摘要: 用臭氧对神经性化学战剂的模拟剂氯磷酸二苯酯（DPCP）进行洗消，试验考察了初始酸度、O2流量、放电功率、放电室压力、反应温度、初始浓度和O3流量等因素对DPCP降解率的影响。碱性条件下DPCP降解率高于酸性条件下的降解率；反应温度、O3流量、放电功率的增加，DPCP降解率上升；初始浓度增加，DPCP降解率下降；氧气流量和放电室压力增加，DPCP降解率先上升，后下降。在最佳反应条件下，50 mg/L的DPCP处理16 min降解率达到98%，矿化率40.1%。Abstract: Diphenyl chlorophosphate (DPCP), the stimulant of nerve chemical warfare agent, was decontaminated by ozone. Degradation efficiency was evaluated by concentration of DPCP after and before reaction. Acidity, oxygen flux, discharge power, pressure of discharge chamber, temperature, initial concentration and ozone flux was investigated, respectively. Experiments show that degradation efficiency of DPCP in alkaline solution was apparently higher than it in acid solution. Degradation efficiency of DPCP increased with the increase of temperature, O3 flux and discharge power, and decreased with increase of initial concentration of DPCP. Degradation efficiency of DPCP increased firstly, then decreased with increase of ozone flux and pressure of discharge chamber. Aqueous solution contained DPCP of 50 mg/L was decontaminated by ozone for 16 min with the optimal parameters selected from every influencing factor. Degradation efficiency of DPCP was 98%. Mineralization efficiency was 40.1%.
