- Abstract:
- Underground structural box (USB) is the main production area of an underground wastewater treatment plant (WWTP), and indoor fire hydrant is an important part of its fire protection design. However, the lack of specific guidance documents leads to a lot of inconvenience to the design work. In accordance with the requirements of current relevant regulations for indoor fire design of other underground spaces with the same size in China, the USB of an underground WWTP should be equipped with a fire hydrant extinguishing system, and the minimum and maximum design flow is 10 L/s and 40 L/s, respectively. The results of case study show that the engineering practice is consistent with the above laws: the design flow of fire hydrant in the USB of underground WWTP is generally not less than 10 L/s, and any fire point shall be guaranteed to be accessible by two solid streams from two fire guns; whether the automatic fire extinguishing system is installed or not has no influence on the design flow of fire hydrant in USB.
