摘　　要：水利工程施工中的砂石筛分系统在清洗骨料的过程中会产生大量废水,若清洗后废水就地排放,将对生态系统造成不良影响,直接影响地表植被的生长,若流入河道,将无法保证鱼类正常生存,下渗土壤将对地下水质造成影响。结合新疆阿尔塔什水利枢纽工程施工经验,提出砂石筛分系统废水回收利用的环保措施,包括处理工艺、设计参数、处理设施尺寸及设备,实现砂石筛分废水再利用,缓解施工现场环境污染问题。The sand and stone screening system used for construction of water conservancy project renders large amount of wastewater in the process of cleaning aggregate.Direct discharge of the wastewater at site may lead to unfavorable impact on the eco-system and directly affect the growth of surface vegetation.If the wastewater flows into river,the normal survival of fish is unable to be ensured.Infiltration of wastewater into soil may affect the groundwater quality.Combined with the construction experience of Altash Water Conservancy Project in Xinjiang,the author presents the environmental protection measures of reusing wastewater from sand screening system and alleviating pollution at site,including the treatment process,design parameter,size and equipment of treatment facilities.
