According to the accompanying drawings 1-3, the storage tank device capable of shunting sewage comprises a storage tank 100, a water quality detection component (not shown in the figures), a water distribution component 200 and a water outlet component 300, wherein the water quality detection component is arranged in the storage tank 100, the water quality detection component is used for dividing rainwater in the storage tank 100 into a first grade and a second grade, the water distribution component 200 is used for conveying rainwater discharged through a rainwater drainage pipeline to the storage tank 100, the water outlet component 300 comprises a first water outlet pipeline 310 and a second water outlet pipeline 320, the first water outlet pipeline 310 is used for discharging rainwater of the first grade out of the storage tank, and the second water outlet pipeline 320 is used for discharging rainwater of the second grade out of the storage tank.
Specifically, the storage pond 100 is arranged at the end of a drainage basin, a rainwater drainage pipe is connected to the upstream of the storage pond 100, and rainwater in the rainwater drainage pipe enters the storage pond 100 through the water distribution assembly 200. The storage tank 100 is buried underground, and a water quality detection assembly (not shown in the figure) is arranged in the storage tank 100 and used for detecting the water quality in the storage tank 100. The water quality detecting assembly may be fixed to the bottom of the storage tank 100. It can be understood that the water quality detecting assembly can also be fixed at other positions of the storage tank 100 near the bottom, and even in the case of small rainfall, the water quality in the storage tank can be detected. The water quality detecting component may be a sensor for detecting the nitrogen-ammonia concentration of the rainwater in the storage tank 100, when the nitrogen-ammonia concentration of the rainwater in the storage tank 100 is greater than a first threshold, the grade of the rainwater in the storage tank 100 is a first grade, and the rainwater in the storage tank 100 may be discharged to a sewage plant or an external sewage treatment device through the first water outlet pipe 310. When the nitrogen-ammonia concentration of the rainwater in the regulation and storage tank 100 is less than or equal to the first threshold, the water quality in the regulation and storage tank 100 is of the second grade, and the rainwater in the regulation and storage tank 100 can be discharged into the river channel through the second water outlet pipeline 320. The first threshold may be determined according to emission standards of respective regions. The water quality detection assembly is arranged to determine the direction of rainwater diversion, so that rainwater discharged into the river channel can be ensured to meet the discharge standard, and the rainwater is prevented from polluting the water quality of the river channel. In addition, a part of rainwater which is not in accordance with the discharge standard can be sent to a sewage plant or a sewage treatment device for sewage treatment, the treated water can be used as industrial water or domestic miscellaneous water, the water pressure can be reduced, and the rainwater can be cleaned and shunted by the arrangement mode. It can be understood that the water quality detection assembly is not limited to only detecting the nitrogen ammonia concentration in the rainwater, and can select the water quality detection assembly which can be used for detecting other parameters of the water quality according to the actual conditions of rainwater pollutants in various places so as to achieve more precise management of the rainwater in the regulation and storage pool.
In some embodiments of the utility model, still include constructed wetland, constructed wetland sets up in the top of regulation pond 100, and the rainwater in the regulation pond still is divided into the third grade to the water quality testing subassembly, and play water assembly 300 still includes third outlet conduit 330, and third outlet conduit 330 is used for the rainwater of third grade to arrange to constructed wetland.
Specifically, if all the rainwater larger than the first threshold is sent to the sewage treatment plant for sewage treatment, the total amount is large, so that the workload of the sewage treatment plant is increased, the excessive sewage treatment cost is generated, and the water consumption cost is increased. In order to solve the above problem, the rainwater meeting the treatment standard of the sewage plant may be discharged to the sewage plant through the first outlet pipe 310 for treatment, and a second threshold value is set according to the treatment standard of the sewage plant, where the second threshold value is greater than the first threshold value, that is, the water greater than the second threshold value is the first grade water, the water less than the first threshold value is the second grade water, and the water greater than the first threshold value is the third grade water. When the water quality detection part detects that the concentration of the nitrogen and the ammonia in the regulation and storage tank 100 is greater than a second threshold value (first-grade rainwater), the rainwater in the regulation and storage tank 100 is discharged to a sewage plant or a sewage treatment device through a first water outlet pipeline 310 for treatment; for water with a concentration of nitrogen amine less than the first threshold (second grade water), it may be discharged directly to the river through the second outlet conduit 320; for rainwater (water of a third grade) with the nitrogen-ammonia concentration greater than the first threshold and less than the second threshold, the artificial wetland is arranged in the regulation and storage tank (as shown in fig. 2), and the rainwater is discharged to the artificial wetland through the third water outlet pipeline 330, so that nitrogen, phosphorus, suspended matters, heavy metals and the like in the rainwater can be effectively removed by the artificial wetland, and the rainwater treated by the artificial wetland can be recycled or directly discharged. Through carrying out classification treatment to the rainwater of different quality of water, can reduce the pollution, and can reduce the treatment cost, practice thrift the cost. Since the regulation and storage tank 100 is buried in the ground, and the artificial wetland is arranged above the regulation and storage tank 100 (as shown in fig. 2), the capacity of treating rainwater can be achieved, and the environment can be beautified.
