摘　　要：我国独立自主开发"中和料浆浓缩法磷铵工艺"的初期,针对该工艺的缺点曾有"酸耗高、设备生产强度低、能耗高"的观点。本文结合料浆法工艺20年来的技术进展,对这几个观点进行了客观的比较分析,得出了完全相反的结论。文中还对料浆法工艺的氟逸出和产品质量问题,提出了作者的看法。In the initial stage of the slurry concentrated process for ammonium phosphate developed independently in China, the process was reproached with 'high sulfuric acid consumption, low equipment production intensity and high energy consumption'. On summarizing and analyzing the technological advance of the process in the past 20 years, the above accusations are refuted. Also a few opinions on fluorine exhaust and product quality regarding the process are proposed.
