- 摘要:
- 近年来，二氧化碳排放对环境和人类生活产生的影响越来越显著。目前，从中央到地方都在加紧编制碳达峰行动方案。通过对北京市给水厂紫外线消毒设备的运行数据分析，确认了电力消耗、设备维护维修材料投入及材料运输过程是设备运行环节的碳排放源，且电力消耗在其中占绝大部分。对此，可通过对紫外线消毒设备的运行优化，有效降低碳排放量。此外，开展了套管结垢系数、灯管老化系数试验，并分析了材料投入和运输环节的碳排放情况。分析发现，随着运行时间的增加，灯管的老化系数衰减情况比较明显；而且高负荷运行会导致碳排放量增加，此时应结合设备购置成本等因素，通过更换灯管等方式实现节能减排。
- Abstract:
- In recent years, the growing impact of carbon dioxide emissions on the environment and human life has become increasingly evident. At present, the central and local governments are intensifying efforts to develop carbon peak action plans. It is confirmed that the power consumption, equipment maintenance and repair material input and material transportation process are the carbon emission sources of equipment operation, with electricity consumption representing the majority. Analyzing operational data from ultraviolet （UV） disinfection equipment at Beijing Waterworks confirms this. Optimizing the operation of UV disinfection equipment offers an effective means to reduce carbon emissions. Furthermore, this study was conducted to investigate the scaling coefficient, lamp aging coefficient, following an analysis of carbon emissions related to material input and transportation. It was observed that the aging coefficient of lamp attenuation becomes more pronounced with the increase of operating time. Moreover, operating at high loads correlates with higher carbon emissions. Therefore, decisions regarding lamp replacement should consider factors such as equipment purchase costs, prioritizing energy efficiency and consumption reduction under current circumstances.
