摘 要
随着工业化进程的加速，工业废气排放已成为制约可持续发展的关键问题之一。传统物理化学处理方法存在成本高、二次污染等弊端，生物转化法作为一种新兴绿色技术，在废气处理领域展现出独特优势。本研究旨在探索生物转化法在工业废气处理中的应用潜力，以挥发性有机物(VOCs)为主要研究对象，选取典型化工园区废气为样本，构建了基于微生物群落的生物滴滤反应器系统。通过优化反应条件，筛选出对甲苯、二甲苯等VOCs具有高效降解能力的优势菌株，并建立了适宜的运行参数体系。实验结果表明，在最佳条件下，该系统对主要污染物去除率可达90%以上，且运行稳定可靠。与传统方法相比，生物转化法不仅处理效率更高，还具有能耗低、无二次污染等显著优点。本研究首次将特定功能微生物应用于实际工业废气处理场景，实现了从实验室研究到工程应用的关键突破，为工业废气治理提供了新的思路和技术支持，对推动绿色低碳发展具有重要意义。

Abstract
With the acceleration of industrialization, industrial exhaust gas emissions have become one of the key issues constraining sustainable development. Conventional physicochemical treatment methods are plagued by high costs and secondary pollution. As an emerging green technology, biological transformation has shown unique advantages in the field of exhaust gas treatment. This study aims to explore the application potential of biological transformation in industrial exhaust gas treatment, focusing on volatile organic compounds (VOCs) as the primary research subject. A bio-trickling filter reactor system based on microbial communities was constructed using exhaust gas samples from a typical chemical industrial park. By optimizing reaction conditions, dominant strains with high degradation capabilities for VOCs such as toluene and xylene were screened, and an appropriate operational parameter system was established. Experimental results indicate that under optimal conditions, the removal efficiency of major pollutants can exceed 90%, with stable and reliable operation. Compared to traditional methods, biological transformation not only offers higher treatment efficiency but also exhibits significant advantages such as lower energy consumption and no secondary pollution. This study represents the first application of specific functional microorganisms in real-world industrial exhaust gas treatment scenarios, achieving a critical breakthrough from laboratory research to engineering application. It provides new insights and technical support for industrial exhaust gas management, contributing significantly to the promotion of green and low-carbon development.
