改性沸石混合矿物对富营养化水质中磷的吸附性能研究

利用广东本地丰富的沸石矿产资源，组合比表面积大的矿物材料，经改性后，形成吸附和交换量大的混合矿物，对模拟富营化水质中的磷进行去除.结果表明，混合矿物脱磷效果显著，静态实验对含磷0.5mg/L的富营养化水中磷的去除率达95.07%；动态实验中，混合矿物对磷的吸附与流量有关，饱和吸附量为0.26～0.29 mg/g；并且对混合矿物的脱磷机理进行了探讨.

STUDY ON ADSORPTION PROPERTIES OF PHOSPHORUS FROM EUTROPHIC WATER BY MODIFIED ZEOLITE WITH OTHER MINERALS MIXED

Guangdong Province is rich in zeolite resource. Combined zeolite with other minerals of large specific surface, a modified zeolite with a high capacity of adsorption and ion exchange was made and was use to remove phosphorus from simulated eutrophic water. The experimental results showed that the dephosphorization effect was excellent, which removed phosphorus up to 95.07% from the water with 0.5 mg/L phosphorus in static tests. In dynamic experiments, the adsorption capacity of the mixed material was related to the flow amount of water and its content of phosphorus. The saturated adsorption capacity was 0.26 to 0.29 mg phosphorus per gram of the material. The experimental process and its results, as well as adsorption mechanism of the material, were also discussed in the paper.
