Description
Technical field
The utility model is related to a kind of graphene oxides and the composite modified zeolite filtration device of iron chloride, belong to graphite oxide
The innovative technology of alkene and the composite modified zeolite filtration device of iron chloride.
Background technology
With the quickening of China's process of industrialization, the pollution level in source quality is gradually deepened.At the same time, people couple
It is also being continuously improved with the requirement of water water quality.The new water standard in China increases 71 indexs in total, organic matter, heavy metal and
Microbiological indicator item number is all dramatically increased.Wherein organic compound index increase ratio accounts for 70%.And micro- Organic Pollutants
Index, especially low molecular weight dissolved organic matter are one of difficulties of water treatment field.These variations go out water supply plant
The requirement of water water quality is harsher.
Filter device used in existing conventional water treatment process process cannot meet the needs of people are to water standard,
Professional person obtains carrying iron modified zeolite thus using by applying iron in zeolite surface in the industry.Test result analysis obtains：It is modified
Zeolite is after modification than being before modified significantly improved to the adsorption capacity of fluorine.But its fluorine removal capacity and activated alumina, bone black
It waits defluoridation filter materials to compare not high, is unable to reach the purpose for substituting traditional defluoridation filter material, it is also necessary to improve iron by other methods
Load capacity and adsorption capacity.Also some professional persons are modified sand using graphene oxide, obtain GO-sand adsorbents.Experiment
The result shows that GO-sand is to methylene blue（MB）And Pb（II）Adsorption capacity and adsorbance obviously increase, be the 10 of roughing sand
It is more again.Hu etc. [15] research group be prepared for property it is stable and can the RNA-GO of stable dispersion in water, have studied it to drink
With micro toxin peptide in water（Microcapsule algae toxin）Absorption.As a result, it has been found that it, which is suitably applied absorption, is contaminated drinking water source
Trace contaminant in water quality.These Experiment Results illustrate that graphene oxide has good result for the processing of micro-polluted water,
But because graphene oxide involves great expense, directly the cost with graphene oxide-loaded filtrate is too high, is not suitable for high-volume industry
Production.
Utility model content
The purpose of this utility model is that considering the above problem and providing a kind of graphene oxide and iron chloride is composite modified
Zeolite filtration device, the utility model is at low cost, is suitble to the industrial requirement of high-volume, and load factor is high, load effect is good
It is good, there is extremely strong hydrophilicity and adsorption capacity.
The technical solution of the utility model is：The graphene oxide of the utility model and the composite modified zeolite filtration of iron chloride
Device, include natural zeolite, the gap that is not supported, iron oxide adsorption layer, graphene oxide layer, the appearance of natural zeolite
Face load has modified layer, which is, iron oxide interlaced together by iron oxide adsorption layer and graphene oxide layer
There is the gap not being supported between adsorption layer and graphene oxide layer.
For the utility model since the outer surface load using natural zeolite has modified layer, which adsorbed by iron oxide
Layer and the interlaced structure together of graphene oxide layer, the utility model is at low cost, and modified zeolite is probably day
3 to 10 times of right zeolite differ（It is still further preferred that 6 times）.It is suitble to the industrial requirement of high-volume.And load factor is high, load effect
Well, there is extremely strong hydrophilicity and adsorption capacity.The utility model is a kind of convenient and practical graphene oxide and chlorination
The composite modified zeolite filtration device of iron.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
Embodiment：
The structural schematic diagram of the utility model as shown in Figure 1, the graphene oxide of the utility model with iron chloride is compound changes
Property zeolite filtration device, includes natural zeolite 1, the gap not being supported 2, iron oxide adsorption layer 3, graphene oxide layer 4,
The outer surface load of natural zeolite 1 has modified layer, which is mutual by iron oxide adsorption layer 3 and graphene oxide layer 4
It is interleaved together, there is the gap 2 not being supported between iron oxide adsorption layer 3 and graphene oxide layer 4.
In the present embodiment, above-mentioned modified layer is supported on the outer surface of natural zeolite 1 by branch's high-temperature calcination.
In the present embodiment, above-mentioned iron oxide adsorption layer 3 is nanometer Fe2O3Particle.Above-mentioned nanometer Fe2O3The radius of particle is big
Small is 1 to 5nm.
In the present embodiment, the thickness of above-mentioned graphene oxide layer 4 is 0.8-1.6nm, and length of run is 20 μm.Expansion length
20 μm of degree refers to the length after used graphene oxide layer is fully deployed.
The operation principle of the utility model is：The be modified modified layer of zeolite surface of pollutant in raw water is adsorbed and is cut
It stays so that pollutant rests on the gap or surface of modified zeolite, to reach the pollutant concentration reduced in raw water
Purpose.
