真空排污系统参数分析 总被引:9,自引:1,他引:9
分析了真空排污系统的污水流动主要形式及相关参数。采用两相流理论中的回流条件给出了不同管径下使污水提升的最小气流速度约为25~50m/s。采用均相流模型计算两相流中的沿程压力损失以预测真空排污系统的输送能力。分析表明,采用20cm的管网系统,其水平输送距离可达2~3km。 相似文献

Vacuum sewerage, as an alternative to conventional systems, is reasonably well known, and most civil engineers are aware that there can be significant capital savings on construction costs. These can be readily demonstrated on paper at the initial stages, but maintenance costs can only be determined from experience.
This investigation into the maintenance costs of the first two public vacuum sewerage schemes constructed in the UK compares the operational costs which were established and recorded in 1982-83 by South Holland District Council with those recorded in 1992-93 by Anglian Water Services Ltd.
The main body of evidence available is in the form of papers and reports prepared by Anglian Water's engineers who were taking a keen interest in this technology and monitoring its performance carefully. 相似文献
