Wastewater processing tank

The invention discloses a wastewater processing tank, which comprises a tank body, a stirring cavity, a rotation shaft, and a driving motor. A stirring and vibrating device comprises a stirring shaft,which cooperates with the rotation shaft; an elastic stirring assembly, which is arranged on the stirring shaft; and a driving assembly, which cooperates with the stirring shaft and is used to drivethe stirring shaft to move up and down. A feed bin is arranged above the tank body. A spraying device, which cooperates with the feed bin, is arranged in the tank body. The spraying device comprises ashunting chamber, a dropping channel for communicating the shunting chamber and the feed bin, and nozzles, which are separately arranged in the lower part of the shunting chamber. By setting the shunting chamber and arranging nozzles in the shunting chamber, medicament is evenly distributed in wastewater, thus the medicament can be rapidly and uniformly distributed in wastewater, wastewater is well disinfected, moreover, t
