小城镇通常位于城乡结合部，起到连接城市和农村的桥梁作用，小城镇建设 是城乡一体化的核心。中国的小城镇建设工作已经取得了一些成果和经验，但是 由于小城镇建设初期大多数都是自发性的，缺乏统筹及规划，导致小城镇在发展 过程中遇到了很多问题。其中之一是在小城镇建设过程中，由于污水处理配套设 施建设未能引起足够的重视，导致小城镇建成后难以满足居民日常生活所需，或 城镇升级配套存在困难。 本文以天津市滨海新区中塘示范镇污水泵站项目的原始资料作为基础，同时 收集、整理国内外相关泵站的建设经验及信息，采用工程建设项目的可行性分析 法，结合中塘示范镇地域特点对污水泵站项目的建设环境、建设技术可行性、经 济合理性及项目风险进行分析。在对项目环境、项目选址、建设规模、建设内容 及条件、项目各项专业技术、节能环保、施工进度、招投标方式等内容进行研究 的基础上，对项目的经济合理性和项目收益风险进行评估，同时对项目的社会影 响力进行分析，为项目投融资决策提供依据以及支持。 研究发现，中塘示范镇污水泵站项目符合生态农业与经济发展的要求，该项 目与当地的自然环境与地理条件相互吻合，有利于建设具有代表性的小城镇，该 项目的研究结果对多业态聚集型小城镇的污水泵站建设具有一定的参考意义。 关键词：污水泵站；中塘示范镇；可行性研究；滨海新区；小城镇建设III ABSTRACT Small town in urban fringe area serves as bridge between urban and rural areas. Small town’s construction is core of urban-rural integration. It has gained some experience and achievements. However, small town has encountered lots of problems due to its spontaneity in early construction period, lack of coordination and planning. For example, sewage treatment facility has failed to afford residents' daily needs and it can be hardly upgraded after its completion because of less attention during construction. This study is based on raw data of sewage pumping station project in Zhongtang Demonstration Town, Binhai New Area, Tianjin. Meanwhile, related experience and information globally is collected and summarized to analyze feasibility according to its characteristics and environment to evaluate project risk. The economic rationality and project benefit risk of the project is evaluated on the basis of the research on project environment, project site selection, construction scale, content and conditions of construction, various professional technologies, energy conservation, environmental protection, construction progress, bidding methods and other aspects of the project. Furthermore, the social influence and economic influence of the project is also analyzed to provide evidence and support for project investment and financing decisions. The study proves that the project of sewage pumping station in Zhongtang satisfies requirements of ecological agriculture and economic development. It is in harmony with local environment and geographical conditions. Construction of representative small towns will benefit from the project in Zhongtang and the study will be a significant reference to construction of similar sewage pumping stations in small towns.
