Experimental tests for remedying contaminated soil by home-made microwave equipments
摘要
Abstract
To remedy organochlorine pesticides contaminated soil in a home-made microwave equipment,four magnetrons were installed symmetrically as a microwave generator in home-made microwave equipments.The pot in the microwave cavity for laying up soil was made by SiC which is beneficial for fast heating of the contaminated soil.The results show that dichlorodiphenyltrichloroethane (DDT) in the contaminated soil are efficiently degraded in the equipment.Microwave power and soil mass significantly influence the removal of DDT.For 1 kg soil,77.6% of the total amount of DDTs is removed in 30 min at the microwave power of 4 kW.Compared with conventional heating,the removal of the total amount of DDTs is enhanced about 27.4% in microwave radiation because the heating efficient of microwave radiation is higher than that of conventional heating and chemical bonds can be impaired during microwave radiation.关键词
