Abstract

The invention discloses an MBR and MMBR composite sewage treatment system based on panel ceramic membranes. The composite sewage treatment system comprises a raw water facility, a raw water pump, bioreactors, a suction pump and a clean water pond, wherein each bioreactor comprises a reactor body, an aerating device and a sludge discharging system, and panel ceramic membranes and MBBR suspended fillers are organically combined in the same bioreactor and share the aerating device and the sludge discharging system; and an input end of the raw water pump is communicated with the raw water facility, an output end of the raw water pump is communicated with the internal space of the reactor body, an input end of the suction pump is communicated with outlets of the panel ceramic membranes, and an output end of the suction pump is communicated with the clean water pond. By combining the advantages of an MBR and an MBBR, a relatively good sewage treatment effect, particularly to high-COD and unmanageable industrial wastewater can achieved, and furthermore, the occupied area of a sewage plant can be reduced.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to a composite sewage treatment system organically combining MBR and MBBR processes based on flat ceramic membranes. Background technique [0002] Membrane bioreactor (MBR) and moving bed biofilm reactor (MBBR) are two common wastewater treatment technologies. [0003] Membrane bioreactor (MBR) water treatment technology is a new type of water treatment technology that combines high-efficiency membrane separation technology and activated sludge method. Due to the filtration effect of the membrane, the microorganisms and sludge are completely trapped in the bioreactor, which realizes the complete separation of the hydraulic retention time and the sludge age, so that the biological unit has a high sludge concentration, which not only improves its organic matter. The removal rate, and the removal rate of ammonia nitrogen is also significantly increased. MBR also has the advantages of s...
