Description
Technical field
The utility model relates to a kind of waste disposal plant, is specially ring type filler iron denitrification treatment tank.
Background technology
Utilize filler iron to carry out the denitrogenation processing of sewage, be widely used, but in reaction tank pond, filler iron is placed directly in pond, easily deposits, and is placed in filler frame and drops in pond, because filler is too concentrated, sewage contacts with filler with mud also and reduces, and has reduced reaction efficiency.In addition, the waste water of processing is from discharging and enter settling tank in reaction tank, and a large amount of mud is also discharged thereupon, so also need the sludge part in settling tank to be back in reaction tank.
Utility model content
For above-mentioned technical problem, the utility model provides a kind of reaction unit, and sewage, mud and filler iron can fully be contacted, and the problem of avoiding filler iron to deposit in denitrification process, and concrete technical scheme is:
Ring type filler iron denitrification treatment tank, comprises columniform outer pond, and lid is arranged at Wai Chi top; Annular stuffing sandwich is installed in outer pond, and stuffing sandwich is made up of Double-level Reticulated, is filled with catalysis iron filler in the middle of Double-level Reticulated; The bottom of stuffing sandwich is arranged on outer pond inwall by annular lower clapboard, between outer pond and stuffing sandwich, lower clapboard, lid, surround an annular region, annular region is separated into upper annular region and lower annular region by upper spacer, described upper annular region is exhalant region, described lower annular region is inhalant region, there is water inlet pipe inhalant region, and there is rising pipe exhalant region; The region that described annular stuffing sandwich surrounds is reaction zone, in described reaction zone, has stirring rake; In described outer pond, be sludge settling district below lower clapboard, have sludge agitation oar in sludge settling district, mud relief outlet is arranged at bottom, sludge settling district.
Described stuffing sandwich is two semi-cylindrical compositions, a ring packing interlayer of two semi-cylindrical compositions, and between two semi-cylindricals, space is left in junction.
Described water inlet pipe has multiple, is evenly distributed in inhalant region.
Sewage, in water inlet pipe enters into the inhalant region of annular region, enters in reaction zone by stuffing sandwich, after having intake, open at stirring rake, sewage in reaction zone is stirred, allow sewage again enter in annular region by stuffing sandwich, stop stirring rake, sewage backflow is through stuffing sandwich, get back to reaction zone, again start stirring rake, so circulation, allow sewage and mud repeatedly by stuffing sandwich, react with filler iron in stuffing sandwich.In the time that sludge concentration is lower, open sludge agitation oar, the sludge stirring of bottom, other places is mixed with sewage and improves sludge concentration, need to from treating pond, not carry out again sludge reflux and supplement.Lower water intake mode can also rinse the filler of stuffing sandwich bottom, prevents filler alluvial in stuffing sandwich.
The ring type filler iron denitrification treatment tank that the utility model provides, can fully improve the contact between mud, sewage and filler, improves processing efficiency, and can prevent filler alluvial; Can self provide in addition mud to supplement, need in settling tank, not carry out sludge reflux.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is cross-sectional structure schematic diagram of the present utility model.
Embodiment
Accompanying drawings embodiment of the present utility model, as shown in Figure 1, ring type filler iron denitrification treatment tank, comprises columniform outer pond 1, lid 7 is arranged at 1 top, outer pond; The stuffing sandwich 2 that the interior installation in outer pond 1 is annular, stuffing sandwich 2 is made up of Double-level Reticulated, is filled with catalysis iron filler 8 in the middle of Double-level Reticulated; The bottom of stuffing sandwich 2 is arranged on outer pond 1 inwall by annular lower clapboard 4, between outer pond 1 and stuffing sandwich 2, lower clapboard 4, lid 7, surround an annular region, annular region is separated into upper annular region and lower annular region by upper spacer 3, described upper annular region is exhalant region 200, described lower annular region is inhalant region 100, there is water inlet pipe 11 inhalant region 100, and there is rising pipe 12 exhalant region 200; The region that described annular stuffing sandwich 2 surrounds is reaction zone 300, in described reaction zone 300, has stirring rake 5; In described outer pond 1, be sludge settling district 400 below lower clapboard 4, have sludge agitation oar 6 in sludge settling district 400, mud relief outlet 13 is arranged at 400 bottoms, sludge settling district.
Intake by circular pattern, can fully make sewage contact with the interior filler of stuffing sandwich 2, the mode of below water inlet, be that sewage enters from stuffing sandwich 2 lower annular regions, can utilize the filler in water impact stuffing sandwich 2, in case the filler of stuffing sandwich 2 bottoms is because own wt deposition, or filler deposits and causes filler to lose efficacy in stuffing sandwich 2 bottoms together with mud.Upper annular region water outlet is also for discharging treating pond after the sewage in raising reaction zone 300 and the abundant contact reacts of filler again.In reaction zone 300, there is stirring rake 5, object is to provide flow dynamic, impel sewage to enter in stuffing sandwich 2 from reaction zone 300, this treating pond operation scheme is interval type, so while stopping into water and water outlet, sewage can be got back in reaction zone 300 through stuffing sandwich 2 from annular region, stirring rake 5 intermittently starts, under stirring rake 5 drives, sewage passes through stuffing sandwich 2 in annular region, so repeatedly again from reaction zone 300.In the time that sludge concentration in reaction zone 300 is not enough, start the sludge agitation oar 6 in sludge settling district 400, part mud is stirred with sewage above and mixed, the concentration of mud in raising sewage, without carrying out sludge reflux outside pond again.Unnecessary mud can be discharged from mud relief outlet 13.
As shown in Figure 2, described stuffing sandwich 2 is two semi-cylindrical compositions, an annular stuffing sandwich of two semi-cylindrical compositions, and between two semi-cylindricals, space 21 is left in junction.When inhalant region 100, interior hydraulic pressure is excessive, cannot enter in reaction zone 300 by stuffing sandwich 2 in time, can fast water be entered in reaction zone by gap 21, or the interior water level in reaction zone 300 is too high cannot discharge in time, can enters into exhalant region by gap 21.Gap 21 can also prevent that the sewage in reaction zone 300 from forming closed vortex line under stirring rake 5 effects in addition, can not enter stuffing sandwich 2, and gapped 21 can stop the formation of eddy current.
Described water inlet pipe 11 has two, and symmetrical is distributed in inhalant region 100 and the space 21 of staggering.Many places water intake mode water distribution is even, can improve mixing efficiency, avoids the one-point type problem that the surging force of stuffing sandwich 2 is too concentrated of intaking.
