摘要
为实现污水处理厂的电力独立和净零CO 2排放,采用绩效评估系统(PES)对5个处理能力为15万至20万立方米3天-1的污水处理厂进行了电力自足率和温室气体强度评估。在电力独立性方面,对节能与能源生产相结合的措施进行了评价。在A处理厂实施节能措施后,耗电量降至31840千瓦时日-1(减少约20%),电力自给率提高到83%。此外,当引入能源生产措施时,发电量增加到38800千瓦时天-1(增加约50%),电力自给率为105%,被认为是电力独立。为了促进二氧化碳净零排放,对温室气体强度和抵消率进行了评估。即使在A处理厂,计算出的温室气体强度为0.17 kg m -3,也没有达到净零二氧化碳排放(抵消率为48%)。通过改进焚烧炉的运行方式,可将温室气体强度提高到0.08 kg m -3(补偿率为70%)。针对这两个目标,对电力独立性和温室气体排放进行了评估,并确认了实现设想的污水处理厂的高潜力。
A Study on the Potential Evaluation of Achieving Power Independence and Net Zero CO2 Emission at Sewage Treatment Plant
To achieve power independence and net zero CO 2 emission at sewage treatment plants, a performance evaluation system ( PES ) was used at five sites with a treatment capacity of 150,000 to 200,000 m 3 day -1 , to estimate the power self-sufficiency rate and GHG ( Greenhouse Gas ) intensity. For power independence, the combination of energy saving and energy production measures was evaluated. When the energy saving measures were introduced at Treatment Plant A, the amount of power consumption decreased to 31,840 kWh day -1 ( reduction of about 20% ) , and the power self-sufficiency rate improved to 83%. Moreover, when energy production measures were introduced, the amount of power generation increased to 38,800 kWh day -1 ( increase of about 50% ) , and the power self-sufficiency rate was 105%, which was considered to indicate power independence. To promote net zero CO 2 emission, the GHG intensity and offset rate were evaluated. Even at Treatment Plant A, the GHG intensity was calculated to be 0.17 kg m -3 that net zero CO 2 emission was not reached ( offset rate of 48% ) . By improving the operation of the incinerator, the GHG intensity may be improved to 0.08 kg m -3 ( offset rate of 70% ) . Looking toward the two goals, the power independence and GHG emissions were evaluated, and high potential to realize the envisioned sewage treatment plant was confirmed.
