摘要：分别在静态和动态两种条件下 ,以水葫芦为对象 ,对水生植物净化塘处理萘污水进行研究。结果表明 ,在静态试验中 ,水葫芦净化塘对浓度为 2 5、6 5和 16 1mg L萘污水的 7d净化率分别为 97 1%、93 7%和 90 4 %。动态试验中 ,相同浓度萘污水 7d后的出水净化效率分别为 99 2 %— 99 9%、97 3%— 98 6 %和 94 6 %— 96 7%。进水浓度分别为1 2mg L和 6 5mg L萘污水在水葫芦净化塘中的最佳停留时间分别为 5d和 7d 。
The Eichhornia crassipes solms ponds for purifying naphthalene contaminated water were studied under the conditions of static state and dynamic state. The results showed that Eichhornia crassipes solms ponds purified naphthalene contaminated water with efficiencies of 97 1%?93 7% and 90 4% respectively in static state experiment after seven days, which initial concentrations were 2 5 mg/L,6 5 mg/L and 16 1 mg/L, and the efficiencies of 99 2%-99 9%,97 3%-98 6% and 94 6%-96 7% respectively after seven days in dynamic state experiment The resident time of Eichhornia crassipes solms ponds were five days and seven days respectively, which input water concentrations were 1 2 mg/L and 6 5 mg/L The purification efficiencies of dynamic state was super than that of static state
