Description
Technical field
The present invention relates to water-treatment technology fields, and in particular to be superpower absorbent-type polyaluminium aluminium base flocculant.
Background technique
Due to the shortage of freshwater resources, water reuse becomes particularly important, and how impurities in water effectively removes then
It is the emphasis of research.Coagulant sedimentation has the advantages that economical and efficient, simple process and easy to operate, be widely used in water and
In wastewater treatment.Either city and industrial water supply processing or city and Industrial Wastewater Treatment, all using coagulating sedimentation as work
Indispensable sport technique segment in skill process.And the quality of coagulating treatment effect depends greatly on the product of coagulant
Matter.Coagulant belongs to the water treatment agent of high added value and high-tech content, it largely decides water treatment technology
Innovation and development, the simplification of process flow, the height of operating cost and purification of water quality quality superiority and inferiority.Traditional sewage treatment
Although method has certain catharsis to industrial wastewater, being difficult, which makes to handle water, reaches increasingly strict sewage discharge mark
It is quasi-.Therefore, development, exploiting economy, safety and efficient coagulant, to seek the effective ways of processing industrial wastewater be at water always
The pillar industry given priority in reason environmental technology field.
With the economic development and improvement of people's living standards, the water quality of city domestic sewage becomes to become increasingly complex,
Requirement to water treatment agent complex function is higher and higher.Therefore, flocculant should also kill in addition to excellent flocculating property
Bacterium, removes the multiple functions such as COD, sustained release at decoloration.There is the shortcomings that being hard to avoid in inorganic flocculating agent, including dosage is big, settling of floccus
Slowly, inconvenient to use, residual toxicity is big etc..It is inorganic mutually to compensate for deficiency with organic composite flocculant but existing inorganic
With organic flocculant collocation using can realize separation of solid and liquid to the waste water of general slight pollution, sometimes to the waste water of high density pollution
Basic separation of solid and liquid target is also difficult to reach, although in addition, the biggish aluminium polychloride of dosage is to the coloration for improving waste water
Polyacrylamide is used alone in high concentrtion, height very well but there are the remaining environmental problem of the larger brought aluminium of dosage in effect
The occasion flocculating effect of concentration industrial wastewater is poor, in current sewage treatment industry, still lacks efficient, cheap, more function so far
The flocculant of energy.
The adsorption capacity of traditional flocculant is smaller, more effective to particle biggish in absorption effluent, it is difficult to remove decontamination
Micropollutants in water.Various adsorbents such as crystalline mineral, cigarette ash, biomaterial, silica gel, sawdust, fruit shell, active carbon etc. is
Developed and for go water removal in micropollutants.But limited adsorption capacity limits the application of these adsorbents.Therefore, people
Seeking always have bigger adsorption capacity, more effective novel absorption material.
The interaction of humic acid and pollutant may include anion exchange, hydrogen bond, surface coordination exchanges, cation bridged bond
Etc. all various aspects.Humic acid large specific surface area, high surface activity, absorption property, coordination ability are also relatively high.But humic acid is easy
It is dissolved in water, it is difficult to be separated from the water.
Powdered Activated Carbon all has excellent adsorption capacity to methylene blue, cationic red, basic fuchsin and phenol etc..But
Powdered Activated Carbon size is small, and is easily dispersed in water, after being used as adsorbent absorption water pollutant, it is difficult to it is removed from water,
To bring secondary pollution problem.
Summary of the invention
The purpose of the present invention is superpower absorbent-type polyaluminium aluminium base flocculant, this superpower absorbent-type polyaluminium aluminium base
Flocculant is used to solve to go out when the alumen ustum that aluminium salt generates in current sewage treatment is light, low-temperature and low turbidity purifying water effect is poor, dosage is excessive
Existing muddy problem, and alleviate adsorbent and be difficult to the problem of being separated by solid-liquid separation.
The technical solution adopted by the present invention to solve the technical problems is: this superpower absorbent-type polyaluminium aluminium base flocculation
Agent is prepared by the humic acid by 20-40% based on mass fraction, the aluminium polychloride of the active carbon of 20-40%, 20-50%,
The humic acid, Powdered Activated Carbon, aluminium polychloride are configured to the slurry that mass concentration is 50-80%, are vigorously stirred uniformly,
Quiescent setting is separated by solid-liquid separation after its supernatant is clarified completely；Solid portion is dried in vacuo to obtain black powder solid, institute
Stating black powder solid is superpower absorbent-type polyaluminium aluminium base flocculant.
Content of humic acid is 30% in above scheme, activated carbon content 30%, and polyaluminium aluminium content is 40%.
Al in aluminium polychloride in above scheme2O3Content is 25-30%.
Humic acid is handled using ethanol purification in above scheme, purity 95-98%.
Active carbon is Powdered Activated Carbon in above scheme.
The invention has the following advantages:
1, the present invention provides a kind of composite flocculation for sewage treatment that can play flocculant, adsorbent surface synergistic effect
The characteristics of agent, which combines flocculant and adsorbent, the alumen ustum for not only solving aluminium salt generation is light, low-temperature and low turbidity water purification
The shortcomings that becoming turbid when effect is poor, dosage is excessive, and alleviate adsorbent and be difficult to the shortcomings that being separated by solid-liquid separation.
2, the present invention is nontoxic, reaction speed is fast, applicable pH range is wide, coagulation effect is good, in water supply, wastewater treatment, weaving
Printing and dyeing, mining, daily-use chemical industry, the especially fields such as heavy metal pollution can widely apply, and null solution is inhaled, and secondary pollution is not present.
