| 中文摘要 |
| 采用人工介质富集微生物净化太湖梅梁湾水源地水体中的藻类.中试结果表明：随着介质密度和水力停留时间的增加,对藻类的去除率有所提高,增加水流速度并未降低对藻类的去除效果.当介质密度为26.8%、水力停留时间为5 d时,人工介质对藻类密度、生物量和叶绿素a的去除率分别为96.3%、88.7%、86.1%,表明人工介质对富营养化水体中藻类有较好地去除效果,同时对透明度和水下光照度也有明显的改善效果. |
| 英文摘要 |
| Pilot test was made on the removal algae in source water from Meiliang Bay in Taihu Lake through the use of enriched microbes by artificial medium. The results indicate that the algae removal efficiency enhances as the medium density and hydraulic retention time (HRT) increase. However the increasing of flow velocity doesn't reduce the algae removal effect. The removal rates of algae density, biomass, chlorophyll-a are 96.3%, 88.7%, 86.1% respectively when the medium density is 26.8% and HRT is 5d. It is evident that enriched microbes on the artificial medium can effectively remove the algae in the eutrophic lake. The transparence and intensity of illumination under water are improved obviously by artificial medium. |
