Ecological restoration method for artificial lake body
The invention discloses an ecological restoration method for an artificial lake body, which comprises the steps of S1, constructing a protection slope and a water blocking embankment, specifically, constructing a circle of protection slope made of concrete along a concave bank junction of the artificial lake body and a river bank, and constructing the water blocking embankment along the protection slope; S2, conducting bottom mud dredging, specifically, removing pollutants such as nutrient substances and heavy metal in lake bottom sediments through a mechanical means; S3, separating algae from suspended particles, arranging a treatment area, and realizing solid-liquid separation by adopting an air flotation process; S4, arranging polyurethane filler at the water outlet to play a role of intercepting and filtering; S5, diluting the concentration of pollutants, and filtering algae, tiny suspended particles, sludge and the like through a filler; S6, planting aquatic plants; and S7, putting microorganisms and fishes, controlling excessive propagation of algae in the lake water body, and repairing the water body landscape. According to the invention, the pollutant content of the artificial lake is reduced, plants are planted, microorganisms, fishes and benthic organisms are placed, breeding of algae can be avoided, and the artificial lake has the self-recovery capacity and the self-cleaning capacity.
本发明公开了一种人工湖体生态修复方法，包括以下步骤：S1.建设护坡和阻水堤，沿人工湖体与河岸的凹岸交界处，建设一圈混凝土材质的护坡，并沿护坡建设阻水堤；S2.底泥疏浚，利用机械手段去除湖底沉积物中的营养物质和重金属等污染物；S3.将藻类和悬浮颗粒分离，设置处理区，采用气浮工艺，实现固液分离；S4.在排水口设置聚氨酯填料，起到截流过滤作用；S5.稀释污染物浓度，通过填料过滤藻类、微小悬浮颗粒、淤泥等，S6.种植水生植物，S7.投放微生物和鱼类，控制湖泊水体中藻类过度繁殖，对水体景观进行修复。本发明降低人工湖污染物含量，种植植物，放置微生物、鱼类、底栖生物，可以避免藻类的繁殖，使人工湖具有自我恢复能力、自净能力。
