| 中文摘要 |
| 研究了UV/H2O2体系降解对氯苯酚废水的过程及动力学结果表明,反应降解速率与双氧水加入量、污染物初始浓度及载气种类有关.在双氧水理论投加量一半的情况下,通入氧气或空气,总酚的降解率可达到96%,CODCr去除率接近50%.反应体系加入载气,显著影响污染物的去除率.在本实验中,总酚降解为拟一级反应. |
| 英文摘要 |
| The photodegradation of p-chlorophenol in a hydrogen peroxide-aided photolysis process was investigated. The reaction was influenced by the original concentration of p-chlorophenol and H2O2 addition and carrier gas. With the aid of dioxygen, the removal of phenol and CODCr were reached about 96% and 50% respectively if the original concentration of H2O2 added was only half of stoichiometric calculation. A pseudo-first order kinetic model was adopted to represent the reaction. |
