  摘要:

  “双碳”方针的告竣，对再生水厂低碳运转提出新的更高的要求。2021年清河第二再生水厂聚焦水区节能降耗与泥区消化产能晋升重点工作，包罗：阐扬流域化运营劣势，经由过程流域水量联调，不变进水负荷；对鼓风机、进水泵等重点耗能装备展开节能优化，保障装备工况与工艺需求实时婚配，实现药耗、电耗双降，水区日均电耗0.353 kW·h/m^{3，较2020年下降20.7%，节电对应CO_{2减排比例26.1%；针对泥质与消化池氨氮负荷转变，经由过程包管初沉泥比例、不变消化负荷、调控进泥含水率等办法，消化系统沼气产量稳步晋升，9月—11月沼气产量均值298 m3/tDS，较1月—8月增幅为21.6%，沼气发电、光伏发电、水源热泵等三项可再生能源操纵项目CO2减排比例近22%。清河第二再生水厂将继续以节能降耗与可再生能源操纵为抓手引领行业绿色低碳转型。}}

  Abstract:

  To achieve the “double carbon” targets, carbon emissions reduction is becoming increasingly important for wastewater reclamation plant. In 2021, Qinghe Ⅱ wastewater reclamation plant (QH Ⅱ) focused on energy conservation in wastewater treatment process and biogas production enhancement in sludge treatment process. It took advantages of watershed operation and stabilized inlet load through joint adjustment of watershed water quantity. Energy efficiency of major energy consuming equipment, such as blowers and inlet pumps, was optimized to ensure the timely matching of equipment working conditions and treatment process requirements. The average daily electricity use in wastewater area was 0.353 kW·h/m^{3, 20.7% lower than that of 2020, and CO_{2emission was reduced by 26.1% corresponding to power saving. In response to changes in sludge characteristics and ammonia nitrogen load of digestion tank, the biogas production was steadily increased by ensuring the proportion of primary sludge, stabilizing the organic loading rate of digester, and regulating the water content of its feed sludge. The average biogas production from September to November was 298 m3/tDS, an increase of 21.6% compared with January to August. The CO2emission reduction rate of three renewable energy projects, including biogas power generation, photovoltaic power generation and water source heat pump system, was nearly 22%. QH Ⅱ will continue to take the lead in the wastewater industry’s green and low?carbon transformation with energy conservation and renewable energy utilization.}}
