<p>PROBLEM TO BE SOLVED: To provide a treating method of waste liquid capable of efficiently and inexpensively treating both organic solvents and phosphoric acids, in the treatment of the waste liquid containing organic solvents such as methanol and organic chlorine compounds and phosphoric acids. SOLUTION: In the treatment of the waste liquid discharged from a waste liquid discharge source 10 for discharging the waste liquid containing organic solvents and phosphoric acids, the methanol, etc., in the waste liquid are decomposed with bacteria in a first reaction tank such as a methanol decomposition tank 21 under an aerobic condition. Subsequently the primary treated liquid fed out from the methanol decomposition tank 21 is removed with at least one kind selected from bacteria and algae under an aerobic condition in a phosphoric acid removing tank 23.</p> |
