对电解铝企业产生的阳极残渣、阳极残极浸出毒性进行了鉴别。鉴别结果表明：电解铝企业产生阳极残渣浸出液中氟化物（不含氟化钙）平均质量浓度为140 mg／L，最高达244 mg／L，且超标试样数达到《危险废物鉴别标准浸出毒性鉴别》中相应规定，鉴别该废物属于危险废物，应按照危险废物进行管理；阳极残极浸出液中氟化物（不含氟化钙）平均质量浓度为74 mg／L，无超标试样数，该废物不属于具有氟化物浸出毒性的固体废物，建议仍按一般固体废物进行管理。%The extraction toxicity of anode slime and anode scrap produced by electrolytic aluminum enterprises were identified in this article. Results showed that the average concentration of fluoride ( excluding calcium fluoride) in extraction solution of anode slime produced by electrolytic aluminum enterprises was 140 mg/L,with a maximum concentration of 244 mg/L,and the number of samples whose concentration exceeded the standard meets the corresponding requirements in “Identification Standard of Extraction Toxicity for Hazardous Waste”. The waste was identified and should be managed as hazardous waste; the average concentration of fluoride ( excluding calcium fluoride) in extraction solution of anode scrap was 74 mg/L without samples whose concentration exceeded the standard. The waste did not have the extraction toxicity of fluoride and is proposed to be managed as general solid waste.
