Treatment of faecal waste, without evacuation of effluents and without using flowing water, to reduce odor in periods when urine is not being evaporated

摘要

The waste treatment installation has a sealed pit (1) with a constant liquid (9) level (40), placed below toilet seats (6) and communicating through a vertical pipe (4) with its lower end immersed in the liquid forming a liquid trap to block odorous. The faeces collect at the bottom of the pit, while the urine flows (33) into an evaporation chamber (32) with a flue (33).
