Description
Technical field
The invention belongs to chemical industry and environmental technology field, relate to a kind of Multifunctional waste water treatment agent, can be used for the process of commonly industrial wastewater physics and chemistry, in addition, also can be used for percolate from garbage filling field Anti-seeping technology.
Background technology
The process of trade effluent and the Anti-seeping technology of garbage loading embeading percolation liquid more and more become one of the hot issue in Environmental Science and Engineering field.In recent years, along with the high speed development of urbanization process, no matter the generation of municipal wastes is that total amount or speedup all increase with exponential form.At present, the process of municipal wastes mainly with landfill and burning electricity generation for mainly to process means.In garbage loading embeading treating processes, selecting and lay efficient, safe sanitary landfill impervious material, is effectively control percolate to the important means of the environmental pollution such as Soil Surrounding, underground water source and measure.And the upgrading and transformation of industry propose more strict requirement for the harmless treatment of sewage.
Wilkinite take montmorillonite as the 2:1 type layered silicate clay mineral of main mineral constituent, there is the ability of Liquidity limit and polar organic molecule, these ions can also be remained on commutative state, can active adsorption process Persistent organic pollutants, in wastewater treatment and pollution law, have broad application prospects.Polyacrylamide is a kind of linear water soluble polymer, it is one of kind be most widely used in water-soluble high-molecular compound, owing to containing a certain amount of polar group in molecular chain, the solids suspended in energy planar water, making builds bridge between particle forms large throw out, accelerates the particle precipitation in suspension.
Modification PAM-sodium bentonite composite water absorbing water-purifying material refers to the feature based on the special laminate structure of wilkinite and polyacrylamide chemical structure, the class energy adsorbed water molecule made, the matrix material of positively charged ion and organic molecule.Both there is the characteristic that inorganic bentonite is excellent, there is again the huge specific surface area of hydrophobic oleophilic oil, and can good treatment effect have been produced in the process of trade effluent physics and chemistry and the application of garbage loading embeading percolation liquid Anti-seeping technology.
Patent CN103708631A describes a kind of sewage-treating agent standby by mixed raw materials such as sepiolite powder, wilkinite, starch xanthate, cross-linked rectorite, polymerize aluminum chloride, chitosans and preparation technology thereof; Patent CN103787473A describes a kind of high stability sewage-treating agent of preparing for raw material with citric acid, sodium carbonate, magnesiumcarbonate, iron trichloride, calcium oxide and polyacrylamide and preparation method.These sewage-treating agent flocculating properties are lower, use the solid waste of rear formation to be difficult to carry out recycling treatment; On the other hand, performance is recycled poor.
Summary of the invention
The object of this invention is to provide a kind of Multifunctional waste liquid treatment agent.
To achieve these goals, the present invention is by the following technical solutions:
A kind of Multifunctional waste liquid treatment agent, is characterized in that being prepared from by following method:
(1) by sodium bentonite calcination 1h under 350 ~ 450 DEG C of conditions;
(2) configuration quality mark is the acrylamide soln of 40 ~ 50%, in mass ratio m
wilkinite: m
acrylamidethe ratio of=1.2 ~ 1:1 adds the wilkinite after calcination, stirs 2h under 40 DEG C of conditions;
(3) get the mixed system that a certain amount of ammonium persulphate adds step (2) gained, the add-on of ammonium persulphate is 3 ~ 5 ‰ of acrylamide quality.;
(4) mixed system obtained by step (3) is warming up to 45 DEG C of reactions;
(5) step (4) reaction automatic heating to 85 DEG C ~ 90 DEG C, and after naturally cooling to 60 DEG C, add linking agent, and temperature is risen to 70 DEG C again, reaction 30min;
(6) dry under the mixture obtained by step (5) being transferred to 30 DEG C of conditions, grind rear mistake 200 mesh sieve, obtain Multifunctional waste liquid treatment agent.
Calcination temperature described in step (1) is preferably 380 DEG C.
Linking agent described in step (5) is N, N '-dimethyl allylidene acid amides; Described N, the add-on of N '-dimethyl allylidene acid amides is 2.6 ~ 6.3 ‰ of acrylamide quality.
The present invention is first by sodium bentonite calcination, add bentonitic bedding void, utilize the cation exchange properties of sodium bentonite, sodium bentonite lamellar spacing is inserted with electropositive ammonium group by acrylamide monomer, propenyl with polymerization activity is placed in environment, as Polymer-supported to the docking point of sodium bentonite, the polyacrylamide be compounded on wilkinite is formed by radical polymerization, special construction through cross-linking modified formation can organic pollutant in active adsorption percolate from garbage filling field or commonly industrial wastewater and inorganic pollutant.
The preparation method of Multifunctional waste liquid treatment agent is further described below:
1. calcination wilkinite.Wilkinite is carried out calcination at a certain temperature, removes a part of middle water and Bound moisture in wilkinite, increase wilkinite bedding void, make it loosen.Temperature will be suitable for, and ensures to remove middle water and Bound moisture, again can not be too high and sintered by wilkinite.Suitable temperature is 350 ~ 450 DEG C, preferably 380 DEG C;
2. monomer intercalation.Wilkinite after calcination is added the acrylamide solution that the wilkinite after calcination is placed in certain mass mark in proportion, is warming up to 40 DEG C, high-speed stirring 2h;
3. in acrylamide solution, the massfraction of acrylamide is 40 ~ 50%, and the sodium bentonite mass ratio after acrylamide and calcination is m
wilkinite: m
acrylamide=1.2 ~ 1:1;
4. aqueous solution polymerization.By 3 ~ 5 ‰ of acrylamide monomer quality, take ammonium persulphate as initiator, add step 2 and obtain in mixed system, be warming up to 45 DEG C and start polyreaction;
5. cross-linking modified.Step 3 polyreaction automatic heating to 85 DEG C-90 DEG C, and after naturally cooling to 60 DEG C, get N by 2.6 ~ 6.3 ‰ of acrylamide massfraction, N '-dimethyl allylidene acid amides, be added in mixed system as linking agent, bath temperature be increased to 70 DEG C, carry out crosslinking reaction;
6. dry grinding.After step 4 starts crosslinking reaction 30min, leave standstill under the system of acquisition being moved to 30 DEG C of conditions and dry, grind rear mistake 200 mesh sieve, obtain percolate from garbage filling field treatment agent.
