赤泥综合利用产业化现状、存在问题及解决方略探讨

Status-quo,problems and solutions of red mud comprehensive utilization

本文介绍了赤泥的排放情况及理化特性,总结了国内赤泥综合利用技术的产业化现况,指出赤泥综合利用产业化项目在应用实施过程中面临的问题是赤泥利用主体责任不强、资源化处置技术成本过高、产品标准缺失、市场认可度差、规模化应用受限、跨领域协同利用少等。最后,提出推进赤泥综合利用的几点建议:构建完善赤泥综合利用相关标准体系;加大产学研用联合攻关,进一步降低赤泥处置成本;搭建区域间固废合作平台,推动跨行业协同处置赤泥示范线建设。

In order to promote the industrial production of red mud,the emission and physicochemical properties of red mud were analyzed in this paper,and the current situation of red mud industrial application in China were summarized.It’s pointed out that the main problems in the industrial application of red mud are lack of corporate responsibility of red mud users,high cost of disposal technology,lack of product standards,poor market recognition,restricted large-scale application,and less cross-sector collaborative utilization.Finally,suggestions were given to promote the comprehensive utilization of red mud:namely,establishing red mud utilization and product standard system,strengthening industry-academic research cooperation to further reduce the cost of red mud disposal,establishing inter-regional solid waste cooperation platform and building demonstration lines for cross-domain collaboration in red mud disposal.
