[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] like Figure 1-4 As shown, a rainwater and sewage separation treatment structure that is convenient for adjusting flow rate includes a pool 1 provided with a cover 11. The pool 1 is divided into a rainwater pool 12, a regulating pool 13 and a sedimentation pool 14 according to function. The rainwater pool 12 is connected to a drain valve 121, and further includes:

[0026] A side frame 21 that moves between the rainwater tank 12 and the regulating tank 13 and has a plurality of notches;

[0027] The float 22 is fixedly mounted on the end of the side frame 21 , and the float 22 cooperates with the rainwater pool 12 to drive the side frame 21 to move.

[0028] Specifically, the cover body 11 is connected with a rainwater inlet pipe and a sewage inlet pipe, and both the rainwater inlet pipe and the sewage inlet pipe are provided with electronic regulating valves to control the amount of water entering the rainwater pool 12 and the regulating pool 13, which is a prior art and will not be described in detail here; and the rainwater inlet pipe replenishes rainwater into the rainwater pool 12, and the sewage inlet pipe replenishes sewage into the regulating pool 13 (such as Figure 1 and Figure 2 as shown).

[0029] Furthermore, the float 22 is movable in the rainwater pool 12, and the drain valve 121 is fixedly installed on the side wall of the rainwater pool 12, and is used to cope with extreme rainfall and has flood discharge capability. This is existing technology and will not be described in detail here.

[0030] Sewage is added to the regulating tank 13 through the sewage inlet pipe, and the sewage enters the sedimentation tank 14 for treatment and then discharged. In rainy days, rainwater enters the rainwater tank 12, and the float 22 is driven upward by the rising water surface, so that rainwater is added to the regulating tank 13 from the rainwater tank 12 through the side frame 21, so as to neutralize the carbon source content of the sewage in the regulating tank 13. At the same time, with the multiple notches on the side frame 21, the dirt in the rainwater tank 12 can be intercepted, reducing the dirt entering the regulating tank 13 and Interference with the neutralization of the carbon source content; after the neutralization is completed, the electronic regulating valve on the rainwater inlet pipe is closed to stop the rainwater from being injected into the rainwater pool 12, so that the drain valve 121 on the side wall of the rainwater pool 12 is opened to drain water, so that the water level in the rainwater pool 12 drops and drives the float 22 to move downward, so that the rainwater pool 12 stops injecting rainwater into the regulating pool 13, and when sewage is added to the regulating pool 13 again, the operation is repeated to ensure that the carbon source content in the regulating pool 13 remains stable, reduce the incompleteness of sewage treatment, and reduce the problem of difficult sewage treatment.

[0031] As an embodiment further provided by the present invention, a partition is provided between the rainwater tank 12 and the regulating tank 13 , and a guide hole 15 matching with the side frame 21 is opened on the partition.

[0032] Specifically, the partition is fixedly installed in the pool 1, which is a prior art and will not be described in detail here. The side frame 21 is movable at the end of the diversion hole 15, and a sealing plate 151 with a torsion spring is hingedly provided at the end of the diversion hole 15 (such as Figure 3 As shown), the cross section of the end of the sealing plate 151 is arc-shaped, and a sealing rubber ring is fixedly sleeved on the sealing plate 151.

[0033] The sealing plate 151 is pushed and deflected during the upward movement of the side frame 21, accompanied by the deformation of the torsion spring, so that the side frame 21 opens the guide hole 15 to allow rainwater to flow in. At the same time, the side frame 21 is outside the guide hole 15 to intercept and process the dirt in the rainwater.

[0034] As another embodiment further provided by the present invention, a partition is provided between the regulating tank 13 and the sedimentation tank 14, and a filter frame 23 is hingedly provided on the partition.

[0035] Specifically, the partition is fixedly installed in the pool 1, which is a prior art and will not be described in detail here. The filter frame 23 has a multi-layer sheet cross section, and the multi-layer filter sheets are gradually narrowed along the water flow direction, so as to achieve the purpose of layer-by-layer filtration. This is a prior art and will not be described in detail here (such as Figure 2 as shown).

[0036] The mixed water in the regulating tank 13 can filter suspended particles and pollutants through the filter frame 23 and then flow to the sedimentation tank 14 , thereby reducing the load of the sedimentation tank 14 .

[0037] As another embodiment further provided by the present invention, a driving frame 2 movable in the regulating tank 13 is fixedly mounted on the filter frame 23 , and the side frame 21 is fixedly mounted on the driving frame 2 .

[0038] Specifically, the driving frame 2 is also provided with a notch which is the same as that of the side frame 21 .

[0039] By moving the side frame 21 upward, the driving frame 2 is driven to deflect and tilt, so as to provide support force for the float 22 to move upward. In the process of replenishing sewage into the regulating tank 13 through the sewage inlet pipe, the sewage first flows into the notch on the driving frame 2, so that the inclined driving frame 2 can additionally intercept the dirt in the sewage and reduce the processing burden of the regulating tank 13.

[0040] As another embodiment further provided by the present invention, the filter frame 23 is divided into a main filter plate 231 and an auxiliary filter plate 232 according to the shape, and the driving frame 2 is deflected at a predetermined angle to enable the main filter plate 231 to move on the port of the sedimentation tank 14.

[0041] By deflecting and tilting the driving frame 2, the originally vertical main filter plate 231 is tilted, and the port of the sedimentation tank 14 is covered, so that the main filter plate 231 composed of multiple layers of filter plates provides a shield for the top of the sedimentation tank 14, preventing the water flow from disrupting and re-suspending the dirt that has sunk in the sedimentation tank 14, thereby reducing the burden of sewage treatment.

[0042] As another embodiment further provided by the present invention, the driving frame 2 deflected at a predetermined angle enables the auxiliary filter plate 232 to replace the main filter plate 231 .

[0043] Specifically, by deflecting and tilting the driving frame 2, the auxiliary filter plate 232 originally located above the water surface of the regulating tank 13 is lifted up and obliquely placed between the regulating tank 13 and the sedimentation tank 14, so that the auxiliary filter plate 232 can play a filtering role and maintain the filtering effect when the mixed water in the regulating tank 13 enters the sedimentation tank 14, which is not easy to interfere with the sewage treatment, making the sewage treatment more efficient, and having the effects of energy saving, reducing operation and maintenance time and facilitating operation.

[0044] Working principle: On rainy days, rainwater enters the rainwater pool 12, and the float 22 is driven upward by the rising water level, so that the rainwater is added from the rainwater pool 12 to the regulating pool 13 through the side frame 21, so as to neutralize the carbon source content of the sewage in the regulating pool 13. At the same time, with the multiple notches on the side frame 21, the dirt in the rainwater pool 12 can be intercepted to reduce the interference of the dirt entering the regulating pool 13 with the neutralization of the carbon source content; after the neutralization is completed, the electronic regulating valve on the rainwater inlet pipe is closed to stop the rainwater from being injected into the rainwater pool 12, so that the drain valve 121 on the side wall of the rainwater pool 12 is opened to drain water, so that the water level in the rainwater pool 12 drops and drives the float 22 to move downward, so that the rainwater pool 12 stops injecting rainwater into the regulating pool 13.

[0045] Secondly, the filter frame 23 enables the mixed water in the regulating tank 13 to filter suspended particles and pollutants and then flow to the sedimentation tank 14, thereby reducing the load of the sedimentation tank 14. The driving frame 2 deflects and tilts to tilt the originally vertical main filter plate 231 and cover the port of the sedimentation tank 14, so that the main filter plate 231 composed of multiple layers of filter discs provides a shield for the top of the sedimentation tank 14, thereby preventing the water flow from disrupting and re-suspending the dirt that has sunk in the sedimentation tank 14.

[0046] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
