摘　　要：介绍了以黄河为水源的农村水厂净水构筑物及组合应用工程实例。黄河水泥沙含量较高,工程实例利用旋流斜管沉淀池进行预沉后,将絮凝、斜管沉淀、气浮、过滤4工序组合在一起,提高了净水效率,减小了占地面积,降低了工程投资,简化了管理程序。该工程技术在甘肃省获得应用,效果良好,在条件相似的地区具有推广应用前景。An actual case of the purification structure of the rural water supply plant based on the water source from the Yellow River and its combined application is described herein. The sediment content of the water from the yellow River is higher, for which the purification efficiency in this case is enhanced with the decrease of land occupancy, reduction of project investment and simplification of management procedures through the combination of 4 treatment processes such as floeeulation, inclined tube settlement, air flotation and filtration ＂alter the pre-settlement with vortex-inclined-tube sedimentation tank. This technology has been already applied within Gansu Province with a better effect, and then has a prospect to be popularized in the regions under the similar conditions.
