摘要
为解决地质环境存在的重金属污染问题,探讨了污染现象的形成原因。从不可逆性、广泛性、危害性、隐蔽性等四个方面,阐述了重金属地质污染特点,提出了自然因素与人类活动,是造成重金属地质污染的主要原因。为解决污染问题,提出在农业生产过程中,使用有机肥料代替化学肥料的方式,进行地质污染物的治理,并利用一些特殊植被,吸收土层中的金属元素。通过定期采样与实验室分析的方式,掌握污染源,明确地质环境中重金属物质的来源,实现从源头控制重金属污染物排放;引进工程治理技术与化学治理技术,结合重金属地质污染程度与污染阶段,选用合理的治理技术,进行污染物的处理,优化地质环境。
In order to solve the problem of heavy metal pollution in the geological environment,explore the causes of pollution,this paper expounds the characteristics of Heavy Metal Geological pollution from four aspects:irreversible characteristics,extensive characteristics,great harm and strong concealment;Natural factors and human activities are the main causes of Heavy Metal Geological pollution.In order to solve the pollution problem,it is proposed to use organic fertilizer instead of chemical fertilizer to treat geological pollutants in the process of agricultural production,and use some special vegetation to absorb metal elements in the soil layer.Through regular sampling and laboratory analysis,grasping the pollution source,clarifying the source of heavy metals in the geological environment,the emission of heavy metals from the source is under control.By Introducing engineering treatment technology and chemical treatment technology,combined with the degree and stage of geological pollution of heavy metals,selecting reasonable treatment technology,pollutants were treated and the geological environment was Optimized.
