摘要:- “雙碳”目標的達成，對再生水廠低碳運行提出新的更高的要求。2021年清河第二再生水廠聚焦水區節能降耗與泥區消化產能提升重點工作，包括：發揮流域化運營優勢，通過流域水量聯調，穩定進水負荷；對鼓風機、進水泵等重點耗能設備開展節能優化，保障設備工況與工藝需求及時匹配，實現藥耗、電耗雙降，水區日均電耗0.353 kW·h/m3，較2020年降低20.7%，節電對應CO2減排比例26.1%；針對泥質與消化池氨氮負荷變化，通過保證初沉泥比例、穩定消化負荷、調控進泥含水率等措施，消化系統沼氣產量穩步提升，9月—11月沼氣產量均值298 m3/tDS，較1月—8月增幅為21.6%，沼氣發電、光伏發電、水源熱泵等三項可再生能源利用項目CO2減排比例近22%。清河第二再生水廠將繼續以節能降耗與可再生能源利用為抓手引領行業綠色低碳轉型。
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/m3, 20.7% lower than that of 2020, and CO2 emission 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 CO2 emission 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.
