摘　　要：通过向两相厌氧反应器产甲烷段添加零价铁,考察零价铁对厌氧产甲烷反应器(R1)处理颜料废水效果的强化作用。与未添加零价铁的传统产甲烷反应器(R2)相比,R1的COD去除率和甲烷产量分别提高了27%和53%。在进水负荷发生变化的情况下,R1的COD去除率仍保持在69%,而传统反应器只有31%.因此,R1具有良好的抗冲击负荷。Zero-valent iron(ZVI) was added to the methanogenic reactor(R1) of a two-stage anaerobic system to enhance anaerobic treatment of pigment wastewater.Compared to the traditional methanogenic reactor without ZVI(R2),COD removal and methane production in R1 were improved by 27% and 53%,respectively.The COD removal in R1 was maintained at 69% under variable influent loads,while it was only 31% in the traditional anaerobic reactor.Therefore,R1 has a good shock load tolerance.
