Embodiment 1

[0032]Such asFigure 1-2As shown, a longitudinal cross-sectional view of an integrated powder provided by the present embodiment, the device is a cylindrical, including a central cylindrical center aerobic region 3, anoxic oxygen surrounding aerobic region 3 / The sedimentation zone 31, the oxygen / precipitation zone 31 includes a hypoxic region 1 with an inlet portion 11, a precipitation region 2 at the upper portion of the hypoxic region 1, further comprising a bottom overflow of the oxygen-deficient zone 1 and the aerobic region 3. The aperture 14, reflows the nitrification fluid in the aerobic region 3 to the reflow system 13 in the oxygen-deficient zone 1; the aerobic region 3 is inclined to the outer axis of the apparatus 55 in the axis of the apparatus through the partition, the oxygen / precipitation region 31. The slider plate 19 is separated from the partition plate 18 and the partitioned spacer 35 in the inner side of the axis in the apparatus, and the slurry plate 19 is ...

Embodiment 2

[0046]The difference between the embodiment and the first embodiment is that the volume ratio of the antoxic region 1 and the aerobic region 3 is 1: 3.5, the surface load of the precipitation zone 2 is 1.3m.3 / M2· H, the device is used to denitrify / nitrate, the volumetric load is 1.2kg BOD5 / M3· The tilt angle in the outer side of the axis of the device is 65 °, and the inclination angle in the inner side of the axis of the apparatus is 65 °.

[0047]The soil flow rate of the discharge stirrer 12 is 0.32 m / s, and the mixed sewage in the device is 0.6 m / s through the bottom overflow 14.

Embodiment 3

[0049]The difference between the present embodiment and the second embodiment and the second embodiment is that the volume ratio of the hypoxic region 1 and the aerobic region 3 is 1: 5, the surface load of the precipitation zone 2 is 2.6m.3 / M2· H, the device is required to be 2.4 kgbod when denitrification / nitrifying biodeprofrination5 / M3· The tilt angle of the D slog 19 to the outer side of the axis of the device is 60 °, and the tilt angle of the partition separator 18 toward the inner side of the apparatus is 55 °.

[0050]The soil flow rate of the flow mixer 12 is 0.4 m / s, and the mixed sewage in the device passes through the bottom overflow hole 14 is 0.8 m / s.

Abstract

The invention provides an integrated powder-loaded enhanced biochemical water treatment device. The device is cylindrical and includes a central cylindrical aerobic zone and an anoxic / precipitation zone surrounding the aerobic zone. The anoxic / precipitation zone includes anoxic The sludge in the sedimentation zone is circulated to the lower part of the aerobic zone through the channel formed by the sliding mud plate and the partition partition, and the sludge in the lower part of the aerobic zone is circulated to the anoxic zone through the reflux system. In the oxygen zone, the sludge completes the synchronous reaction of nitrification and denitrification in the aerobic zone. The integrated powder-loaded enhanced biochemical water treatment device of the present invention combines the powder carrier with the biological filler, and combines the biofilm method with the activated sludge method, which overcomes the low sludge concentration and poor biochemical effect of the traditional biochemical technology. , The disadvantages of large floor area and many single structures. Each reaction unit is closely combined in space, the pool body is built together, the head loss is small, and it has the advantages of high sludge concentration, good treatment effect and small device volume.

Description

Technical field[0001]The present invention belongs to the field of sewage biochemical treatment, and in particular, it is specifically involved in an adultified powder attached to reinforcement of biochemical water treatment apparatus.Background technique[0002]Conventional sewage biochemical treatment has low concentration, limited volumetric load, resulting in limited sewage treatment capacity, resulting in devices (equipment) to reduce the treatment efficiency of sewage, and cannot cope with large load impact, and cover area is large and cannot meet contaminants. The demand of efficient biochemical treatment. At present, my country is strengthening water pollution control due to "Water Ten", and point source pollution control is still the main problem that is currently imposed. Currently, there are many techniques for techniques and devices for point source pollution treatment. However, there are their own disadvantages, chemical treatment cannot effectively nitrogen in sewage, an...
