Field experiments on treatment of human excreta were proceeded using FAT method designed for the use in the alpine zone. The experimental plant is consisted of three parts, that is, a filtration tank(2m3), a contact aeration tank(2m3) and trenches(39m). In this system, human excreata is treated by contact aeration process followed by gravity filtration. The secondary effluent is finally treated by land treatment process by the use of trenches depending on natural purifying ability of soil. Conclusions derived from the experiments can be summarized as follows.1) SS, BOD, COD, TN and TP contained in raw human excreta were removed about 90, 50, 60, 20 and 50% respectively, through the first treatment process (filtration).2) BOD, COD, TN and TP contained in the filtrate were removed about 98, 50, 40 and 10%, respectively, through the second treatment process (contact aeration).3) BOD, COD, TN and TP contained in secondary effluent were removed more than 94, 98, 97 and 99%, respectively, through the third treatment process (land application).4) Each of BOD, COD, TN and TP contained in raw human excreta was removeed more than 99% through the FAT method consisted of the three treament processes.
