Description
Technical field
The present invention relates to a kind of sewage-treatment plants, specially denitrification treatment tank.
Background technique
The denitrogenation processing that sewage is carried out using filler iron, is widely used, but traditional technique is by filler
It directly or is placed in cage and is placed into reaction tank, filler iron is placed directly in reaction tank, siltation is easy to happen, using putting
It is put into reaction tank in cage, also due to filler bottom is excessively concentrated, sewage and sludge and filler contact surface are also small, instead
It answers inefficient.In addition, traditional anti-digester, from when discharge, a large amount of sludge are also discharged processed waste water therewith, need
Partial sludge in sedimentation basin flow back into reaction tank.
Summary of the invention
In view of the above technical problems, the present invention provides a kind of denitrification pond, improves the contact between sewage, sludge and filler
Face, and avoid the problem that filler deposits in denitrification process, the specific technical proposal is:
Denitrification treatment tank is discharge bay above reaction tank, discharge bay has water outlet including cylindrical reaction tank
Mouthful, there is lid at the top of discharge bay；The annular intake pool of connection evagination, annular intake pool are connected with water inlet below reaction tank, instead
Ying Chi is with installation filling tube in annular intake pool, the tubular that filling tube is circularized by Double-level Reticulated group, fills out among filling tube Double-level Reticulated
Filled with catalytic iron filler；It is mudpan below annular intake pool；Mudpan has mud discharging mouth.
There is the baffle of annular between discharge bay and reaction tank, has circular hole among ring baffle.
Filling tube middle cavity is equipped with inverted horn mouth, bell-mouthed big mouth down, bell-mouthed big mouth and filler
There are sludge through-holes between cylinder cylindrical inner wall；Horn mouth by filling tube internal cavity be divided into top secondary reaction area and lower part just
Order reaction area；Blender and lower blender are separately installed in secondary reaction area and primary reaction zone.
There is swing scraper plate in the discharge bay, swings and be hinged on lid at the top of scraper plate.
There is rotation scraper in the mudpan.
Denitrification treatment tank provided by the invention can sufficiently make sewage and filling tube using circular pattern water inlet
Interior filler contact, and intake below filling tube, to prevent the filler deposition of filling tube lower part.In addition, the cavity of reaction tank
It is divided into the secondary reaction area and the primary reaction zone of lower part on top, extends the reaction time, allows reaction sufficiently to carry out, according to anti-nitre
The reaction principle of chemical industry skill carries out the division of functional areas, and takes stirring or standing as needed, and sludge settling is from horn mouth
Sludge through-hole between big mouth and filling tube cylindrical inner wall returns to primary reaction zone；Mudpan can sink partial sludge
It forms sediment, is used to flow back, do not needed from external returned sludge again.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Specific embodiment
A specific embodiment of the invention is described with reference to the drawings, as shown in Figure 1, denitrification treatment tank, including cylinder
The reaction tank 1 of shape, is discharge bay 2 above reaction tank 1, and discharge bay 2 has water outlet 12, there is lid 7 at the top of discharge bay 2；Reaction tank 1
Lower section connects the annular intake pool 3 of evagination, and annular intake pool 3 is connected with water inlet 11, peace in reaction tank 1 and annular intake pool 3
Barrel 8, the tubular that filling tube 8 is circularized by Double-level Reticulated group are loaded, 8 Double-level Reticulated central filler of filling tube has catalytic iron filler；Ring
It is mudpan 4 below shape intake pool 3；Mudpan 4 has mud discharging mouth 15.
3 volume of annular intake pool and 8 volume ratio optimal value of sizing vat is 1:3.78.
There is the baffle 9 of annular between discharge bay 2 and reaction tank 1, has circular hole among ring baffle 9.
8 middle cavity of filling tube is equipped with inverted horn mouth 13, the big mouth down of horn mouth 13, the big mouth of horn mouth 13
There are sludge through-holes between 8 cylindrical inner wall of filling tube；8 internal cavity of filling tube is divided into the secondary reaction area on top by horn mouth 13
With the primary reaction zone of lower part；Blender 5 and lower blender 6 are separately installed in secondary reaction area and primary reaction zone.
Have in the discharge bay 2 and swing scraper plate 14, it is hinged on the lid 7 to swing 14 top of scraper plate.
There is rotation scraper 10 in the mudpan 4.
The annular intake pool 3 of evagination forms drum organization, accommodates sewage and enters the annular water inlet of progress, annular intake pool 3 is logical
Circular pattern water inlet is crossed, can sufficiently make sewage contact with filler in filling tube 8, and is intake below filling tube 8, i.e.,
Sewage enters from filler lower annular region, using water impact filler, to prevent 8 lower part of filling tube filler because of own wt
Deposition or filler deposit together with sludge and cause filler to fail in 8 bottom of filling tube.
8 internal cavity of filling tube is divided into the secondary reaction area and the primary reaction zone of lower part on top by horn mouth 13.Sewage is first
It enters the primary reaction zone of 8 internal cavity lower part of filling tube, after initial reaction, rises under the action of lower blender 6, enter
The secondary reaction area on top takes stirring or standing in secondary reaction area as needed, and sludge settling is from the big mouth of horn mouth 13
Sludge through-hole between 8 cylindrical inner wall of filling tube returns to primary reaction zone；Horn mouth 13 is inverted, and central through hole is convenient on sewage
It rises, the outside conical surface is convenient for sludge whereabouts.
Mudpan 4 has rotation scraper 10, for assisting spoil disposal, can be used for the dirt in the sewage of supplement top
Mud will have rotation scraper 10 reversely to open, sludge raised into sewage.
Annular baffle 9 between discharge bay 2 and reaction tank 1, communicating passage between reaction tank 1 and discharge bay 2 is reduced, is
Slow down water flow, and for accepting sludge settling, has in discharge bay 2 and swing scraper plate 14, sludge is swept and is led among baffle 9
Road enters reaction tank 1.
