摘要
研究了微波辐射条件下,以活性炭为催化剂,过氧化氢为氧化剂氧化处理杀螟硫磷生产废水。考察了微波功率、辐照时间、pH值、活性炭用量、过氧化氢用量对COD去除率的影响,在pH值为2.0、微波功率400W、微波辐照时间5 min、过氧化氢用量0.59 mol/L、活性炭用量120 g/L的条件下,废水COD去除率可达到65.9%,并对反应机理进行了初步探讨。
On the condition of microwave irradiation, the treatment of wastewater from fenitrothion manufacturing process by a catalytic oxidation method with activated carbon as catalyst and H2O2 as oxidant was studied. The effects of MV prower, irradiation time, pH value, dosage of activated carbon and H2O2 on the removal rate of COD were examined, under the condition that pH value was 2.0, MV power was 400 W, irradiation time was 5 min, dosage of H2O2 and activated carbon were 0.59 mol/L, 120 g/L respectively, the removal rate of COD in wastewater reached 65.9%. The reaction mechanism was primarily discussed at the same time.
