草甘膦废水预处理研究与工程应用

摘要

某草甘膦废水处理站已无法达到处理要求，需要进行改造.为了减轻后续的生化处理负荷,强化对草甘膦废水的除磷预处理,选用电絮凝氧化、Fenton氧化和电磁-Fenton氧化3种工艺作为草甘膦废水预处理工艺,进行了比选试验.试验结果表明,Fenton氧化为本工程的草甘膦废水最佳预处理工艺,可达到预期效果.%Some glyphosate wastewater treatment station could not meet the treatment requirements and needed to be upgraded. To reduce the biological treatment load of the following process, the dephosphorization - pretreatment process for glyphosate wastewater was enhanced. Three processes, including electric flocculation-oxidation, Fenton oxidation, and electromagnetism-Fen-ton oxidation were tested and studied to select the best pretreatment for glyphosate wastewater. The results showed: as the pretreatment for glyphosate wastewater in this project, Fenton oxidation could meet the expected standards.
