Fire water source

In the practical sense of fire fighting, any water body that can be used for fire fighting can be used as fire fighting water source. The Code for Fire Protection Design of Buildings stipulates: "Fire water can be supplied by water supply network, natural water source or fire pool."

According to the Water Quality Standard for Urban Miscellaneous Water, the water quality meets the requirements of PH 6.0~9.0, chroma ≤30, no odor, turbidity ≤ 10, total dissolved solids ≤ 1 500, BOD5≤ 15, ammonia nitrogen ≤ 10, and anion surface.

1, reclaimed water

Reclaimed water is reclaimed water, which means that after proper treatment, sewage can reach a certain water quality index, meet certain use requirements and be used beneficially. Reclaimed water is mainly divided into urban reclaimed water reuse and community reclaimed water reuse. The current water treatment technology can treat sewage to meet the water quality standards required for fire fighting. In urban planning and community construction, reclaimed water can be used as fire water.

2. Circulating cooling water

Circulating cooling water refers to heat exchange through heat exchanger or direct contact heat exchange, which is recycled after being cooled by cooling tower to save water resources. The main difference between circulating cooling water and domestic water is that they contain different mineral ions and have different water temperatures, which can meet the water quality requirements of fire fighting water. Therefore, enterprises with circulating cooling devices can consider using circulating cooling water as fire water.

Step 3 rain

As a phased product of natural water cycle, rainwater has excellent water quality and is a very valuable water resource in the city. Through reasonable planning and design, and taking corresponding measures, urban rainwater can be used as fire water. This can not only alleviate the water supply contradiction of urban water resources to a certain extent, but also effectively reduce urban surface runoff and reduce flood control investment and disaster prevention losses.
