关于建设铜陵市南部城区污水厂的初步分析
摘要
工业发展提高了我国的经济效益，然而也导致了水污染和环境污染的加剧，尤其是大量水污染的存在使得人们可用的水资源进一步减少。本文初步分析了在铜陵市南部城区建设污水处理厂的必要性，探讨了污水处理工艺的选择。本设计的主要内容包括设计规模的确定、工艺流程的确定、处理设施的计算、机械设备的选择、污水厂平面图的布置。污水经处理后水质达到《城镇污水处理厂污染物排放标准》(GB18918- 2002)一级A排放标准要求后排入长江水域。

Abstract
Industrial development has improved the economic benefits of our country, but it has also led to the aggravation of water pollution and environmental pollution, especially the existence of a large number of water pollution, which further reduces the available water resources. This paper analyzes the necessity of constructing sewage treatment plant in the south of Tongling City, and discusses the selection of sewage treatment process. The main contents of this design include the determination of design scale, the determination of technological process, the calculation of treatment facilities, the selection of mechanical equipment, and the layout of sewage plant plan. After treatment, the water quality of the treated sewage can meet the requirements of class a discharge standard of pollutants discharge standard for urban sewage treatment plants (GB18918-2002), and then it is discharged into the Yangtze River.
Key words: preliminary design; sewage treatment process; urban sewage
