Abstract
The invention discloses the phosphorus removing method of the phosphorus-containing wastewater produced in a kind of anodic oxidation surface with chemical polishing technology.The method includes first configuring copperas solution；Take the phosphorus-containing wastewater of chemical polishing, use alkali liquor regulation wastewater pH to alkalescence, be subsequently adding a certain amount of copperas solution, be sufficiently stirred for reaction；Question response adds PAM after terminating and carries out flocculation sediment；Filtrate discharge after solid-liquid separation；Filtering residue phosphorus content is higher, can be as agricultural sludge Fertilizer application.The method technique of the present invention is simple, waste water dis posal low cost, and sewage sludge output is low.To low-concentration phosphorus-containing wastewater (TP≤1000ppm) clearance up to more than 95%, to high-concentration phosphorus-containing wastewater (10000 ~ 50000mg/L) clearance up to 97%；Can be widely applied in the process of anodic oxidation industry-specific optical polishing waste water.
Description
Technical field
The present invention relates to field of waste water treatment, be specifically related in a kind of anodic oxidation surface with chemical polishing technology the phosphorous useless of generation
The phosphorus removing method of water.
Background technology
In order to overcome the defect of the aspects such as aluminum alloy surface hardness, mar proof, expand range of application, extend and use the longevity
Life, process for treating surface become aluminium alloy use in an indispensable ring, and anodizing technology be the most most widely used and
Most successful.The waste water that anodic oxidation process chemistry polishing section produces is higher because of acidity and phosphorus content, there is improvement all the time
The problem of difficulty.Surface with chemical polishing technology uses " three acid " (phosphoric acid, sulphuric acid, nitric acid) because of more, and wherein mostly more than 70% be phosphoric acid, because of
And it is higher to produce phosphorus in waste water content, general washing water about 200 ~ 1000ppm, some recycle-water washing trough concentration is the most up to ten thousand.
At present processing method mostly is calcium salt precipitation method, carries out flocculation sediment by adding lime cream, but because of a large amount of sulfate radicals etc. in waste water
Also can combine with calcium salt and form precipitate, therefore the produced sludge quantity of this method is very big, and anodized waste water sludge output is up to 5%.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides in a kind of anodic oxidation surface with chemical polishing technology produce contain
The phosphorus removing method of phosphorus waste water.
Technical scheme is as follows:
A kind of phosphorus removing method of the phosphorus-containing wastewater produced in anodic oxidation surface with chemical polishing technology, it is characterised in that
Comprise the following steps:
(1) configuration concentration 25%-35% copperas solution；
(2) take the phosphorus-containing wastewater of chemical polishing, first measure TP concentration in waste water；
(3) in phosphorus-containing wastewater, alkali liquor is added, the pH to 8.5-9.5 of regulation waste water；
(4) regulate in the waste water of pH value to step (3) than the ratio for 3.2-3.5 in Fe/P and add a certain amount of ferrous sulfate
Solution, stirring reaction 55-65min, then adding the polyacrylamide PAM flocculation sediment of waste water gross weight 1 ‰；(5) the most heavy
Carrying out solid-liquid separation behind shallow lake, filtrate is directly discharged, and filtering residue reclaims as agricultural sludge Fertilizer application.
The phosphorus removing method of the phosphorus-containing wastewater produced in described a kind of anodic oxidation surface with chemical polishing technology, it is characterised in that:
Alkali liquor described in step (3) be concentration be the sodium hydroxide solution of 30%.
When the phosphorus concentration in phosphorus-containing wastewater is the highest, because sediment volume is relatively big, need to first add water or other waste water mixes
Process again after closing dilution, otherwise affect treatment effect, about thinner ratio 1:6.
Beneficial effect
The method technique of the present invention is simple, waste water dis posal low cost, and sewage sludge output is low.To low-concentration phosphorus-containing wastewater (TP≤
1000ppm) clearance is up to more than 95%, to high-concentration phosphorus-containing wastewater (10000 ~ 50000mg/L) clearance up to 97%；Can be wide
In the general process being applied to anodic oxidation industry-specific optical polishing waste water.
Detailed description of the invention
Embodiment 1:
Taking anodic oxidation chemical polishing washing water 100ml, phosphorus concentration 264mg/L, adding 30% liquid caustic soda regulation pH value of waste water is about 9；
Take 30g ferrous sulfate to be dissolved in 70ml water, prepare 30% strength solution, stand-by after stirring and dissolving；By Fe/P ratio 3.2, add ferrous molten
Liquid 1.4ml, stirring reaction 60min, after add 1 ‰ PAM1ml flocculation sediments, filter and survey filtrate TP concentration 12mg/L, clearance
95.5%。
Embodiment 2:
Take anodic oxidation chemical polishing accumulator tank waste water 100ml, phosphorus concentration 52800mg/L, add water 650ml(or other alkalescence useless
Water) add 30% alkali liquor regulation wastewater pH about 9；Take 300g ferrous sulfate to be dissolved in 700ml water, stand-by after stirring and dissolving；By Fe/P
Add ferrous iron solution 300ml than 3.5, stirring reaction 60min, after add 1 ‰ PAM5ml flocculation sediments, survey filtrate TP concentration after filtration
1244mg/L, tp removal rate 97.6%；Producing mud butt amount 5g, equivalent 75% mud amount 20g, produce mud ratio 2%, mud amount is compared 5% and is substantially dropped
Low.
Note: to high-concentration phosphorus-containing wastewater, because sediment volume is relatively big, need to first add water or other waste water mixed dilutings enter again
Row processes, and otherwise affects treatment effect, about thinner ratio 1:6.
