By the discharge delay cell system of collector pipe 41, when water level retracts H0 in water reserve 30, submersible sewage pump 36 is just stopped.
Water reserve 30 is stored after full water, in system in the cyclic process of rainwater, liquid level in water reserve 30 can under
Drop, but because the liquid level in regulatory region 25 is still highest flood level, therefore ball float 28 is because buoyancy is still in neck 27
Overhead height, so the second sealing plate 26 still can play sealing function to water inlet 34, will not intake again to retaining
Early-stage rainwater in area 30 is diluted.
In the present invention, after treating that rainfall stops, water inlet pipe 16 stops intaking to filter, and filter also stops to rainwater
Storage pond is intake, after biological delaying basin ceaselessly handles rainwater and discharges it system, though the water level in water reserve 30 is moved back
Return H0 and submersible sewage pump 36 is stopped, but be due to that the height of water level of regulatory region 25 remains at the tube top mark of the first overflow pipe 24
