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p H=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%.
