The utility model discloses in, vatch basin 1 sets up in confluence drainage system end with relevant business turn over water pipe.
In sunny days, as the water level of the drought flow sewage in the intercepting well is positioned below the top of the overflow weir, the drought flow sewage directly enters a downstream intercepting pipe and is finally conveyed to a sewage treatment plant for treatment; in rainy days, when the water level of the mixed sewage in the intercepting well is still below the top of the overflow weir, the mixed sewage can still directly enter a downstream intercepting pipe and is finally conveyed to a sewage treatment plant for treatment; when the water level of the mixed sewage in the intercepting well rises along with the increase of rainfall, when the water level overflows the overflow weir, part of the mixed sewage turns over the overflow weir to enter a water outlet pipe or a rainwater storage tank, and at the moment, the intercepting pipe reaches the designed maximum flow.
The utility model discloses in, the vatch basin, the inlet tube, the outlet pipe, the big or small size of damming pipe and overflow weir can design according to actual engineering needs and confirm.
The utility model designs an intercepting system, which intercepts sewage in the confluence pipe in sunny days or early rainy days and connects the sewage into a sewage pipe network of a municipal road so as to prevent the urban water body from being polluted more seriously; the overloaded mixed sewage enters a municipal rainwater pipe network or a rainwater storage tank in heavy rainy days.
