摘要: 为实现湖库清淤底泥氟固化/稳定化,采用氢氧化钙、磷酸二氢钾、硫酸铁、氯化镁复配药剂体系,以含氟底泥的固化/稳定化效率为因变量,以氢氧化钙添加量、磷酸二氢钾添加量、硫酸铁添加量和氯化镁添加量为自变量进行了响应曲面法优化实验。结果表明,最佳固化/稳定化药剂配比为氢氧化钙3.572%、磷酸二氢钾4.342%、硫酸铁3.391%、氯化镁3.391%。在该条件下利用响应曲面法进行实验验证,清淤底泥中的氟固化/稳定化效率可达73.91%,与预测值(75.62%)吻合度高,表明模型可靠有效。

Abstract: In order to realize the fluoride solidification/stabilization of the lake and reservoir sediment, a compound of calcium hydroxide, potassium dihydrogen phosphate, iron sulfate and magnesium chloride was designed. Response surface methodology optimization experiments were conducted with the solidification/stabilization efficiency of fluorine-containing sediment as the dependent variable, and the calcium hydroxide addition, potassium dihydrogen phosphate addition, ferric sulfate and magnesium chloride addition as the independent variables. The results showed that the optimal solidification/stabilizing agent ratio was 3.572% calcium hydroxide, 4.342% potassium dihydrogen phosphate, 3.391% iron sulfate and 3.391% magnesium chloride. Using the optimal conditions simulated by the response surface method, experimental verification showed that the fluorine solidification/stabilization efficiency in the dredging sediment can reach 73.91%. The predicted value of 75.62% is in good agreement, indicating that the model is reliable and effective.

Key words: fluorine, sediment, solidification/stabilization, optimization of pharmaceutical ratio, response surface method
