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 compound preparation of adsorbent method of a kind of thalline/bentonite organic-inorganic.
Background technology
Water treatment agent comprises inorganic coagulant and organic polymer coagulant.Inorganic coagulant is used molysite, aluminium salt, magnesium salts and inorganic polymerization coagulant more.The organic polymer coagulant comprises synthetic organic polymer coagulant and natural organic high-molecular flocculant.Mostly the 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 complicated because of its manufacturing process, and the portioned product price is high, or certain toxicity is arranged, causes secondary pollution etc. because of reason easily; And the industrial wastewater kind is many; The existence of problems such as change of water quality is big, and is hard to manage makes its production and use receive certain restriction and influence.Therefore, force the development of water treatment agent progressively the to be moved towards direction of " producing high-molecular, compoundization, seriation and customizations " is to satisfy 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 provinces such as three provinces in the northeast of China and coastal provinces, east, 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, and the capacity of scientific research lags behind bentonite industry and social development demand.China is again the big country of fermentative Production citric acid, antibiotic and beer simultaneously; Annual citric acid waste residue, antibiotic fermentation waste residue and the brewer's yeast waste residue that will produce the hundreds of thousands ton; Utilize polysaccharide, protein isoreactivity composition development organic-inorganic composite water treatment agent in bentonitic absorption property and the mycothallus; Not only can make full use of the bentonite and fermentation waste thallus resource of China's abundant, enrich organic-inorganic composite water treatment agent kind, turn waste into wealth; Can also reduce cost of water treatment, have great economy and environmental benefit.
Summary of the invention
The object of the present invention is to provide the compound preparation of adsorbent method of a kind of thalline/bentonite organic-inorganic; This method utilization fermentation waste thallus, natural montmorillonite and technical hydrochloric acid or sulfuric acid prepare the organic-inorganic composite adsorbent as water treatment agent through microwave modification, solve complicated process of preparation, cost that existing water treatment agent exists high, have secondary pollution, to the decolorizing effect difference and the difficult removal problem of heavy metal of the little dyestuff of good water solubility or relative molecular mass.
The objective of the invention is to realize through following technical scheme:
The compound preparation of adsorbent method of a kind of thalline/bentonite organic-inorganic, said method comprises following process:
1) prepare raw material: 200 mesh sieves were pulverized in the mycothallus oven dry, and natural montmorillonite was pulverized 200 mesh sieves;
2) preparation of water treatment agent: in mass ratio is that the ratio of 1:10-40 (g/g) is mixed the thalline powder with bentonite; In mass volume ratio is that to add mass fraction be the technical hydrochloric acid of 3%-5% for the ratio of 1:1.2-1.7 (g/mL); Or the sulfuric acid of 3%-7%; Mix 10-15min, leave standstill activation 15-25min, 400-480W microwave modification to crushed after being dried is thalline/bentonite organic-inorganic composite adsorbent product of preparing then.
The described a kind of thalline/compound preparation of adsorbent method of bentonite organic-inorganic, waste thallus and yeast thalline that waste thallus that the black-koji mould filament that its said thalline is the soybean wastewater fermenting and producing, citric acid fermentation produce or antibiotic fermentation produce.
Advantage of the present invention and effect are:
1. the raw material of preparation water treatment agent derive from natural montmorillonite ore deposit and fermentation industry solid waste, and storage is abundant, and is with low cost.Both solved the Solid Waste Pollution problem, outlet was provided, enriched the water treatment agent kind again for it reasonably develops.
2. preparation technology is simple, and is pollution-free, and properties of product are stable, can realize suitability for industrialized production.
3. dosing is few, and the sedimentation time is short, to the reactive dye of pH in the 3-10 scope, acid dyes, basic-dyeable fibre, disperse dyes and and the chromium (VI) of pH in the 1-8 scope higher decolorizing effect and ion remaval rate are preferably all arranged.
The specific embodiment
Below in conjunction with embodiment the present invention is elaborated.
It is mixed even with the 250g bentonite in the 500mL large beaker, to add 10g black-koji mould filament powder, and adding mass fraction again is 3% technical hydrochloric acid 312mL, or 3% the sulfuric acid of 312mL; Stir while adding; Continue to mix 15min, leave standstill activation 15-25min after, place micro-wave oven 480W heat modification and dry; Take out cooling, being ground into powder is mycelium/bentonite organic-inorganic composite water treatment agent product of preparing.Bentonite is city east, Black Hills, a Liaoning natural montmorillonite.
With the printing and dyeing mill of the various concentration of this product treatment homogencous dyes simulated wastewater and Cr commonly used
6+Simulated wastewater has been received treatment effect preferably.Its result is seen 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
