摘　　要：针对西北地区农业滴灌中河水泥沙含量高的问题,结合新疆玛纳斯河流域下游段泥沙资料及喷、滴灌灌区需水量的大小,分析了流量、河水浓度对浑水水力分离清水装置水沙分离效果的影响,对其首次应用于滴灌泥沙处理进行了试验研究。观测和分析各工况下进流量、进流浓度对溢流浓度、溢流中泥沙粒径分布及最大泥沙粒径和底孔浓度的影响规律。结果表明:浑水水力分离清水装置完全可以代替沉沙池加滤网的旧模式处理泥沙以满足滴灌用水的规范要求。Rivers In northwestern region have the characteristics of high sediment concentration,which limits the application of advanced water-saving irrigation technology.In order to solve the problems,based on the sediment data on down stream of Manas River in Xinjiang,and considered water requirements for sprinkler and drip irrigation,the experiment on dealing with the impact of discharge,water sediment concentration to the turbid water hydraulic separation device for drip irrigation has been done.In the course of experiment,the influence rules on inuput discharge,sediment concentration,sediment grain-size distribution as well as the maximum particle size and bottom flow density have been researched.The results indicate that the turbid water hydraulic separation device can definitely replace the settling basin with mesh to satisfy the drip irrigation requirement.
