Embodiment 1
[0030] Embodiment 1: Chemical workshop covers an area of S=1500m 2 , the daily transfer of chemicals in the workshop weighs about W=20 tons and is converted to N=20 m 3 , the volume of the storage tank is ≥20m 3 According to the GB50016-2006 standard, it is assumed that when a fire occurs, the total water output of the indoor fire nozzle and the outdoor fire nozzle within 3.0 hours of the fire accident fire fighting time is L=486m 3 , Xiamen local maximum rainfall within 3.0h is calculated as 40mm, then the estimated volume of rainwater E=S×T=60m 3 , the maximum estimated amount of fire accident wastewater=N+L+E= 566m 3 .
[0031] According to H=M / S= 37.8cm, the chemical workshop can form a 567m 3 Concentrated capacity pool, plus ≥2m 3 sump and 20m 3 The storage tank has a total capacity of 589m for collecting and storing fire accident wastewater 3 , enough to meet the collection and storage of the chemical workshop fire accident wastewater.
Embodiment 2
[0032] Embodiment 2: Chemical workshop covers an area of S=2000m 2 , the daily transfer of chemicals in the workshop weighs about W=30 tons and is converted to N=30 m 3 , the volume of the storage tank is ≥30m 3 According to the GB50016-2006 standard, it is assumed that when a fire occurs, the total water output of the indoor fire nozzle and the outdoor fire nozzle within 3.0 hours of fire fighting time is L=540m 3 , Xiamen local maximum rainfall within 3.0h is calculated as 40mm, then the estimated volume of rainwater E=S×T=80m 3 , the maximum estimated amount of fire accident wastewater=N+L+E=650m 3 .
[0033] According to H=M / S= 32.5cm, the chemical workshop can form a 650m 3 Concentrated capacity pool, plus ≥2m 3sump and 30m 3 The storage tanks have a total capacity of 682m for collecting and storing fire accident wastewater 3 , enough to meet the collection and storage of the chemical workshop fire accident wastewater.
Embodiment 3
[0034] Embodiment 3: chemical workshop floor area S=3500m 2 , the daily transfer of chemicals in the workshop weighs about W=40 tons and is converted to N=40 m 3 , the volume of the storage tank is ≥40m 3 According to the GB50016-2006 standard, it is assumed that when a fire occurs, the total water output of the indoor fire nozzle and the outdoor fire nozzle within 3.0 hours of fire fighting time is L=540m 3 , Xiamen local maximum rainfall within 3.0h is calculated as 40mm, then the estimated volume of rainwater E=S×T=140m 3 , the maximum estimated amount of fire accident wastewater=N+L+E=720m 3 .
[0035] According to H=M / S= 20.6cm, the chemical workshop can form a 721m 3 Concentrated capacity pool, plus ≥2m 3 sump and 40m 3 The storage tanks have a total capacity of 763m for collecting and storing fire accident wastewater 3 , enough to meet the collection and storage of the chemical workshop fire accident wastewater.
