摘　　要：为分析新疆呼图壁县工业园区供水工程首部圆中环沉沙排沙过滤池滤水槽的过滤性能,采用滤水槽物理模型,试验研究了断级配砂(砾)分层过滤技术在泥沙处理问题中的可行性。试验结果表明:在设计流量下,通过运用断级配砂(砾)分层滤水的方式能够更大范围地处理推移质、悬移质泥沙和少量悬浮物,过滤浑浊水获得清水并能排除泥沙;断级配砂(砾)分层过滤技术在泥沙处理过程中能够降低水体浑浊度,改善水质,基本能够满足一般工业用水和生活用水粗滤要求。In order to assess the filtration performance of circular central sand filter for sand discharging and desilting in water supply projects of industrial parks in Hutubi County,physical experiments were conducted to investigate the feasibility of the fault diameter sand reverse stratified filtration technology in sediment treatment.The results show that the bed-load,suspended load,and a few floats in a larger area can be processed,and the turbid water can be cleaned by using this technology under a design flow.The technology is proved to be able to reduce the turbidity of the water body,improve the water quality and meet the needs for the industrial and domestic water consumption.
