Embodiment 1

[0017] Such as Figure 1-2 As shown, the present invention includes a water tank 1, a baffle plate 2 and a drain pipe 3, the water tank 1 is welded by a bottom plate 4 and a side plate 5, the outside of the water tank 1 is connected with a baffle plate 2 through a cross brace 6, and the The water tank 1 is arranged inside the baffle plate 2, the upper edge of the side plate 5 is located between the upper edge and the lower edge of the baffle plate 2, and the water tank 1 and the drain pipe 3 are connected and welded together.

[0018] Working principle of the present invention: when the water level in the secondary settling tank 7 rises to the upper edge of the side plate 5 of the water tank 1, since the upper edge of the side plate 5 is located between the upper edge and the lower edge of the baffle plate 2, the upper edge of the water level The scum is blocked on the outside of the baffle plate 2, and the water level below the scum flows into the water tank 1 from the gap be...

Embodiment 2

[0020] Such as Figure 3-5 As shown, the present invention includes a water tank 1, a baffle plate 2 and a drain pipe 3, the water tank 1 is welded by a bottom plate 4 and a side plate 5, and the water tank 1 is welded to a pool wall 8 along the bottom plate 4 and the side plate 5, A baffle plate 2 is provided outside the water tank 1 . Both ends of the baffle plate 2 are disconnected and welded to the pool wall 8 . The drain pipe 3 is welded on the pool wall 8 and communicated with the water tank 1 .

[0021] Working principle is the same as embodiment 1.

Abstract

The invention discloses a secondary sedimentation tank dross filtration device. The secondary sedimentation tank dross filtration device comprises a water tank, a baffle and a drainage pipe and is characterized in that the water tank is formed by a bottom plate and side plates in a welded mode, the baffle is connected to the outer side of the water tank through cross braces, the water tank is arranged inside the baffle, the upper edges of the side plates are located between the upper edge and the lower edge of the baffle, and the water tank and the drainage pipe are connected and welded together. The secondary sedimentation tank dross filtration device has the advantages that dross is effectively prevented from entering the water tank, and thus the quality of drained water is improved.

Description

technical field [0001] The invention belongs to the field of sewage treatment equipment, in particular to a device for filtering scum in a secondary sedimentation tank. Background technique [0002] At present, buried integrated treatment equipment is mostly used in the field of domestic sewage treatment. It is a skid-mounted equipment that integrates hydrolysis and acidification tanks, contact oxidation tanks, secondary sedimentation tanks, disinfection tanks, and fan rooms. It is easy to install and operate. , Low cost and other characteristics. Among them, the secondary settling tank is a device for sedimentation and separation of the sewage treated by the hydrolysis acidification tank and the contact oxidation tank. The deposited sludge is discharged through the sludge discharge pump at the bottom of the secondary settling tank, and the upper part of the sedimentation is passed through the settling The drainage pipe in the secondary sedimentation tank is discharged, so ...
