Description
Technical field
The present invention relates to a kind of method that utilization aluminium scrap lime-ash prepares composite water purifying agent, belong to water purification agent technology of preparing neck
Domain.
Background technology
Aluminium ash is mainly generated during aluminum oxide produces aluminium through molten-salt electrolysis, due to operating and measuring instrument is taken
Band, anode change, go out the reasons such as aluminium, ingot casting and electrolytic cell overhaul, substantial amounts of aluminium slag can be produced.Typically often producing 1 ton of aluminium will
Produce 3050 kilograms of aluminium slag aluminium ashes.In recent years, China's aluminium production capacity and yield are increased considerably.Again, aluminium scrap regeneration is laid equal stress on
The rate of recovery of new fabricated product is generally 75%~85%.1 ton of aluminium scrap of regeneration will produce 150~250 kilograms of aluminium slag aluminium ashes.Aluminium lime-ash
It is a kind of renewable resource, but does not obtain one of enough attention, the factor as welding always.With economic hair
Exhibition, aluminium scrap lime-ash accumulation is increased considerably year by year, if the method for not finding economical and effective and environmental protection is administered, its is right
The serious threat of environment will be highlighted increasingly.The grey Slag treatment rate of recovery of China's aluminum current is low, and energy expenditure is big, and research and development will
Industrial aluminum lime-ash reclaim prepares other materials, for increasing economic efficiency, preserve the ecological environment have important practical significance with
Practical value.
Water purification agent is exactly to deliver energy and other aitiogenic medicaments of impurity in water in water.Mainly play the mesh of water purification
's.Water purification agent is generally produced using flyash at present, but this method is high due to flyash production temperature, aluminium element therein is very
Hardly possible is leached with strong acid, and cosolvent fluoride need to be added to improve the extraction rate of aluminium, and processing cost is improved due to introducing fluoride,
And new solid waste can be produced during production water purification agent, the solid waste is the raw material for producing sodium metasilicate again, or production is in vain
The raw material of carbon black and zeolite, equipment and raw material that its post-order process need to be new, post-processing is complex and high cost.Therefore one is worked out
The method that water purification agent is prepared using aluminium scrap lime-ash is planted, with important practical value.
The content of the invention
The technical problems to be solved by the invention：Low for the grey Slag treatment rate of recovery of aluminum current, energy expenditure is big, pollutes ring
Border, and current water purification agent can produce new solid waste in Water treatment, the drawbacks of post-processing is complicated, cost is high is carried
One kind has been supplied using aluminium scrap lime-ash as raw material, has filtered and air-dries after being mixed with distilled water, limestone powder calcining has been added and is ground into particle,
Mixed with sulfuric acid, manganese dioxide heating, standing filters to get filtrate, and adds ferric sulfate and glycerine heating stirring, adds sodium oxide molybdena
Hydrolytic polymerization, stands curing, mixes and is produced up to without precipitation with distilled water, filters to obtain filtrate, and drying, which is crushed, to be made
The method of composite water purifying agent.The present invention is high to the grey Slag treatment rate of recovery of aluminium, and products obtained therefrom is consolidated in Water treatment without any new
Body waste is produced, and purifying water effect is good.
In order to solve the above technical problems, the present invention is using technical scheme as described below：
