草甘膦废水回收草甘膦的方法研究

摘要

对草甘膦废水进行浓缩，然后加入生石灰等搅拌反应60min，过滤，滤饼加1∶1盐酸调节至pH=2.0，冷藏结晶。溶液过滤、水洗、烘干，得到草甘膦粉。草甘膦回收率达86%以上。%After concentration, the glyphosate wastewater reacted with quicklime for 60min. Hydrochloric acid was added into filter cake to make pH=2.0. The filtrate was crystallized by refrigerated overnight. After filtered, washing and drying, glyphosate powder was got. The glyphosate recovery was more than 85%.
