Abstract
Relating to the field of water treatment materials, the invention specifically relates to a red mud coated adsorption material for removing inorganic pollutants and a preparation method thereof. Red mud is adopted as the absorptive active component and a hard material is employed as the carrier. The surface of the hard material is coated with the absorptive active component red mud through a particular proportioned binder. After drying and washing of the coated material, a red mud coated adsorption material for removing phosphor and heavy metals can be obtained. With simple operation, the preparation process of the invention is suitable for on-site preparation and usage. With the industrial slag waste red mud as the raw material, the adsorption material provided in the invention can have a low price. As the raw material red mud adopted in the invention is rich in a plurality of absorptive active components of metallic oxides, so the application of the red mud coated adsorption material provided in the invention to remove inorganic pollutants can achieve efficient removing effect.
Description
Technical field
The present invention relates to the material for water treatment field, specifically is that a kind of red mud cladded type inorganic pollution is removed sorbing material and preparation method thereof.
Background technology
The granule adsorbent absorption method is the important method that inorganic pollution is removed in the water, and the granule adsorbent performance is the key factor of decision to phosphorus and heavy metal removal effect.The water treatment particulate adsorbent material that is used for the removal of water inorganic pollution generally has two kinds, first kind is the granule adsorbent that adopts the direct granulation of adsorption activity component to make, second kind is that the adsorption activity component is carried on the granule adsorbent that carrier surface is made, the granule adsorbent active component utilization rate that direct granulation is made is low, the adsorbent activity component utilization rate height that active constituent loading is made in carrier surface.Be used for the load type adsorbing agent that the water inorganic pollution is removed at present, load active component comprises activated alumina, iron carbonyl, zirconia, cerium oxide, lanthana etc., and these component price general chargeds are higher, and the practical application cost is higher.
Red mud is the residue that produces in the aluminum oxide production process, is cheap raw material, and red mud contains the oxide of abundant iron, aluminium and calcium simultaneously, is the active principle that inorganic pollution absorption is removed in the water.It is active component that the present invention adopts the cheap material red mud, with the hard material is carrier, adopt certain proportion particular types binding agent that adsorption activity component red mud is coated with certain proportion and be carried on the hard carrier material surface, drying, washing obtain the red mud cladded type and remove the inorganic pollution sorbing material.It is active component that this material adopts red mud, and red mud is cheap and easy to get and to be adsorbed with effective component content abundant, and therefore not only usefulness is good but also with low cost for made sorbing material.
Summary of the invention
The purpose of this invention is to provide a kind of is that the red mud cladded type inorganic pollution of adsorption activity component is removed sorbing material and preparation method thereof with the cheap material red mud, for achieving the above object, the invention provides following technical scheme: be the adsorption activity component with the red mud, with the hard material is carrier, adopt certain proportion particular types binding agent that adsorption activity component red mud is coated with certain proportion and be carried on the hard carrier material surface, drying, washing obtain red mud cladded type inorganic pollution and remove sorbing material.
Preparation process involved in the present invention is easy and simple to handle, is fit in situ preparation and uses.
The present invention adopts industrial slag refuse red mud to be raw material, and is cheap.
Be rich in multiple metal oxide adsorption activity composition in the raw material red mud that the present invention adopts, be used for the water inorganic pollution and remove, can obtain efficient removal effect.
The specific embodiment
Below in conjunction with instantiation the specific embodiment of the present invention is described:
Take by weighing 500g particle diameter 1-2mm quartz sand as hard carrier; it is mixed with the 50g red mud and drop in the rotary pelleting machine and rotate; dripping 25ml concentration is that 1% carboxymethyl cellulose aqueous solution is a binding agent; dropwise and continue rotation 5 minutes; gained sample room temperature is air-dry; air-dry after washing, obtain final products.Products obtained therefrom is used for dephosphorization, and adsorbance reaches 20mg/g, is used to remove chromium, cadmium, arsenic, nickel, and adsorbance reaches 25mg/g.
