Embodiment 1

[0027] combine figure 1 , the aerated membrane bioreactor of the present embodiment comprises a water distribution area 1, a treatment area 2 and a water collection area 3, the water distribution area 1 collects sewage, and the treatment area 2 purifies the sewage from the water distribution area 1, and the water collection area 3 Collection and treatment area 2 Collection of purified sewage, in which:

[0028] Water inlet pump 13, water inlet pipe 11 and flow meter 12 are arranged in water distribution area 1. Extending into the treatment area 2, a flow meter 12 is set on the water inlet pipe 11;

[0029] The treatment area 2 is provided with an aeration pipe 21, a ceramic membrane assembly 22, a ceramic membrane aeration vent pipe 23 and a ceramic membrane outlet pipe 24. The aeration pipe 21 is arranged at the bottom of the treatment area 2, and an aeration pipe 21 is provided The trachea electric valve 211, the aeration pipe 21 is also connected with the fan 4, the aerat...

Embodiment 2

[0052] Adopt the reactor among the embodiment 1 to carry out the treatment of domestic sewage, process is as follows:

[0053] The wastewater passing through the water distribution area 1 enters the treatment area 2 through the water inlet pump 13 and the water inlet pipe 11; at this time, the aeration method is perforated aeration in the lower aeration pipe, the ceramic membrane aeration electric valve 231 is closed, and the aeration pipe electric valve 211 is opened; At this time, the ceramic membrane module 22 is used as the filler of the biological contact oxidation process. The biofilm on the filler is aerated by the aeration tube 21. On the one hand, the organic matter in the influent is degraded, and on the other hand, the biofilm is constantly renewed. Wastewater pollutants are removed, and the outlet water enters the water collection area 3 through the outlet pipe 31 from the outflow water.

[0054] Main pollutant index of domestic sewage COD=300mg / L, BOD 5 =200mg / L,...

Embodiment 3

[0057] The wastewater passing through the water distribution area 1 enters the treatment area 2 through the water inlet pump 13 and the water inlet pipe 11. At this time, the aeration method in the treatment area 2 is perforated aeration at the lower part of the aeration pipe, and the ceramic membrane aeration electric valve 231 is closed, and the aeration The pipe electric valve 211 is opened; the activated sludge in the reactor degrades and removes the organic matter in the influent, and the ceramic membrane module 22 at this time further intercepts the pollutants in the water; the effluent is filtered by the ceramic membrane module 22 and enters the ceramic membrane module 22 Inside, at the same time, the outlet water is disinfected through the inner nano-silver substrate, the outlet pump 242 is started, and the outlet water enters the water collection area 3 through the ceramic membrane outlet pipe 24. At this time, the water collection area 3 can be used as a reuse water co...

Abstract

The invention discloses a ceramic membrane and a membrane aeration biologic reactor provided with the same. The ceramic membrane comprises a ceramic membrane supporting body and a separating layer adhering to the ceramic membrane supporting body. The ceramic membrane supporting body is prepared in the way of evenly mixing and stirring 42% by mass of ceramic membrane supporting body powder, 2% by mass of pore forming material, 1% by mass of binder and 55% by mass of sintering aid, and conducting sintering for 8 h at 960 DEG C to obtain a ceramic membrane supporting body; coating the inner surface of the ceramic membrane supporting body with membrane casting solution formed into the separating layer till the surface becomes uniform, and conducting sintering on a dried ceramic membrane coated with the membrane casting solution formed into the separating layer at 800 DEG C to obtain the ceramic membrane supporting body covered with the separating layer. The membrane aeration biologic reactor provided with the ceramic membrane has the functions of a membrane bioreactor, a membrane aeration biologic reactor and a bio-membrane reactor. The membrane aeration biologic reactor provided with the ceramic membrane has flexible operation mode, can save energy and has a good water treatment effect. The functions of a membrane bioreactor are realized, and bio-contact oxidation is realized, so that multifunctional operation can be achieved.

Description

technical field [0001] The invention belongs to the field of environmental protection, and in particular relates to a ceramic membrane and an aerated membrane bioreactor equipped with the ceramic membrane. Background technique [0002] Membrane bioreactor (membrane bioreactor, MBR) is a water treatment process that combines membrane separation technology and biological reaction technology. This process has the advantages of less land occupation and high processing efficiency, so it has developed rapidly in recent years. MBR is mainly composed of two parts: membrane module and bioreactor. The bioreactor can degrade pollutants, and the membrane module can play the role of filtration to further purify water quality. [0003] Membrane aerated bioreactor (MABR) technology is a new process developed and researched for the shortcomings of existing membrane bioreactors. This process has the advantages of less aeration, integration of nitrification and denitrification, The characte...
