综述了有色金属工业中的砷污染以及砷资源的综合利用。砷品主要用于木材防腐和防治白蚁。
The pollution of arsenic in non ferrous industry and the methods preventing the pollution are reviewed in the present paper. In China there are about 30 000 T arsenic every year being put into smelteries.But most of them can not be utilized effectively.So it is very important to find a way to utilize arsenic comprehensirely.Arsenic is mainly used in wood antiseptics and termite prevention. The present status and the importance of wood antiseptics and termite prevention are then reported. Wood antiseptics containing arsenic is discussed in detail. There are four generations of antiseptics, and the former three are ZMA, CZA, CuCZA. The fourth generation consists four types, which are FCAP, ACA, CCA and ACZA. CCA is used most widely and is most effective at present.The performances and characteristics of wood antiseptics containing arsenic are then given. They are wide scope of aplication,good antiseptic effect,convinient to deal with the wood,no second pollution and low cost.The trend of utilization of wood antiseptics containing arsenic is analyzed briefly. In the end, the countermeasures for arsenic prevention are presented. They are curing and packing, comprehensive utilization, direct utilization and the development of wood antiseptics containing arsenic.
