Description
Technical field
The present invention relates to a kind of sewage water treatment method and equipment thereof, particularly a kind of method and equipment thereof of integrated sequencing-batch formula treating sewage by plant micro-net dynamic membrane.
Background technology
Membrane bioreactor (Membrane bioreactor, MBR) because its wastewater treatment efficiency efficiently, operating method adopts in sewage treatment process in a large number flexibly, and the MBR Technology is ripe to be applied in the treatment project of various sewage.Yet MBR also exists the membrane module material cost too high relatively, and part integral type and separated type MBR rely on suction pump suction water outlet to cause operation energy consumption to cross high technical problem.Given this, development of new high performance membrane bio-reactor is one of MBR technological development direction.Mardinkowsky found that the sludge blanket that is retained in the film surface can cause the rising of film pressure and the quick minimizing of membrane flux in 1966 in operation MBR process, but the efficient of holding back to the small molecules suspended solids increases, analysis may be that the sludge blanket of holding back has crown_interception to the small molecules suspended solids, simultaneously this process since this sludge blanket in MBR generation in service, as replace the microfiltration membrane of MBR membrane module with the wide aperture screen cloth, its Financial cost reduces greatly, (Dynamic Membrane Bioreactor DMBR) produces bioreactor of dynamic membrane thus.
Compare with traditional MBR, DMBR can rely on head difference (Water head drop, WHD) gravity flow water outlet, saving operation energy consumption; The water outlet Dynamic Membrane flux of DMBR improves a lot than MBR simultaneously, produces water efficient and greatly improves; Compare with MBR, the cleaning of DMBR Dynamic Membrane is easy, simple to operate, relies on air water to unite flushing and can realize almost 100% clear water membrane flux, and Dynamic Membrane is online generation in operational process that Dynamic Membrane regeneration easily, compare with traditional MBR micro-filtration membrane module, DMBR has alleviated the loss of membrane module greatly, and prolong work-ing life, has considerable economy and practicality.
Domestic and international at present formation mechanism at DMBR, influence factor, the DMBR operation stability, the economy of DMBR technology, DMBR membrane module film base material material performance etc. has been carried out big quantity research.The non-woven fabrics that people such as Seo utilize the polypropylene material has reached 93.5% and 91.6% for the DMBR of film base material material respectively to the SS of sanitary sewage and the clearance of COD; The DMBR that people such as Moghaddam utilize polynary fat non-woven fabrics to make for the film base material material has reached 87% to the TOC clearance of sewage; People such as Altman study the filtration mechanism of DMBR, think membrane matrix compactness extent height, and the Dynamic Membrane separation performance is good; Fan Bin etc. utilize DMBR that common bolting silk material the makes NH to sanitary sewage
4 +-N clearance has reached 96%; Zhang Jian etc. utilize macropore microgrid material to handle for the DMBR of film base material material interrupts waste water to papermaking straw pulp; Ice waits and utilizes DMBR that filter cloth makes COD and the NH to sewage just
4 +The clearance of-N has reached 72%-89% and 66%-94% respectively.
Though DMBR has advantage than MBR in several respects, also exist several respects problem to remain to be furtherd investigate.The DMBR production process causes that easily mud leaks, and its initial water outlet often can not be up to standard; Though both at home and abroad to DMBR dispose of sewage effect and influence factor research experiment, the Dynamic Membrane filtering layer remains unified to the result of the removal mechanism of different-grain diameter pollutent; Lack detailed analysis simultaneously to the DMBR economy, so as for future DMBR practical application reference is provided; The DMBR film base material material of having reported mainly contains materials such as non-woven fabrics, filter cloth, nylon screen, Stainless Steel Cloth, and the film base material material of development of new efficient economy also is an aspect that improves DMBR research and applicability; Experimental stage DMBR technology is single at present, lacks DMBR and other technology, as SBR, and A/O, A
2/ O, the composite test of EBPR etc. to improve the removal effect of DMBR to nitrogen, phosphorus in the sewage, promotes DMBR technology and DMBR combination process using value in sewage disposal.
