背景技术 Background technique
随着我国城镇化进程加快、生态文明建设推进，为改善人居环境，市政公园及湿地公园建设数量不断增加，为满足市民亲水要求，景观人工湖建设已成为公园建设必不可少的重要景观元素。景观水体的来源主要是污水处理厂或再生水厂出水、河流或水库引水，但由于我国河流及水库受生活污水和工业废水污染严重，污水处理厂或再生水厂出水标准较低，入湖的景观水体水质几乎为劣Ⅴ类水质，容易造成景观水体发生富营养化，甚至导致水华现象发生，产生恶臭气味，严重影响市民的亲水性及休闲娱乐。目前，新建景观人工湖涉及入湖景观水体处理工艺，采用卵石净化层过滤水体，但并不能有效净化入湖水体、解决水质污染问题，还应不断创新此方面处理工艺，加强景观水体入水净化效果。 With the acceleration of my country's urbanization process and the promotion of ecological civilization construction, in order to improve the living environment, the number of municipal parks and wetland parks has continued to increase. In order to meet the citizens' water-friendly requirements, the construction of landscape artificial lakes has become an indispensable and important landscape for park construction. element. The sources of landscape water bodies are mainly water from sewage treatment plants or reclaimed water plants, and diversion from rivers or reservoirs. However, due to the serious pollution of domestic sewage and industrial wastewater in my country's rivers and reservoirs, the water standards of sewage treatment plants or reclaimed water plants are relatively low. The water quality is almost inferior to Class V water quality, which may easily cause eutrophication of the landscape water body, and even lead to algal blooms, resulting in foul smell, which seriously affects the hydrophilicity and leisure of citizens. At present, the newly built landscape artificial lake involves the treatment process of the landscape water entering the lake. The pebble purification layer is used to filter the water body, but it cannot effectively purify the water entering the lake and solve the problem of water quality pollution. It is necessary to continuously innovate this treatment process to strengthen the purification effect of the landscape water entering the water. .
现有入湖景观水体主要通过设置进水口卵石净化层，在主槽底部堆放粒径在15-35cm河卵石，起到过滤水体的作用，达到控制和减少入湖污染物的目的。但卵石的比表面积较相对较少，不易于微生物挂膜，不能够有效降解污染物。另外，半潜式人工生态滤床也是运用于浅窄型河道进行水处理，但其缺乏厌氧、好氧等工艺设置，不能够高效处理入湖水体。 The existing landscape water body entering the lake is mainly set up with a pebble purification layer at the water inlet, and river pebbles with a particle size of 15-35cm are stacked at the bottom of the main tank to filter the water body and achieve the purpose of controlling and reducing pollutants entering the lake. However, the specific surface area of pebbles is relatively small, and it is not easy for microorganisms to form a film, and cannot effectively degrade pollutants. In addition, the semi-submersible artificial ecological filter bed is also used in shallow and narrow rivers for water treatment, but it lacks anaerobic and aerobic process settings, and cannot efficiently treat the water entering the lake.
