摘要:
为了解决平原地区城市内河溶解氧过低问题,在数学模型推演的基础上,以常州市典型内河为例进行计算,比较调水增氧与曝气增氧的效果和成本差异,为投资与管理决策提供技术支撑。分析结果表明,在平原地区城市内河,调水增氧与曝气增氧的效果与成本主要受上游可调入河水溶解氧水平、河道自由流量、调水水泵动力效率、曝气设备增氧动力效率等因素影响。当上游河道溶解氧水平较高、河道自由流量较小时,调水增氧较为适宜,否则应考虑采取曝气增氧。在常州市内河河道,曝气增氧的溶解氧达标率、运行电耗和总体成本等指标均优于调水增氧,是更为适宜的河道增氧方式。
Abstract:
The low concentration of dissolved oxygen was a problem for most urban rivers in plain area. The effect and cost of oxygenation by watertransfer and aeration were compared based on mathematical models and data of a typical urban river in Changzhou city. The result will support the decisions of relevant investment and management. The effect and cost of urban river oxygenation in plain area were mainly influenced by the concentration of dissolved oxygenin upstream water, natural flow rate, power efficiency of water transfer and aeration. Water transfer was appropriate if dissolved oxygen was high in upstream water and the natural flow rate was low, otherwise aeration should be considered.Because of higher effect and lower cost of power and investment, aeration should be more appropriate for river oxygenation in this case study of a urban riverin Changzhou city.
