Abstract
PURPOSE: To do away with drain or remarkably reduce the amount of water to be discharged, by separating the purified water of night soil, which is treated in a biological process and then precision-filtered, into permeated water to be used for miscellaneous affairs and concentrated water in a reverse osmosis method, and separating inorganic salts from the concentrated water.
CONSTITUTION: After solid matters, etc. are removed from night soil, the night soil is subjected to aerobic biological treatment, e.g. an active sludge process or a catalytic oxidation process, by diluting the night soil 5W20 times while aerating it. The biologically purified water is then precision-filtered by a filtering method using the filter of fiber bands and adapting capillarity. Thereafter, the water is treated in a reverse osmosis device provided with a reverse osmosis module comprising the high molecular membrane or the like of polyamide or the like, and separated into permeating water and inorganic salt-concentrated water. The permeated water is used as such for various uses, e.g. as diluting water in the biological treatment. The inorganic salt-concentrated water is further subjected to electrolysis or the like to remove BOD components, and then drained.
