Abstract:were used to treat glyphosate wastewater. Compared with traditional treatment processes, this new treat⁃ment 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 op⁃eration results shows that the overall process is stable, and the salt can be recycled as a resource. TheCOD removal rate is over 93%, and the phosphorus recovery rate reaches 99%. The treated wastewatercan enter a biochemical system to meet the relevant standards and discharged finally. The operating costof the project is 177.3 yuan/t. Considering the phosphorus recovery value which is 467.2 yuan/t, thetreatment process can increase the income by 289.9 yuan/t, which proves that treating the glyphosatewastewater with subcritical water oxidation technology has significant economic and environmental bene⁃fits.
