The Pb In Exhausted Water ion concentration belonged to discharged in smelting process is often higher, such as without processing, will be caused to environment greatly
Pollution, high risks will be also caused to the health lived in by the resident of lead contamination water head site.At present remove water in lead from
The main method of son has：Absorption method, the precipitation method, ion-exchange.Absorption method mainly have using high-strength polyvinyl alcohol chelate fibre,
The lead ion that the high material of the specific surface areas such as rice shell is gone in water removal by suction-operated.The precipitation method, which mainly have, utilizes hydroxy-apatite
Stone, aluminium polychloride or polyaluminium sulfate etc. are used as coagulant, in the basic conditions by precipitation go water removal in lead from
Son, it also can add enough sulfide and be removed by generating vulcanized lead sediment.Ion-exchange mainly utilizes some materials
Calcium ion in material reaches the purpose for removing lead ion with lead ion by ion exchange.Wherein absorption method is a kind of conventional side
Method, there is the advantages that simple to operate, removal efficiency is high.But selective absorption poor-performing of traditional adsorbent to lead, causes
Its adsorption effect to lead is influenceed very big by other coexistent impurity ions.In order to which obtain more excellent performance removes lead adsorption material
Material, in recent years, people have researched and developed manganese dioxide modified zeolite, starch/silicon dioxide hollow microsphere composite, cotton is born
Carry the new adsorbents such as zirconium oxychloride composite adsorbing material.
The content of the invention for obtain a kind of cheap, selective adsorption capacity it is strong remove lead adsorbent, the invention provides
A kind of NEW TYPE OF COMPOSITE sorbing material formed by aluminum phosphate hollow microsphere, rice hull ash for key component by granulation, and for going
Except the lead ion in lead waste water.
Formula is following (each component is mass percent)：
