摘要

本次设计是安徽省池州市排水工程设计，主要任务是完成雨、污水管网工程及污水处理厂工程设计。

现代城市规划中，给水排水的设计是一项十分重要的工作内容，它直接关系着居民的基本生活和城市的经济发展，对其起直接决定作用，也是城市建设水平的重要表征。在城市建设步伐日益加快的今天，为城市配置一套科学的给排水系统，实现水资源的可持续保障，无疑会增强城市的硬性投资条件，从而促进城市经济的可持续发展。因此，必须做好城市的排水工作，全方面促进可持续发展，进而促进社会的可持续发展。

如今水资源短缺已由原先的地区性开始向全国范围内蔓延，必须引起我们的高度重视。城市是人口高度密集的地区，城市用水量巨大，对城市水的管理显得尤为重要，所以必须加强对城市排水的建设与管理。

关键词：城市污水；排水；城市管理

Abstract

This project is a design for sewerage engineering of Chizhou City,Anhui Province, the major task is complete the design of rainwater and wastewater pipe and wastewater treatment plant.

The importance of urban drainage system Modern urban planning, water supply and drainage design is a very important work content, it is directly related with people's basic living, and economic development of the city, the direct decision role, is also an important characterization of urban construction level. In the quickening pace of urban construction today, for the urban configuration a set of scientific system of water supply and drainage, water resource sustainable security, will definitely strengthen the city's hard investment conditions, so as to promote the sustainable development of urban economy. So we must do a good job in the city's drainage at all levels, and promote the sustainable development and promote the sustainable development of the society.

Now water shortage has increased from regional began to spread across the country, must cause our attaches great importance to. City is a highly populated area, urban water consumption is huge, the management of urban water is particularly important, so must strengthen the construction and management of urban drainage. Key Words: Municipal sewerage; drain away water; city manageme
