Description
Technical field
The present invention relates to water purification agents, and in particular to a kind of composite water purifying agent.
Background technique
The purification of drinking water has been the project that the whole world is paid close attention to jointly now.Currently, net because chemistry is used for a long time
Aqua, and make to remain chemical substance in water and human body may be damaged, because environment is asked caused by the residue after water purification
Topic also can not be ignored.
Heavy metal has stronger sustainable toxicity in water body, cannot be biodegradable, can enter life by food chain
It is accumulated in object, thus heavy metal pollution receives much attention.Cadmium is the strongest heavy metal of toxicity as human body non-essential element
One of element, the main source of cadmium pollution are industrial wastewaters, such as mining, plating, alloy manufacture, battery production.Traditional weight
Metallic wastewater processing method mainly includes ion-exchange, membrane filter method, chemical precipitation method, electrochemical process etc., but these methods
The disadvantages of there are processing cost height, low efficiency or be easy to causeing secondary pollution.Although absorption method is a kind of high-quality and efficient processing
Method, but the cost of the conventional adsorbents such as active carbon and regeneration expense are all more expensive.Therefore, developing good water purification agent becomes
The hot spot of Recent study.
Summary of the invention
Technical problems based on background technology, the invention proposes a kind of composite water purifying agents.The present invention can improve
Water quality has excellent removal effect to Heavy Metals in Waters ion.
A kind of composite water purifying agent proposed by the present invention, raw material include: by weight 20-45 parts of attapulgite, modification it is small
20-30 parts of wheat husk, 4-8 parts of aluminum sulfate, 6-9 parts of chitosan, 5-8 parts of sodium carbonate, 2-2.5 parts of paragonite, 6-9 parts of calcium hypochlorite,
12-18 parts of camphor leaf extract.
Preferably, the modified wheat shell the preparation method comprises the following steps: wheat shell is placed in peroxysuccinic acid solution, acid
Change, filtration, dry filter residue obtains pretreatment wheat shell；Pretreatment wheat shell, peroxysuccinic acid, boric acid are taken, distilled water is added
In, washing filters, dry filter residue obtains modified wheat shell to neutrality after heating reflux reaction.
Preferably, the mass volume ratio (g/ml) of the wheat shell and peroxysuccinic acid solution is 1:20-30.
Preferably, the mass fraction of the peroxysuccinic acid solution is 20-28wt%.
Preferably, the souring temperature is 50-60 DEG C, acidificatoin time 1.5-2h.
Preferably, the time of the back flow reaction is 3-3.5h.
Preferably, it is described pretreatment wheat shell, peroxysuccinic acid, boric acid mass ratio be 15-20:25-36:3-7.
Preferably, the mass volume ratio (g/ml) of the pretreatment wheat shell and distilled water is 1:15-25.
Preferably, in the operation of the dry filter residue, temperature is 85-95 DEG C, vacuum degree 0.08-0.15MPa.
Each raw material is uniformly mixed granulation in the preparation by the present invention.
Raw material of the invention includes attapulgite, modified wheat shell, aluminum sulfate, chitosan, sodium carbonate, paragonite, secondary chlorine
Sour calcium, camphor leaf extract, reasonably combined, having improves water quality, the effect of efficient absorption degradation Heavy Metals in Waters ion.This
Invention is modified wheat shell, and wheat shell is placed in peroxysuccinic acid solution, is acidified, filtration, and dry filter residue obtains pre-
Handle wheat shell；Take pretreatment wheat shell, peroxysuccinic acid, boric acid, be added distilled water in, washed after heating reflux reaction to
Neutrality, filtration, dry filter residue obtain modified wheat shell；Since wheat shell is rich in lignin, cellulose and hemicellulose, have
Porous structure, surface have good adsorption capacity with the functional groups such as hydroxyl, carboxyl, to heavy metal, by with peroxidating fourth
Diacid, boric acid carry out back flow reaction, and esterification occurs for the hydroxyl on one end and wheat shell of peroxysuccinic acid, are allowed to connect
Upper carboxyl, considerably increases the carboxyl on wheat shell surface, and then significantly improves modified wheat shell to the adsorption capacity of heavy metal, this
Outside, acidizing pretreatment is carried out to wheat shell, the peroxysuccinic acid with strong oxidizing property can generate the surface of wheat shell strong
Corrosiveness, so that smooth wheat wall surface is become coarse, and the degree of polymerization of lignocellulosic can be reduced, simultaneous oxidation table
Face group, further increases exposed suction attachment position and the activation useful group of wheat shell, and increases the gap inside sawdust, increases
Add the contact area with water；After modified wheat shell and attapulgite, chitosan synergistic effect, significantly improve of the invention net
Water effect, to the removal rate of heavy metal 99% or more.
