description PROBLEM TO BE SOLVED: To provide an anaerobic organism processing method and a device for organic waste liquid, by which recovery water with high water quality can be effectively obtained while preventing the clogging of a reverse osmosis membrane by effectively removing hydrogen sulfide in organism processing liquid by a simple device and operation for obtaining the recovery water with the high water quality by subjecting the organic waste liquid to anaerobic organism processing, filtering the filtrate through the membrane, and subjecting the filtrate to the reverse osmotic membrane processing.SOLUTION: The organic waste liquid is subjected to the anaerobic organism processing in the anaerobic processing device 1, the anaerobically processed liquid is subjected to solid/liquid separation by membrane filtering in the membrane filtering device 2 in an aerobic condition, the membrane filtered liquid is stored in an aeration device 3 while the membrane filtered liquid is kept in the anaerobic condition, the membrane filtered liquid is aerated with the gas not containing oxygen and hydrogen sulfide desulfurized in a desulfurizing device 6 to remove the hydrogen sulfide, the aerated liquid is subjected to the reverse osmosis membrane processing by supplying the same to a reverse osmosis membrane processing device 4, and the permeated liquid is recovered.
