  • 摘要: 利用北京某污水处理厂监测数据,建立了该厂的TSS和COD质量平衡模型。利用质量平衡校验污水厂监测数据,结果表明该厂初沉池、生物处理单元和污泥脱水单元TSS平衡误差分别为20.7%、19.3%和5.8%,全厂COD平衡误差为-3.8%,平衡准确性较好。通过与奥地利Strass污水处理厂的COD质量平衡数据进行比较,发现两者的差异主要在于:Strass污水处理厂通过一级处理去除了60.7%的进水COD,而北京某污水厂去除46.0%;Strass污水厂进水COD有35.9%转化为了CH4,而北京某厂为8.5%;Strass污水厂进水COD负荷的21.8%在生物反应池中通过碳氧化和反硝化转化为了CO2,而北京某污水厂为37.3%。COD质量平衡的差异是导致两厂曝气电耗和沼气产电差异的重要原因。以北京某厂COD质量平衡优化为视角,提出污水厂节能降耗的建议。
    Abstract: Based on the monitoring data of a wastewater treatment plant (WWTP) in Beijing, TSS and COD mass-balance models were established. Data from this plant were validated using TSS and COD mass-balance models. The results showed that the TSS mass balance errors of the primary settling tank, biological treatment unit, and sludge-dewatering unit were 20.7%, 19.3%, and 5.8%, respectively. The plant-wide COD mass balance error was -3.8%. By comparing the COD mass distribution with that of the Strass wastewater treatment plant in Austria, differences between the two plants were identified. At the Strass WWTP, 60.7% of the influent COD was removed through primary treatment, while at the Beijing WWTP, it was 46.0%. Regarding influent COD, 35.9% was converted into CH4 at the Strass WWTP, but 8.5% at the Beijing WWTP. For conversion of influent COD into CO2 by carbon oxidation and denitrification processes, the Strass WWTP converted 21.8%, while it was 37.3% at the Beijing WWTP. Differences in the COD mass balance resulted in variations of aeration-energy consumption and biogas-energy generation between these two plants. Measurements to improve and optimize the energy efficiency of the Beijing WWTP are proposed in view of its COD mass balance.
