Meanwhile, the flow abandoning controller is closed when the high liquid level of the reservoir is alarmed, so that excessive rainwater overflows to a municipal rainwater pipe network in a safe diversion well under the condition of overlarge rainfall during rainstorm. The multipoint signal series connection monitoring control point positions comprise:
(1) determining the time (conventional value) of rainfall runoff of 2-3mm at the initial stage of flow abandoning according to the confluence area and the confluence time;
(2) determining the collection time according to the rain frequency, and if the time interval between two rains in Nanjing is within 12h, not discarding the flow (dynamic value);
(3) depending on the reservoir level, it is determined whether to collect (alarm value).
The underground purification all-in-one machine 330: the rainwater after the abandoning and the primary filtration is subjected to advanced treatment and multi-stage filtration, and the filtration precision reaches the micron level. The filtering area of a single device reaches 3 square meters, the sewage accommodating space is large, and the treated rainwater directly enters the rainwater storage tank 440 to be stored for later use.
Rainwater reservoir 440: storing the rainwater after the flow abandoning, adopting a reinforced concrete structure and internally arranging a water quality maintaining system to prevent the water quality from deteriorating and changing into odor.
Rainwater on roof and ground is collected, enters the underground purification all-in-one machine 330 after primary rainwater discarding and filtering, enters the rainwater reservoir 440 after being processed by the underground purification all-in-one machine 330, and the processed rainwater is reused for greening and road watering.
The rainwater reservoir water replenishing adopts tap water to set a backflow preventer for water replenishing, adopts an electromagnetic valve and liquid level control automatic water replenishing, and ensures that the water quantity requirement of greening and road sprinkling reuse water can be met.
The treated rainwater is conveyed to each water using point by a constant pressure water supply pump set.
Description of operation control:
the rain gauge is arranged on the outdoor ground and used for monitoring parameters such as rainfall and the like in real time and controlling the starting and stopping of the rainwater flow abandoning device.
Description of liquid level control of the rainwater reservoir:
when the liquid level in the rainwater reservoir is low, the reservoir sludge pump and the recycling pump cannot be started;
when the liquid level in the rainwater reservoir is high, the rainwater discarding control valve is closed, and rainwater cannot enter the rainwater reservoir.
When the liquid level in the rainwater storage tank is a medium-low liquid level, the water replenishing electromagnetic valve is opened;
when the liquid level in the rainwater storage tank is high, the tap water replenishing electromagnetic valve is closed.
As shown in fig. 2, the purified water collection process flow is as follows: the safe diversion well, the rainwater flow abandoning device, the buried purification integrated machine, the rainwater reservoir and the like are recycled.
Rainwater flows through a rainwater flow abandoning device, the rainwater flow abandoning device abandons early rainwater, performs rough filtration pretreatment, and then directly flows into the underground purification all-in-one machine by gravity for deep purification treatment, and the treated water quality reaches the reuse standard; gravity flows into a rainwater reservoir. Only the electric valve of the flow discarding filter needs to be automatically opened and closed by a power supply according to rainfall in the whole process, and other parts have no energy consumption; no personnel management is required.
The utility model has the advantages that:
1. clean water is collected, no dirt enters the water storage tank, and the water storage tank is kept clean all the time.
2. No need of power to lift and pressurize, and zero energy consumption. (electric valve switch energy consumption can be ignored basically)
