摘要：
论述了我国西部开发水的问题是一个关键问题,提出城市污水采用氧化塘(兼作蓄水塘)处理技术,具有兼顾污水处理与回用的需要;能大幅度降低工程投资与运行费用和合理控制城市水污染等优点。这一污水处理与回用技术对西部干旱缺水的城市和建制镇,实现利用污水资源,发展林业和污水土地深度处理,减免城市水污染将起到重要作用。研究表明,到2010年,当城市周边实现污水灌溉林农业的土地面积达到城区面积的2～4倍时,将有效促进干旱地区的生态林农业区开发,以及生态都市建设和城市化发展进程。

Abstract:
Water is the key point in the exploitation of Western China.The t reatment technology of o xidat ionpond(i t can also be used as impounding reservoir)can meet the need of sew age t reatment and w ater reuse.Thetechnology can reduce the project investments and the operation expenses remarkably,and it can cont rol municipalsew age pollution well.The eff luent can be reused w ell on developing forest ry,grassland and farming of westernarid regions.As researches show,before 2010,w hile the area of wastewater irrig ation in forest ry,g rasslandand agriculture amounting to 2 ～4 times than that of the city area,i t w ill accelerate the development of ecotypeforest ry-ag riculture zone,the building of eco-city,and the development process of urbanization ef ficiently.
