Technical field

The invention belongs to waste water treatment fields, and in particular to a kind of magnetism luffa charcoal and preparation method thereof and answer With.

Background technique

With the development of industry, the discharge of various industrial wastewaters brings serious pollution to water environment.China is one existing Generation weaving big country, the dyeing waste water generated in process of textile production is always one of important pollution sources of industrial wastewater.Printing and dyeing Containing the organic matter of large amount of complex in waste water, so that not only coloration is high for dyeing waste water, and be difficult to be degraded, it is unprocessed or Qualified discharge not only does not cause seriously to pollute to water body, also results in serious harm to people's lives health.It thus need to be to print Dye waste water is effectively treated.

The major technique of dyeing waste water has absorption method, coagulant sedimentation, catalysis method, membrane separation process, electrochemical process etc. at present, The each have their own merits and demerits of these technologies, being applied in sewage disposal process complicated and changeable also has certain limitation, portion Point method also because cost is too high can not large-scale application.The relatively inexpensive practical method of one kind is absorption method in these methods, It is easy to operate, economical, is suitble to practical application.Active carbon in adsorbent material can adsorb the substance in various wastewater, Treatment effect is preferable.Biological carbon materials adsorption capacity emerging in recent years is strong, has flourishing gap structure and higher compares table Area.Biological carbon materials are from a wealth of sources, various structures, so that it has broader practice prospect in wastewater treatment.

Sponge gourd is plant common in a kind of life, and the luffa of cellulose very abundant is formed after mature.Luffa master It to be made of cellulose (82.4%), lignin (11.2%), ash content (0.4%) etc., there is unique porosity physical structure With excellent mechanical strength, have many advantages, such as that toughness is strong, acid-proof alkaline is good.Luffa is a kind of renewable resource, has valence The features such as honest and clean, degradable, prepares charcoal using luffa, and because its own pore structure is abundant, manufactured charcoal is had excellent performance. There is certain advantage compared with other biological charcoal, be applied to wastewater treatment with better performance.

The single charcoal adsorbent material made of loofah fiber element still has shortcoming, such as patent CN104561636A Magnetic luffa metal prepared by described a kind of porous block magnetic metal based on luffa preparation and preparation method thereof Adsorbent need to be in 450~900 DEG C of high-temperature calcinations, and reducing metal oxide, preparation method need to consume in nitrogen/hydrogen atmosphere Can be higher, preparation process is complicated.The system of the modified porous magnetic luffa complex microsphere of one kind described in patent CN107456954A In Preparation Method, chemical reagent type needed for prepared by complex microsphere is more, and cumbersome, treatment process difficulty is larger.Patent Described in CN105642245A it is a kind of magnetism egg white/luffa adsorbent material preparation method in need with mulberry leaf, loguat leaf and Ginkgo leaf prepares leaf leaching liquid, and required raw material should not be obtained largely, and the cost is relatively high for egg white.

Summary of the invention

In view of the above problems, it proposes on the present invention overcomes the above problem or at least be partially solved in order to provide one kind State the magnetic luffa charcoal and its preparation method and application of problem.

The embodiment of the present invention provides a kind of preparation method of magnetic luffa charcoal, comprising:

Obtain luffa；

The luffa is placed in ferric chloride solution and is impregnated, filter and is dried；

By the luffa after the drying by high temperature load method, magnetic luffa charcoal is obtained.

Further, the luffa that obtains includes: to choose mature dry chalina, crushes, is sieved after deseeding, obtains Luffa.

Further, described to cross grit number≤80 mesh.

Further, the ferric chloride solution concentration is 0.1-30g/L.

Further, the soaking time is 10-12 hours.

Further, the luffa by after the drying obtains magnetic luffa charcoal by high temperature load method Include:

By the luffa after the drying in 300-500 DEG C of temperature lower calcination 60-80min, natural cooling obtains magnetic silk Melon network charcoal.

Based on the same inventive concept, the embodiment of the present invention also provides a kind of preparation method by magnetic luffa charcoal The magnetic luffa charcoal being prepared.
