| 摘 要： | 研究了活性氧化镁吸附剂对污水中富营养化元素磷的去除性能；并根据其吸附等温线估算了吸附热，发现磷酸根离子在氧化镁表面上主要是化学吸附；只有能在吸附剂表面发生特性吸附的共存离子才会对磷的吸附产生影响。

| Abstract: | The main work in this thesis is the adsorption performance of magnesium oxide absorbent in removing nourishing element phosphorus from wastewater. Adsorption heats are estimated on the basis of adsorption isotherm. From the results, we find that the adsorption of phosphorus (in the form of phosphate ion) on the surface of the adsorbent is chemisorption; experiments show that the co exist forgein cations in water would reduce the phosphate adsorption if they could be specifically adsorbed on the surface of adsorbent. |
