Specific implementation mode
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with embodiment and attached drawing to this hair
Bright embodiment is described in further detail.
One) experiment of following embodiment is run parallel using three sets of SBR (R1, R2, R3) reactors, and experiment is reactor used
It is plexiglass box, total measurement (volume) 12L, dischargeable capacity 10L test sludge used and be derived from sewage treatment plant of Wenzhou City oxygen
Change ditch mud mixed liquid, staticly settles after mud-water separation, pour out supernatant and discard the bad sludge of settling property and sunk
Sludge drops.Initial sludge concentration is 4000mg/L after inoculation, and sludge volume is the 20% of reactor dischargeable capacity.The fortune of reactor
Row operating mode is：It is aerated 8h, precipitates 1h, leave unused 1h (stir-activating), and draining is than being 1/3.Wherein, it is added in No. 1 and No. 2 reactors
Magnetic powder and estrogen test for No. 3 and do not add magnetic powder and estrogen as a control group.
Estrogen used is four kinds of typical non-steroidal estrogenics in following embodiment, by German DrEhrenstorfer companies
Production.Magnetic powder used in experiment is Fe3O4, 40-60 μm of the particle size range of magnetic powder.
Sewage used is artificial distribution in following embodiment, with ensure the stability of experiment water inlet and the collimation of experiment and
Accuracy.Water distribution is using sucrose as microbe carbon source, with (NH4)2SO4For nitrogen source.Water distribution routine water quality index is：COD330~
350mg/L；TN30~40mg/L；NH3- N20~30；TP5~6mg/L.Mineral salt solution is added in the another sewage per 1L.It is artificial useless
Adding the four kinds of estrogen solution configured in water, the concentrations of E1, E2, EE2, E3 in water distribution are respectively 2.09~
2.2mg/L, 1.12~1.15mg/L, 2.61~2.7mg/L, 0.56~1.26mg/L.Sewage formula and mineral salt solution formula
See Tables 1 and 2.
Table 1 matches water meter
2 mineral salt solution formula of table
Two) water analysis method
Small column solid phase extraction-GC/MS the technologies of HLB are used to the assay method of four kinds of estrogen in Inlet and outlet water.Water quality is conventional
Refer to object detection method and device therefor is shown in Table described in 3.
The conventional water analysis method of table 3
Three) activated sludge EPS extractions and analysis
Slime, LB-EPS, TB-EPS of activated sludge are extracted, extracting method is centrifugation-excusing from death extraction method.At
Analysis is mainly the analysis of EPS protein and polyoses content, is detected, is adopted to protein content using sulfuric acid-anthrone method
Polyoses content is detected with microplate reader method.
Three-dimensional fluorescence scanning, sweep speed 12000nm/min are carried out using three layers of EPS of fluophotometer pair, wherein are swashed
Hair wavelength is scanned from 200nm to 500nm, increment 5nm；Launch wavelength is scanned from 250nm to 600nm, increment 2nm.With phosphorus
Acid buffer does blank.
Embodiment 1
(1) first, operating mode carries out domestication culture to reactor to activated sludge as described above.To reactor during domestication
It is discharged COD, TP, NH3The removal effect of-N and four kinds of estrogen is monitored, and estrogen was added in second day into reactor
(sludge be just put into reactor on the same day just be added estrogen, may result in activity of activated sludge at once reduce, cause to tame
Failure), since the estrogen in water outlet measure running third day.
Effluent quality of the reactor during domestication is stablized is shown in Fig. 1.Wherein, two figure of a, b is in water inlet containing estrogen
Two SBR；C is control group, that is, does not add the SBR of estrogen in intaking.It will be seen from figure 1 that reactor operation is after a week, three
Sbr reactor device tends towards stability to the removal rate of conventional water quality index, wherein the removal rate highest of COD has reached 97%；TP,
NH3The removal rate of-N is respectively 57.08% and 72.4%；The removal effect of four kinds of estrogen is risen and fallen in reactor, wherein
The removal of tri- kinds of estrogen of E1, E2, E3 is higher, and the removal rate for being all higher than 90%, EE2 is minimum, and highest removal rate is only 48%.
(2) after a week, effluent quality indices tend towards stability reactor, start to add into reactor in the tenth day
Magnetic powder, magnetic powder concentration are set as：0.05mg/L,0.1mg/L,0.5mg/L,1mg/L,2mg/L.Under each magnetic powder concentration, detection
3 days effluent qualities of reactor, are averaged, and observe the removal effect of indices.
The specific removal situation of four kinds of estrogen is shown in Fig. 2 in waste water under different magnetic powder concentration.Waste water under different magnetic powder concentration
The removal effect of every routine water quality index is shown in Table 3.COD is larger in the front and back removal effect of magnetic powder load, may be mainly
Sludge activity is higher in reactor, and dissolved oxygen is sufficient, being capable of carbon fully in Decomposition Wastewater in growth of aerobic microorganisms reproductive process
Source.Under 5 different magnetic powder concentration, with the removal rate highest of TP under 0.1g/L concentration, the NH under 1g/L concentration3The removal of-N is imitated
Fruit is best, is all higher than TP and NH when not adding magnetic powder3- N removal effects.Wherein, the removal rate both when 1g/L obtains
It improves, removal rate has been respectively increased 8.2%, 10.1%, has illustrated that the addition of magnetic powder promotes activated sludge to TP, NH in water3-N
Removal.
Fig. 3 gives the removal effect of the different lower four kinds of estrogen of magnetic powder concentration.Method provided by the present application removes E1
Except rate effect is not greatly improved compared with conventional method.But the removal rate of E2, EE2, E3 increase, wherein with estrogen EE2
Removal effect raising become apparent.It can be seen from the figure that removal rate best results of the EE2 in the case where magnetic powder is 1g/L concentration,
44.64% is improved compared with the removal rate before load magnetic.Initial stage concentration is added in magnetic powder, EE2 removal rates are relatively low, with the increasing of concentration
Add, removal rate is in rising trend.In addition, E2, E3 removal rate highest when magnetic powder amount is 0.1g/L, before not loading magnetic powder respectively
Improve 10.94% and 6.13%.
In addition, also being analyzed the EPS layerings component for adding activated sludge after magnetic powder.Tri- figure of a, b, c of Fig. 4 is distinguished
Give the content situation of albumen and polysaccharide in Slime, LB-EPS, TB-EPS component under different magnetic powder concentration.Compare difference
EPS situations of change under magnetic powder concentration.It is on a declining curve to can be seen that Slime layers of protein content from a in Fig. 4, and it is more
Sugared content is in first to rise to decline afterwards with the increase of magnetic powder concentration.From the b in Fig. 4 can be seen that albumen in LB-EPS with
The trend fallen after rising is presented in polysaccharide, and content of the two under 0.5g/L magnetic powder concentration is highest.It can be with from the c in Fig. 4
Find out, the polysaccharide of TB-EPS and the content of protein are also as the increase of magnetic powder concentration is in first to rise to decline afterwards, wherein two
Person is using the content at 0.1g/L as highest.May be to promote active dirt because adding for magnetic powder keeps sludge flocculation structure close
The formation of microorganism flco in mud, the content of organic matter increases in sludge EPS, so as to preferably with the pollutant knot in water
It closes, and being settled down in bed mud enables pollutant to remove.
In addition, also to different magnetic powder dosages when activated sludge EPS three-dimensional fluorescence characteristic studied, as a result send out
Existing, after magnetic powder adds, larger change has occurred in two albuminoid peaks of LB-EPS and TB-EPS, while humic acid peak occurs
With fulvic acid peak, also, when the two fluorescence intensity is higher, the removal rate of estrogen EE2 is also higher, illustrates two substance contents
The removal for being present in EE2 is extremely related.It further illustrates, adding by magnetic powder in method provided by the present application keeps sludge dense
Degree greatly improves, and larger molecular organics matter content is improved in EPS, and then improves pollutants removal rate.
