Description
Technical field
The present invention relates to a kind of technical field of sewage, more particularly to a kind of effluent purification method.
Background technology
At present, during the dirty water decontamination handles, in order to improve wastewater purifying efficiency, need to be carried out using milipore filter mostly
Precision is filtered, but, milipore filter is easy to seriously polluted, the especially sewage of high concentration in sewage disposal process so that ultrafiltration
Film is contaminated quickly, clean it is cumbersome has to be changed, it is relatively costly due to milipore filter with the quickening of replacement frequency,
So that water process operating cost is increased.
The content of the invention
The present invention in order to solve problem above provide a kind of easy to operate, good purification, adaptability extensively, run into
This effluent purification method that is low, reducing milipore filter load, extend milipore filter service life.
The technical scheme is that：Sewage is passed sequentially through multi-functional nitration denitrification integral type by described purification method
Self-forming dynamic membrane bioreactor, carries out biochemical treatment first；By microfiltration membranes, filtration, purification is carried out；By milipore filter, carry out
Filtration, purification, described self-forming dynamic membrane bioreactor is in column structure, including some self-generative dynamic membrane component units, under
And on be made up of pretreatment reaction area, aeration reaction zone, half aeration reaction zone successively；By perforated plate point between each reaction zone
Every.
Described self-forming dynamic membrane bioreactor is filled out using the hypoxia response or suspension of anoxic reverse-flow type or fixed filler
Material aerobic reaction.
Described self-generative dynamic membrane component unit is made up of PVC support frames, 40 mesh steel-wire screens and industrial nonwoven cloth, institute
The steel-wire screen stated is arranged on PVC support frames, and described industrial nonwoven cloth is arranged in steel-wire screen.
Described self-generative dynamic membrane component unit is tubular structure, and described self-generative dynamic membrane component unit can be inserted into spontaneous
In the jack reserved on bioreactor of dynamic membrane collector pipe.
The present invention gives full play to each reaction zone function, and the fluidised form and fortune of each reaction zone can be realized by changing aeration condition
Effect of line mode, realizes the multi-functional-area of flexible and convenient, so that reactor has two kinds of entirely different operational modes；
Present invention process method can flexibly change the state for the treatment of region according to the characteristics of influent quality, i.e., as contained in influent quality
When having hard-degraded substance, using anoxic reverse-flow type.When processing other kinds of sewage, pretreatment reaction area is changed to fix filler
Hypoxia response area or floating stuffing aerobic reactor zone, so as to realize processing the multifunctional reactor of different influent qualities.
Present invention process method reflux is backflow power using the jet power sum that gravity is produced with water inlet, and is led to
Valve controlling return flow is crossed, the backflow model without additionaling power is realized.
Self-generative dynamic membrane component unit cost is very cheap, and effluent quality is slightly worse than common organic membrane module, with very
Good economic benefit.Meanwhile, compared with general frame self-generative dynamic membrane component, tubular self-generative Dynamic Membrane has under same volume
The big advantage of water-outlet area.And the quantity of self-forming dynamic membrane unit can according to treatment water number and reactor volume and
Freely adjust, total collector pipe has reserved jack, self-forming dynamic membrane unit need to only be inserted or pull out, using it is very flexible,
It is convenient.
The present invention replaces traditional micro-filtration or super using anoxic backflow or aerobic-anaerobic pattern using the nethike embrane of large aperture
Filter membrane, using the sewage layer bioreactor of dynamic membrane produced on film surface in running, successfully processes sanitary sewage, height
Concentration waste water etc., for the removal of nitrogen and hard-degraded substance, then by micro-filtration and ultrafiltration, solves asking for ultrafiltration high cost
Topic, and realize good clean-up effect.
Brief description of the drawings
Fig. 1 is operation principle schematic diagram of the invention.
