用自行设计的人工湿地模拟装置处理重度富营养化的东湖水,当湖水在系统中停留24h 后,藻类的去除率可高达99.53%,且种类数也大大减少,出水中一般只有5—8种小型藻类。无藻渣产生,不易堵塞。人工湿地对藻类的去除功能主要是机械滤过作用,但植物发达的根系和微生物的活动,对于维持人工湿地良好的孔隙度和透水性,保证该系统对藻类高而稳定的去除率,起着关键性的作用。 Using a self-designed artificial wetland simulation device to treat heavily eutrophic Donghu water, when the lake water stays in the system for 24 hours, the removal rate of algae can be as high as 99.53%, and the number of species is also greatly reduced, and there are only 5-8 species in the effluent. Small algae. No slag is produced and it is not easy to clog. The removal of algae by constructed wetlands is mainly mechanical filtration, but the development of plant-developed roots and microorganisms maintains the good porosity and water permeability of constructed wetlands and ensures that the system has a high and stable removal rate of algae. The key role.
