Description
Technical field
This utility model belongs to a kind of sewage-treatment plant, more particularly to a kind of stable operation flux large period length, backwash
Dynamic film component of the good low cost of spontaneous operational effect of cycle length and preparation method thereof.
Background technology
At present waste water treating and reutilizing and the conventional process of one-level A discharge are activated sludge process -- the combination work of depth logos
Skill or for membrane bioreactor (MBR).Activated sludge process -- the group technology of depth logos, i.e., live in original denitrogenation dephosphorizing
Property sludge processes on the basis of, increase coagulation, plate-spinning filter, the technique such as sterilization, but the technological process length, equipment is more, floor space
Greatly, stably reaching standard is difficult to indexs such as ammonia nitrogen total nitrogens.Membrane bioreactor (MBR) have floor space is little, effluent quality is excellent, can
The advantages of enhanced biological is processed, China's land used is limited, developed area good market prospect, but MBR techniques are still immature,
Membrane flux is low, high energy consumption, service life are short, limits further genralrlization and uses.
Dynamic Membrane (Dynamicmem-brane) is a kind of emerging sewage disposal film, is by being formed on film base material surface
Sludge blanket plays a kind of new membrane module of accurate crown_interception, and wherein self-forming dynamic membrane is by sludge flco in filter process
(microorganism and its metabolite) is accumulated to form film layer for class coating material.It forms time and thickness and Biomass etc. with operation bar
Part is closely related, has reported in literature sludge flco cumulative speed to be about 0～50g/ (m2H), thus " film layer " forms relatively slow
And it is difficult to stablize, the time is longer to cause Dynamic Membrane to be formed, and generally at 30 minutes to a few houres, thus initial stage water quality is difficult to
Meet and require (effective filtration is only formed to the effect of certain thickness competence exertion in sludge blanket), big capacity of returns can only be adopted
To film forming, so as to increased Qian Dao ponds load；Secondly, Dynamic Membrane operationally increased because film layer easily occurs in high sludge concentration
Hurry up, cause effluent flux to decline, effective cycle of operation is relatively short, and lack effective control measure；Besides, Dynamic Membrane
Backwash effect is poor, and effluent flux recovery rate is low, causes normal aquifer yield little, is easy to produce irreversible membrane fouling after time length, leads
Cause medicine to wash frequently, increased operating cost and complex operation degree.This three big defect becomes the good cost of the spontaneous operational effect of restriction
Low dynamic film component effectively utilizes major obstacle.

Millimeter, internal diameter are 20 millimeters, a height of 0.5 meter.
Used as another kind of improvement, the Dynamic Membrane from outer to inner includes successively Filtration Adsorption layer, anaerobic reaction layer and anti-nitre
Change conversion zone.
This utility model additionally provides the formation and methods for using them of above-mentioned dynamic film component, comprises the following steps：
(1) formation of Dynamic Membrane：Waste water is continued through into base material 1-7 days and forms Dynamic Membrane in substrate surface, specially：
Sewage permeates from outside to inside in base material, while adsorbing the impurity and sludge of some larger particles in substrate surface, forms nascent
Dynamic Membrane；Adsorbing contaminant is continued on nascent Dynamic Membrane surface and sludge forms Filtration Adsorption layer after operation a period of time, dynamic of coming into being
Film is internally formed the sludge blanket of one layer of densification and grows anaerobe and is anaerobic reaction layer, and Dynamic Membrane of coming into being penetralia grows anti-nitre
Change antibacterial and be anti-nitration reaction layer, the base material for so far forming surface attachment Dynamic Membrane is dynamic film component；
(2) wastewater treatment：Sewage flows through Filtration Adsorption layer and filters in Filtration Adsorption layer；Pass through anaerobic reaction layer detesting
There is anaerobic reaction in the presence of oxygen bacterium, the Organic substance of macromole is decomposed；Anti-nitration reaction layer is finally flowed through in denitrifying bacterium
In the presence of, the carbon source provided using anaerobic reaction layer, to denitrogenation of waste water.
In step (1) and step (2), waste water is 0.5-10h by the time in Dynamic Membrane.
In step (1) and step (2), waste water passes through Dynamic Membrane naturally by gravity.
This utility model additionally provides application of the above-mentioned dynamic film component in nitrogenous effluent treatment.
Beneficial effect：Dynamic film component simple structure, the low cost of the good low cost of operational effect that this utility model is provided
It is honest and clean, easy to use, rely on the quick activated sludge cake layer for being formed on macropore base material and complete to separate, denitrification effect is good, can have
