利用生物填充塔处理生活污水厂臭气的研究

The Study of Treatment of Odor Gas Emitted from the Wastewater Plant by the Biofilter

通过对城市生活污水厂逸出臭气所进行的净化治理的中试研究 ,考察了生物填充塔在不同条件下的运行性能 ,探讨了pH的变化对生物填充塔的影响以及填充塔内微生物的分布与恶臭气体去除的关系。结果表明 ,接种脱臭微生物菌群的生物填充塔在合适的工艺条件下能有效地去除生活污水厂臭气中的主要成份—硫化氢 ,同时能耐受一定负荷冲击 ,并且能在酸性条件下稳定运行。

A pilot-scale research on purification of odorous gas emitted from wastewater treatment plant using a biofilter was conducted. The aim of this study is to check on the performance of biofilter running in various conditions and the effect of pH fluctuations on the performance of biofilter. The relation between distribution of microorganism and removal of odorous gases were also discussed here. The experimental results show that the predominant odor-causing gas can be efficiently eliminated by a biofilter inoculated with deodoring microorganism which were isolated previously. Moreover the biofilter had been proved having good tolerance to shocking loads of pollutant and can operate well in the condition of low pH.
