Description
Technical field
The invention belongs to beryllium-containingsewage sewage process field, beryllium copper sewage disposal side that is more particularly to a kind of while removing beryllium and copper
Method.
Background technology
Beryllium copper is a kind of supersaturated solid solution acid bronze alloy, is mechanical performance, physical property, chemical property and etch resistant properties
The non-ferrous alloy of good combination, through be dissolved and ageing treatment after, have the high intensity limit comparable with special steel, elastic limit,
Yield limit and fatigue limit, while but also with thering is high conductivity, thermal conductivity, high rigidity and wearability and high creep to resist
Power and corrosion resistance are widely used in manufacturing all kinds of mold inserts, substitute steel and make precision height, complex-shaped mold, weldering
Receiving electrode material, die casting machine, injection molding machine punch, wear-and corrosion-resistant work etc..Beryllium copper band be applied to micro-motor brush, mobile phone, battery,
It is the indispensable essential industry material of the development of the national economy on product.Therefore, the generated sewage in beryllium copper production process
Experimental study is handled, this has very real meaning.
Containing a large amount of beryllium and copper in produced sewage in beryllium copper production process, by simple copper-removing method, after processing
Sewage in have an a large amount of beryllium, and rely on single except the method for beryllium, parameter and equipment can not meet except the copper in decontaminated water.
Xu Xuejun is disclosed on 2006-the five national rare metal seminars at a kind of trade effluent containing beryllium
Reason method, is neutralized using sodium hydroxide, adds in flocculant PAC and PAM, finally reaches the qualified discharge of processing by filtering twice,
But the method is not appropriate for high-content beryllium and the simultaneously sewage disposal containing regional high background, and when beryllium content is more than certain value,
PH=8.5 can not completely settle in inclined plate.Except there are many sewage containing copper method, but these methods cannot all remove industry simultaneously
The middle beryllium of waste water.In addition this method is not suitable for the beryllium copper sewage disposal containing+6 valency chromium.
Invention content
The present invention seeks to be directed to the shortcoming of existing beryllium copper sewage water treatment method, a kind of sewage disposal containing beryllium copper is provided
The method for removing beryllium and copper simultaneously in technique.
A kind of method for removing beryllium and copper simultaneously in sewage treatment process containing beryllium copper, this method is mainly by following steps
Composition：
（1）Beryllium copper sewage lifting flow 20-60m will be contained3/h；
