Clethodim waste salt resourceful treatment method

The invention belongs to the technical field of waste salt resourceful treatment, and particularly relates to a clethodim waste salt resourceful treatment method. According to the treatment method, a combined advanced oxidation mode is selectively adopted according to different total nitrogen and TOC indexes of inlet water, and when the C total nitrogen/CTOC value is 0-10, an electrocatalytic oxidation and deep denitrification combined process is adopted for treatment; when the C total nitrogen/CTOC value is 10-20, treating by adopting an ultraviolet light catalytic oxidation and deep denitrification combined process; and when the C total nitrogen/CTOC value is between 20 and 40, treating by adopting a combined process of ultraviolet light catalysis, electrocatalytic oxidation and deep denitrification. According to the treatment method provided by the invention, the detection index of the prepared brine is taken as a standard for measuring the high-grade oxidation difficulty level, and different high-grade ox
