| 摘 要： | 采用曝气和投加营养物 -葡萄糖相结合的水体强化净化技术 ,研究了其对某具体污染水体的净化效果 ,结果表明 ,在曝气和向水体投加葡萄糖时 ,水样的 COD、NH3- N和 TP浓度均明显下降 ,但其相应的去除率并不随葡萄糖投加量的加大而增大 ;在曝气条件下 ,当体系中葡萄糖投加量为 2 .0 mg/ L· d时 ,污染物的去除效果最佳 ,投加 7d后水样中 COD、NH3- N和 TP的去除率分别达到 2 2 .4%、5 6.0 %和 3 7.0 %。

Experimental Study on Intensified Purification for Polluted Water |
| |
| Abstract: | In this research,purification effects on polluted water was studied by intensified purification technologies combined aeration and adding nutriment as glucose into polluted water.It was shown that the concentration of COD、NH 3-N and TP was reduced obviously by aeration and adding glucose,while their removal efficiency for pollutants was not increased with dosage of glucose increased. With aeration and adding 2.0mg/L glucose per day,removal efficiency for COD、NH 3-N and TP was best and after 7 days ,the removal rate reached 22.4%、56.0% and 37.0% respectively. |
