Problems solved by technology
[0002] The main technological process of the existing domestic sewage buried equipment is: hydrolytic acidification - contact oxidation tank - secondary sedimentation tank - clear water tank - effluent - discharge, the effluent is difficult to meet the first-level standard of comprehensive sewage discharge standards; due to the secondary sedimentation in the original equipment The pool is an ordinary sedimentation tank, and the sedimentation effect is not ideal, which affects the water quality of the clear water pool; at the same time, the direct water out of the equipment cannot meet the higher discharge standards without filtering.

Embodiment Construction
[0015] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0016] Such as figure 1 Shown: a new type of buried sewage treatment device, including hydrolytic acidification tank 2 and contact oxidation reaction tank 3 buried underground, domestic sewage is sent to hydrolysis acidification tank 2 and contact oxidation reaction tank through the water inlet pipe 1 by the lift pump 3 for treatment, a sloping plate sedimentation tank 4 is provided on the back side of the contact oxidation reaction tank 3, and a BAF aerated biological filter 5 is provided on the back side of the sloping plate sedimentation tank 4, and the sloping plate sedimentation tank 4 and the BAF aerated biological filter The connecting pipe between the tanks 5 is L-shaped, and the water level of the water inlet of the connecting pipe in the inclined plate sedimentation tank 4 is higher than the water level of the water outlet of the connecting pi...

The invention discloses a novel underground sewage treatment device. The novel underground sewage treatment device comprises a hydrolytic acidification tank (2) and a contact oxidation reaction tank (3), wherein a plated sedimentation tank (4) is arranged on the rear side of the contact oxidation reaction tank (3); a BAF (biological aerated filter) (5) is arranged on the rear side of the plated sedimentation tank (4); a clean water tank (6) is arranged on the rear side of the BAF (5); wastewater treated through the contact oxidation reaction tank (3) enters the plated sedimentation tank (4) through a weir flow chamber on one side of the contact oxidation reaction tank (3), so as to be subjected to sedimentation treatment; discharged water from the plated sedimentation tank (4) enters the BAF (5) through a communicating tube at the bottom of the BAF (5); wastewater treated through the BAF (5) enters the clean water tank (6) through a water outlet weir plate arranged above the BAF (5). The sewage treatment device can enhance the water quality of discharged water and reduce the operation energy consumption, and has durable stability and effectiveness.
Description
technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a novel underground sewage treatment device capable of improving effluent water quality, reducing operating energy consumption, and having lasting stability and effectiveness.
