Implementação de banheiro seco como proposta de saneamento ecológico

Abstract

The current research had the objective to implement a composting toilet of movable compartments, following the recommendations of Berger (2010). This technology of composting toilet is an alternative of ecological sanitation broadcast in several countries. Starting from the proposition of not using water in its system, the best way recommended to treat the human feces is the composting. In this way the composting toilet presented as a viable option, handling in the right way, it will be able to equate the problems of basic sanitation, especially in rural communities and small urban center where there is no sewage collector. Due to the technology of composting toilet been broadcast in the world, but little broadcast in Brazil it is necessary to have good knowledge about its operation, because if handles in the wrong way, it will cause harmful disease to the human health. So, it has been implanted in a rural property located in the city of Santa Helena, State of Parana, the technology of composting toilet of movable recipients, with the objective of analyze the availability of using the final compost as fertilizer in the agriculture thru composting. The final compost was separated in 16 experiments and subordinated to 4 different substratums. They are leftover, horse‟s dung, ash and urine. After 60 days of composting, they were separated in samples and analyzed in laboratory. The results showed that the process of composting has an important role at the efficiency to composting toilet in result of properties of the substratum. The parameter ph differed in relation to the others, because it presented significance of 5% by the test of Tuckey. Also, in relation to this result, the presence of thermo-tolerant coliforms what indicates that it is necessary more time of composting and reaches a higher temperature.
