| Abstract: | A simple method was developed for treating polluted scenic waters effectively.A zeolite bed was applied to degrade pollutants of eutrophication lake water.The result of test showed that natural zeolite could remove NH_4~+-N effectively with 95.0% removal efficiencies,and the removal efficiencies of COD_(Cr),TP and turbidity were 35.8%,(66.7%) and 78.0% respectively.The function mechanism between zeolite and NH_4~+-N were both ion exchange and nitrification reaction. |
