AFM active filter has following 4 outstanding features:
(1) strong adsorption
Ordinary filter retains the process of suspended matter, generally must be by molecule to " conveying " of filter material surface and in filtrate
" attachment " two stages on surface can be only achieved.That is the particle to suspend in water must be first sent to filtering material particle
Then surface could be retained by filtrate.And AFM active filter surface has charge, has been formed on its surface different charge layers,
Can be by the active force between charge particle when particle is close to filtrate " absorption " in filter material surface, increase adsorption plane
Long-pending and adsorption strength.
(2) long service life
Currently, the filtrate in oil field extracted water for filtering technique mainly has quartz sand, anthracite, magnetic iron ore, walnut shell etc..
According to statistics, it will be replaced, be had every 2-3 according to the filtering filtrate at the different disposing polluted water in oil stations of filtrate pollution level
It will even replace within 1 year, and cause the increase of sewage treatment expense and the serious pollution of environment.And AFM active filter is due to it
In operation process, greasy dirt and suspended particulates are attached to the covering film surface of filtrate, do not contact with filtrate itself, not only from root
On prevented attachment of the bacterium on filtrate, while reducing the percentage of damage of filtrate, extend the service life of filtrate.Common filter
Material is with the state vs before and after the use of AFM active filter referring to Fig. 9.
The excellent properties of AFM active filter can also be verified in the comparative experiments in laboratory.With 25kg oil content
It is filtered for the oily wastewater of 50mg/L, takes 20 grams of upper layer filtrate to be placed in a beaker after the completion of filtering and be put into (105 ± 1) DEG C
4 h of drying in oven.Taking-up, which is put into drier, puts to room temperature, measures a small amount of blank gasoline and repeatedly rinses the oil after drying
Sand, the gasoline after flushing are collected in the colorimetric cylinder of 50 mL.Then, oil-sand is poured into the funnel equipped with filter paper, with blank vapour
Oil flushing is until the gasoline color and blank gasoline solid colour filtered out after flushing.Gasoline after flushing is closed at into above-mentioned 50 mL
Colorimetric cylinder in, and be diluted to scale.If being diluted to 100 mL more than 50 mL.According to oil-containing in SY/T 5329-1994
It is 2.5mg/g that the test method of amount, which measures oil content,.Then it is backwashed under same flow velocity, is stopped when backwashing 10 minutes
Backwash opens filter tank and takes upper layer filtrate 20g respectively, then measures three kinds of filtrates respectively according to above-mentioned method with blank gasoline
Oil content are as follows: walnut shell 0.8mg/g, diamond dust 0.5mg/g, nano modification filtrate are 0.15mg/g.Laboratory experiment card
It is filtrate floating 20% to 30% that bright AFM active filter, which most preferably backwashes condition, is continuously backwashed under the conditions of best backwash
The breakage rate of filtrate is less than 3% at 1000 hours.
Scene is by backwash 10 minutes daily, and the service life of AFM active filter is for 15 years.(3) influent quality is wanted
Ask low
" double 50 " oil content of wastewater≤50 ㎎/L, suspended solids content≤50.0 ㎎/L, water outlet can reach level-one water gauge for water inlet
Quasi- " oil content of wastewater≤5 ㎎/L, suspended solids content≤1.0 ㎎/L, suspended particle median diameter≤1.0 μm ".
The moisture film of one layer of hydrophilic and oleophobic type can be generated after the chance water of AFM active filter surface.AFM active filter is in its operation
Cheng Zhong, greasy dirt and suspended particulates are attached to the covering film surface of filtrate, do not contact with filtrate itself, and filter will not be more entered with water flow
Material is internal, causes the pollution of filtrate, has prevented attachment of the bacterium on filtrate from the root.In backwash, greasy dirt, microactuator suspension
Grain is easy to disengaging filtrate absorption under the driving of backwashing water and filter tank is discharged through sewage draining exit, while reducing the broken of filtrate
Rate extends the service life of filtrate, reduces the pollution to environment.
(4) energy-saving and water-saving is backwashed
Ordinary filter filtering is located against porosity between filtering material particle and particle to retain greasy dirt and suspended particulates, allow greasy dirt with
Suspended particulates are attached to filter material surface to realize expected filter effect.However attachment when thus causing filtrate backwash
Object is difficult to the phenomenon that being detached from filtrate.And after new A FM active filter contacts water, surface will form one layer of smooth covering
Film, since its surface can be adsorbed on the suspended particulates of retention on this layer of smooth cover film with charge, so as to avoid oil
Contact of the dirty and suspended particulates directly with filtrate.It is easier that greasy dirt is allowed to reach with suspended particulate disengaging cover film when backwashing in this way
Preferable backwash effect.
Experiments have shown that novel nano modified filter material only needs 5-8 minutes when backwashing, the removal rate of filter material surface greasy dirt is up to 95%
More than, and ordinary filter backwashing time then needs 10-20 minutes, and the oily waste degradation rate of filter material surface is up to 80%.Backwashing time
Reduction electricity consumption and water consumption is greatly saved, save 50% or more backwash water consume on year-on-year basis, save 50% or more on year-on-year basis and recoil
Wash energy consumption.
