Abstract
A kind of pitch sewage sulfur elimination of the present invention, it is characterised in that：For aluminium polychloride and polyaluminum sulfate iron mixture, the sulphion in waste water can be caught the reaction polymerizeing with other pollution suspensions by a series of absorption charge neutrality net in the presence of hydraulic mixing condition, sulfide is promoted to form iron sulfide, and alumen ustum finally is aggregated into other organic pollutions, precipitation forms closely knit sludge under gravity.
Description
Technical field
The present invention relates to a kind of sulfur elimination, specifically, is related to a kind of pitch sewage sulfur elimination.
Background technology
The integrated control of water pollution has caused the most attention of countries in the world, improves the treatment technology of sewage, raising processing
Efficiency, expense and energy consumption are reduced, is still important research contents.It is to consider water resource to solve water pollution most efficient method
Planning, water body purposes, Developing Regional Material-circulation water prevention and cure of pollution.
The dark brown complex mixture that pitch is made up of the hydrocarbon and its non metallic derivatives of different molecular weight,
It is in a liquid state, is a kind of waterproof and dampproof and corrosion-resistant organic cementing material.
Caused sewage is not only muddy smelly in asphalt production process, also many harmful substances, wherein containing a large amount of
SS and COD.
After putting into gas alkali cleaning due to device for asphalt, the sulfide in draining water is constantly raised, and sewage farm is given birth to
Makeup, which is put, to impact, and in order to meet biochemical inflow requirement, the process management of lifting sewage field, specially makes this scheme.
The content of the invention
Instant invention overcomes in the prior art the shortcomings that, there is provided a kind of pitch sewage sulfur elimination, the sulphur in pitch sewage
Compound is efficiently removed, and ensures that secondary air-floatation water outlet is limpid.
In order to solve the above-mentioned technical problem, the present invention is achieved by the following technical solutions：
A kind of pitch sewage sulfur elimination, it is characterised in that：For aluminium polychloride and polyaluminum sulfate iron mixture.
Further, the aluminium polychloride is 12.5 ︰ 1 by quality mixture ratio example with bodied ferric sulfate.
A kind of pitch sewage sulfur elimination, with preparing polymeric aluminium chloride and polyaluminum sulfate iron mixed solution：Fresh water is put into and added
In explosive barrel, start agitator, by quality mixture ratio example be 12.5 ︰ 1 by aluminium polychloride and bodied ferric sulfate, be added to medicine-adding bin
Interior stirring is rear stand-by to being completely dissolved.
A kind of pitch sewage sulfur elimination, start dosing pump and aluminium polychloride and polymeric ferrous sulphate solution are passed through into dosing pipeline
Add, a part adds the sewer line into flotation tank import, and a part is added into one-level flotation tank end, controls medicament
Dosage, there is alumen ustum in observation panel before enabling secondary air-floatation water inlet, and adjusts the content of polyacrylamide, ensures secondary air-floatation
Water outlet is limpid.
Compared with prior art, the beneficial effects of the invention are as follows：
A kind of pitch sewage sulfur elimination of the present invention, it is characterised in that：Mixed for aluminium polychloride and bodied ferric sulfate
Thing, in the presence of hydraulic mixing condition can by the sulphion in waste water with it is other pollution suspensions by it is a series of absorption-
Charge neutrality-net is caught-reaction polymerizeing, promote sulfide to form iron sulfide, and finally aggregate into alumen ustum with other organic pollutions,
Precipitation forms closely knit sludge under gravity.
Embodiment
The preferred embodiments of the present invention are illustrated below, it will be appreciated that preferred embodiment described herein is only used
In the description and interpretation present invention, it is not intended to limit the present invention.
A kind of pitch sewage sulfur elimination, it is characterised in that：For aluminium polychloride and polyaluminum sulfate iron mixture.
Application method is as follows：
1. preparing polymeric aluminium chloride and polyaluminum sulfate iron mixed solution：Fresh water is put at 1 meter of medicine-adding bin, starts stirring
Device, aluminium polychloride and bodied ferric sulfate need to be added into 2kg polymerised sulphurs by quality mixture ratio example for the packet aggregation aluminium chloride of 12.5 ︰ 1,1
Sour iron, is added in medicine-adding bin that stirring is rear stand-by to being completely dissolved, and the emphasis of present patent application is aluminium polychloride and polymerised sulphur
Sour iron is 12.5 ︰ 1 by quality mixture ratio example, and the ratio makes sewage obtain best sulfur limitation effect, and secondary air-floatation water outlet is limpid.
2. starting dosing pump to add confection solution by dosing pipeline, a part is added into flotation tank import
Sewer line, a part are added into one-level flotation tank end, control added amount of chemical, enable observation panel before secondary air-floatation water inlet
There is alumen ustum, and adjust the content of polyacrylamide, after adding vulcanizing agent, small group is formed in water, settleability is poor, polyacrylamide
The addition of amine, accelerate its sedimentation, ensure that secondary air-floatation water outlet is limpid.
Sulfide is reduced using bodied ferric sulfate
Ferrous sulfate has very strong oxidation-reduction quality, very high to the clearance of sulfide.Ferrous sulfate or polymerised sulphur
Ferrous ion (Fe2 caused by hydrolysis after sour iron (bodied ferric sulfate sulphide removal effect is very good) is added in waste water+)
Can be with sulphion (S2-) react generation iron sulfide (FeS) precipitate into sludge.On the other hand, ferrous sulfate is put into waste water
In after, its hydrolyze caused by complex compound, can be by the sulphion in waste water and other pollutions in the presence of hydraulic mixing condition
Suspension promotes sulfide to form iron sulfide by a series of absorption-charge neutrality-net is caught-reaction polymerizeing, and finally and its
Its organic pollution aggregates into alumen ustum, and precipitation forms closely knit sludge under gravity.
Finally it should be noted that：The preferred embodiments of the present invention are these are only, are not intended to limit the invention, although
The present invention is described in detail with reference to embodiment, for those skilled in the art, it still can be to foregoing
Technical scheme described in each embodiment is modified, or to which part technical characteristic carry out equivalent substitution, but it is all
Within the spirit and principles in the present invention, any modification, equivalent substitution and improvements made etc., the protection of the present invention should be included in
Within the scope of.
