| 摘 要： | 为了降解TNT废水,研究了还原铁屑的用量、pH值、反应时间对超声空化助零价铁降解TNT废水效果的影响。超声空化助零价铁对TNT废水有较好的降解作用,在40 kHz超声频率辐照下,TNT废水初始浓度为150 mg/L、pH为7、还原铁屑用量为3 g、光反应时间为40 min时,TNT去除率达到93.2%,CODCr去除率为79.1%。

| Abstract: | In this paper, uhrasonic cavitation helping zero-valent iron were employed to degrade TNT wastewater： The degradation efficiency was affected by factors such as the dosage of zero-valent iron, the pH value and the reaction time. The test results showed that the method of ultrasonic cavitation helping zero-valent iron could effectively degrade the TNT wastewater. The best removal efficiency of TNT and COI）~ separately reached up to 93.2% and 79.1%, under the conditions as follows： the ultrasonic frequency was 40kHz, the initial concentration of TNT was 150 mg/L, the pit value was 7, the dosage of zero-valent iron was 3.0 g and the reaction time was 40 min. |
