Glyphosate is an effective ingredient in many herbicides. The glyphosate wastewater discharged from many fine chemical plants contains high levels of chloride ions and phosphorus, and has a strong acidity (pH value of 1). Therefore, glyphosate wastewater has the characteristics of high concentration, high toxicity, and high salinity. Many of the components in its wastewater are non biodegradable, and the electrochemical oxidation method is costly and unable to recover glyphosate, resulting in resource waste. Membrane method, extraction method, distillation method and other methods can be used to treat glyphosate wastewater. Although glyphosate can be recovered, the purity of the recovered glyphosate is low and cannot create value for enterprises.
Our company has successfully developed a special organic phosphorus adsorbent and its supporting application process for wastewater containing about 1% glyphosate from a chemical plant. The recovery rate of glyphosate reaches 95%, and the purity of the recovered glyphosate is over 90%. The value of resource recovery far exceeds the cost of wastewater treatment.
