| 摘 要： | 通过实验室小试 (2 0L)和滇池水体围栏扩大试验 (30 0m2 ) ,研究新型轻质除藻材料对滇池湖水中藻类的除藻及净化作用。小试结果表明 ,该除藻材料放入滇池水样实验 2 6d后 ,水质明显好转 ,藻类去除率可达 98% ,COD、TN及TP的去除率达到 38%～ 62 %。滇池湖边 30 0m2 水面围栏扩大试验结果显示 ,除藻材料放入试验区水体 1 0d后 ,水体中藻类含量明显减少 ,水体透光率从 55 %增加到 80 % ,水质状况也有很大改善。研究表明 ,该除藻材料是一种具有研究和应用价值的新型水体除藻材料。

| Abstract: | The experimental studies conducted at both bench-scale and in situ scale-up levels. The bench-scale study was with the lake water of 20 litre in the lab while the scale-up was conducted in an in situ enclosure with an area of 300 m~2 in Dianchi water body. The new light building algaecide materials tested have showed efficacies both for contaminants removal (i.e., COD, TN and TP) and algae removal. The enclosure experiment showed an evident decrease of algae concentration in the water after 10 days when the test materials were added. |
