摘要
烟气中的汞污染是燃煤电厂污染源之一,将烟气中的Hg0氧化脱除是脱汞的重要思路。采用光化学鼓泡反应器研究UV/H2O2高级氧化工艺脱汞过程,结果表明,增加UV的功率可以提高Hg0去除率;随着H2O2浓度提高,Hg0去除率先上升后趋于下降;随着Hg0初始浓度提高,Hg0去除率呈下降趋势;而Hg0去除率与溶液体积成正比。该UV/H2O2高级氧化工艺可为燃煤电厂烟气脱汞提供新思路。
Mercury pollution in flue gas is one of the pollution sources of coal-fired power plants.Oxidation of Hg0 in flue gas is an important idea for mercury removal.In this paper,the photochemical bubbling reactor was used to study the mercury removal process of UV/H2O2 advanced oxidation process.The results showed that increasing UV power could increase Hg0 removal rate;The removal rate of Hg0 increased with H2O2 concentration increasing at first and then decreased;With the increase of Hg0 initial concentration,the removal rate of Hg0 showed a downward trend;The removal rate of Hg0 was proportional to the volume of solution.Therefore,the process can provide a new idea for mercury removal from coal-fired power plants.
