摘要

摘要: 介绍了我国电解锰行业发展及清洁生产审核的推进情况,通过在电解锰行业开展数轮清洁生产审核,诊断出该行业存在的主要环境污染问题,在行业内建立了规范化的管理制度,推动了清洁生产技术的发展,分析了典型中高费方案实现的环境效益和经济效益。结合电解锰行业清洁生产指标体系,重点分析了2009—2017年行业的有毒有害物质的替代、综合能耗、电流效率等关键性清洁生产指标的变化情况。结果显示,综合能耗由2009年的8 600 kW·h/t(以Mn计,下同)降至目前的6 900 kW·h/t,电流效率总体呈上升趋势。对于经过多轮审核的某企业,其电解槽、剥离方式、直流电耗、锰渣无害化处理和综合利用率、锰渣中水溶性锰浓度(以干基计)等5项评估指标均达到国内领先水平,在行业处于顶尖水平,另一项指标单位产品新鲜水耗也有明显下降,为行业节能减排起到引领作用。

Abstract: The development of the electrolytic manganese industry in China and the progress of its cleaner production audit were introduced. Through several rounds of cleaner production audit in the electrolytic manganese industry, the major environmental pollution problems in the electrolytic manganese industry were diagnosed. The standardized management system was established in the industry, the development of cleaner production technologies promoted, and the environmental benefits and economic benefits of typical medium and high fee options analyzed. Combined with the cleaner production evaluation index system of the electrolytic manganese industry, the variation of key cleaner production indexes such as the replacement of toxic and hazardous substances, comprehensive energy consumption and current efficiency in the industry from 2009 to 2017 was analyzed. The results showed that the comprehensive energy consumption had decreased from 8 600 kW ·h/t (in Mn) in 2009 to 6 900 kW ·h/t currently, and the current efficiency had shown an overall upward trend. For a company that had undergone multiple rounds of cleaner production audit, five evaluation indexes such as electrolytic cell, stripping method, DC power consumption, harmless treatment of manganese slag, and synthesis utilization rate and water-soluble manganese content (dry basis) in manganese slag reached the domestic advanced level, and played a leading role in energy conservation and emission reduction of the industry.
