allow municipal wastewater reuse. A conventional preliminary treatment was used and, for the biological treatment, a Upflow anaerobic sludge blanket digestion (UASB) reactor was selected, which transforms the organic fraction of wastewater into biogas and sludge. When converted into electricity, biogas allows the meeting of the wastewater treatment plant demand and sludge could be applied to the soil as biofertiliser. Two post-treatments are presented: high-rate pond and constructed wetland. Both post treatments are adequate and provide treated municipal wastewater in a satisfactory condition for reuse. In addition, they produce biomass, which can be used as fish food. Water and nutrients are kept in a cycle, bringing socioeconomic benefits to the population and environmental benefits to the semi-arid regions.
