Abstract:

Glyphosate, also known as N-(methyl phosphate)-glycine, is an organophosphorus pesticide with appreciable herbicidal activity. During its production process, a waste stream composed of complex components (glyphosate wastewater) is produced with the feature of abundant organic matter and high salinity, which obstructs the harmless treatment and resource utilization of glyphosate wastewater. In this paper, the principle and performance of several methods to treat glyphosate wastewater, such as incineration, advanced oxidation, adsorption, chemical precipitation, and membrane separation technology, are introduced, and their advantages and disadvantages are summarized. Incineration, advanced oxidation technology and biochemical treatment of glyphosate wastewater have low selectivity, which is not conducive to the resource utilization of glyphosate wastewater. In view of limited capacity of adsorption, developing the adsorbents possessing large adsorption capacity is urgently needed for the adsorption method in the industrial application of glyphosate waste treatment. chemical precipitation method exhibits excellent separation performance for the phosphate components even in the severe environment of high salt and high COD, whereas it produces a considerable amount of sludge with complex composition. Membrane separation method has been extensively applied to remove impurities in the waste stream and effectively recover valuable compositions, whereas the mere use of membrane technology could not meet the treatment demand due to the complexity of glyphosate wastewater. In this regard, new types of membrane technologies, such as liquid membrane separation and polymer inclusion membrane technology, have been developed. In terms of a variety of advantages including appreciable stability, longlifespan, easy operation and small footprint, the newly developed membrane separation technologies exhibit their prospectsingreen and economic treatment oforganic wastewater containing high salt and recycling of valuable composition.
