Thermodynamic Properties of Modified Sepiolite Phosphorus Removal

Abstract:

this thesis makes an in-depth study on the adsorption properties of modified sepiolite to phosphorus, and confirms how the factors such as, phosphorus wastewater flow, phosphorus removal agent dosage, temperature, additives and other factors effect on the phosphorus adsorption thermodynamic equilibrium of modified sepiolite. With the increase of phosphorus removal agent of modified sepiolite, adsorption capacity of modified sepiolite phosphorus removal to PO₄^3- ions in wastewater decreases; the removal rate increases with the increase removal agent; improving the acid modified temperature favors the adsorption of compound phosphorus removal to sepiolite; adsorption amount increases with the calcination temperature of sepiolite. This thesis describes the adsorption capacity of the modified sepiolite to phosphorus changes with temperature. According to the experimental data, adsorption isotherms at different temperature are presented in this thesis. And a theoretical foundation is provided for the industrial application of modified sepiolite phosphorus removal.
