1、------------------摘要论文以陕西省岐山县蔡家坡镇排水规划为例,以新的科学理念,对城镇排水规划编制过程中一些通用的要点、工作以及遇到的排水问题进行归纳总结,加以分析探讨。本论文采用比例相关法预测规划期污水量,合理划分镇区污水排水分区,确定污水比流量,对污水干管的布置和管材的选择提出经济合理的方案。完成大量污水管道的水力计算。结合规划区实际情况,确定污水处理厂采用改进型Carrousel氧化沟工艺并提出扩建规模。论证了蔡家坡镇再生水回用的可行性,通过比选提出经济合理的再生水回用方案。通过对
2、国内外污泥处理技术的分析,结合规划区实际情况,分期确定污泥处置方案。在雨水管网系统规划方面,本论文分析了镇区易涝区改造的可行性,并遵循“自排为主、强排为辅,高水高排、低水低排,分散集水、就近排放”的原则,划分雨水系统分区并布置了雨水管网。分析了蔡家坡镇雨水资源化综合利用以及雨水系统管理规划的可行性。最后,论文对蔡家坡镇污水管网和雨水管网的分期建设提出设想,估算了相应的工程投资,并对城镇排水规划的成果进行了展望与分析。关键词:蔡家坡镇;排水规划;污水管网;雨水管网;工程投资II-----------Abs
