摘要
随着人类生活质量的不断提高,空气质量的管控越来越受到重视。其中以硫化氢(H_(2)S)为代表的恶臭污染物质最为常见,如何高效节能地治理这类污染物成为近年来废气治理行业的研究热点。本研究将H_(2)S浓度较高的废气通入生物滴滤塔中,并通过改变生物营养液的pH值、停留时间等参数调节微生物的生长,探究生物法对目标气体降解的最佳运行参数,以期减少工程应用中的运行成本和设备占地面积。并对进气浓度与去除负荷进行线性拟合,得出具有一定指导意义的关联曲线,以期为小型化生物除臭设备工程应用提供一定的理论支撑。
With the continuous improvement of the quality of human life,the management and control of air quality has received more and more attention.Among them,malodorous pollutants represented by hydrogen sulfide(H_(2)S)are the most common.How to treat such pollutants efficiently and energy-savingly has become a research hotspot in the exhaust gas treatment industry in recent years.In this study,the waste gas with high H_(2)S concentration was passed into the biological trickling filter tower,and the growth of microorganisms was adjusted by changing the pH value of the biological nutrient solution,the residence time and other parameters,and the biological method was explored.The best operating parameters for the degradation of the target gas in order to reduce the operating cost and equipment footprint in engineering applications.The linear fitting of intake air concentration and removal load is carried out,and a correlation curve with certain guiding significance is obtained,in order to provide certain theoretical support for the engineering application of miniaturized biological deodorization equipment.
