Abstract
The invention discloses a kind of reinforcings to adsorb clinker and preparation method thereof and purposes, and the present invention passes through physical modification, chemical modification and bio-modification using clinker as raw material, by clinker to get to absorption clinker is strengthened successively, specifically comprises the following steps:(1) physical modification:Clinker is modified using microwave, obtains the clinker that physical modification is crossed;(2) chemical modification:Acid solution or alkaline solution are added in the clinker that physical modification is crossed, after reaction, are washed till neutrality, it is dry, obtain the clinker that chemical modification is crossed;(3) bio-modification:In the clinker that bacterium solution addition chemical modification is crossed, carries out the biofilm of clinker and adsorb clinker to get to the reinforcing.It is provided by the invention to prepare the method for strengthening absorption clinker as raw material using clinker, it is possible to increase the specific surface area of existing clinker extends adsorption saturation time, promotes adsorption capacity, and effectively realizing the absorption to water and soil pollution object, conversion and degradation.
Description
Technical field
The present invention relates to the water and soil pollution object processing technology field of clinker, a kind of reinforcing absorption clinker and its system are particularly related to
Preparation Method and purposes.
Background technology
Coal burning and incineration process of domestic garbage will generate a large amount of clinkers.Currently, these clinkers are primarily as building
Low value-added product is made in the raw material of material, cement, concrete etc..Also small part clinker is applied to wastewater treatment, this
It is to have the characteristics that porosity height, large specific surface area, and contain a large amount of sial since clinker is the product through high temperature sintering
The substances such as hydrochlorate, features described above show that clinker is a kind of multifunctional material with absorption property, be clinker as adsorbing medium
Theoretical foundation has been established applied to the processing of water and soil pollution object.
Slag treatment waste water is a kind of wastewater processing technology of more environmentally friendly " treatment of wastes with processes of wastes against one another ", but at present using at clinker
It is mainly the physical absorption effect by clinker to manage waste water, and not yet adsorbing medium is used as to be applied to soil remediation.In practical work
In Cheng Yingyong, it is primarily present the defect of following three aspect:(1) specific surface area of clinker, which also has, increases space;(2) clinker absorption master
If physical absorption, chemical ion replacement is weak with chelation, can only play the role of temporarily being enriched with to some organic pollutions;
(3) the adsorption saturation duration of clinker is short, and adsorption capacity is insufficient, and the power of regeneration after saturation is weak, and there are pollutants for clinker
Desorption, need to often update filler, it is difficult to become plant, animal and microorganism growth and development medium.
Invention content
In view of this, it is an object of the invention to propose that clinker and the preparation method and application thereof, this hair are adsorbed in a kind of reinforcing
The bright specific surface area that can be increased existing clinker using clinker as the reinforcing absorption clinker that raw material obtains, is extended adsorption saturation time, carried
Its adsorption capacity is risen, the physical absorption of water and soil pollution object, chemistry and bioconversion and the medium of degradation are become.
Based on above-mentioned purpose, a kind of preparation method for strengthening absorption clinker provided by the invention, using clinker as raw material, by stove
Slag passes through physical modification, chemical modification and bio-modification and adsorbs clinker to get to reinforcing successively.
In some embodiments of the invention, include the following steps:
(1) physical modification:Clinker is modified using microwave, obtains the clinker that physical modification is crossed;
(2) chemical modification:Acid solution or alkaline solution are added in the clinker that physical modification is crossed, after reaction, are washed till
Neutrality, it is dry, obtain the clinker that chemical modification is crossed;
(3) bio-modification:In the clinker crossed of bacterium solution addition chemical modification, the biofilm of clinker will be carried out to get to described
Strengthen absorption clinker.
In the present invention, used clinker can be coal-fired clinker and dregs of incinerator, and coal-fired clinker is the bottom of coal-burning boiler
Slag, it is fluidized combustion bottom slag that main component, which has calcium oxide, iron oxide, silica, aluminium oxide etc., dregs of incinerator, mainly
Ingredient has silica, calcium oxide, magnesia, iron oxide, di-iron trioxide, aluminium oxide etc..
In some embodiments of the invention, in step (1), the condition of the microwave is:With 10~100% microwave
3~8min of Power Processing;The more or less aperture structure for improving clinker of microwave modification, some that can make inside clinker have
Machine object decomposes so that its specific surface area improves, to which absorption property is reinforced.
In step (2), the acid solution be sulfuric acid solution, a concentration of the 30~60% of the sulfuric acid solution;It is described
Alkaline solution is NaOH solution, and the molar concentration of the NaOH solution is 3~10mol/L.
In the present invention, under thermokalite environment Na ions combined with clinker generate some Na salt compounds or with Si, Al
Etc. forming spatial skeleton structure.Na elements generate Na salt, Na zeolites point with the mineralogical composition in clinker under heated alkaline environment
Son sieve or spatial skeleton structure.
In some embodiments of the invention, in step (2), stove that acid solution or alkaline solution are crossed with physical modification
The liquid-solid ratio of slag is 1:1~2:1, unit mL/g;
When carrying out the chemical modification using acid solution, the time of the reaction is 10~18h, and temperature is room temperature;
When carrying out the chemical modification using alkaline solution, time of the reaction is 9~12h, temperature is 110~
150℃。
In the present invention, described to be washed till neutral concrete operations and be:It is rinsed to washing lotion and is in neutrality repeatedly with distilled water.It is described
Utilization can be prepared repeatedly by the compound concentration of above-mentioned steps using the washing lotion of distilled water flushing after chemical modification, make washing lotion to reach
