Remelted lead is an important way to reuse the waste and to prevent lead pollution but it may produce soil lead pollution without appropriate treatment 再生铅冶炼是对废弃物的循环利用,防治铅污染的重要手段。
Based on the case study of soil environmental impact assessment of remelted lead , approach on methods of qualitative analysis of soil environmental status and assessment and prediction were discussed 再生铅冶炼对土壤环境的影响,首先进行环境影响识别,并根据冶炼中铅的排放强度和铅的生物地球化学循环规律来阐明其排放特点和进入土壤的途径。
Next , it analyzes the weaknesses in the aspects of low industry concentration , reduced resource arrangement efficiency due to unfair competition , laggard technology of recycled lead production , small ratio of deep - processing products . finally , it studies the countermeasures of lead and zinc metallurgy industry in china in the aspects of country , industry and company 从行业集中度低、不公平的竞争降低了资源配置效率、再生铅工业水平落后、产品深加工比例小等方面分析了行业发展的劣势;从国家、行业、企业三个层面研究了发展我国铅锌冶炼行业的对策。
