利用近年国内7家大中型综合性有色金属加工厂的给水排水统计资料,分析铝加工、铜加工、稀有加工、硬质合金企业的给水排水指标。根据污染物排放系数分析确定主要污染企业及主要污染物。铜加工厂是有色金属加工企业中的水污染大户,其主要污染物是铜和石油类。 Using the statistical data of water supply and drainage of seven large and medium-sized integrated non-ferrous metal processing plants in recent years, this paper analyzes the indexes of water supply and drainage of aluminum processing, copper processing, rare processing, and cemented carbide enterprises. According to the analysis of pollutant emission factors to identify the major polluting enterprises and major pollutants. Copper processing plant is a large non-ferrous metal processing enterprises in water pollution, the main pollutants are copper and petroleum.
