PURPOSE: A rainwater treatment apparatus is provided to effectively discharge solid materials accumulated deposited on settling and separating manholes to the outside without a sludge discharge pipe and a discharge pump. CONSTITUTION: A rainwater treatment apparatus comprises a settling manhole(202), a separating manhole(204), an inlet pipe(206), a water sloping device(300), and a sludge outlet pipe(220). The separating manhole is connected to the settling manhole. Rainwater flows into the settling manhole through the inlet pipe. The water sloping device is connected to the inlet pipe. The sludge outlet pipe connects the bottom of the settling manhole to the bottom of the separating manhole. |
