Step c, a fire-fighting pool 5 water quality purifying step: when the water quality monitor detects that the water quality in the fire-fighting water tank 5 is lower than the threshold value, an instruction is sent to the control system, the control system controls to close the second control valve 62 and the third control valve 63, the fourth control valve 64 and the sixth control valve 66 are opened, the water return pump 35 and the clean water pump 34 are opened, the water return pump 35 pumps the water in the fire-fighting water tank 5 into the water quality purifier 3 for purification, the purified water flows back into the fire-fighting water tank 5 through the fire-fighting water supplementing pipe 32, after the water quality in the fire-fighting water tank 5 meets the requirement, the water quality monitor sends the instruction to the control system, the sixth control valve 66 and the water return pump 35 are closed, and the second control valve 62 and the third control valve 63 are opened.
Taking Nanjing Nanju Kong scientific city guarantee house project as an example, the project planning land is 2.63 ten thousand square meters, a rainwater collecting tank 300m 3 is arranged, the rainwater collecting tank is processed by a water purifier 3 (20 m/h) arranged in a rainwater machine room and then is sent to a clean water tank with the volume of 30m 3, and a clean water lifting pump is used for supplying the greening irrigation and the road flushing for the community. The rainwater after primary rainwater is discarded is stored in a rainwater reservoir, and flows into a clean water tank for greening and irrigation after being treated by a rainwater module.
In order to improve the water quality after the water which is immobilized with the fire-fighting pool for a long time is treated by the rainwater module, a recycling pump and an electromagnetic valve for absorbing water from the fire-fighting pool are added.
At ordinary times, the fire-fighting water tank and the rainwater utilization clean water tank are communicated by a communicating pipe, the elevation of the water surface is consistent, the pipe top of the communicating pipe is erected at the lowest alarm water level of the fire-fighting water tank, a siphon damage hole is formed in the pipe top, when the clean water tank booster pump supplies greening and irrigation, the water surface of the clean water tank is lowered, the water surface of the fire-fighting water tank is lowered due to the communication of the two water tanks, the water inlet pipe of the fire-fighting water tank starts to enter water at the moment, when the fire-fighting water tank enters water, a signal is sent to close the fifth control valve, the water of the fire-fighting water tank is prevented from being used at will, and the siphon damage hole ensures that the water level of the fire-fighting water tank is prevented from flowing into the rainwater utilization clean water tank when the water tank is lowered to the lowest alarm water level.
When the water quality monitor of the fire water tank monitors that the water quality is deteriorated and needs to be circularly treated, the fourth control valve and the sixth control valve are opened, the second control valve and the third control valve are closed, the water return pump is started to treat the fire water tank, and the effective volume 692 m 3 of the fire water tank in the project and the total volume 941m are provided. According to the treatment capacity of the rainwater treatment module of 20T/h, the water treatment of the fire-fighting pool is carried out once for 47.05 hours, the water of the fire-fighting pool can be treated at one time, the water of the fire-fighting pool can also be circularly treated intermittently according to the irrigation condition, when the water quality of the fire-fighting pool reaches the standard after monitoring, the operation of the water return pump is stopped at any time, the sixth control valve is closed, and meanwhile, the second control valve is opened to continue the rainwater recycling treatment and also serve as the water replenishing of the fire-fighting pool. When the water level of the fire water tank reaches the fire water level Z+2.65m, the fourth control valve is closed, and the water supplementing of the fire water tank is stopped.
When the fire-fighting water tank is started for the first time, the municipal tap water pipe supplies water, the automatic water level control valve stops water inflow when reaching the lowest alarm water level, the water inlet pipe of the rainwater utilization device supplements water to the fire-fighting water level, and the water supply pipe controlled by the fourth control valve supplements water for the fire-fighting water tank at ordinary times, so that the water quantity lost by evaporation and leakage of the water tank at ordinary times is saved.
The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above examples, and all technical solutions belonging to the concept of the present invention belong to the protection scope of the present invention. It should be noted that modifications and adaptations to the invention without departing from the principles thereof are intended to be within the scope of the invention as set forth in the following claims.
