摘要

土壤处于陆地生态系统中的无机界和生物界的中心,不仅在本系统内进行着能量和物质[]的循环,而且与水域、大气和生物之间也不断进行物质交换,一旦发生污染,三者之间就会有污染物质的相互传递。作物从土壤中吸收和积累的污染物常通过食物链传递而影响人体健康。土壤污染主要指有机污染和重金属污染,大面积区域污染主要以有机污染为主。针对土壤中有机物污染的现状和污染特点,对土壤中有机污染物的化学修复技术:化学清洗法、超声波氧化法、超临界萃取法进行了研究。
        Soil is at the center of the inorganic and biological world in the terrestrial ecosystem. It not only circulates energy and materials [] in the system, but also constantly exchanges materials with water, atmosphere and organisms. Once pollution occurs, pollutants will be transferred among the three. Pollutants absorbed and accumulated by crops from the soil often pass through the food chain and affect human health. Soil pollution mainly refers to organic pollution and heavy metal pollution, and large area pollution is mainly organic pollution. Aiming at the present situation and pollution characteristics of organic pollutants in soil, the chemical remediation techniques of organic pollutants in soil, such as chemical cleaning method, ultrasonic oxidation method and supercritical extraction method, were studied.
