Algae.
Below by specific embodiment, the present invention is further described.
Embodiment 1
The wawter bloom Microcystis aeruginosa (more than 90% phytoplankton is microcystis kutz) gathered using summer Lake Taihu, by 0.45
The suspension that Taihu Lake raw water after μm membrane filtration is configured to low algae cell density (OD680 0.2) again is experiment algae kind, and
Laboratory carries out removing algae effect experiment.
(1) take the above-mentioned algae suspensions of 200mL to be placed in 400mL beakers, be ultrasonically treated 5,10,30,60 and 300s, ultrasound intensity
0.0353W/mL is set to, supersonic frequency is set to 35kHz, and temperature maintains 25 DEG C, sets blank control group in addition.Then by algae sample
Uniformly go in four colorimetric cylinders, be placed in quiescent culture in bio-incubator.Culture light intensity is 30 μm of ol (photons) m-2s-1,
Temperature is 25 DEG C, Light To Dark Ratio 12h：12h.Each of the above processing setting three is parallel, and averages.Take respectively at each ultrasound
Algae suspension after the foster 20s of reason tissue culture determines its Chlorophyll-a Content；The sample for wherein cultivating 0s takes 50mL to be shaken up after supersound process
Algae solution determines in time；And remaining algae sample takes layering to determine, that is, upper strata 45mL algaes suspension is taken as suspension or floating frustule leaf
Green plain a contents, bottom 5mL algae solutions are as sedimentation frustule Chlorophyll-a Content.Calculate Chlorophyll-a Content vertical distribution ratio.It is super
The equal quiescent culture 20s of each group after sonication, the rate of settling according to colorimetric cylinder length computation each group frustule is (under being equivalent at the uniform velocity
It is heavy).
(2) take the above-mentioned algae suspensions of 50mL to be placed in colorimetric cylinder to be ultrasonically treated, sonication treatment time is arranged to 5,30 and
300s, ultrasound intensity, which is set, includes 0.0206,0.0353,0.0433W/mL, supersonic frequency is set to 35kHz, and temperature maintains 25
DEG C, blank control group is set in addition, and every group three are parallel.The equal quiescent culture 20s of each group after supersound process, then take bottom 5mL algaes
Liquid, measure OD680 (characterizes frustule concentration), and calculates clearance (=(the raw water OD680- supernatants of algae in water sample
OD680)/raw water OD680).Upper strata 45mL algae suspensions are taken, the OD440 of supernatant is determined after centrifugation, and pass through blood counting chamber pair
Wherein complete cell is counted, and (by contrasting 35kHz, 0.0353W/mL is ultrasonically treated lower supernatant OD440 measure knot
The count results of fruit and blood counting chamber find that OD440 can characterize the rupture event of frustule well, are specifically shown in Table 1).
The frustule rupture rate of two kinds of evaluation indexes under 1 different sonication treatment times of table
As shown in figure 1, in experimentation, most frustules of control group are floated or are suspended in water column；Ultrasound
The algae suspension of processing is after 20s quiescent cultures, and water column Determination of Chlorophyll clearance changes with the change of processing time, wherein at 5s
The clearance of reason group is maximum (88%)；And the algae rate of settling now is 0.52cm s-1 (Fig. 2), actual heavy algae can be drawn accordingly
The Best Times that algae settles in pond are (heavy algae tank depth (H) × 103/0.52) s, so as to calculate the heavy algae pond number that should be designed
Amount.In summary, the algae that this device can be effectively gone in water removal, and optimal ultrasound parameter is：Supersonic frequency is 35kHz, is surpassed
Sound intensity is 0.0353W/mL, ultrasonic time 5s.This is visible, proposed by the invention that original tap water is carried out with ultrasonic wave
The method of advanced treating, it is simple to operate, it is easy to accomplish, the purpose for efficiently removing algae in raw water can be reached, can preferably be expired
The water demand of sufficient waterworks.
From the figure 3, it may be seen that with the increase of ultrasound intensity and the extension of ultrasonic time, frustule rupture rate increases therewith
Greatly, but there is not the phenomenon ruptured in ultrasonic 5s, frustule under ultrasound intensity 0.0206,0.0353W/mL.Three kinds of ultrasounds are strong
Under degree during processing 5s, the clearance of algae is maximum, and the clearance under wherein 0.0353W/mL processing has reached 88%, but with processing
The extension of time, removal efficiency show the trend (Fig. 4) reduced.Consider the rupture event of frustule and the removal of algae
Effect, it has been found that it both can guarantee that frustule will not rupture and discharge intracellular inclusion when 5s is ultrasonically treated under 0.0353W/mL,
And can efficiently removes the algae in raw water simultaneously.
The existing document except algae aspect have much on ultrasound condition optimization, effect optimization, but do not account for into
Row practical application, also there is the invention of the technology except algae, but these inventions often do not reach good treatment effect, and do not examine
Consider to apply and raw water containing algae is carried out on further treatment technique in waterworks；The present invention is best except algae effect by selecting
Ultrasound condition, devise it is a kind of it is new remove algae pipeline, it can reach homogeneity, continuity processing to raw water containing algae, and can protect
Card frustule will not rupture and discharge noxious material (such as Algae toxins), while on the basis of high removal efficiency is reached, obtain
The optimal sedimentation time, so as to devising above-mentioned ultrasonic wave depth algae-removing device.
