摘要
以粉煤灰为主要原料，研究该吸附剂对景观水体中磷的去除效果，从废水pH值、振荡时间和灰水比三方面考察了对吸附作用的影响。结果表明，含磷废水经粉煤灰吸附处理12h后趋于稳定，达到吸附平衡，灰水比在1：10及pH值控制在8—9效果最好。在上述优化条件下应用于城区景观水体中磷的吸附处理，去除率为25．5％～42．2％。
In order to reduce the eutrophication, the removal rate of fly ash in processing phosphorus wastewater was discussed. The influences of dosing quantity, wastewater pH and oscillation time on the adsorption efficiency were analyzed. The results showed that the best oscillation time was 12 h, and the optimal dosing quantities of fly ash was 5 g, the best pH values was 8 - 9, and the coal ash to water ratio was 1 ： 10. Under the conditions mentioned above, the removal rate of phosphorus in urban landscape water by fly ash on can reach 25.5% -42. 2%.
