我国西部小城镇给水与污水处理技术需求分析

我国西部地区由于地域辽阔，自然地理环境复杂多样，经济发展水平落后，其城镇给水和污水处理工艺不能简单照搬国外或国内发达地区现有的成熟技术。在对西部30余个小城镇实地调研的基础上，结合西部小城镇社会经济状况和各地区自然环境特点，分析了西部小城镇对给水和污水处理设施的技术需求，并针对自然环境特征不同的地区提出了相对较为适宜的城镇给水和污水处理技术。

Analysis of Technical Requirement for Municipal Water and Wastewater Treatment in China's Western Small Towns

With a vast area,complex and varied geographical environment,lower economic development level,China's western areas have a special requirement for technologies of municipal water and wastewater treatment and can't copy existing mature technologies in developed countries and China's eastern areas.Based on a site-survey on more than 30 small towns in western China,combining the social and economic situation and the natural environmental characteristics,the technical requirements for water and wastewater facilities in these towns were analyzed,and feasible and cost-effective technologies of town water and wastewater treatment were presented for the regions with different natural environmental characteristics.
