The invention discloses an
aeration treatment device for high LAS
wastewater. The
aeration treatment device comprises a
sludge tank, an
aeration tank, a regulating tank, a water inlet and a
sewage inlet, wherein the
sludge tank, the aeration tank and the regulating tank are sequentially communicated; the water inlet is positioned on the upper side of the aeration tank; the
sewage inlet is positioned on the upper side of the
sludge tank; a sludge pump is arranged on the sludge tank; a lift pump is arranged on the regulating tank; and an aeration
pipe network is arranged at the bottom of the aeration tank. When
wastewater flows through the aeration tank, a large amount of foams are generated at the aeration tank, the foams are used as a carrier according to the surface adsorption principle of foams, solutes or particles in a
liquid phase can be separated, the concentration of pollutants such as LAS can be reduced, and then the foams are cleaned away; after the
wastewater is aerated, lower
clear liquid enters the regulating tank, and the pretreated wastewater is discharged to a subsequent
treatment unit by the lift pump, so that the LAS treatment pressure of a subsequent
system is practically and effectively reduced, and a large amount of foams are prevented from appearing on the liquid level of subsequent treatment equipment. The device is applied to the field of wastewater treatment.
