摘要:
北京市的5座以热水解-厌氧消化为核心的污泥处理中心中有4座已投入生产，通过分析改造厂A和新建厂B的污泥处理规模、沼气产量等的实际运行参数，得出了必须设计有效的沼气利用系统，以避免资源的浪费的结论。结合A、B两厂的实际运行参数，对沼气发电、沼气提纯以及沼气拖动鼓风机的沼气利用技术进行工艺技术特点及经济分析对比，确定效率高、灵活性强且收益更好的燃气轮机的沼气发电的方案最佳。分析中发现了A、B两厂消化后所产沼气中的H2S浓度高于设计值，且现况干式脱硫系统运行费用高的问题，为此，将脱硫系统设计优化为运行成本低、运行简单以及抗负荷冲击能力强的生物脱硫系统，并保留现况干式脱硫，以保证沼气利用系统的运行稳定。
Abstract:
Four of the five sludge treatment centers with the core process of thermal hydrolysis-anaerobic digestion have been put into production in Beijing. Based on the analysis of the actual operation parameters such as the actual sludge treatment scale and biogas output of retrofitting plant A and new construction plant B, it was concluded that an effective biogas utilization system must be designed to avoid the waste of resources. Combined with the actual operating parameters of plant A and B, the technological characteristics and economic analysis of biogas power generation, biogas purification and biogas utilization technology of biogas drive blower were compared to determine the best scheme for biogas power generation of gas turbines with high efficiency, flexibility and better income. The analysis showed that the H2S concentration in the biogas produced by the two plants after digestion was found to be higher than the design value, and the current operation cost of dry desulfurization system was high. Therefore, the design of the desulfurization system was optimized to be a biological desulfurization system with low operating cost, simple operation and strong resistance to load shock, and the dry desulfurization of the current situation was retained to ensure the stable operation of the biogas utilization system.
