摘　　要：草甘膦为孟山都开发的一类广谱触杀型除草剂,主要有甘氨酸法和IDA法2种生产工艺,其中甘氨酸法是我国自主发展的主流生产工艺。基于C、P、N 3种主要元素的有效利用率、含磷母液量、副产物资源化利用水平等指标,综合分析了甘氨酸工艺现有生产水平、三废及其治理方法和技术进展。Glyphosate is a broad-spectrum systemic herbicide developed in 1970s by Monsanto. Two major synthesis pathways exist. IDA pathway features the intermediate iminodiacetic acid, and glycine pathway is invented independently and adopted dominantly by domestic manufacturers. In this paper, the production level of glyphosate, the generation and control of the three wastes were discussed based on the utilization of C, P and N elements, the amount of phosphorus-containing mother liquor, and the recycling of byproducts.
