Abstract
The utility model relates to a sucking built-in film biological reactor which belongs to water treating equipment. The film biological reactor is composed of a reaction pool, a film assembly, bafflers, aerator pipes and an effluent water suction pump. The film assembly is arranged in the reaction pool, the lower part of the film assembly is provided with a plurality of aerator pipes, and air outlet holes are arranged on the aerator pipes; the both sides of the film assembly are provided with the bafflers, and the film assembly is connected to the effluent water suction pump. The water quality of domestic sewage after treatment by the film biological reactor of the utility model is good, standards of recycle reclaimed water prescribed by China can be achieved, and the utility model has advantages of convenient operation and long operating periods.
Description
The utility model relates to membrane bioreactor, belongs to the water treating equipment field.
Traditional reusing sewage technology generally is to increase tertiary treatment technologies such as coagulation, filtration, sterilization on the basis that common two stage biological is handled, and this technical process is tediously long, floor space is big, operational administrative is complicated, and its effluent quality is also stable inadequately simultaneously.In addition, because current drinking water source is polluted day by day, some materials that cause harm humans health such as prominent, carcinogenic are on the increase in the tap water, traditional coagulation, filtration, disinfectant drinking water treatment technology are perfect inadequately, be badly in need of replenishing, and the membrane Bio-reactor Technology that development in recent years is got up makes above-mentioned two aspect technology enter a brand-new field.The essence of this technology is to substitute traditional gravity type boat davit solid-liquid separation technique with membrane separation technique, and technical process is greatly simplified, and has overcome the shortcoming and defect of traditional technology, makes system's stable effluent quality reliable.
And begun now the membrane bioreactor used, and being generally pressurization separated type system (see figure 1), 1 is bio-reactor among the figure, and 2 is membrane module, and membrane module mostly is flat and tubular type, and is placed in the bio-reactor outside.It is short that this system energy consumption height, membrane module structure complexity, facility investment are greatly, film stops up the serious cleaning interval, the operational management complexity.
At existing many problems in the above pressurization separated type system, the purpose of this utility model is to provide a kind of energy consumption lower, and flow process compactness, membrane module simple cheap, operational management be the new membrane bio-reactor easily.
The utility model membrane bioreactor is made up of reaction tank, membrane module, flow deflector, aeration tube and several parts of water outlet suction pump.Membrane module is an organic membrane, general available hollow-fibre membrane, and membrane module is placed in the reaction tank, places a plurality of aeration tubes in the membrane module bottom, has production well on the aeration tube, with bubbling air in reaction tank.In the membrane module both sides flow deflector is set, buoyance lift so that the bubble that is come out by aeration tube can make progress in an orderly manner.On membrane module, connect and aspirate out water pump, will aspirate away by the water behind the membrane filtration.
Illustrate that accompanying drawing is as follows:
Fig. 1 is pressurization separated type system membranes bio-reactor synoptic diagram.
Fig. 2 is built-in membrane bioreactor synoptic diagram for the utility model aspirates.
Accompanying drawings embodiment is as follows:
Fig. 2 is built-in membrane bioreactor synoptic diagram for the utility model aspirates, and wherein 3 is reaction tank, and 4 is membrane module, and available hollow-fibre membrane is to handle sanitary sewage 10m day
3/ day is an example, and the tubular fibre membrane area is 48m
2, the volume of reaction tank (1) is 2.5m
3, at membrane module (4) positioned beneath aeration tube (5), bubbling air in the aeration tube (5) is so that the turbulent fluctuation on required oxygen of biological treatment and increase film surface to be provided, to slow down the obstruction of film.Flow deflector (6) is settled in both sides at membrane module, so that the bubble that is come out by aeration tube (5) can rise and control water mobile direction along film in an orderly manner.Connect on membrane module (4) and aspirate out the water pump (not shown), the water after will being filtered by membrane module (4) is extracted out.Going out water pump is periodic running, and its cycle can be out 13 minutes and stopped 2 minutes.
Sanitary sewage water quality after employing the utility model Membrane Bioreactor for Wastewater Treatment is good, meets state specified standards, and cycle of operation while is long, can reach more than half a year, and several times of general separated type system head make operation greatly convenient.Its effluent quality can reach the middle water reuse standard of national regulation.
