双向增压应急泵站在城市供水中的应用

Application of Bidirectional Pressure Booster Emergency Pump Station in Urban Water Supply

针对某市供水水源单一、地形狭长、供水不均衡、应急备用不足等特点,研发了双向增压应急技术,通过"近期管道增压,远期管道水库联合增压"的组合工艺模式,实现了单向水厂事故状态时全市范围的安全应急供水。工程调试结果表明,该技术设备简单、切换方便、管理简便,可有效解决多水厂联动困难、无法互为备用的问题,对提升当地供水安全等级具有重要意义。

In view of the characteristics of single urban water source, narrow terrain, unbalanced water supply, lack of emergency backup and etc., a bidirectional pressure booster technology was developed. Through the combination of recent pipeline pressurization and long-term pipeline reservoir pressurization, a city?wide emergency water supply in unidirectional water plant accident state was realized. Engineering commissioning results showed that the technical equipment was simple, easy to switch and manage. It could effectively solve the problems of multi-water plant linkage and mutually standby, and was of great significance for upgrading the local water supply safety level.
