本文采用理论模型和曲线拟合相结合的方法，讨论了在固定床反应器中，活化剂浓度、FMP粒径、空间速度、时间、温度等因素对FMP溶解过程的影响，并在一些合理假设与简化的基础上建立了FMP溶解过程的动力学数学模型： 随机试验的误差检验结果表明：本文所建模型的计算值与实验值的误差小于12％，能够满足工业控制的需要。 本论文的研究，为开发以FMP为主要磷源的灌溉施肥专用复合肥料技术提供了理论依据。
In this paper, the effects on FMP dissolving from the concentration of activator solution, the diameter of FMP, the space velocity, the time and the temperature was discussed. And explicit mathematical models have been developed to predict and control the release rate of P2O5 from FMP. The kinetic model was given byyt=-6.09+214.80C0+18A9Rt-23.63C0Rt+5.65R03V0Rt-3 -6.22R03V0Rt-2 (4-6)Calculation and actual value were developed and compared with numerical solution for the concentration of P2O5. The results indicated that the error between calculation and actual value is no more than 12% and acceptable.This thesis provides a theoretical base for the developing of the technology for fertigation using Calcium-Magnesium Phosphate (FMP).
