2、素等长期积蓄的底泥。其次在湖体内应用曝气 循环净化系统，主要可抑制微囊藻的增殖释放有毒物质。这次应用的主要工艺为生态 公园水培净化，净化效率高同时也降低了净化成本。 本设计计划在红枫湖设置 250 台潜流推流曝气机，在百花湖设置 63 台潜流推流 曝气机用于水湖底曝气循环净化， 预计有害藻类的去除率可达 86%。 在两湖修建的生 态公园预计净化效果： COD去除率达26% ， SS去除率达44% ， BOD去除率达38% ， TP、TN 去除率约达 20%。在两湖进行底泥疏挖，可有效的去除了底泥内的重金属元 素，并且防止它们向湖水上层扩散。 关键词关键词：湖泊富营养化；底泥疏挖；曝气；生态公园

3、修复 3 Ecological restoration management design scheme of a lake Abstract: in this paper, the design of the object is located in Guiyang city in guizhou red maple lake and lake flowers. Based on sediment pollution is serious, as well as sewage and industrial wastewater discharged into lake without dee

4、p processing of the rolls, nitrogen and phosphorus concentration is high, lead to lake and related government authorities in organizing basins centralized disposal of sewage discharged into the lake body again, investment vigorously construction of sewage treatment plants, to strict supervision, int

5、o more water could be truncated exogenous from the root. Firstly ,itPut forward by using the method of mechanicaldredge sediment removal of heavy metal elements such as long-term savings. Second application aeration in lake body circulation purification system, mainly inhibits the proliferation of m

6、icrocystis algae release toxic substances. The application of main technology for water purification ecological park, high purification efficiency of purification at the same time also reduces the cost. This design plan to set 250 units undercurrent push flow aerator in red maple lake, in setting 63 undercurrent push flow aerators baihua lake bottom is used for water circulation purification, expect harmful algae removal
