流域水环境污染生态修复技术研究

Study on Ecological Restoration Technology of Water Environment Pollution in River Basin

随着城市化和工业化水平的提高,我国正面临着严重的生态环境问题,尤其是流域水污染问题。我国2021年环境状况调查数据基于高锰酸盐指数、污染物浓度、生化需氧量等指标,判定我国流域水环境污染严重,各水系均受到了不同程度的污染,并伴有富营养化。近年来,随着我国城市化进程的加快,城市用水的需求量不断上升。为了满足城市用水需求,需要引用流域的天然地表水资源,这就要求流域的水环境必须达到一定标准,然后才能用作城市水源。以往的流域水环境污染生态修复技术缺乏系统性,导致水环境污染修复效果不佳。因此,为了给居民提供健康的水资源和良好的流域水环境,本文对流域水环境污染生态修复技术进行了研究,并提出了相关建议。

With the improvement of urbanization and industrialization,China is facing serious ecological and environmental problems,especially water pollution in river basins.According to the survey data of China's environmental situation in 2021,based on indicators such as permanganate index,pollutant concentration,biochemical oxygen demand,etc.,it is judged that the water environment in China's river basins is seriously polluted,and all water systems are polluted to varying degrees,accompanied by eutrophication.In recent years,with the acceleration of urbanization in China,the demand for urban water is increasing.In order to meet the urban water demand,it is necessary to use the natural surface water resources of the basin,which requires that the water environment of the basin must reach a certain standard before it can be used as the urban water source of the basin.In the past,the ecological restoration technology of river basin water environment pollution lacked systematic ness,which led to poor restoration effect of water environment pollution.Therefore,in order to provide residents with healthy water resources and good watershed water environment,the ecological restoration technology of watershed water pollution was studied,and some suggestions were put forward.
