摘要
骆马湖"九五"期间的氮磷平衡分析结果表明:氮磷在骆马湖湖体中的滞留量分别为1188 89t/a和193 36t/a。根据骆马湖的水质要求,在骆马湖截污工程完成后,没有新的污染进入水体的前提下,对骆马湖水体通过自然净化恢复到要求状态所需的时间进行了详细的数学推导和科学论证,结果表明,在不考虑底泥营养物质的情况下,只需0 19年左右的时间就能恢复,如果考虑底泥的影响,也只需0 59年左右的时间就能恢复。因此得出结论:对骆马湖实施截污是加速骆马湖水体改善的最佳途径。
The nutrients balance results of the Louma lake show that the N deposits is 1188.89t/a and the P deposits 193.36t/a.According to the demand of the water quality the detail deduce and scientific demonstration of the restoring rate of the Louma lake with the natural purification is conducted by authors in the premise that no new pollutants get into the restoration by the nutrients substance outputting without regarding of the substrate sludge.But once regarding of the releasing of the nutrient substance deposited in the substrate sludge for several decades and the output by water usage,it should be necessary to engineer pollution-cutting in order to accelerate the improvement of the water quality.
