Abstract

As a kind of magnesium rich material, magnesium olivine has been proved to be a kind of artificial wetland substrate, which has a good effect on phosphorus removal. Therefore, it selected firing of the magnesium olivine under the 800 , 1000 , 1600 as the research object. The characteristics of phosphorus removal were investigated and compared. The experimental results show that the adsorption isotherm equation of Langmuir can well describe the adsorption process of phosphate on the magnesium olivine at different temperatures. Its phosphate saturated adsorption capacity was 195.65mg•kg-1, 169.49 mg•kg-1 and 145.43 mg•kg-1. At the same time, all kinds of magnesium olivine phosphorus desorption degree is low. It is proved that the performance of the magnesium olivine with low temperature is better. It is more suitable to be used as artificial wetland substrate.
