污水规划中采用差异化用水量指标预测城市污水排放量

Application of Different Water Consumption Index to Forecast Urban Sewage Discharge in Sewage Planning

城市污水排放量预测是污水系统进行规划、设计、运行和管理所需要做的基础工作,科学、合理的预测污水排放量对污水处理厂、排水管网的建设规划意义重大。根据青岛市用水排水实际情况,在不同的污水量预测方法中,采用差异化用水量指标计算各污水系统的污水量;并分析污水量预测结果产生差异的原因。以期为类似城市的污水量预测提供参考。

The forecast of urban sewage discharge is the basic work required for the planning,design,operation and management of sewage system.It is very significant to scientifically and reasonably forecast the sewage discharge for the construction planning of wastewater treatment plant and drainage pipeline network.Based on the practical situation of water supply and drainage in Qingdao,the article uses the different water consumption index to calculate the sewage flow of each sewage system in the different sewage flow forecast methods,and analyzes the causes of the difference from the forecast result of sewage flow so as to provide the reference for the forecast of sewage flow in the similar cities.
