课程名称：公用事业-污水网络设计 课程概述：本课程主要关注污水网络的设计与建设，涵盖从输入布局到最终的布局计划、剖面、详图、工程量清单（BOQ）和计算表等多个方面。污水系统的主要作用包括改善环境、预防低洼地区的洪水、阻止污水滞留引发的病媒传播以及防止污水与淡水源的交叉污染。课程强调以下几点： 1. 避免污水对地下水质量的影响，通过减少污水渗漏以及土水与污水的相互渗透，从而形成一个循环。 2. 摆脱“污水系统必须是地下管道”的传统观念，探索通过灵活的逐步投资和建设，以优化区域覆盖，同时考虑可用的财务和人力资源。 课程内容包括： - 第一部分：设计流量的估算 - 第二部分：污水管道的类型与水力学 - 第三部分：污水网络的设计 - 第四部分：检修井的类型与施工 - 第五部分：污水管道的铺设、接头与施工 本课程旨在让学员掌握污水系统设计的基本原理和实际施工技术，以实现可持续的污水管理。
