The invention provides a treatment method for improving the biodegradability of refractory organic wastewater, which belongs to the field of environmental protection. The method includes the following steps: placing organic waste water in a reactor, adding an oxidant, and performing a reaction at a temperature of 150-300° C. and a pressure of 2-6 MPa to obtain the treated organic waste water. The method can efficiently degrade nitrate nitrogen and other organic pollutants in the organic wastewater by heating and pressurizing, and the treated organic wastewater can be subjected to ordinary biochemical treatment to achieve deep removal of various pollutants and achieve the purpose of discharge. High efficiency, energy saving, economical and reliable features. |
