为了降低富营养化，实验中讨论了粉煤灰、活性炭两种吸附剂对人工配制的含磷废水的去除效果。从投药量、废水pH值以及振荡时间三个方面考察了对吸附作用的影响。实验结果显示：粉煤灰对磷的去除效果远比活性炭的好，而且还可达到以废治废的效果。粉煤灰、活性炭的最佳投药量分别为0．06g／ml、0．05g／ml；最佳pH值均为6；最佳振荡时间分别为5h、7h；在上述条件下，粉煤灰对磷的吸附率可达90．38％，而活性炭则为31．54％。

In order to reduce the eutrophication, this paper discussed the removal efficiencies of two adsorbents： fly ash and activated carbon in processing phosphorus wastewater. The influences of dosing quantity, wastewater pH and oscillation time on the adsorption efficiencies were analyzed. The results showed that the removal efficiency on phosphorus using fly ash was better than that of the activated carbon. In addition, using fly ash could make the most efficient use of wastes. The optimal dosing quantities of fly ash and activated carbon were 5g and 6g respeclLively; the best pH values for both were 6 and the best oscillation times were 5h and 7h, respectively. In the conditions mentioned above, the removal rate of fly ash on phosphorus can reach 90.38%, but the removal rate of activated carbon is 31.54%.
