Principle of work of the present utility model is as follows:
Sewage enters anaerobic fermentation tank 3 by water inlet pipe 4 and carries out anaerobic treatment, during the fermentation, is trapped within upper gallery 13 part of agitating vane 1, is distributed in fermentation unit with agitating vane in the scum silica frost uphill process of generation.When whipping process starts, agitating vane carries out slow rotation (rotating speed is not higher than 30 revs/min), its centrifugal force is not enough to allow the scum silica frost on blade depart from, therefore, the microorganism of scum silica frost and upper attachment thereof will be rotated with blade, blade sense of rotation 15, water (flow) direction 16 as shown in Figure 6, with the waste water of different positions in system, carry out the removal of organic pollutant.When system will get rid of scum silica frost, agitating vane starts high-speed rotation (rotating speed is not less than 120 revs/min), due to the effect of centrifugal force, scum silica frost will be thrown to outside gallery type blade, under the acting in conjunction of centrifugal force and buoyancy, scum silica frost will export 6 by scum silica frost and float in scum silica frost receiving tank 7, by external mechanical system or manually remove, sediment will sink to the sediment district 10 at the bottom of tank, got rid of by shore pipe 8, and sewage will continue to stay middle layer 11, after process, sewage is got rid of from rising pipe, biogas enters sludge gas collecting device by via collecting methane pipe 9.
The utility model structure stirs and slagging-off by regulating the rotating speed of stir shaft to control, during low speed rotation (rotating speed≤30 rev/min), fermentation system is in the state of being uniformly mixed, during high speed rotating (rotating speed >=120 rev/min), fermentation system is in slagging-off state, scum silica frost will be got rid of by scum silica frost outlet, be stored in scum silica frost receiving tank.
embodiment 2
A kind of whipped-up structure of gallery oar blade type, the primary member of device has agitating vane 1, stir shaft 2, water inlet pipe 4, rising pipe 5, anaerobic fermentation tank 3, scum silica frost outlet 6, scum silica frost receiving tank 7, shore pipe 8, collecting methane pipe 9, in device, the interval of anaerobically fermenting is mainly divided into sediment district 10, middle layer 11, scum silica frost district 12.
The propeller-blade section of the utility model whipped-up structure is waviness, and be divided into gallery 13 and lower gallery 14, wherein a kind of optimization design is, agitating vane vertical height h is 500mm, can determine according to reaction vessel size, and its length to height ratio L/h is 4.0, upper gallery arc radius r
1be 0.75 with h ratio, center of arc angle α gets 60
ο, lower gallery arc radius r
2be 0.6 with the ratio of h, center of arc angle β is 60
ο, the horizontal sextant angle γ of gallery transition section is 45

1get 2/3 of fermentor tank overall height H, blade is installed employing and to be rigidly connected measure, and blade and horizontal sextant angle θ are 15
ο, agitating vane installs 8 layers, installs 6 for every layer, and the radius-of-curvature that blade overlooks face circular arc type medullary ray is 3.5 times of anaerobic fermentation tank radius, agitating vane edge apart from fermentation unit inwall apart from being 300mm.Because agitating vane size is comparatively large, and the horizontal sextant angle θ of agitating vane is less, and this kind of blade more easily tackles the scum silica frost of more floatings, and the bacterial classification in scum silica frost and microorganism are distributed on blade with scum silica frost.Blade is more, and the large percentage that vertical distribution height accounts for, therefore it is distributed more widely in whole fermentor tank, allows the bacterial classification in scum silica frost have more multimachine can react with the middle layer even sewage of sediment layer.
When stirring, the rotating speed of stir shaft 2 is controlled at 10 revs/min, the centrifugal force of this kind of stirring velocity can not allow the scum silica frost retained depart from the gallery of pulpboard blade, meanwhile, due to corrugated blade form, when making blade stirring, the easier eddy current (as shown in Figure 6) forming upward and downward and rotate around blade of sewage, microorganism in the scum silica frost retained with blade contacts more fully, improves stirring efficiency, saves energy consumption.
embodiment 3
A kind of whipped-up structure of gallery oar blade type, the propeller-blade section of the utility model whipped-up structure is waviness, be divided into gallery 13 and lower gallery 14, wherein a kind of optimization design is, agitating vane 1 vertical height h is 200mm, can determine according to reaction vessel size, its length to height ratio L/h is 2.5, upper gallery 13 arc radius r
1be 0.5 with h ratio, center of arc angle α gets 45
ο, lower gallery 14 arc radius r
2be 0.5 with the ratio of h, center of arc angle β is 45
ο, the horizontal sextant angle γ of gallery transition section is 30
ο.This kind of design is based on slagging-off, and when mounted, agitating vane can increase packing density (as shown in Figure 5) in scum silica frost district, the distance H of agitating vane 1 vertical distribution
1get 1/2 of fermentor tank overall height H, agitating vane 1 is installed employing and to be rigidly connected measure, and agitating vane 1 and horizontal sextant angle θ are 20
ο, agitating vane 1 installs 6 layers, installs 4 for every layer, and the radius-of-curvature that agitating vane overlooks face circular arc type medullary ray is 2 times of anaerobic fermentation tank radius, agitating vane 1 edge apart from fermentation unit inwall apart from being 200mm.Because agitating vane is installed more in scum silica frost district, and blade is relatively little, and this kind of blade form is more conducive to the use of the slagging-off when scum silica frost stirs.When removing the gred, the rotating speed of stir shaft is controlled more than 150 revs/min, now, the centrifugal force of the scum silica frost in agitating vane is greater than the frictional force of blade, scum silica frost can along with the guiding of blade gallery, to fermenting container inwall motion (as shown in Figure 5), when scum silica frost departs from agitating vane, during touching inwall, due to the relation of buoyancy, scum silica frost will move upward, simultaneously again due to the effect of centrifugal force, scum silica frost will along container radial outward movement, under both comprehensive actions, time near scum silica frost outlet, scum silica frost will along outlet conduit automatic stream receiving tank, the sediment that density is larger then can descend precipitation, sewage is stayed in container, thus realize the separation of scum silica frost.This kind of structure separation scum silica frost efficiency is higher, and can according to circumstances control at any time, flexible and convenient to use.
Obviously; those of ordinary skill in the art is according to grasped technical knowledge and customary means; according to above said content, can also make the various ways not departing from the utility model basic fundamental thought, these pro forma conversion are all within protection domain of the present utility model.
