不同粒径泥沙解吸重金属污染物静态试验研究
Experimental Research on Heavy Metal Desorption for Sediment with Different Grain Size
【摘要】 从吸附反应动力学方程和质量守恒方程出发,导得静态解吸试验中泥沙剩余吸附量和水相重金属浓度随时间变化的计算公式,并导得泥沙剩余平衡吸附量和水相平衡浓度随泥沙吸附-解吸的特性、泥沙初始重金属吸附量(含量)和泥沙浓度变化的计算公式。在此基础上,结合试验进一步研究了不同粒径泥沙解吸重金属污染物的能力。
【Abstract】 Formulas of heavy metal residual adsorption content of sediment, and heavy metal concentration in water phase varying with time are derived in the laboratory experiment from the equation of adsorption dynamics and the conservation of mass. Furthermore, formulas used for calculating the residual equilibrium adsorption of sediment and the equilibrium concentration of heavy metal in water phase are obtained. On the basis of these, heavy metal desorption ability is studied by combining theoretical analysis and experimental research.
