The working principle of the invention is as follows:
sewage produced in production and life of a whole plant enters the sewage station 1 through the sewage discharge system, the sewage is treated by the sewage station 1 to become reclaimed water with standard water quality, the reclaimed water flows into the reclaimed water tank 7 through the reclaimed water tank water inlet pipeline 6, the reclaimed water can be stored in the reclaimed water tank 7, even if the liquid level of the reclaimed water tank 7 rises to an extra-high water level and reaches an overflow water level, the reclaimed water in the reclaimed water tank 7 is discharged into the drainage system 38 (the drainage system 38 is a drainage ditch connected with a municipal drainage system) through the water seal 43 and the first overflow pipe 44, and the water seal 43 can prevent peculiar smell in the drainage ditch 38 from entering the reclaimed water tank 7 through the first overflow pipe 44.
The reclaimed water in the reclaimed water tank 7 flows into the reclaimed water tank 7 after being circulated through the circulating conveying pipeline 23. When the recycled water is supplied circularly, the recycled water in the circulating conveying pipeline 23 can be supplied to green land for watering flowers and plants through the green land water supply pipeline and the green land water using equipment 19, the recycled water in the pipeline 16 can be supplied to toilets for flushing toilets through the toilet water supply pipeline and the toilet water using equipment 18, the toilet water using equipment 18 and the green land water using equipment 19 can respectively represent or connect a plurality of toilets and a plurality of green lands, and the thirteenth water pump 3 and the fifth water pump 41 can be a plurality of water pumps according to actual conditions. The fifth water pump 41 supplies water at a constant pressure to ensure that the subsequent pipes always have a certain pressure, so that water is always in the pipes when the toilet is flushed.
The middle water tank 7 is provided with a first liquid level sensor 15, when the water level of the middle water tank 7 is lower and reaches a certain set low water level, the water amount in the middle water tank is insufficient, particularly, the water amount for watering flowers and plants in summer is large, in order to avoid that the water amount for flushing a toilet is insufficient due to too much water consumption for watering flowers and plants in a green land, the first liquid level sensor 15 gives a signal to control the third electric valve 20 to be automatically closed when the water level is low, and the watering of flowers and plants in the green land 1 is stopped. The electric valve can be set to water flowers only during weekends or off duty, so that the toilet flushing water is not influenced by the flower watering. If the amount of reclaimed water is particularly large, the third electric valve 20 can be manually opened to water flowers and plants on the green land in order to reduce the amount of reclaimed water discharged.
The reclaimed water in the reclaimed water tank 7 can also enter the water storage tank 30 through the water storage tank inlet pipeline 24 to be used as landscape water, so that the landscape water can be used without tap water, and the tap water is saved. When the water level of the middle water pool 7 reaches a certain set low water level, in order to prevent the shortage of the middle water, the first liquid level sensor 15 of the middle water pool 7 gives a signal, the tenth water pump 34 is started, at this time, the middle water in the water pool 30 can enter the circulating conveying pipeline 23 through the water pool drainage pipeline 37, the water can be directly supplied to the toilet 1 and the green land, meanwhile, the middle water can enter the middle water pool 7 through the eighth stop valve 13 and the eighth check valve 14 to supplement the water to the middle water pool, and when the water level of the middle water pool 7 reaches a certain set high water level, the tenth water pump 34 stops running, namely, the middle water in the water pool 30 is stopped.
If the amount of reclaimed water produced by the sewage station 1 increases and the reclaimed water reservoir 7 returns to a certain high level, the ninth electrically operated valve 26 is opened to replenish the reservoir 30 with reclaimed water, when the water level of the water reservoir 30 reaches a certain set high level, the float valve 28 is automatically closed, and the second liquid level sensor 29 arranged on the water storage tank 30 gives a signal, the ninth electric valve 26 also automatically closes to stop supplying water to the water storage tank 30, the ninth electric valve 26 and the float valve 28 can prevent the water storage tank 30 from overflowing, thereby having double protection effect on preventing the landscape water tank from overflowing, even if the ninth electrically operated valve 26 and the float valve 28 simultaneously fail to raise the water level of the reservoir 30 to an extra high level, to prevent the landscape pool 29 from flooding to the ground, the reclaimed water can be drained into the drainage system 38 through the water seal 31 and the second overflow pipe 32, and the water seal 31 can prevent odor in the drainage ditch 38 from being transmitted into the water reservoir 30 through the second overflow pipe 32 to affect the surrounding environment.
If the amount of reclaimed water generated by the sewage station 1 is reduced, the water level of the water storage tank 30 is lower, and the reclaimed water cannot be supplied to the reclaimed water tank 7, the water level of the reclaimed water tank 7 reaches a certain specific low water level, and the reclaimed water cannot meet the requirement of flushing the toilet, at the moment, the first liquid level sensor 15 gives a signal, the second electric valve 9 is opened, the tap water enters the reclaimed water tank 7 through the pipeline 10, the second electric valve 9 and the second check valve 8, the tap water is supplied to the reclaimed water tank 7, when the reclaimed water tank 7 reaches a certain set normal water level, the first liquid level sensor 15 gives a signal, the second electric valve 9 is automatically closed, and the supply of the tap water to the reclaimed water tank 7 is stopped, so that the influence on the water for the toilet or the influence on. Even if the sewage station is in failure or the middle water pool needs to clean bottom sludge, the eighth stop valve 13 can be closed, and the first stop valve 11 is opened, so that tap water can directly enter the circulating conveying pipeline 23 through the first stop valve 11 and the first check valve 12 to supply water to the toilet, the green land and the water storage pool 30, and normal water use is prevented from being influenced by no water in the middle water system.
The invention divides qualified reclaimed water into different purposes by a plurality of reclaimed water utilization systems for utilization, wherein the reclaimed water utilization systems comprise a recycling system and a storage water utilization system, the recycling system can be used for watering flowers and plants (green land water utilization equipment) and flushing toilets (toilet water utilization equipment), and the storage water utilization system is used as landscape water (water storage tank). The water storage tank has the functions of landscape water and water storage, when the amount of reclaimed water is insufficient, the water in the water storage tank can be supplemented into the reclaimed recycling system to flush toilets and water flowers and plants, and when the amount of reclaimed water is more, the reclaimed water is used for supplementing the water in the water storage tank, so that the water storage tank plays the roles of buffering and adjusting the recycling system, and the landscape water tank beautifies the environment of a plant area.
