Description
Technical field
The present invention relates to a kind of biomembrance process water treatment technology and equipment, belong to technical field of waste water processing.
Background technology
Biomembrance process waste water treatment process technology mainly is divided into by the way of contact of mikrobe and waste water at present: two kinds of Technologies of biological filter and blodisc.But the weak point of biological filter is that the filter bed volume is big, and occupation of land is many, normal generation obstruction in service, grey fly and foreign odor.The weak point of blodisc is that the rotating disk material is more expensive, and investment is big, and in addition because of no ventilation installation, the oxygen supply of rotating disk relies on the microbial film contact atmosphere of card, and like this, volatile matter will produce pollution in the waste water; Moreover the performance of blodisc receives ambient air temperature and other factor affecting bigger, so when in the north blodisc being set; Generally place indoor; And take certain insulation measure, as be built in outdoor blodisc and all also need add awning, rainwater drip washing prevented so that biofilm detachment.
Summary of the invention
The object of the present invention is to provide a kind of standardized, be suitable for producing in batches novel in aeration tubular fibre biofilm carrier module and application method thereof.The aeration biomembrane carrier module adopts the hollow-fibre membrane of hydrophobic material and collective component thereof to be made in described; Interior aeration biomembrane carrier module comprises the hollow-fibre membrane of some amount and the solid fibre of some amount; They are the curtain shape; Parallel and be spaced, two ends use resin package respectively on collective component.Described hollow-fibre membrane is meant the porous tubular fibre of processing with organic materials, and it has hydrophobic characteristic, and the micropore of One's name is legion is arranged on its perisporium, and gas can be through the side direction opposite side infiltration of the micropore on the tubular fibre perisporium by perisporium.During application; Interior aeration tubular fibre biofilm carrier module is placed the biological culture pond, be assigned to the inner chamber of the hollow-fibre membrane on the biofilm carrier module to air through gas distribution pipe, air is introduced from an end of hollow-fibre membrane; Draw from the other end; Cross in the process of hollow-fibre membrane inner chamber at airflow, the micropore that airborne oxygen sees through on the hollow-fibre membrane perisporium penetrates into the outside of hollow-fibre membrane from inside to outside, thereby makes the microbial film of the growth on the outside surface of hollow-fibre membrane obtain oxygen; Form aerobic biologic membrane; Aerobic biologic membrane, is converted into nitric nitrogen to organonitrogen and ammonia nitrogen simultaneously, and is discharged into metabolic product in the water the carbonaceous organic material oxygenolysis in the sewage through metabolism; The microbial film that adheres on the solid fibre forms the anaerobe film owing to can not get oxygen; The anaerobe film is converted into the organism than small molecular weight such as organic acid to the larger molecular organics in the sewage, helps other mikrobes to utilize these organism; Along with biomembranous growth; Microbial film on the tubular fibre film outer surface is more and more thicker; The speed of consume oxygen is more and more faster; Speed up to its consume oxygen sees through the speed of micropore to exosmosis above the airborne oxygen in the hollow fiber cavity, so just makes biomembranous top layer (corresponding with the tubular fibre film outer surface) anoxic to form certain thickness anoxic microbial film.Anoxic microbial film nitrate transporters in higher and be converted into nitrogen to them from water, thus from water, remove this part nitrogen element.Like this, in same biological culture pond, turn out easy-to-keep biological film, anoxic microbial film and anaerobe film simultaneously, make that organism and the ammonia nitrogen in the sewage obtains removing, and reach purpose of energy saving.
