采用超声波协同Fenton氧化技术对 H MX 生产废水进行处理,考察了超声波频率及功率、Fenton 试剂的投料量、废水的p H 值、反应初始温度等参数对 H MX生产废水中污染物降解的影响。结果表明,反应初始温度及废水的pH 值对降解结果的影响较大。在超声波频率为45 Hz、功率为5 kW/m3、H2 O2与 Fe2+投料量分别为0.235mol和0.023mol,即n(H2O2)∶n(Fe2+)=10∶1,反应初始温度30℃条件下,100mL HMX废水的COD去除率达到80%以上;在 H2 O2投料量较少时超声波协同效应的优势明显,H2 O2与Fe2+摩尔比越低,超声波协同效应越显著,比单独使用 Fenton 试剂处理的效果好;当 H2 O2与 Fe2+摩尔比高于10∶1时,超声波的协同效应几乎消失。
採用超聲波協同Fenton氧化技術對 H MX 生產廢水進行處理,攷察瞭超聲波頻率及功率、Fenton 試劑的投料量、廢水的p H 值、反應初始溫度等參數對 H MX生產廢水中汙染物降解的影響。結果錶明,反應初始溫度及廢水的pH 值對降解結果的影響較大。在超聲波頻率為45 Hz、功率為5 kW/m3、H2 O2與 Fe2+投料量分彆為0.235mol和0.023mol,即n(H2O2)∶n(Fe2+)=10∶1,反應初始溫度30℃條件下,100mL HMX廢水的COD去除率達到80%以上;在 H2 O2投料量較少時超聲波協同效應的優勢明顯,H2 O2與Fe2+摩爾比越低,超聲波協同效應越顯著,比單獨使用 Fenton 試劑處理的效果好;噹 H2 O2與 Fe2+摩爾比高于10∶1時,超聲波的協同效應幾乎消失。

The HMX processing wastewater from HMX production was treated by Fenton agent combined with ul-trasonic.The effects of frequency of ultrasonic(US),power of US,dosage of Fenton agent,pH value of waste wa-ter,and the initial reaction temperature on COD removal rate were studied.Results show that the initial reaction temperature and pH value brought more effect on degradation.When the frequency and power of ultrasonic are 45Hzand5kW/m3,dosagesofH2O2andFe2+ are0.235moland0.023mol,that′stosayn(H2O2)∶n(Fe2+)= 10∶1 ,the initial reaction temperature at 30℃,the COD removal rate can reach to 80%.The advantage of synergistic effect caused by ultrasonic method is as follows:the lower the molar ratio of n(H2 O2 )to n(Fe2+),the stronger the effect is.When the ratio of n(H2 O2 )and n(Fe2+)was larger than 10∶1 ,the positive synergistic effect would al-most disappear.
