| 摘 要： | 采用底泥掩蔽技术，选取天然红土，添加适量的粉煤灰及石灰粉作为掩蔽覆盖物，对滇池富营养化水体进行现场修复实验。结果表明：用天然矿物材料减小底泥内源营养盐负荷的释放修复富营养化水体的效果良好；红土是有效的底泥覆盖材料，添加粉煤灰和石灰粉有助于消减底泥中TP、TN的释放量，还可提高对藻类等浮游植物繁殖的营养基础和对藻、藻细胞及其胚胎上浮生长的控制效率，最终达到除藻的目的，为滇池及类似湖库富营养化水体的修复提供了崭新的思路。 |

| Abstract: | In this paper, the polluted sediment capping technique was used to control the eutrophic water from the Dianchi Lake on the basis of field simulating experiments. The capping experimental materials include natural laterite and additives such as coal ash and powder of lime, which are all cheap geological materials. An analysis of the 125_day monitoring data consisting of the physical and chemistry indexes showed the eutrophication of the experimental barrel water and the interrelated water, it is held that the application of natural mineral materials to controlling the water eutrophication through the reduction of the internal pollutant loading of the polluted sediments in the eutrophic lake or reservoir is an effective technique, and that the laterite is an efficient superstratum for separating the polluted sediments from the upper eutrophic water. It is also considered that laterite plays an important role in reducing the release of the total phosphorus and the total nitrogen and increasing the controlling efficiency of the breeding and floating of the phytoplanktons such as alga, algae cells and algae embryos by means of the addition of the additives like coal ash and powder of lime. The algae may be eventually eliminated from the water. The technique can provide a new train of thought for the remedy of the eutrophic water in the Dianchi Lake and similar lakes. |
