<p>The method of wastewater treatment and the method-applying apparatus in the sequencing batch reactors, where after separating the activated sludge from the treated water the treated water is drawn off via a decanting apparatus from the sub-surface layer of water in the reactor. The decanted water is conveyed by the decanting apparatus to a separate tank of the air-lift pump, which is separated in a watertight way from the inside of the reactor. The treated water is pumped off from the separate tank of the air-lift pump to the outlet by the air-lift pump, the inlet of which is located at the level corresponding to the delivery yield of the air-lift pump. The submerged inlet part of the decanting apparatus moves vertically alongside with the fluctuating water level in the reactor.</p> |
