Abstract
The invention discloses a kind of Modified Iron CHARACTERISTICS OF TAILINGS SANDs, according to parts by weight, are formed by modification after the mixing of following raw material: antibiotic bacterium dregs or 2-5 parts and 3-8 parts of iron tailings sand of biogas residue.Modified Iron CHARACTERISTICS OF TAILINGS SAND absorption property is stablized, and is influenced by pH value and temperature small；The absorption property to heavy metal ion and phosphorus is increased substantially compared to unmodified iron tailings sand, moreover it is possible to turn waste into wealth while removing the antibiotic residue in antibiotic bacterium dregs；The present invention also provides a kind of preparations of Modified Iron CHARACTERISTICS OF TAILINGS SAND, and to be had excellent performance, porosity is high, and the remaining Modified Iron CHARACTERISTICS OF TAILINGS SAND of antibiotic-free provides suitable preparation process；The present invention also provides a kind of application of Modified Iron CHARACTERISTICS OF TAILINGS SAND, by the programs such as being granulated, further make that it is suitable for mercury improvement, and the further clean effect of promotion Modified Iron CHARACTERISTICS OF TAILINGS SAND.
Description
Technical field
The present invention relates to resource and environment protection technique field, in particular to a kind of Modified Iron CHARACTERISTICS OF TAILINGS SAND is prepared and its is answered
With.
Background technique
Currently, heavy metal pollution problem is increasingly valued by people with the fast development of industrial or agricultural, country's publication
" water prevention and cure of pollution action plan " i.e. " ten, water ", highlight the heavy metal pollution and prevention and treatment in water environment.Heavy metal wastewater thereby
Processing mode mainly has chemical precipitation method, electrolysis method, ion-exchange, absorption method, biological treatment and membrane separation process, absorption method
Because its is simple and easy, high efficiency is widely used in wastewater treatment.But conventional adsorbent such as active carbon, ion exchange resin
Deng expensive and be difficult to regenerate.The research of the alternative materials of Cheap highly effective and its practical engineering application are increasingly by people
Attention.
Iron tailings sand is Iron Works Plant under the conditions of particular technology, and iron ore is levigate, is discarded after choosing " useful constituent "
Waste.The annual make of refuse in China has reached 10,000,000,000 tons or more, and is in increase trend year by year.A large amount of iron tailings sand are idle
Accumulation is difficult to manage, and land occupation results in waste of resources simultaneously, therefore how to become the important of scientific research personnel using iron tailings and ask
Topic.Iron tailings sand can be used for light heat-insulation and heat-preservation material, cement, ceramic material, it is also possible to make soil conditioner and microelement
Fertilizer.Large specific surface area, easily settled after iron tailings sand is sorted, while it being rich in a large amount of basic anhydride and silicide, meet and makees
For the condition of adsorbent in water.By many experiments, it is found that iron tailings sand has suction to heavy metal ion copper, lead, chromium, cadmium, lead etc.
Attached ability, but absorption property have it is to be optimized.
Summary of the invention
It is an object of the invention to solve at least the above problems, and provide the advantages of at least will be described later.
It is a still further object of the present invention to provide a kind of Modified Iron CHARACTERISTICS OF TAILINGS SANDs, and absorption property is stablized, by pH value and temperature
Influence it is small；The absorption property to heavy metal ion and phosphorus is increased substantially compared to unmodified iron tailings sand, moreover it is possible to will resist
Antibiotic residue in raw element bacteria residue is turned waste into wealth while removal；
It is a still further object of the present invention to provide a kind of preparations of Modified Iron CHARACTERISTICS OF TAILINGS SAND, to be had excellent performance, porosity
Height, and the remaining Modified Iron CHARACTERISTICS OF TAILINGS SAND of antibiotic-free provides suitable preparation process；
It is a still further object of the present invention to provide a kind of applications of Modified Iron CHARACTERISTICS OF TAILINGS SAND, by programs such as granulations, further
Make that it is suitable for mercury improvement, and further promotes the clean effect of Modified Iron CHARACTERISTICS OF TAILINGS SAND.
In order to realize these purposes and other advantages according to the present invention, a kind of Modified Iron CHARACTERISTICS OF TAILINGS SAND is provided, by weight
Number meter is formed by modification after the mixing of following raw material: antibiotic bacterium dregs or 2-5 parts and 3-8 parts of iron tailings sand of biogas residue, wherein institute
Stating biogas residue is the solid portion that antibiotic bacterium dregs anaerobic fermentation residues obtain after being separated by solid-liquid separation.
A kind of preparation of Modified Iron CHARACTERISTICS OF TAILINGS SAND, comprising the following steps:
Step 1: by after drying antibiotic bacterium dregs or biogas residue and iron tailings sand respectively cross 40-80 mesh, it is spare；
Step 2: according to parts by weight, by after sieving 2-5 part antibiotic bacterium dregs or biogas residue mix with 3-8 parts of iron tailings sand
Close uniformly obtained mixture I；And
Step 3: the mixture I to be pyrolyzed to carbonization under anaerobic, with 8-10 DEG C/min's during pyrolysis carbonization
Speed is warming up to 300-700 DEG C, and Modified Iron CHARACTERISTICS OF TAILINGS SAND is made in the 1-4h of heat preservation pyrolysis later.
Preferably, further comprising the steps of:
Step 4: the Modified Iron CHARACTERISTICS OF TAILINGS SAND described in water repeated flushing to its pH value is in neutrality, dries later, crushes, crosses 40-
Neutral modification iron tailings sand is made in 80 meshes；
Wherein, the temperature dried in the step 1 and the step 4 is 80-105 DEG C.
A kind of application of Modified Iron CHARACTERISTICS OF TAILINGS SAND in water process.
