Description

Steel mill's waste residue composition for filtration treatment sewage and preparation method thereof
Technical field
The present invention relates to reusing for steel mill's waste residue, and more specifically it is steel mill's waste residue for filtration treatment sewage Composition.The invention further relates to the method for preparing steel mill's waste residue composition for filtration treatment sewage.
Background technology
Steel mill's waste residue is caused waste residue after steel mill's production, and annual steel mill of China has substantial amounts of waste residue to produce, these waste residues A part is used as cement additire, and the slag in steel mill can improve the improvement coagulation of cement as the additive in cement Density, impermeability, the corrosion resistance of soil, and the later strength of concrete is increased substantially, so as to significantly improve the resistance to of concrete Long property, but still there are a large amount of waste residues to be stacked or be taken as garbage disposal, waste of resource and pollution environment.
Preconditioning technique is also referred to as using pre-treatment in existing sewage disposal, it is conventional have grid or grid, regulating reservoir, Setting pot, preliminary sedimentation tank etc., these processing modes will typically pass through several levels in processing procedure could complete to pre-process, and operation is multiple Miscellaneous, treatment effect is unsatisfactory, only filters the suspension of bulky grain, and can not remove the smell of sewage.
Quick lime, main component are calcium oxide, and usual preparation method is by the natural rock that main component is calcium carbonate, in high temperature Lower calcining, you can decompose generation carbon dioxide and calcium oxide (chemical formula：CaO, i.e. quick lime, also known as marble)；Quick lime is The conventional drier of vapor is removed using chemical absorption method, is also used for the de- of steel, agricultural chemicals, medicine, drier, process hides and alcohol Water etc.；Especially suitable for the local and special products such as dilated food, mushroom, agaric, and instrument, medicine, dress ornament, electronics telecommunication, skin The product of the industries such as leather, weaving；Filler can be made, such as：Filler as epoxy adhesive；As analytical reagent, gas It is used as carbon dioxide, sulphur dioxide absorbent, spectrum analysis reagent during analysis, high purity reagent is used for outer in semiconductor production Prolong, diffusing procedure, the drying of laboratory ammonia and alcohols dehydration etc.；As raw material, calcium carbide, soda ash, bleaching powder etc. can be manufactured, For process hides, purification of waste water, calcium hydroxide and various calcium compounds；It can be used as construction material, metallurgical fluxing agent, cement rapid hardening Agent, the fluxing agent of fluorescent material；It can be used as vegetable oil decoloration agent, pharmaceutical carrier, soil conditioner and calcareous fertilisers；It can be additionally used in fire proofed wood Material, drier；Agricultural machinery 1, No. 2 glue and underwater epoxy adhesive can be prepared, also serves as the reactant with 2402 resin pre-reactions；Can It is quenched for acid waste water processing and sludge；Boiler Shut-down Protection agent is also acted as, using the wettability power of lime, makes boiler water The metal surface of vapour system keeps drying, prevents from corroding, suitable for low pressure, pressure, the Long-time Shut-down of low capacity dum boiler protect Shield.
Activated carbon, it is black powder or bulk, graininess, cellular amorphous carbon, the crystal for also having arranged regular Carbon；In activated carbon in addition to carbon, also comprising two class admixtures：One kind is chemically combined element, mainly oxygen and hydrogen, these Element is due to not carbonize and remained in charcoal completely, or in activation process, external is non-CarbonWith activated carbon surface Chemical bond；Another kind of admixture is ash content, and it is the inorganic part of activated carbon, and ash content easily causes in activated carbonSecondary dirt Dye.During activated carbon is due to stronger adsorptivity, being widely used in producing, living；Absorbent charcoal material is by working process The amorphous carbon of gained, there is very big specific surface area, to the inorganic or organic substance in gas, solution and colloidal solid etc. all There is good adsorption capacity；The chemical property of absorbent charcoal material is stable, and high mechanical strength is acidproof, alkaline-resisting, heat-resisting, not soluble in water With organic solvent, use can be regenerated；Active carbon filter is the process for being retained the pollutant of suspended state in water, quilt The suspension of retention is filled in the space between activated carbon；The size of filtering layer pore scale and porosity, with activated carbon material granularity Increasing and increase.I.e. granularity of activated carbon is thicker, and the space that can accommodate suspension is bigger.It shows as filter capacity enhancing, receives Dirty ability increase, holding filth capacity increase；Meanwhile activated carbon filtering layer hole is bigger, suspension more can be deeper delivered to down in water Layer of active carbon filtering layer, under conditions of having protection thickness enough, suspension can be more trapped, and Shi Zhong lower floors filtering layer is more Crown_interception, the increase of unit holding filth capacity are played well；Activated carbon institute is come to the interception capacity of suspension possessed by activated carbon The surface area of offer；When flow velocity is low, the filter capacity of unit screens out effect mainly from activated carbon, and when flow velocity is fast, mistake Suction-operated of the filter ability from activated carbon granule surface, the granule surface area that activated carbon is provided in filter process is bigger, It is stronger to the adhesive force of suspension in water.According to the intermolecular forces of activated carbon molecule and contaminant molecule in adsorption process not Together, absorption can be divided into two major classes：Physical absorption and chemisorbed (also known as activated adoption)；In adsorption process, work as activated carbon Active force between molecule and contaminant molecule is referred to as physical absorption when being Van der Waals force (or electrostatic attraction)；When activated carbon molecule Active force between contaminant molecule is referred to as chemisorbed when being chemical bond.The adsorption strength of physical absorption is mainly and activated carbon Physical property it is relevant, it is substantially unrelated with the chemical property of activated carbon；Because Van der Waals force is weaker, to the structure of contaminant molecule Influence less, physical absorption can be analogized to coacervation by this power as intermolecular cohesion；Polluted during physical absorption The chemical property of thing remains in that constant；Because chemical bond is strong, the structure of contaminant molecule is had a great influence, therefore chemistry can be inhaled It is attached to regard chemical reaction as, it is the result of chemical action between pollutant and activated carbon；Chemisorbed generally comprise electronics to shared or Electronics shifts, rather than simple perturbation or weak polarization, is irreversible chemical reaction process；Adsorption process is pollutant Molecule is adsorbed to the process of the surface of solids, and the free energy of molecule can reduce, and therefore, adsorption process is exothermic process, is released Heat be referred to as heat of adsorption of the pollutant on this surface of solids；Because physical absorption is different with the active force of chemisorbed, it Heat of adsorption, the rate of adsorption, activation energy of adsorption, adsorption temp, selectivity, absorption the number of plies and absorbance spectrum etc. show Certain difference；The refined and decolouring that active carbon adsorption technology is used for the industry such as medicine, chemical industry and food at home is existing for many years History；Start the 1970s to be used for Industrial Wastewater Treatment；Production practices show that activated carbon is to micro quantity organic pollutant in water Adsorptivity with brilliance, it has good to industrial wastewaters such as textile printing and dyeing, dye chemical industry, food processing and organic chemical industries Adsorption effect；Generally, to the organic matter represented in waste water with overall targets such as BOD, COD, such as synthetic dyestuffs, superficiality Agent, phenols, benzene class, organochlorine, agricultural chemicals and petrochemicals etc., there is the removal ability of uniqueness；So active carbon adsorption Progressively turn into one of industrial wastewater two level or the main method of tertiary treatment；Absorption is that a kind of material is attached to another material Slow mechanism on surface.Absorption is a kind of interfacial phenomenon, and it is relevant with the change of surface tension, surface energy.Cause suction Attached promotion ability has two kinds, and a kind of is repulsive force of the aqueous solvent to hydrophobic substance, and another kind is affine suction of the solid to solute Gravitation.Absorption in wastewater treatment, majority are the results of both power comprehensive functions；The specific surface area and pore structure of activated carbon Its adsorption capacity is directly affected, when selecting activated carbon, should be determined according to the water quality of waste water by testing；Dyeing waste water is preferably selected Select the flourishing charcoal kind of transitional pore；In addition, ash content also has an impact, ash content is smaller, and absorption property is better；The size of adsorption molecule with Charcoal pore diameter is closer to more adsorbed；Adsorption density also has an impact to charcoal absorption amount；In finite concentration scope Interior, adsorbance is increased with the increase of adsorption density；In addition, water temperature and pH value also have an impact.Adsorbance is with water temperature Raise and reduce；Active carbon adsorption is to utilize porous activated carbon, one or more materials in water is attracted to activity Carbon surface and the method removed, removing object includes deliquescent organic substance, synthetic detergent, microorganism, virus and necessarily The heavy metal of amount, and can decolourize, deodorization, purification of air.
Current tellurian water environment crisis (crisis triggered due to the change of " water quality ") getting worse, to the mankind's Production and life bring many detrimental effects, for global development strategy, whether western developed country or develop Middle country, it all will progressively implement in full the strategy of sustainable development of environment；Water is to restrict a national economy and social development Key factor, water have its natural quality, economic attribution and social property, the ecological circulation concept (Water Recycling) of water It is widely accepted；China is the poor country of a water resource, and the Treatment and recovery of municipal sewage is that solve this The extremely effective method of problem, at all times, mankind's dado and occupy, water has become the important of China's economy and social development Restraining factors；Therefore, China's municipal sewage is carried out handling great realistic meaning.
