The presence of abundant zeolites in association with volcanic pumiceous materials in Tererife (Canary Islands) prompted us to study their properties as a water purifying bed for inorganic contaminants, pathogenic bacteria, and soluble organic matter. The experimental model used was a chemical percolation reactor with a constant flux of solution, where the fixation kinetics were studied by comparing the input and the output solutions. The ammonium and phosphate retention values found after 10 days of constant percolation were 70% and 14%, respectively. In addition, a high reduction of soluble organic matter was observed, as well as the total removal of the bacteria species studied. The N-P-K values of the soluble and exchangeable nutrients indicate the potential capacity of the bed as a slow-release fertilizer.
特内里费岛(加那利群岛)存在大量与火山浮石材料相关的沸石,这促使我们研究其作为无机污染物、致病细菌和可溶性有机物的水净化床的特性。所使用的实验模型是一个具有恒定溶液通量的化学渗滤反应器,通过比较输入和输出溶液来研究固定动力学。在恒定渗滤10天后,发现铵和磷酸盐的保留值分别为70%和14%。此外,观察到可溶性有机物大量减少,以及所研究的细菌种类被全部去除。可溶性和可交换养分的氮-磷-钾值表明该床作为缓释肥料的潜在能力。
