Abstract
The glyphosate mother liquor wastewater can be treated to achieve degradation of wastewater COD and organic phosphorus into orthophosphate. The glyphosate mother liquor wastewater was treated by catalytic wet oxidation technology and the effects of different process conditions on the degradation of COD and the formation of phosphate were investigated. When the experiment of 88000 mg/L COD concentration, 537 K reaction temperature, 2 h residence time, 30 mL glyphosate mother liquor, 20 mL H2O2 and 0.15 g CuO catalyst dosage was carried out, the removal ratio of COD and phosphate production ratio could reach 94.5 and 93.4 %, respectively.
