Background technology
Membrane bioreactor (MBR) combines membrane separation technique with biologic treating technique, when effectively removing pollutent, also living weight has been trapped in the reactor drum, has overcome the phenomenon that living weight runs off in the traditional biological treatment technology.Difference according to types of bioreactors; MBR can be divided into aerobic MBR and anaerobism MBR; It is low that wherein aerobic MBR is mainly used in organic loadings such as municipal wastewater; The waste water that biodegradability is higher, and for the higher trade effluent of organic loading, use owing to expending too high being difficult to of cost in its aeration process.By contrast, anaerobism MBR more is applicable to the processing of high concentrated organic wastewater because of the lower advantage of its energy consumption.In general, anaerobism MBR reactor drum is made up of the membrane module of a bio-reactor and an external placed type, because the sludge concentration in the anaerobic biological reactor is higher; Long-time running membrane module surface is prone to the accumulation dirt; Cause the film contamination phenomenon, make the MBR treatment effect descend, meanwhile; In the process of cleaning the film pollution, need often to adopt pharmaceutical chemicals, be easy to cause secondary pollution.
Summary of the invention
It is little to the purpose of this invention is to provide a kind of floor space, saves the equipment working cost, but treatment of high concentration organic waste water and can effectively alleviate the external placed type anaerobic membrane bioreactor of film pollution situation.
External placed type anaerobic membrane bioreactor of the present invention comprises equalizing tank, anaerobic biological reactor and film case, and the bottom of anaerobic biological reactor is provided with water distributor; Triphase separator is equipped with on top, and the top is provided with the air outlet, and there is sludge circulation pump the anaerobic biological reactor outside; The import of this sludge circulation pump all links to each other with anaerobic biological reactor with outlet; Microporous aeration device is arranged at the bottom of film case, and the top is provided with venting port, and ultrafiltration pencil membrane module is equipped with in inside; The top of ultrafiltration pencil membrane module links to each other with second suction pump; Equalizing tank links to each other with the water distributor of anaerobic biological reactor through first suction pump, and the rising pipe of anaerobic biological reactor links to each other with the water inlet pipe of film upper box part, and the waste pipe of film lower box part is communicated with the water distributor of anaerobic biological reactor through recycle pump.
Said ultrafiltration pencil membrane module can adopt bundle formula ultrafiltration hollow-fibre membrane among the present invention, and the film surface-area is 0.07m
2
Triphase separator is housed in the anaerobic biological reactor, can effectively the liquid phase in the anaerobic biological reactor, gas phase and solid phase be separated, reduced the sludge concentration of anaerobic biological reactor water outlet, slowed down the film contamination phenomenon.
The anaerobic biological reactor outside is connected to sludge circulation pump, reaches the well-mixed state of muddy water through the waterpower turbulent flow in the working cycle.
Carrying out along with membrane filtration processes; The organic concentration of waste water rises gradually in the film case; Be the organic concentration of waste water in the controlling diaphragm case; The waste pipe of film lower box part is communicated with the water distributor of anaerobic biological reactor through recycle pump, can makes high-concentration waste water and mud in the film case be back to the anaerobic biological reactor circulating reaction.
Microporous aeration device through film case bottom in the membrane filtration processes continues to feed nitrogen, to wash away the mud that accumulates on the ultrafiltration pencil membrane module, decelerating membrane pollution situation.
The advantage of apparatus of the present invention is:
This reactor drum can effectively prevent sludge loss, improves mud mud age, is easy to the enrichment of mikrobe.Wash away through nitrogen and can effectively alleviate the film pollution situation, improve the life cycle of membrane module, save the secondary pollution that causes in cost and the cleaning process of rinsing membrane module.This reaction unit is simple in structure, and easy handling is applicable to the processing of high concentrated organic wastewater.
