Description
Technical field
The invention belongs to field of solid waste treating technology, in particular to a kind of electrofloatation removes micro- plastics in water body
Method.
Background technique
Micro- plastics are widely present in the environment, for example are distributed in water body, in soil, are easy other in adsorbed water body or soil
Pollutant, including organic pollutant and heavy metal contaminants etc. make enriching pollutants on the surface of micro- plastics, with micro- plastics into
Row migration.In addition, micro- plastics are easy to be absorbed by organism to further result in pollutant in vivo and carry out in the organ of organism
Enrichment, generates biggish bio-toxicity effect.Due to micro- plastics partial size very little, it is more difficult to be separated from environment.
Summary of the invention
In order to solve the above technical problems, the present invention provides a kind of methods that electrofloatation removes micro- plastics in water body:
(1) be added into the water body for being dispersed with micro- plastics chain alkyl amine and the complex compound of copper ion and mix it is abundant,
Wherein, chain alkyl amine is lauryl amine, and the complex compound of chain alkyl amine and copper ion is by mantoquita and chain alkyl amine
Hybrid Heating reacts to obtain,
It first disperses above-mentioned complex compound in ethyl alcohol when addition, then the alcohol dispersion liquid of obtained complex compound is added to water
In body, the mass ratio of complex compound and ethyl alcohol is 1:15~1:30；
(2) electrolysis processing is carried out to mixed water body obtained in step (1),
When electrolysis processing, the anode and cathode being correspondingly arranged is inserted into mixed water body, anode and cathode is all made of graphite
Electrode, the current density for the direct current that electrolysis is applied when handling are 80~200A/m2。
In the present solution, generating bubble in mixed water body using electrolysis measure, hydrogen is specially generated on cathode, in sun
Extremely upper to generate oxygen, these gas bubbles also drive micro- plastics in water body to float while rising, finally will be on water body
Micro- plastics that layer is concentrated collect removing together, realize the separation of micro- plastics and water body, meanwhile, it is anti-that electrode also occurs for electrolytic gas float glass process
It answers, there is the effects of electrochemical oxidation and electrochemical reduction, the organic pollutant in water body can be decomposed simultaneously.According to water body quilt
The principle of electrolysis is it is found that the hydrogen mole generated is bigger, simultaneously because hydrogen density is significantly less than oxygen, therefore electrolysis generates
Hydrogen gas bubbles float go out water body trend it is also more strong, the oxygen generated on anode is significantly greater than to pneumatically supported contribution
Bubble；
And electrolysis processing before, in this programme first by the complex compound of chain alkyl amine and copper ion be well-dispersed in containing
In the water body of micro- plastics, the copper ion which is provided simultaneously with long chain alkyl group in structure and is complexed therewith, therefore have
The property of standby surfactant, enables the complex compound to combine by chain alkyl with micro- plastics, but the complex compound is different from one
As ionic surfactant, general ionic surfactant can ionize decompose in water, and what this programme used
It is complex compound, binding force is stronger between copper ion and chain alkyl, it is possible to copper ion be promoted to be also bonded on micro- plastics.?
On the basis of this, copper ion when due to electrolysis in water body can be to cathodic migration, in the present solution, should be in complex compound
Copper ion has driven micro- plastics to cathodic migration, and hydrogen gas bubbles are exactly generating from cathode and concentrate near cathode, this
Sample makes more micro- plastics float with the effect of hydrogen gas bubbles, improves the removal effect to plastics micro- in water body；
Although copper ion is in sequence compared to H2Hydrogen ion in O preferential will obtain electronics, but in the present solution, on microcosmic
It is the equal of that multiple copper ions drag a micro- plastics to cathode, such copper ion is the equal of what weight bearing moved ahead, can not be too light
It changes places and reaches on cathode, still there is quite a few water to will receive ionization and generate bubble at this time.Therefore in the present solution, cathode
The sequencing that upper hydrogen ion and copper ion obtain electronics should be unable to be it is obvious that in other words, and the generation of bubble and micro- plastics are to yin
The migration of pole should be simultaneously in progress.
