Removing SO₂ and NOx released from middle and small-scaled coal-burning boiler is one important strategy for air pollution control. Herein, we first report a novel process on simultaneous eliminating SO₂ and NOx at low temperature, by employing large scale and cheap sources of phosphorus sludge and phosphate rock slurry. The results showed that 100% desulfurization and denitrification efficiency can be obtained, and there exhibited a significant mutual-promoting effect between SO₂ and NOx abatement processes. Based on characterizations and theoretical calculation results, it was found that the active substances produced by the interaction of sulfur and nitrogen species played a significant role in promoting the removal of SO₂ and NOx. Compared with traditional purification technology, this process can achieve simultaneous desulfurization and denitrification with no discharge of secondary pollutants, and can be regarded as a new and economic technology for efficient removal of SO₂ and NOx in industrial scale.

SO2和NOx在黄磷和磷矿浆吸附过程中的相互促进作用

去除中小型燃煤锅炉释放的SO ₂和NOx是大气污染治理的重要策略之一。在此，我们首先报告了一种通过使用大规模廉价来源的磷污泥和磷矿浆在低温下同时去除 SO ₂和 NOx的新工艺。结果表明，脱硫脱硝效率可达100%，SO ₂和NOx减排过程之间呈现出显着的相互促进作用。根据表征和理论计算结果发现，硫和氮物种相互作用产生的活性物质对SO ₂的去除起到了显着的促进作用。和氮氧化物。与传统净化技术相比，该工艺可实现脱硫脱硝同步进行，不排放二次污染物，是一种工业规模高效脱除SO ₂和NOx的新型经济技术。
