Abstract
The invention discloses a method for preparing a thalli/ bentonite organic and inorganic composite adsorbent, and relates to a method for preparing a water treatment agent. The method comprises the following steps of: 1) preparing raw materials: drying and crushing fungal thalli, sieving with a sieve of 200 meshes, crushing natural bentonite, and sieving with a sieve of 200 meshes; and 2) preparing the water treatment agent: mixing the thalli powder and the bentonite in a mass ratio of 1: (10-40) (g/g), adding 3 to 5 percent by mass of industrial hydrochloric acid or 3 to 7 percent by mass of sulfuric acid in a mass/volume ratio of 1: (1.2-1.7) (g/mL), stirring and mixing for 10 to 15 minutes, standing and activating for 15 to 25 minutes, modifying with microwave of 400 to 480W, drying, crushing, and thus obtaining the thalli/ bentonite organic and inorganic composite adsorbent product. The adsorbent has a good adsorption and decolorization effect and high removal rate on active dyes, acid dyes, alkali dyes, disperse dyes and heavy metals.
Description
Technical field
The present invention relates to a kind of preparation method of water treatment agent, particularly relate to the preparation method of the compound adsorbent of a kind of thalline/bentonite organic-inorganic.
Background technology
Water treatment agent comprises inorganic coagulant and organic polymer coagulant.The multiplex molysite of inorganic coagulant, aluminium salt, magnesium salts and inorganic polymerization coagulant.Organic polymer coagulant comprises synthetic organic polymer coagulant and natural organic high-molecular flocculant.Mostly synthetic organic polymer coagulant is artificial synthetic huge linear molecule, and natural organic high-molecular flocculant has starch derivatives, cellulose derivative, natural plant gum modified product, polysaccharide and protein-based modified product etc.Above-mentioned water treatment agent is because of its manufacturing process complexity, and portioned product price is high, or has certain toxicity, easily causes secondary pollution etc. because of reason, and industrial wastewater kind is many, the existence of the problems such as change of water quality is large, difficult, makes its production and use be subject to certain restriction and impact.Therefore, force the development of water treatment agent progressively the to be moved towards direction of " producing high-molecular, Composite, seriation and customizations ", to meet the needs of different Industrial Wastewater Treatment.China's bentonite resource is abundant, and explored reserves are at the forefront in the world.Mineral products 26 provinces that spread all over the country, more than 20 of large ore deposits, most of mineral deposits concentrate on the provinces such as three provinces in the northeast of China and East Coastal each province, Xinjiang, Sichuan, Gansu, Henan, Guangxi.Bentonite have the title of " omnipotent " clay, is widely used in metallurgy, oil, casting, food, chemical industry, environmental protection and other industrial department.But compared with developed countries, China's bentonite resource application and development level is lower, the capacity of scientific research lags behind bentonite industry and social development demand.China is again the big country that fermentation method is produced citric acid, antibiotic and beer simultaneously, citric acid waste residues, antibiotic fermentation waste residue and the brewer's yeast waste residue of hundreds of thousands ton will be produced every year, utilize polysaccharide, protein isoreactivity composition development organic-inorganic composite water treatment agent in bentonitic absorption property and mycothallus, not only can make full use of bentonite and the fermentation fungi body resource of China's abundant, enrich organic-inorganic composite water treatment agent kind, turn waste into wealth, can also reduce cost of water treatment, there is great economy and environment benefit.
Summary of the invention
The object of the present invention is to provide the preparation method of the compound adsorbent of a kind of thalline/bentonite organic-inorganic, the method utilizes fermentation fungi body, natural montmorillonite and technical hydrochloric acid or sulfuric acid to prepare organic-inorganic composite adsorbent as water treatment agent through microwave modification, solve complicated process of preparation, cost that existing water treatment agent exists high, there is secondary pollution, the poor and difficult removal problem of heavy metal to the decolorizing effect of good water solubility or the little dyestuff of relative molecular mass.
The object of the invention is to be achieved through the following technical solutions:
A preparation method for the compound adsorbent of thalline/bentonite organic-inorganic, described method comprises following process:
1) prepare raw material: mycothallus is dried and pulverized 200 mesh sieves, and natural montmorillonite was pulverized 200 mesh sieves;
2) preparation of water treatment agent: the ratio that is in mass ratio 1:10-40 (g/g) is mixed thalline powder with bentonite, be 1:1.2-1.7(g/mL in mass volume ratio) ratio to add mass fraction be the technical hydrochloric acid of 3%-5%, or the sulfuric acid of 3%-7%, be uniformly mixed 10-15min, leave standstill activation 15-25min, then 400-480W microwave modification to crushed after being dried is thalline/bentonite organic-inorganic composite adsorbent product of preparing.
The preparation method of the described compound adsorbent of a kind of thalline/bentonite organic-inorganic, described in it, thalline is the black-koji mould filament of soybean wastewater fermenting and producing, the waste thallus of citric acid fermentation generation or waste thallus and the yeast thalline that antibiotic fermentation produces.
Advantage of the present invention and effect are:
1. the raw material of preparing water treatment agent derive from natural montmorillonite ore deposit and fermentation industry solid waste, and storage is abundant, with low cost.Both solve the pollution problem of solid waste, for it reasonably develops outlet is provided, enriched again water treatment agent kind.
2. preparation technology is simple, pollution-free, and properties of product are stable, can realize suitability for industrialized production.
3. dosing is few, and the sedimentation time is short, reactive dye to pH within the scope of 3-10, acid dyes, basic-dyeable fibre, disperse dyes and and the chromium (VI) of pH within the scope of 1-8 have higher decolorizing effect and ion remaval rate preferably.
Detailed description of the invention
Below in conjunction with embodiment, the present invention is described in detail.
In 500mL large beaker, add 10g black-koji mould filament powder and 250g bentonite to be mixed evenly, adding mass fraction is 3% technical hydrochloric acid 312mL again, or 3% the sulfuric acid of 312mL, stir while adding, continue to be uniformly mixed 15min, leave standstill after activation 15-25min, be placed in micro-wave oven 480W heat modification dry, take out coolingly, be ground into powder and be mycelium/bentonite organic-inorganic composite water treatment agent product of preparing.Bentonite is Heishan, Liaoning city east natural montmorillonite.
With the printing and dyeing mill of the various concentration of this product treatment conventional homogencous dyes simulated wastewater and Cr
6+simulated wastewater, has received good treatment effect.Its result is in table 1 and table 2,3.
Table 1 sulfuric acid acidation composite type water treating agent is to various decoloring dye waste water effects
Table 2 hcl acidifying composite type water treating agent is to various decoloring dye waste water effects
Table 3 sulfuric acid composite type water treating agent is to Cr
6+removal effect
