摘要
建立排水管网模拟模型是城市排水实现科学化管理的一个重要手段。作为污水管网建模的基础部分,研究了污水管网节点平均流量估算的间接求解方法,即根据用水量推求污水量。该法包括污水排放系数的确定和节点服务区域属性值的计算两部分。污水排放系数根据生活用水量结构确定;在城市排水管网GIS平台上可以估算节点服务区域属性,如人口、面积(平面面积和建筑面积)等。
Modeling of urban wastewater drainage network is an important tool for scientific
management. Now an indirect computation to estimate the average nodal wastewater flow of urban
wastewater network from the record of water consumption is presented, which is the base of the sewer
notwork model. This computation is based on two fundamental presumptions: wastewater discharge
coefficient and the service or tributary area of each node in the sewer network. The former is derived
from the structure of water consumption and the later can be obtained on the GIS platform, such as
populations, area (including plane and architecture area).
