摘　　要：通过Mn_(3)O_(4)催化协同低温等离子体再生废活性炭,考察了放电电压、气体流速、放电时间对甲苯降解率的影响。结果表明,Mn_(3)O_(4)催化协同低温等离子体提高甲苯降解率,在电压为12 kV、气体流速为0.5 L/min,放电时间为30 min时,降解率达到最大,为99.78%。通过对吸附复杂污染物的工业废活性炭的研究,Mn_(3)O_(4)催化协同低温等离子体提高了VOCs的降解率,表明Mn_(3)O_(4)催化协同低温等离子体方法可行。Catalysis by low temperature plasma Mn_(3)O_(4) regenerating activated carbon,the discharge voltage is investigated,the gas flow rate,the influence on the discharge time of toluene degradation rate.The results showed that:Mn_(3)O_(4) photocatalytic degradation rate of toluene to improve the low-temperature plasma,when a voltage of 12 kV,a gas flow rate of 0.5 L/min,the discharge time of 30 min,the maximum degradation rate is 99.78%.Adsorption complex by industrial waste activated carbon contaminants,low-temperature plasma catalysis Mn_(3)O_(4) increased degradation rate of VOCs,low temperature plasma showed Mn_(3)O_(4) catalysis feasible.
