Suzuki, T.(Nagano-ken. Research Inst. for Health and Pollution (Japan)) | Murakami, R. | Ishikawa, T.
A research on a treatment system of human excreta provided for the use in mountainous areas was carried out. The system was composed of two treatment processes, an anaerobic digestion and a seepage spray process. Vertical distributions of chemical components were observed in the anaerobic digestion tank, because the top of the tank was covered with water permeable phase and rain water was penetrated into the tank. Comparing the amount of inflow into and of evapotranspiration from the system, about 70% of the inflow was overflowed from the seepage spray tank, under the assumption that the whole rain water fallen on the system was permeated into it.
