Abstract
The invention discloses an adsorption and decoloration method of printing and dyeing wastewater by using power plant straw ash. In the method, the contact treatment is carried on the printing and dyeing wastewater by using the power plant straw ash so that the power plant straw ash adsorbs dye compounds in the printing and dyeing wastewater to ensure that the printing and dyeing wastewater obtains a decoloration effect. The invention has the advantages that the cost is low and the pressure caused by the stacking of power plant straw ash is released, is a typical recycling economy mode and has larger economic and environment-friendly meanings.
Description
Technical field
The present invention relates to biological environmental production material field, specifically is the absorption decoloring method of a kind of power plant straw ash to dyeing waste water.
Background technology
In the last thirty years, water body organism pollutes the new focus that becomes countries in the world scientific circles and government's concern.Though organic pollutant great majority content in water is very little, and is very big to the mankind's harm.Studies show that of ecotoxicology, some utmost point of this pollutant embarrasses biological decomposition, chemical oxidation and absorption also there is hindrance function, in acute and chronic toxicity test, often do not show toxic effect, but can be hydrobiont, migration in farm crop and the other biological body, conversion and enrichment, and have and three cause (carcinogenic, teratogenesis, mutagenesis) effect, under long period, low dosage condition, often can cause serious or even irreversible influence to ecotope and HUMAN HEALTH.
Dyeing waste water is that processing cotton, fiber crops, man-made fiber and blending product thereof are the waste water that main printing and dyeing mill discharges.The dyeing waste water water yield is bigger, 100～200 tons of 1 ton of textiles water consumptions of every printing and dyeing processing, and wherein 80～90% become waste water.One of notable feature of dyeing waste water is to have higher colourity.Through after the biochemical treatment, effluent color dilution decreases, but still has darker color and luster, is difficult to reach emission standard.Therefore, decolouring is an important step in the treatment of dyeing wastewater.The dye species of whole world use at present reaches tens thousand of kinds, and wherein reactive dyestuffs are just adopted more and more widely owing to its lovely luster, chromatogram are complete.But because the physicochemical property of reactive dyestuffs makes it become one of difficult dyestuff of removing in the dyeing waste water.
Micro-nano material generally is meant the material of size in 1nm～10 μ m, and peculiar performances such as the small-size effect of micro-nano material, surface effects and quantum effect provide important basic substance.In recent years, micro-nano material gets most of the attention in the research of aspects such as catalysis and absorption, nano material loading, one of wherein uses to use in decolorizing printing and dyeing waste water exactly.The nano material that is used for decolorizing printing and dyeing waste water commonly used has natural clay, nano-metal-oxide etc., and these materials all have good decolorizing effect, but all exists cost of manufacture height or limited, the non-renewable problem of reserves.
Because the transition of fossil energies such as coal, oil exploitation utilizes, these Nonrenewable resources are fewer and feweri even approaching exhausted.At this problem, biomass energy is made a kind of emerging alleviation approach and is suggested, develops and utilize in recent years, and concrete grammar has a variety of, and one of them is, plantation big area energy-source plant is then as the dyestuff combustion power generation of power plant.This has alleviated the crisis of fossil energy on the one hand to a certain extent; but meanwhile brought the another one problem; that is exactly annual a large amount of stalk ash that produces; still there is not the method for effectively utilizing at present; pile up pressure, government pressure etc. thereby cause; expend great amount of manpower and material resources and financial resources, if mismanagement causes air-borne dust to pollute easily.Because the stalk ash contains more rich amorphous silicon (with SiO
2Count about 5-20%), studies show that have two kinds of holes in the stalk ash: a kind of is the honeycomb hole of micro-meter scale (～10 μ m), is staggered to form by the stalk fibre plate, relevant with the stalk weave construction and irrelevant with burning process; Another kind is the SiO of nanoscale
2The particle mesopore is by SiO
2The non-tight gathering of gel particles forms, and is relevant with burning process, and it is contrast table area and chemically reactive generation great influence then.SiO
2Micro-nano porous structure has determined that the stalk ash has higher adsorption activity.
Summary of the invention
The invention provides the absorption decoloring method of a kind of power plant straw ash to dyeing waste water, it is low to have a cost, alleviates the advantage that power plant straw ash is piled up the pressure that causes, and is a kind of typical recycling economy mode, has bigger economic implications and environment protection significance.
Technical scheme of the present invention is:
Power plant straw ash is characterized in that the absorption decoloring method of dyeing waste water: contact processing with power plant straw ash with dyeing waste water, make the dye composition in the power plant straw ash absorption dyeing waste water, to the effect that obtains decolouring that makes dyeing waste water.
Described power plant straw ash is to the absorption decoloring method of dyeing waste water, it is characterized in that: described contact handle be meant with dyeing waste water with 1-10 rice/minute velocity flow cross the power plant straw ash filter post that diameter is 0.01-1m, adjust the filter column length and reach different decolorizing effects.
Described power plant straw ash is to the absorption decoloring method of dyeing waste water, it is characterized in that: described contact processing is meant to be added power plant straw ash in the dyeing waste water to according to the 0.01-5g/L mass ratio, stirred 5-20 minute, static till reaching decolorizing effect and meeting the requirements, will precipitate residue then and remove by filter.
Described power plant straw ash is to the absorption decoloring method of dyeing waste water, it is characterized in that: described contact processing is meant to be added power plant straw ash in the dyeing waste water to according to the 0.01-5g/L mass ratio, stirred 5-20 minute with 60-120 rev/min of speed, static till reaching decolorizing effect and meeting the requirements, add the 0.005-0.1g/L flocculation agent then and make solid matter all flocculation and precipitation, supernatant liquor is shifted out get final product at last.
Described power plant straw ash is characterized in that the absorption decoloring method of dyeing waste water: described flocculation agent is selected polyacrylamide, chitosan, polymerize aluminum chloride or poly-ferric chloride for use.
Because the stalk ash contains more rich amorphous silicon (with SiO
2Count about 5-20%), wherein have two kinds of holes: a kind of is the honeycomb hole of micro-meter scale (10 μ m); Another kind is the SiO of nanoscale
2The particle mesopore is by SiO
2The non-tight gathering of gel particles forms.SiO
2Micro-nano porous structure has determined that the stalk ash has higher adsorption activity, thereby dye composition can be adsorbed in its micro-nano porous structure, reaches the effect of decolouring.
Beneficial effect of the present invention is:
1, reduce the sorbing material cost to greatest extent: power plant straw ash is a remaining residue after power plant's burning energy-source plant, belongs to industrial residue for power plant, does not have utility value, thereby does not have cost;
2, alleviate accumulation pressure: along with the expansion of biomass power generation, power plant straw ash increases year by year, not only takies the big area place, and expends a large amount of human and material resources and financial resources, thereby the development and use power plant straw ash can effectively delay these pressure;
3, turn waste into wealth, the treatment of wastes with processes of wastes against one another: power plant straw ash adsorption bleaching dyeing waste water, belong to waste become and have the industry and the environment-friendly function material of commercial value, be a kind ofly typically turn waste into wealth, the way of the treatment of wastes with processes of wastes against one another.
