江汉平原农村饮用水净化工艺研究

摘要

Aiming to the surface water pollution situation and drinking water-induced disease in rural area of Jianghan Plain, the rural water purification scheme and technology were designed to meet the basic drinking water demand of rural populations. The designed technology considered both the tight-structure demand of integrated equipment and the water purification function;the ozone pre-oxidation and coagulating sedimentation are selected as pre-treatment, the reliable quartz sand filtering are se-lected as regular treatment and the ultraviolet sterilization and membrane separation are chosen as advanced treatment. Based on the technical design of water treatment, a set of hydro -cyclone and enhanced coagulation equipment is designed, which in-tegrates mixing, flocculating and settling. As a modularization design, the water purification system is tight in structure, conven-ient in installation and use, and provides a new method for the purification of drinking water in rural areas.%针对江汉平原农村地表水污染情况和农村水生疾病的状况，设计了农村饮用水的净化方案与工艺，以满足农村居民的基本饮水需求。工艺设计兼顾了集成式装置对结构紧凑的要求和净化功能；预处理选用臭氧预氧化和混凝沉降进行，常规处理选用可靠的石英砂过滤，深度处理选用紫外线杀菌和膜分离。在水处理工艺的基础上，设计了一套集混合、絮凝、沉降于一体的旋流强化混凝设备。该水处理系统采用模块化组合，结构紧凑，安装、使用方便，为农村饮用水的净化提供了新的方法。
