Detailed Description
As shown in fig. 1, this embodiment is a rainwater treatment system suitable for sponge city construction, including rainwater collecting pipe, initial rainwater storage pond, cistern and transition pond etc. wherein rainwater collecting pipe one end intercommunication venue roofing rainwater collection mechanism, the other end extends to municipal drainage pipe network, is equipped with initial rainwater storage pond and transition pond on this rainwater collecting pipe in proper order along rainwater flow direction.
The water storage capacity of the initial rainwater storage tank in this example is determined based on the area of the venue roof so as to ensure that the initial rainwater on the venue roof can be completely collected. The initial rainwater storage pool is communicated with a rainwater collecting pipe above the first inspection well, wherein the rainwater collecting pipe is connected to the top end of the initial rainwater storage pool, the bottom of the initial rainwater storage pool is connected with a first drain pipe, and an electromagnetic valve is arranged on the first drain pipe. The bottom surface of initial stage rainwater storage pond is to the domatic of first drain pipe slope to collect the impurity in rainwater and the rainwater, be convenient for discharge.
In the embodiment, the transition pool is connected to the rainwater collecting pipe, the bottom plate in the transition pool is provided with an overflow partition wall, an overflow groove is formed on the overflow partition wall near the water inlet side, a small-sized drain pipe and a sensor (such as a water level sensor) capable of generating a signal when water in the overflow groove is emptied are arranged in the overflow groove, and the sensor is in circuit connection with the electromagnetic valve on the first drain pipe; the bottom plate at the other side of the overflow partition wall is provided with a communication hole.
In this embodiment, the reservoir is located below the transition pool and is connected with the transition pool into a whole, and the top of the reservoir is provided with a second inspection well. The top plate of the reservoir is provided with a communication channel which can be communicated with the communication hole on the bottom plate of the transition reservoir, and the bottom of the reservoir is connected with a second drain pipe.
The working principle of the implementation is as follows:
in the early stage of rainfall, rainwater collected by a roof rainwater collecting mechanism of a venue enters a rainwater collecting pipe, the rainwater flows in the rainwater collecting pipe to the municipal drainage pipe network, and the rainwater falls into an initial rainwater storage pool below through a first inspection well when passing through the first inspection well;
after a period of rainfall, the initial rainwater storage pool is filled with rainwater, and the rainwater which subsequently enters the first inspection well flows to the transition pool through the rainwater collecting pipe;
rainwater entering the transition pool is firstly collected in an overflow groove in the transition pool, and enters the reservoir through the overflow partition wall after the overflow groove is fully filled;
after the reservoir is filled, the rainwater which subsequently enters the transition pool flows to the municipal drainage pipe network through the rainwater collecting pipe, and the rainwater in the reservoir can be used for greening irrigation, toilet water, car washing and the like after simple answering treatment.
In this embodiment, the initial rainwater storage tank is provided with the water level sensor, and when the water level in the initial rainwater storage tank stops rising before the initial rainwater storage tank is filled with the initial rainwater (the rainfall in the field is small and the initial rainwater storage tank cannot be filled with the initial rainwater storage tank), the electromagnetic valve is controlled to drain after a certain time so as to cope with the next rainfall. The electromagnetic valve automatically stops after working for a certain time, and the working time can ensure that the initial rainwater storage pool is emptied.
When the rainfall stops, the rainwater collecting pipe stops delivering water to the overflow tank, the water level of the rainwater accumulated in the overflow tank gradually drops under the action of the small drain pipe until the rainwater is emptied, and after the rainwater is emptied, the sensor in the overflow tank generates a signal, and the electromagnetic valve is controlled to drain water so as to cope with the next rainfall.
The above embodiments are only for illustrating the inventive concept of the present utility model and not for limiting the protection of the claims of the present utility model, and all the insubstantial modifications of the present utility model using the concept shall fall within the protection scope of the present utility model.
