1、毕业设计设计题目：某湖泊的生态修复治理设计方案姓名：学号：院（系）：专业：指导教师：23某湖泊的生态修复治理设计方案摘要：本文设计的对象是位于贵州省贵阳市的红枫湖和百花湖。针对两湖底泥污染严重，以及生活污水、工业废水未经深层处理就排入湖库内，导致湖库内氮、磷浓度高等问题，政府及相关部门组织实现流域内污水的集中处理再排入湖体，投资大力兴建污水处理厂，对排入两湖的水源进行严厉监管，才能从根本上截断外源。提出了首先运用机械疏挖的方法，清除重金属元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
2、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：湖泊富营养化；底泥疏挖；曝气；生态公园修复23EcologicalrestorationmanagementdesignschemeofalakeGuoli090204206(Thedepartmentofchemicalandenvironme
