摘　　要：常规水利水电施工污染水体泥水同步净化多采用直接曝气技术,利用已有建筑就地处理污水实现水体泥水同步净化技术。但由于缺少对水体污染负荷的估算,导致净化后的上覆水浊度较高,净化效果不理想。为此,提出水利水电工程施工期污染水体泥水同步净化技术。通过提高底泥的再悬浮能力与水体自净能力,实现污染水体泥水的同步净化。以甘肃中部生态移民扶贫开发供水工程为研究背景,对此工程施工期间的污染水体泥水进行同步净化,结果显示,应用所提技术净化后的上覆水浊度较低,净化效果较好。Conventional water conservancy and hydropower construction often uses direct aeration technology for synchronous purification of polluted water bodies and sludge,utilizing existing buildings to treat wastewater on-site to achieve synchronous purification of water bodies and sludge.However,due to the lack of estimation of water pollution load,the turbidity of the purified overlying water is high,and the purification effect is not ideal.Therefore,a synchronous purification technology for polluted water bodies and muddy water during the construction period of water conservancy and hydropower projects is proposed.By improving the resuspension ability of sediment and the self purification ability of water,synchronous purification of polluted water sludge can be achieved.Taking the ecological migration poverty alleviation and development water supply project in central Gansu as the research background,the polluted water and muddy water during the construction period of this project were synchronously purified.The results showed that the turbidity of the overlying water purified by the proposed technology was low,and the purification effect was good.
