The specific working principle of the above embodiment is as follows:

during the drought period, municipal domestic sewage and industrial sewage all enter the diversion well 1 from the sewage pipe 2, the first water conservancy switch 17 is closed, the second water conservancy switch 18 is opened, the sewage directly enters the sewage treatment plant 15 through the sewage treatment pipe 12 for purification treatment, and the treated purified water is recycled through the discharge pipe 16 or is directly discharged into a natural water body.

In the early stage of rainfall, the initial rain flows into the sewage interception pipe 5, the sewage contained in the initial rain is intercepted on the left side of the rotary sewage interception plate 6 under the blockage of the rotary sewage interception plate 6, the intercepted rainwater is discharged into the diversion well 1 through the rainwater pipe 3, the first water conservancy switch 17 is switched on, and the intercepted rainwater is directly discharged into a natural water body through the first straight discharge pipe 4; along with continuous drainage of rainwater, dirt accumulates to block the rotary dirt intercepting plate 6, the pressure on the left side of the rotary dirt intercepting plate 6 is increased, the extrusion movable plate 702 moves downwards until the extrusion movable plate is contacted with the reverse rotation delay switch 704, the reverse rotation delay switch 704 triggers the control motor 29 to turn over by one hundred eighty degrees, meanwhile, the third water conservancy switch 19 is turned off, the fourth water conservancy switch 20 is turned on, the sewage pump 27 is started, meanwhile, the conductive permanent magnet 1103 is contacted with the first electric connection block 1104 under the influence of gravity, the first electromagnetic valve 21 is turned on, and the dirt in the dirt intercepting pipe 5 is conveyed to the sewage tank 25 through the shunt pipe 8 and the first pretreatment pipe 9 to be accumulated.

After the rotating sewage interception plate 6 is washed, the pressure in the sewage interception pipe 5 returns to normal, the movable plate 702 rises under the action of the return spring 708 to trigger the forward rotation delay switch 703, so as to drive the control motor 29 to turn over and be vertical to the axial direction of the sewage interception pipe 5 again, and rainwater is intercepted; along with the continuous emission of rainwater, the flow velocity of middle and later stage rainwater in intercepting dirty pipe 5 increases, and when comparing with the first rain, the filth volume of mixing in the rainwater reduces, rotates to intercept the accumulation rate of the filth on the left side of board 6 and does not change or reduce, and the rainwater after intercepting dirty directly discharges to the nature water through rainwater pipe 3 and first straight calandria 4.

When the amount of dirt mixed in rainwater is increased or unchanged, the accumulation speed of the dirt on the left side of the rotary dirt intercepting plate 6 is increased, the ascending and descending frequency of the movable plate 702 is increased, the magnetic rod 710 moves along with the movement of the movable plate 702 through the connecting rod 707, the induction coil 711 is matched with the magnetic rod 710 for use, induction current is generated in the induction coil 711 and is conducted to the fixed electromagnet 1102, the fixed electromagnet 1102 and the conductive permanent magnet 1103 repel each other, the conductive permanent magnet 1103 rises to be in contact with the second power connection block 1105, the first electromagnetic valve 21 is closed, and the second electromagnetic valve 22 is opened.

The rainwater mixed with dirt is conveyed to the position above the dirt intercepting net 24 in the pretreatment tank 23 through the flow dividing pipe 8, the sewage discharge pump 27 and the second pretreatment pipe 10, the filtered rainwater is discharged into a natural water body through the second straight-line net 14 through the filtration of the dirt intercepting net 24, and the dirt is collected above the dirt intercepting net 24; after the rainfall is finished, the fifth water switch 26 is turned on, the sewage accumulated in the sewage tank 25 is discharged to the sewage treatment plant 15, and the treated sewage is discharged through the discharge pipe 16.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
