Electrically enhanced internal anaerobic zero-valent iron reactor

Abstract

一种电增强内置厌氧零价铁反应器,其属于水处理技术领域。在厌氧反应器内部放置两枚石墨电极,石墨电极通过导线连接至外置直流稳压电源,刺激微生物的生长,同时,石墨电极的氧化还原过程增强偶氮染料的还原脱色。将石墨电极设置于厌氧内置生物零价铁反应器内,通过外加微电压调控铁的溶出,增强反应器对酸化的缓冲能力。外加电源与零价铁的耦合还可以加速污泥颗粒化,并有效提高对有机物的分解能力,实现厌氧反应器的快速启动和高效运行。小试实验表明,外加微电压后,可在41天内实现厌氧反应器的快速启动和污泥颗粒化,具有较强的抗冲击能力。
The invention discloses an electrically enhanced internal anaerobic zero-valent iron reactor, belonging to the technical field of water treatment. Two graphite electrodes are arranged inside an anaerobic reactor and connected with an external direct current regulated power supply through a wire to simulate growth of microorganisms; meanwhile, the oxidation reduction process of the graphite electrodes also strengthens reductive decoloration of azo dyes. The graphite electrodes are arranged in the anaerobic internal biological zero-valent iron reactor, dissolution of iron is regulated by applying micro-voltage, and the buffer capacity of the reactor to acidification is strengthened. Coupling of an external power supply and zero-valent iron can also accelerate sludge granulation, efficiently enhance the decomposition capacity to organic compounds and realize rapid starting and high-efficiency running of the anaerobic reactor. A bench scale experiment shows that after the micro-voltage is applied, the rapid starting and the sludge granulation of the anaerobic reactor can be realized within 41 days, and the electrically enhanced internal anaerobic zero-valent iron reactor has stronger shock resistance.
