Description
Technical field
The present invention relates to technical field of waste water processing, more specifically, it relates to a kind for the treatment of process of waste emulsified mixture.
Background technique
Emulsion is the semi-synthetic processing liquid product containing mineral oil, is suitable for extensive aluminium casting production operation.
However, emulsion has certain service life, once being more than the service life, emulsion is easy to cause pH occur
Value decline, water-oil separating, generation sediment or greasy filth, color become taupe by milky, generate phenomena such as putrefactive odor, show
Emulsion at this time is corrupt, can not carry out again using.
However, due to containing mineral oil and other non-solubility organic matters, dissolved organic matter in waste emulsified mixture, if directly
Capable discharge is tapped into, serious environmental problem certainly will be will cause, be unfavorable for sustainable development.
However, existing when handling waste emulsified mixture, since oily substance therein is more and hindering has other
The removal rate of machine object is had a greatly reduced quality, and therefore, a kind of pair of oily substance has the processing work of the waste emulsified mixture of preferable removal effect
Skill has more vast market prospect for waste emulsified mixture field.
Summary of the invention
In view of the deficienciess of the prior art, the first purpose of this invention is to provide a kind of processing work of waste emulsified mixture
Skill effectively removes the oil substances in waste emulsified mixture, and reduces it and cause shadow to other organic matter degradations, removal
Loud advantage.
To realize above-mentioned first purpose, the present invention provides the following technical scheme that
A kind for the treatment of process of waste emulsified mixture, includes the following steps:
Step 1 is added lye into the waste emulsified mixture of collection, is sufficiently mixed, and control pH value is 9.0-10.0；Add first
Handle intermixture, be sufficiently mixed, carry out first time air bearing reaction treatment, the processing time is 5.5-6h, removal wherein occur the
One non-solubility organic matter obtains waste water after single treatment；
Step 2 is added second processing intermixture, is sufficiently mixed in waste water after the single treatment obtained into step 1, carry out the
Secondary air bearing reaction treatment, processing time are 4-5h, remove the second non-solubility organic matter wherein occurred, obtain secondary treatment
Waste water afterwards；
Waste water after the secondary treatment obtained in step 2 is hydrolyzed at the biochemical degradation of acidification pool and aerobic tank step 3
Reason, filtering obtain processed waste water three times；
Step 4, in the processed waste water three times obtained into step 3 plus acid for adjusting pH value is 2.5-3.0；It adds at third
Manage intermixture, be sufficiently mixed, then plus alkali adjust pH value be 9.0-10.0, then plus fourth process intermixture, be sufficiently mixed, obtain four
Secondary processed waste water；
Step 5, is added that concentration is 10%, additive amount is 75-80L/h's in four processed waste waters obtained into step 4
Sodium hypochlorite is sufficiently mixed, and reacts 2.5-3.5h, obtains qualified discharge clear water；

As shown in Table 11, in test sample 1-17, after the operation of step 1, it can remove more oily substance, and control sample
Oily removal rate is lower in 1-5.
In test sample 6-8, in step 1, polyvinyl alcohol is added before lye is added, is dispersed in water, favorably
In floating on the oily substance in water on liquid level, there is some superiority to removal oily substance.
In test sample 9-11, since polyvinyl alcohol is being added and then oil-absorbing resin is added, be further conducive to oils
Substance is removed.In test sample 9-15, the composition of monomer used in oil-absorbing resin is prepared, is inhaled than being prepared in test sample 16-17
The combination of monomer used in oleoresin is more reasonable, and therefore, test sample 16-17 is easier to than the oily substance in test sample 9-15
It is adsorbed and removes.
And in control sample 1, disposably add medicament, it is difficult to which preferable removal effect is generated to the oily substance in waste emulsified mixture
Fruit.In control sample 2-5, although the processing step taken is identical as in embodiment 1-17, taken in identical step
The medicament of addition is different, is easy to cause the effect of removal oily substance poor.
Therefore, reasonable arrangement operating procedure, and reasonable medicament is added in operation, it helps to improve to useless cream
Change the removal effect of oily substance in liquid.
Oily removal rate (%) in 12 test sample 1 ' -19 ' of table, control sample 1 ' -5 '
| Test specimen | After step 2 (%) | Test specimen | After step 2 (%) |
| Test sample 1 ' | 82.7 | Test sample 13 ' | 85.6 |

| Test sample 12 ' | 85.2 | Control sample 5 ' | 47.2 |
As shown in Table 12, after step 2, the oily removal rate of test sample 1 ' -19 ' has a bigger promotion, and control sample
Although oily removal rate in 2 ' -5 ' improves, but ascensional range is less than the rising of the oily removal rate of test sample 1 ' -19 '
Amplitude.For the control sample 2 ' -5 ' that compares, the amplitude of the oily removal rate of control sample 1 ' is smaller, and reason is: although in comparative example
Step (8) in 1 although in take filtering measure, it is poor to the filter effect of oily substance.
