Process of treating glyphosate mother solution by catalytic air oxidation method

The invention relates to a glyphosate mother solution treatment process by means of a catalytic air oxidation method. Aiming to solve the problem of incomplete degradation of phosphorus-containing organics in treatment of a glyphosate mother solution by an oxidation method, the invention provides a process of treating a glyphosate mother solution by a catalytic air oxidation method. The process includes the steps of: first using a heat exchanger to heat the glyphosate mother solution to a temperature of 110-120DEG C, then bringing the glyphosate mother solution into a reactor in which a catalyst and a heating electric furnace are disposed, controlling the reaction temperature at 200-300DEG C, the reaction pressure at 5-9MPa, as well as the mother solution and air in a ratio of 1:120-200(g/l), carrying out reaction for 5-15min, then performing crystallization separation, and recycling the obtained phosphate and salt. The process has a low treatment cost, the oxidizing agent is clean, inexpensive, and easily available, and organics can be degraded more completely.
