陕北地区农村污水处理适宜技术

Primary Disscusion on Rural Sewage Treatment Technology in Northern Shaanxi

伴随陕北经济的快速发展与城镇化水平的提高,水资源问题日益突出,陕北分散式农村污水的处理显得尤为重要。通过对陕北地区农村污水来源、水质特征、污水处理现状等进行分析,结合当地经济发展、自然环境、农业发展等因素,提出适宜陕北地区农村污水处理的生态沟和生态塘组合,厌氧沼气、人工湿地、RBC生物膜处理的四种高效节水技术,符合陕北地区农村污水处理中投资少、专业技术低、处理效率高等关键性要求,最终实现陕北地区水环境可持续发展。

With the development of economy and the improvement of urbanization level in northern shaanxi, water problem is more and more serious, and it is particularly important to treat decentralized rural sewage. Based on rural sewage sources, water quality and the situation of sewage treatment, this paper combined them with local economic development, natural conditions and agricultural development, and it put forward four suitable four rural sewage treatment technology, such as ecological ditch and ecological pond combination, anaerobic methane, artificial wetlands and RBC biofilm process, which meets the requirement of small investment, specialized technical problem,high efficiency. In the final, it can make contribution to sustain the balance of water environmental development in northern Shaanxi.
