Description
Technical field
The present invention relates to a kind of preparation method of bagasse active carbon/ferric oxide.
Background technology
Phosphorus has negative effect again to environment and the existing positive influences of human health.For example, an amount of phosphorus helps the growth of crops, but phosphorus is excessive in the river, lake; To make water quality trend eutrophication, and cause a large amount of evil of various algae and pasture and water to be given birth to, water quality is muddy; Water hypoxia; Aquatiles such as fish are dead, destroyed the ecological balance of the earth, and existent environment of people is on the hazard.Therefore, the recovery of waste water dephosphorization and phosphorus is an important goal of present water treatment research.The removal method of phosphorus mainly contains in the water at present: bioanalysis, chemical precipitation method, artificial swamp method, ion-exchange and absorption method etc.Bioanalysis and chemical precipitation method can produce a large amount of phosphorous excess sludges, have improved processing cost, and the recovery of phosphorus also has certain difficulty.The artificial swamp method is not high to the removal efficient of phosphorus, and its processing cost of ion-exchange is higher.In recent years, Many researchers is with the direction of absorption method dephosphorization as research.Adsorbent commonly used has: FeOOH, goethite, titanium dioxide and activated alumina etc., mostly this type of adsorbent is Powdered, though specific area is big, helps the absorption of phosphorus, can make the phosphorus concentration of handling the phosphorous water sample in back be lower than 0.50mgL
-1, reach town sewage and handle pollution discharge standard (GB18918-2002).But Separation of Solid and Liquid is difficult, is unfavorable for the recovery of phosphorus and the regeneration of adsorbent.Active carbon is a kind of adsorbent of function admirable, and at present, in the town sewage treatment process, granular activated carbon is mainly used in the removal of colourity.The preparation of active carbon/ferric oxide composite also has a small amount of bibliographical information and is used for the absorption research of arsenic, but up to now, is primary raw material with bagasse, and the preparation bagasse active carbon/ferric oxide does not appear in the newspapers.
Summary of the invention
The object of the invention is exactly to adopt the precipitation method and calcination method at normal temperatures and pressures, is primary raw material with bagasse, is auxiliary material with iron chloride and ammoniacal liquor, the preparation bagasse active carbon/ferric oxide.
At present, study in the sorbing material of more adsorption and dephosphorization, single material has FeOOH, goethite, titanium dioxide and activated alumina etc.; Compound material has active carbon iron oxide, charing eggshell-iron oxide complex, fragrant citrus pericarp load zirconium, lanthanum, germanium, ferrous metal etc.The main component of the sorbing material that has in these sorbing materials is an iron-aluminium oxide, and they also are the main matter of absorption phosphorus, and the main component in the part sorbing material is some organic substances such as active carbon.Low in order to overcome existing dephosphorization adsorbent adsorption capacity, adsorption capacity is limited, and makes full use of the abundant bagasse resource in Guangxi.The present invention provides a kind of preparation method of dephosphorization sorbing material bagasse active carbon/ferric oxide.This dephosphorization sorbing material, bagasse active carbon/ferric oxide can not only make the phosphorus concentration of handling the phosphorous water sample in back be lower than 0.50mgL
-1, and adsorption capacity is big, when the initial phosphorus concentration of phosphorous water sample is lower than 2.0mgL
-1After the adsorption equilibrium in the water sample phosphorus concentration be lower than 0.1mgL
-1, simultaneously, because active carbon is the major product that the bagasse pyrolysis obtains; Because of it has special microcellular structure and biological characteristics, bagasse active carbon can improve pH in soil, enriches the constituent contents such as nitrogen, phosphorus, potassium, calcium and magnesium of soil; Reduce content of beary metal such as ZINC IN SOIL and copper, improve the porosity and the unit weight of soil, prolong the growth period of plant; Strengthening plant high temperature resistance, drought-resistant ability, is a kind of cheapness and environment-friendly material.
Concrete steps are:
(1) with bagasse in baking oven 80 ℃ of following dry for standby;
(2) in the 2L beaker, add 800ml distilled water, add the cetrimonium bronmide 100ml of 0.01mol/L～0.1mol/L again, heated and boiled; Under agitation slowly drip the ferric chloride solution 100ml of 0.5mol/L～2.5mol/L, get the brownish red colloid; In above-mentioned brownish red colloid, add 20g～60g step (1) gained bagasse, stir, left standstill 24 hours;
(3) step (2) product is used full-automatic titrator, under agitation, slowly adds volume ratio and be 1.0%～10.0% ammoniacal liquor and regulate pH to 7.4, bagasse/iron hydroxide mix suspending thing aqueous solution;
(4) step (3) gained bagasse/iron hydroxide mix suspending thing is filtered back drying under 105 ℃-110 ℃, get bagasse/iron hydroxide mixture;
(5) step (4) gained bagasse/iron hydroxide mixture is carried out charing respectively, gets the active carbon/ferric oxide compound under 400 ℃～600 ℃, grind then, cross 60 mesh sieves.
The present invention is simple for process, owing to utilize bagasse to be main raw material(s), reduces production costs greatly, and has improved product each item performance indications; Prepared product can be widely used in urban wastewater treatment firm dephosphorization production process.
