摘要
矿物材料的孔道包括晶体表面的微孔和晶体内的结构性孔道,其孔道效应主要有孔道分子筛效应、孔道离子筛效应和孔道离子交换效应等。矿物材料的表面效应主要是表面结构重组效应、表面荷电效应和表面吸附效应。利用矿物材料的孔道效应和表面效应,对污染水和劣质水通过孔道过滤作用、表面吸附作用、化学反应作用和离子交换作用等进行处理,可有效去除水中的重金属、有机物等,达到治理和改善水环境的目的。
The portholes of mineral materials include microhole on the crystal surface and structural porthole in the crystal body. The molecular sieve effect, ion sieve effect and ion exchange reaction of portholes are three major porthole effects of mineral materials. The surface effects of mineral materials include structural reorder effect, electric charge effect and adsorption effect. Using the porthole effect and surface effect of mineral materials, the pollutants of heavy metals, organic matter and ,others existed in the wastewater can be effectively removed by means of the filtration of portholes, the adsorption of surface, chemical reaction and ion-exchange reaction. Thus, the sewage and inferior water can be satisfactorily treated. So the objective of controlling water pollution and improving aquatic environment is successfully achieved.
