Provided is a wastewater treatment method that keepspredominant inside the biological treatment tank and makes it possible to improve the water quality of the treated water while suppressing the volume of sludge generated in association with wastewater treatment. A wastewater treatment method for purifying wastewater by microorganisms in a biological treatment tank wherein the wastewater is purified by causing a first microorganism belonging to the genusthat is + for nitric acid reduction and &#x2212; for starch decomposition and a second microorganism that is &#x2212; for nitric acid reduction and + for starch decomposition in testing of the physiological properties of microorganisms to be predominant inside the biological treatment tank.
