摘　　要：针对西气东输二线东段13B标段水资源匮乏的现状,探讨了利用灌溉区内高浊度黄河水作为水源的可行性工艺。高浊度黄河水处理试验采用聚氯化铝混凝沉淀强化工艺,对比分析了加入自然沉淀型聚氯化铝前后,不同沉淀时间的水质情况及沉淀水质的成分。结果表明:只有加入自然沉淀型聚氯化铝沉淀2h后的水质能够满足西气东输二线的试压用水要求;不加入任何沉淀药剂,仅依靠自然沉降3h,无法满足要求。依据试验结果,制定了利用高浊度黄河水作为试压用水的工艺流程,解决了水资源匮乏地区试压用水的施工难题。In view of current water resource shortage in the eastern 13B pipe section of the 2nd West-to-East Gas Transmission Project, the feasible process of using the high-turbidity Yellow River water in the irrigation area as a water source is discussed. Polyalurninium chloride coagulation sedimentation strengthening process is used for the high-turbidity Yellow River water treatment test and a comparative analysis is made for water quality and sediment ingredients in different sedimentation times before and after adding natural sedimentation types of polyaluminium chloride. The results show that the water can meet the requirements for hydrotest water for the pipeline adding natural sedimentation polyaluminium chloride and holding sedimentation for two hours, and the water quality without adding any sedimentation agents but only with natural sedimentation for three hours cannot meet the requirements. In accordance with the test result, the process of using the high-turbidity Yellow River water as hydrotest water is developed to solve the construction problem of hydrotest water in water resource shortage areas. （1 Table, 3 Figures, 4 References）
