Description
Technical field
The present invention relates to industrial wastes processing technique, especially a kind of cutting fluid waste liquid processing method.
Background technique
It is primarily present grease, metal fragment, high organic matter and substance difficult to degrade in cutting waste fluid, these substances are not easy point
Solution, if direct emission can pollute natural environment, it is therefore desirable to pair and learn waste liquid discharge before pretreatment.
Existing processing method is that cutting waste fluid is stood 3-5 days, makes the peroxide not reacted completely in cutting waste fluid
Continue that oxidation reaction occurs, and precipitates the solid impurity in cutting waste fluid.
Existing processing method has the following problems:
1, overlong time is handled, is all generating cutting waste fluid daily in factory, existing processing mode can not keep up with waste liquid generation
Speed；
2, during standing, oxidation reaction persistently occurs, and is also persistently discharged into oxidation reaction with the pernicious gas generated
In air, air pollution is caused.
Summary of the invention
Goal of the invention: solving above-mentioned technical problem, provide one kind can quick processing cutting waste liquid, and can be fully clear from
The method of harmful substance in waste liquid, the present invention propose a kind of cutting fluid waste liquid processing method.
Technical solution: in order to realize the above technical effect, technical solution proposed by the present invention are as follows:
A kind of cutting fluid waste liquid processing method, comprising steps of
(1) metal fragment in cutting waste fluid is removed by Magnetic Isolation；
(2) cutting waste fluid of step (1) after processed is filtered by filter screen, it is miscellaneous filters out solid present in cutting fluid
Will obtains the first treatment fluid；
(3) emulsifier is added in the first filtrate, obtains second processing liquid after removing the oil substance in cutting waste fluid；
(4) medicament is added into second processing liquid, promotes the oxide in second processing liquid that oxidation reaction occurs, obtains at third
Manage liquid；
(5) pH value for adjusting third treatment fluid is neutral value, and coagulated agent is added into neutral third treatment fluid, makes at third
Flocculation reaction occurs for the suspended particulate managed in liquid, forms flocks object, obtains fourth process liquid；
(6) fourth process liquid is filtered, removes the flocks object in fourth process liquid, the clear liquid that obtains that treated.
Further, the whole process of the step (4) carries out under hyperbaric environment.
Further, the Magnetic Isolation processing is is put into more bar magnets in cutting waste fluid, and stands 10 ~ 30min, so
After take out bar magnet, rinse the metal fragment on bar magnet；Finally the waste liquid generated after flushing is filtered and is dried, is obtained
Metal fragment after drying.
Further, the strainer is 40 mesh filter screens.
Further, processing is filtered to fourth process liquid using 25 mesh filter screens in the step (6).
The utility model has the advantages that compared with prior art, present invention has the advantage that
The present invention can fast implement the processing of cutting waste fluid, and can effectively remove grease, metal fragment, high organic matter and difficult to degrade
Substance, so that it is respectively formed the sediment for being easy to filter out, and in the whole process, sufficiently inhibit pernicious gas generation.
Specific embodiment
The present invention will be further explained combined with specific embodiments below.
The present invention proposes a kind of cutting fluid waste liquid processing method, comprising steps of
(1) metal fragment in cutting waste fluid is removed by Magnetic Isolation: being put into more bar magnets in cutting waste fluid, and is stood 10
~ 30min then takes out bar magnet, rinses the metal fragment on bar magnet；Finally the waste liquid generated after flushing is filtered and is dried
Processing, the metal fragment after being dried；
(2) cutting waste fluid of step (1) after processed is filtered by 40 mesh filter screens, is filtered out solid present in cutting fluid
Body magazine obtains the first treatment fluid；
(3) emulsifier is added in the first filtrate, obtains second processing liquid after emulsifying the oil object in cutting waste fluid；
(4) medicament is added into second processing liquid, promotes the oxide in second processing liquid that oxidation reaction occurs, obtains at third
Manage liquid；The whole process of step (4) carries out under hyperbaric environment, to inhibit the spilling of pernicious gas in oxidation process；
(5) pH value for adjusting third treatment fluid is neutral value, and coagulated agent is added into neutral third treatment fluid, makes at third
Flocculation reaction occurs for the suspended particulate managed in liquid, forms flocks object, obtains fourth process liquid；
(6) fourth process liquid is filtered using the strainer of 25 mesh, removes the flocks object in fourth process liquid, is handled
Clear liquid afterwards.
Above-mentioned technical proposal takes out the metal fillings in cutting waste fluid by Magnetic Isolation；It is useless by emulsion reaction emulsification cutting
Oil substance in liquid；Promote the abundant reaction of oxide in cutting waste fluid by the way that catalyst is added, and anti-oxidation occurs
The moment keeps hyperbaric environment during answering, to avoid pernicious gas spilling；By adjusting the pH value of waste liquid, make in oxidation reaction
Heavy metal ion generates precipitating；Make smaller suspended particulate that flocculation reaction occur by coagulated agent, is formed and be easy to the solidifying of filtering
Wadding object；Finally for re-filtering to waste liquid, obtained clear liquid can direct emission.
The above is only a preferred embodiment of the present invention, it should be pointed out that: for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
