用微生物脱除硫化氢恶臭气体的研究

通过以陶粒为填料的生物塔对H2S为代表臭气的实验，研究了生物脱臭系统中H2S负荷，pH值，循环水流量等不同因素对脱除H2S效率的影响和冲击负荷对系统的影响。实验结果表明，pH值控制1～2之间左右，负荷提升其逍度差在100-200kg／m^3左右，循环水量800～1000L／m^3时，脱臭效果好，系统运行稳定。

Study on H2 S-removing by Microoganism

Through experiments on biological towers with ceramic granules as filler and H2S as the stench, the main concern of this thesis is to study how different factors in the biological stench removed system such as the charge of H2S,the pH value,and the circulating water flow,influence the stench-removing efficiency, and how the variation of the charge influences the biological system. The result shows that when the pH value is maintained between 1 and 2, the charge is promoted so that the density deviation is between 100 and 200 kg/m3, and when the circulating water flow remains between 800 and 1 000 L/m3, the stench is removed most differently and the sytem runs smoothly.
