【摘要】 水是人类生活和生产活动不可缺少、不可替代的宝贵资源，是社会可持续发展的重要因素，由于城市化、工业化和农业集约化的迅速发展，以及人类对水资源、水污染、污水再生与回用认识上存在一些误区，使得许多城市原有水资源不敷所用，许多地区进入环境的污染超过其环境容量，从而导致水体污染。加上对水污染的防治失调和对再生水未合理回用，最终引发城市水荒的加剧。而城市污水再生和再生回用，是解决水危机的有效途径之一。 本文以包头市北郊污水厂的污水资源化利用为研究对象，详细地阐述了水资源、水污染和水危机的重要性和严重性，污水回用的可行性和必要性。在收集了国内外有关污水回用方面的资料和当地的基础资料的前提下，通过对当地自然条件、气象条件、供排水现状的分析，对用水产用水量的调查，在水处理规模、进出水水质、水处理工艺选择等方面进行了论证，确定了水处理工艺流程和工程设计方案，并对项目作了比较科学的投资估算和经济效益、环境效益、社会效益分析，充分论证了项目的可行性。更多还原

【Abstract】 Water is the most valuable resource for human life and production, and is also the most important factor for continuous development of human society. But due to the rapid development of urbanization, industrialization and agricultural intensivism, furthermore, there are some misunderstandings in water resource, water pollution and wastewater recycle, water demand in many large cities is increasing, and can’t meet the requirements of the city development. Pollutions overload the environmental capability in many regions, so lead to the water pollution. In addition, because of the noneffective measures for preventing water pollution and unreasonable recycle of water, the lack of water becomes a severe problem for cities. One of the most effective ways to solve this problem is recycle and reuse of wastewater.This paper is focus on wastewater utility of Baotou Beijiao Wastewater Treatment Plant, describes the importance and severeness of water resource, water pollution and water crisis, besides, the feasibility and necessary of wastewater recycle. Collects a lot of information about wastewater recycle in China and foreign countries, as well as those information in Baotou City, not limited to the analysis of local natural condition, meteorological criteria and current water supply and water drainage, and also the investigation of water consumption, design the capacity of wastewater recycle and water quality. It is concluded that there are three main schemes of reuse water treatment methods - a. direct filter, b. micro flocculent filter and c. mixed sedimentation filter, the process adoption and project design scheme are determined with the consideration of technical and economical aspects. In addition, this paper estimates the investment, and analyze the economical benefits, environmental benefits and social benefits, which gives a full and careful analysis with anti-risk ability and demonstrating the feasibility and eagerness of project execution-更多还原
