Ceramic film oxygen-transfer biofilm reactor

Abstract

The invention belongs to the field of water treatment devices. The invention in particular relates to a ceramic film oxygen-transfer biofilm reactor. The biofilm reactor is characterized by comprisinga shell, a ceramic film module, a water distribution pipe and an aeration pipe are sequentially arranged in the shell from top to bottom; a plurality of water production holes are distributed in thewater distribution pipe; a plurality of aeration holes are distributed on the aeration pipe, a water production tank is arranged at the upper part of the side surface of the shell, a water outlet is arranged at the bottom of the water production tank, the side surface of the shell is also provided with a film module air inlet communicated with the ceramic film module, a film module air outlet, a raw water inlet communicated with the water distribution pipe, and an aeration port communicated with the aeration pipe, and the bottom of the shell is provided with a sludge discharge and a vent nozzle. The ceramic film oxygen-transfer biofilm reactor has the advantages that: 1, the installation is easy; 2, the sludge amount is small; 3, modular design is adopted, and the occupied area is small; 4, high efficiency and energy saving.

Description

technical field [0001] The invention belongs to the field of water treatment devices, and in particular relates to a ceramic membrane oxygen transfer biofilm reactor. Background technique [0002] The full name of MABR is Membrane Aerated Biofilm Reactor (Membrane Aerated Biofilm Reactor), which combines the characteristics of COD / BOD removal, nitrification / denitrification, etc., but it still belongs to the traditional process technology, and there are some disadvantages, such as: [0003] 1) In engineering applications, the MABR technology of the traditional process still needs to be combined with the traditional activated sludge process, or combined with the traditional biofilm process, which is mainly reflected in the process: MABR membrane process + activated sludge process (biofilm process) combination, the process flow is lengthy, and the capital construction cost is high. [0004] 2) The chemical stability of the membrane is poor, the corrosion resistance is poor, t...
