Title:
ENERGY-SAVING SELF-OXYGENATION DISTRIBUTED BIOFILM SEWAGE TREATMENT APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/197640
Kind Code:
A1
Abstract:
Disclosed in the present invention is an energy-saving self-oxygenation distributed biofilm sewage treatment apparatus, relating to the field of sewage treatment devices. The present invention comprises an integrated treatment apparatus housing, a reaction tank body and a rotating biological cage structure, wherein the rotating biological cage structure comprises a mesh filler cage body, biofilm fillers, and porous partitions which carry the biofilm fillers to fall into water for self-oxygenation. During the slow rotation of the rotating biological cage, the porous partitions carry the fillers to fall into water to realize a self-oxygenation process, thus solving the problem of energy consumption caused by air blowing and aeration used for sewage treatment at the current stage. The device of the present invention is simple and easy to operate, involves a self-oxygenation process with low energy consumption, and has a large biomass, a high load impact resistance and generally low operation costs. Therefore, the present invention is expected to be widely used in economically underdeveloped rural areas where there are great fluctuations in water quality and water quantity, dispersed distribution, and a lack of professionals to perform maintenance.
