METHOD FOR HARMLESSNESS-PROCESSING PCBS(POLY CHLORINATED BIPHENYLS) WITH AN OXIDIZER AND ULTRASONIC WAVES WHICH ARE ENVIRONMENT FRIENDLY

摘要

PURPOSE: A method for harmlessness-processing PCBs(Poly Chlorinated Biphenyls) with an oxidizer and ultrasonic waves is provided to easily process wastewater containing the PCBs in a short time at a room temperature.;CONSTITUTION: A method for harmlessness-processing PCBs(Poly Chlorinated Biphenyls) includes a step for adding an oxidizer and a catalyst in wastewater containing the PCBS and a step for irradiating ultrasonic waves. The oxidizer is hydrogen peroxide. The hydrogen peroxide of 0.1g is added in the wastewater 1l. The catalyst is cupric oxide. The ultrasonic wave is irradiated fro 3 ~ 5 hours.;COPYRIGHT KIPO 2010
