我国黑色金属矿采选业的产排污及治理现状

Current Situation of Pollution Generation,Discharge and Treatment of Ferrous Metal Ore Mining and Dressing Industry in China

黑色金属矿采选业是我国的重要基础产业,对国民经济的发展起着不可替代的作用,但带来的环境污染问题也相当严重。本文结合第二次全国污染源普查,对黑色金属矿采选业进行调研,并分析行业产排污现状,为行业产排污核算奠定基础。本次调研明确了黑色金属矿采选过程的产排污现状、影响因素及主要治理工艺,有助于识别产排污节点,核算行业产排污量。

Ferrous metal ore mining and dressing industry is an important basic industry in China,which plays an irreplaceable role in the development of the national economy,but it also brings about serious environmental pollution problems.Based on the second national survey of pollution sources,this paper investigates the ferrous metals ore mining and dressing industry,analyzes the current situation of industrial pollution generation and discharge,so as to lay a foundation for industrial pollution generation and discharge accounting.The survey clarifies the current situation of pollution generation and discharge,influencing factors and main treatment processes in the mining and dressing process of ferrous metal ores,which is helpful to identify the pollution generation and discharge nodes and calculate the industrial pollution generation and discharge.
