摘要

摘要: 溶液吸收法是解决污水处理厂、垃圾填埋场等场所中颗粒物和H₂S臭气污染的一种有效措施,但吸收剂无法再生循环利用阻碍了吸收法的推广使用。设计了溶液吸收-电芬顿工艺,通过聚吡咯薄膜产生微小气泡的方式吸收污染物,考察了气体流速、功能溶液种类对H₂S和颗粒物的吸收效率并进行了反应动力学分析,研究了电芬顿对硫化物的氧化效果,探究了溶液吸收-电芬顿工艺去除H₂S的重复使用性与吸收氧化机理。结果表明:在空气流速为85 mL/min,功能溶液为Na₂SO₄+FeSO₄的条件下,7 h时H₂S和颗粒物的吸收率分别达到89.5%与92.7%,吸收过程均符合一级动力学模型;电芬顿对S^2-的去除率在60 min内达到96.7%;溶液吸收-电芬顿工艺吸收氧化H₂S气体的最终氧化产物为SO^2-₄,具有良好的自清洁和长期循环稳定性。

Abstract: The solution absorption method is an effective measure to solve the pollution of particulate matter and H₂S odor in sewage treatment plants and landfills. However, the non-recycling of absorbent hindered the promotion and use of adsorption method. In this study, a coupling process of solution absorption and electro-Fenton was designed to absorb pollutants by tiny bubbles generated by polypyrrole film, the effects of gas flow rate and functional solution type on the absorption efficiency of H₂S and particulate matter were investigated and the reaction kinetics was analyzed. Meanwhile, the oxidation effect on sulfide, mechanism of absorption and oxidation, and the reusability of the coupling process of solution absorption, and electro-Fenton was also explored. The results showed that the absorption rates of H₂S and particulate matter could reach 89.5% and 92.7% in 7 hours respectively, under the condition of an air flow rate of 85 mL/min and Na₂SO₄+FeSO₄ as the functional solution, and the absorption processes followed the first-order kinetic model; the maximum removal rate of S^2- by electro-Fenton reached 96.7% in 60 minutes and the final oxidation product was SO^2-₄; the coupling process of solution absorption and electro-Fenton showed ideal characteristic of adsorption, oxidation and cyclic stability, and has a large potential application for odor treatment.
