我国锑采选行业废水治理技术研究

Research on Wastewater Treatment Technology in Antimony Selecting Industry in China

锑矿属于有色金属中的小金属矿种。随着我国锑的总需求量和总产量都在逐年增长,对环境的污染也随之加剧。锑采选过程中产生的废水,是造成水体污染的来源之一。锑采选过程中会产生的废水,其中影响最大的污染物为锑、砷、铅、镉、锌等重金属,如果处理不当,将污染地表水、土壤、地下水及农作物,造成不可逆的危害。本文在研究我国锑采选行业发展现状、生产工艺及废水特点的的基础上,介绍了国内锑采选行业废水的主要治理技术,并提出笔者关于锑采选行业的一些展望。

The antimony deposit belongs to the small metal non-ferrous metal minerals.With Chinaˊs antimony aggregate demand and output increasing year by year,the pollution to the environment is also increasing.The waste water produced in the process of selecting Antimony is one of the sources of water pollution.The great pollutants produced in selecting antimony are antimony,arsenic,lead,cadmium,zinc and other heavy metals.If not handled properly,the pollution of surface water,soil, groundwater and crops,will cause irreversibledamage.This paper introduces domestic antimony selecting industry from wastewater based on the development situation of the selecting antimony industry,production process and characteristics of wastewater and also puts forward some prospect for the industry.
