<p>PROBLEM TO BE SOLVED: To provide a transpiratory infiltration-type device for treating domestic waste water, etc., applying an artificial cultured microorganism as a tertiary water system which is not clogged and also used for transpiratory infiltration. SOLUTION: The domestic waste water W treated in a solid decomposing and settling tank 10 charged with a fungus as an artificial cultured microorganism and settling the solid contained in the waste water W and a tank 20 for oxidizing and decomposing the water W from the tank 10 by aeration is supplied to a transpiratory tertiary water tank 40 through a flow control tank 30. A water sprinkling mass 42, a cartridge-type filter medium 43, sawdust, porous ceramic, etc., are successively laminated in the tank 40, or the tank is formed with a mixed filter medium 44. A permeable partition wall 100 is provided around the tank and formed with a plate ceramic, etc., a pipe member 49 with the side wall pierced with many holes is set in the center, the waste water W supplied from the flow control tank is permeated and transpirated, and a requisite amt. or tertiary water is obtained.</p> |
