Suberitical water oxidation coupled with membrane, crystallization and other technical units were used to treat glyphosate wastewater. Compared with traditional treatment processes, this new treatment process has high efficiency, produces no secondary pollutants, and recovers valuable by-products. A glyphosate enterprise used this process to treat 1 800 m3/d glyphosate wastewater. The operation results shows that the overall process is stable, and the salt can be recycled as a resource. The COD removal rate is over 93%, and the phosphorus recovery rate reaches 99%. The treated wastewater can enter a biochemical system to meet the relevant standards and discharged finally. The operating cost of the project is 177.3 yuan/t. Considering the phosphorus recovery value which is 467.2 yuan/t, the treatment process can increase the income by 289.9 yuan/t, which proves that treating the glyphosate wastewater with subcritical water oxidation technology has significant economic and environmental benefits.
