High-efficiency integrated denitrification apparatus

Abstract

The invention relates to a high-efficiency integrated denitrification apparatus. The high-efficiency integrated denitrification apparatus comprises a membrane pool; an aeration-free MBR membrane vibrating device is arranged in the membrane pool; the membrane vibrating device comprises a support frame, a membrane host machine, up-and-down pulleys and a vibration traction mechanism; up-and-down supporting guide rails are arranged on the support frame; a plurality of MBR membrane modules are arranged in the membrane host machine; the membrane host machine is immersed in sewage in the membrane pool; the vibration traction mechanism is located out of the membrane pool; the membrane host machine is arranged on the up-and-down supporting guide rails via a plurality of the up-and-down pulleys and is in transmission connection with the vibration traction mechanism; and the vibration traction mechanism acts on the membrane host machine to drive the membrane host machine to carry out up-and-down vibration along the up-and-down supporting guide rails. The high-efficiency integrated denitrification apparatus provided by the invention has the advantages of reliability, stability, good decontamination effect, easiness in cleaning, thorough disinfection and excellent effluent quality; and when the membrane modules vibrates in the sewage, the accumulation of biochemical sludge on the surfaces of the membrane filaments is reduced and the contamination rate of the membrane filaments is slowed down.

Description

technical field [0001] The invention belongs to the field of sewage treatment, and in particular relates to an integrated high-efficiency denitrification device, in particular to a submerged MBR membrane non-aeration vibration device for low-concentration sewage treatment in municipal areas such as small towns and towns. Background technique [0002] Membrane bioreactor (Membrane Bioreactor, MBR) technology is a combination of biological reaction and membrane separation technology, using membrane as a separation medium to replace the secondary sedimentation tank for water discharge, the water quality of the produced water is stable, and it can change the reaction process and improve the reaction efficiency. sewage treatment methods. Membrane bioreactor is a basic water treatment unit assembled from membrane modules, gas distribution devices, water collection devices, membrane racks, etc., and placed in a biological reaction tank for solid-liquid separation. The current MBR ...
