摘要
钢渣作为一种二次资源,可实现资源化利用,但目前钢渣利用率较低,已对生态环境造成危害。本文结合某钢渣资源化企业场地环境调查数据,分析场地内堆存钢渣、土壤以及地下水的污染特性,为钢铁企业场地环境治理提供参考。经检测,钢渣样品pH严重超标,均大于11.83;土壤的挥发性有机物、半挥发性有机物以及重金属等45项常规检测指标均未超标;地下水中,除pH、肉眼可见物和耗氧量外,其他指标均优于地下水Ⅳ类标准。
As a secondary resource,steel slag can be utilized as a resource,but the current utilization rate of steel slag is low,which has caused harm to the ecological environment.Combined with the site environmental survey data of a steel slag recycling enterprise,this paper analyzes the pollution characteristics of the stored steel slag,soil and groundwater in the site,and provides a reference for the site environmental management of the steel enterprise.After testing,the pH of the steel slag samples exceed the standard seriously,all of which are greater than 11.83;the 45 routine testing indicators of soil volatile organic compounds,semi-volatile organic compounds and heavy metals do not exceed the standard;in groundwater,except for pH,visible matter and oxygen consumption,other indicators are better than the standard of groundwater class Ⅳ.
