水泥生产过程主要化学毒性水溶性铬(Ⅵ)来源监测与防治建议

Risk Monitoring and Prevention Suggestions for the Main Chemical Toxicity of Water-soluble Chromium(VI)in the Cement Production Process

水泥属于传统建筑材料在国内已经使用一百多年,与人们的生活紧密相关,目前水泥的发展已经相当成熟,其不仅在使用性能层面,在绿色安全环保层面也有比较严格的要求。现今大部分水泥原料采用废物利用,虽然成本节约了但是随之而来的毒性问题也在困扰着人们,而毒性的主要来源是水溶性六价铬,因此对水溶性六价铬源头研究和防治迫在眉睫,文中主要介绍了国内对水泥中水溶性六价铬的来源研究以及防治措施,进而提出对水泥未来发展的展望。

Cement is a traditional building material that has been used for more than 100 years in China and is closely related to people’s life.At present,the development of cement has been quite mature.It has strict requirements not only in terms of service performance,but also in terms of green,safety and environmental protection.Nowadays,most cement raw materials come from waste utilization.Although the cost has been saved,the following toxicity problems are also puzzling people.The main source of toxicity is water-soluble hexavalent chromium,so it is urgent to study and prevent the source of water-soluble hexavalent chromium.This paper mainly introduces the domestic research on the source of water-soluble hexavalent chromium in cement and the prevention and control measures,and then puts forward the prospects for the future development of cement.
