Description
Technical field
The present invention relates to technical field of waste water processing, and in particular to a kind of composite modified alumino-silicate oiliness adsorbent and its
Preparation method and system.
Background technique
China's shortage of water resources, a large amount of industrial wastewaters and the unprocessed direct emission of sanitary sewage, make water pollution problems day
Beneficial serious, especially the persistence organic pollutant in water, majority have carcinogenic, teratogenesis, mutagenesis, easily in vivo
It is enriched with and is amplified by food chain, is finally detrimental to health.Cause the serious one of the main reasons of water pollution be the absence of it is economical,
The practical technique and new material of efficient treatment of Organic Wastewater.Natural clay, can be effectively at absorption due to its special structure
Persistent organic pollutants are managed, are had broad application prospects in wastewater treatment and environment remediation.It is developed to abundant
Using China's clay resource abundant, environment is protected, or even promotes the added value of clay series of products, increases foreign exchange earnings from exports and has
It is of great significance, there is significant economic benefit, environmental benefit and social benefit.
In wastewater treatment especially Industrial Wastewater Treatment, absorption method is a kind of important physico-chemical process.Often at present
Adsorbent is mostly active carbon, but because there is obvious shortcomings for acticarbon: supply is more nervous；Poor selectivity, adaptation
It is limited in scope；Generating apparatus is few again, costly, regeneration is difficult.Therefore, cheap, selective good, easy regenerated Series of Water is developed
The research of processing adsorbent has become one of the heat subject of wastewater treatment research field.
China's natural clay resource is very rich, from a wealth of sources, and cheap, clay has been widely applied to wastewater treatment
In.Although clay has the characteristics that dispersion performance is good, particle is small, large specific surface area, in water coloration, heavy metal ion, have
Machine object etc. has certain ion exchange adsorption effect, but low to the treatment effeciency of the organic wastewater of high concentration, difficult for biological degradation.
After physics and chemical modification processing, absorption property significantly improves clay.At present both at home and abroad to modified clay treatment waste water into
Go numerous studies, but most of modified clay can not handle high concentrated organic wastewater well, absorption property is poor.
How to find that a kind of wide adaptation range, absorption property be high, cheap adsorbent is at high concentrated organic wastewater
Reason field there is an urgent need to.
Summary of the invention
For overcome the deficiencies in the prior art, the purpose of the present invention is to provide a kind of composite modified alumino-silicate oiliness to inhale
Attached dose and preparation method thereof and system, sorbent particles exchange capacity of the invention is strong, effectively adsorbs heavy metal and organic waste
Water reduces the migration of organic pollutant in the environment, has excellent adsorption effect.
To solve the above problems, the technical solution adopted in the present invention is as follows:
A kind of composite modified alumino-silicate oiliness adsorbent comprising following raw material by mass percentage: aluminosilicate
Salt 47.6~82.6%, modifying agent 15~50%, sodium salt 2~5%, activator 0.2~2%, adhesive 0.2~2%.
As a preferred embodiment of the present invention, the modifying agent is stearic acid ammonium salt and/or stearic amide.
As a preferred embodiment of the present invention, the mixed proportion of the stearic acid ammonium salt and stearic amide is 3:7.
As a preferred embodiment of the present invention, the alumino-silicate is selected from clay, kaolin, bentonite, diatomite, water
Close one of sodium silicoaluminate calcium.
As a preferred embodiment of the present invention, the sodium salt be selected from one of sodium carbonate, sodium hydroxide, sodium chloride or
Any two or more mixing.
As a preferred embodiment of the present invention, the activator is selected from one of methanol, ethyl alcohol, isopropanol or any
Two or more mixing.
The present invention also provides a kind of preparation method of composite modified alumino-silicate oiliness adsorbent as described above, packets
It includes following steps: alumino-silicate is placed in mixing machine, then sodium salt is soluble in water, sodium salt solution is added into mixing machine, pass through
It crosses mixing machine to mix and squeeze, stearic acid ammonium salt, stearic amide, activator, adhesive is added in mixing machine, steam is protected
Temperature, uniform stirring squeeze, and drying squeezes out particulate matter, and grinding is made solid state powder or solid granulates, sieving to get.
As a preferred embodiment of the present invention, the holding temperature is 50~70 DEG C, soaking time is 0.5~1.5h；
The drying temperature is 80~100 DEG C, drying time is 15~60min.
The present invention also provides the production systems of composite modified alumino-silicate oiliness adsorbent as described above comprising mixed
