Circulating outlet 13 and the second outlet are offered on sedimentation tank 1, is all provided with circulating outlet and the second outlet
Put valve to control.In the present embodiment, outlet pipe 2 is connected with the second outlet, on outlet pipe 2 be provided with valve
To control.
Circulating outlet 13 is connected with the first water inlet 7 by circulating water pipe 11, and is provided with the circulating water pipe 11
For the circulating pump 8 of pressurization.I.e. 11 points of circulating water pipe is two sections, and first paragraph circulating water pipe one end is connected with circulating outlet 13,
The other end is connected with the water inlet of circulating pump 8；Second segment circulating water pipe one end is connected with the outlet of circulating pump 8, the other end with
First water inlet 7 connects.So arrange, it is possible to which the water in sedimentation tank 1 is introduced into water-locator 5.
Also include the first dosing pump 9, the second dosing pump 10, the first dosing pump 9, the second dosing pump 10 pass through pipeline and the
Two-stage nitration circulating water pipe is connected.In the present embodiment, the first dosing pump 9 is used to add copperas solution, the second dosing pump 10 to use
In addition hydrogen peroxide.
Also include intake pump 12, intake pump 12 is connected with water-locator 5 by water inlet pipe 14.I.e. water inlet pipe 14 is by effluent weir 2
Top extends downwardly into fluid bed cylinder 4, on baffle plate 61 opens up inlet opening, and 14 lower end of water inlet pipe is connected on inlet opening.This
Sample is arranged, it is possible to sewage is introduced the mixing chamber 6 of water-locator 5 by water inlet pipe 14.And pass through 14 inside sewage of water inlet pipe
The hydraulic pressure of itself, it is to avoid when intake pump 8 is shut down, the water in cylinder 31 is reverse by 14 upper end of water inlet pipe due to the effect of pressure itself
Into intake pump 12.
So arrange, sewage Jing water inlet pipes 14 first enter water-locator 5, and copperas solution, hydrogen peroxide also Jing pipelines
Water-locator 5 is entered back into into circulating water pipe 11.Sewage, copperas solution, hydrogen peroxide are mixed in the mixing chamber 6 of water-locator 5
After conjunction, enter back into shell and tube fluid bed module 3 and reacted, with the increase of rate of water added, the water level in cylinder 31 is slowly raised, directly
To being overflowed by 31 upper end of cylinder, enter fluidized bed cylinder 4.Water level in fluid bed cylinder 4 is raised also with the increase of the water yield,
Gradually exceed 31 upper end of cylinder, then reach the upper end of fluid bed cylinder 4, sedimentation tank 1 is entered by effluent weir 2 finally.To sedimentation tank 1
Interior water is detected, up to standard then to be discharged by the second outlet, not up to standard, is entered by circulating outlet 13, circulating water pipe 11
Enter mixing chamber 6 and sewage, the copperas solution of water-locator 5, reacted after hydrogen peroxide mixing again, enter back into sedimentation tank 1,
Detection, discharge or recirculation.Whole sewage disposal process is as circulation.
In addition, the filler of packing layer 32 is the granule with Fenton's reaction catalysis activity, and particle diameter is 0.5mm-2.0mm,
Such as quartz sand, brick slag etc..The height of packing layer 32 is 0.5m-2.0m.And the filler of filler lining 33 is that granularity, density are big
In the abrasion resistant particles of packing layer filler, such as bead, stainless steel sand etc., the height of filler lining 33 is 0.1m-0.5m.
The ratio of height to diameter of cylinder 31 is 10:1～40:1, and the diameter of 31 cross section of cylinder is less than or equal to 0.3m.Fluid bed cylinder
The ratio of height to diameter of body 4 is 2.5:1～7:1.
As the ratio of height to diameter of cylinder 31 is larger, and sectional area is less so that filler fluidized state especially bottom in cylinder 31
Portion is preferable near the fluidized state of the filler of water-locator 5, it is easier to realize water distribution uniformity, and further, water distribution uniformity is avoided instead
Device is answered short stream occur, the phenomenon such as channel and dead band makes entirety in cylinder 31 all in preferable fluidized state, make filler and sewage
It is fully contacted, so as to improve sewage treating efficiency.
In sum, in the technical scheme that the application is provided, by the equal water effect of water-locator 5 and filler lining 33, make
In cylinder 31, water distribution is uniform, and the phenomenon such as dead band, channel is substantially reduced.Again due to 31 sections of cylinder in shell and tube fluid bed module 3
Area is less, and ratio of height to diameter is larger, further increases the uniformity of water distribution.And cause cylinder in filler fluidized state especially
Be filler of the bottom near water-locator 5 fluidized state it is preferable, it is easier to realize water distribution uniformity.And water distribution uniformly causes cylinder
In vivo fluidized state is good, and even fluidizing filler particles, medicament, sewage are fully contacted the mass transfer effect that improve reaction system,
Accelerate the efficiency of Fenton's reaction, so as to improve sewage treating efficiency.
The principle and its effect of above-described embodiment only illustrative present invention, it is of the invention not for limiting.It is any ripe
The personage for knowing this technology all can carry out modifications and changes to above-described embodiment under the spirit and the scope without prejudice to the present invention.Cause
This, those of ordinary skill in the art is complete with institute under technological thought without departing from disclosed spirit such as
Into all equivalent modifications or change, should by the present invention claim be covered.
