摘　　要：采用Mg(OH)2吸附—沉降法处理南宁市赖氨酸厂草甘膦车间的工业废水,并从中提取高含量的CaCl2产品,同时讨论了各种因素对CaCl2产品性能的影响。实验结果表明,本方法具有工艺操作简便,成本低,生产效率高的特点,氯化钙产品性能达到工业要求。The wastewater of glyphosate was treated by process of Mg（OH）2 adsorption-settling, and the calcium chloride in the wastewater was recovered. The influence factors on the performance of calcium chloride were investigated. The results showed that this process had some advantages, such as simple operation, low cost and high production efficiency. The performance of calcium chloride was meet with the industrial standard.
