污泥厌氧消化工艺中沼气的利用

The Utilization of Biogas in the Anaerobic Digestion Process of Dludge Treatment

以漳州污水处理厂污泥消化过程中产生的沼气为研究对象。通过实验研究,制定了系统的最佳运行参数,达到设计的产气率、脱硫率等指标。同时,在沼气有效利用过程中,通过三级净化处理,较好地去除了硫化氢等。经过两年的运行观察,认为,该系统整体效果较好,产生了较高的社会和经济效益。

Taking the biogas produced by sludge aerobic digestion in Zhangzhou Wastewater Treatment Plant as the research object, the experiment has determined the optimal result has achieved the designed index such as biogas production rate operation parameters, and the and desulfurization efficiency. Additionally, some toxic gases such as hydrogen sulfide have been removed using three-level purification treatment during the utilization process of biogas. The two years operation has indicated that the system has good overall effect, and has produced high social and economic benefits.
