PROBLEM TO BE SOLVED: To provide a wastewater treatment method capable of preventing hydrogen peroxide from being left in the treatment of wastewater containing peracetic acid and hydrogen peroxide, and a wastewater treatment apparatus. SOLUTION: The wastewater treatment method is constituted so that the wastewater containing peracetic acid and hydrogen oxide is heated to a temperature higher than the normal temperature (slips S3 and S4), a neutralizing agent is added to the heated wastewater to neutralize the wastewater (steps S5 and S6) and hydrogen peroxide decomposition enzyme is subsequently added (step S9) to prevent hydrogen peroxide from being left.
