| 摘 要： | 以典型厨余垃圾厌氧消化工程为研究对象，使用碳氮平衡全流程模型计算，分析比较了碳氮物质流模型计算结果与采样实测数据；通过碳氮在固液气三相的全流程分配，评价工程实际运行效能.结果表明，实测数据与模拟结果比较，显示碳氮物质流在厌氧产气部分拟合效果较好（拟合优度0.88），但在固液分离组件环节存在显著缺陷.通过优化消化液含固率（TS）与固液分离分配比的关系，改进了模型的固液分离组件，从而提高了沼液和沼渣含固率的模拟效果，拟合优度分别提高至0.97和0.82；通过嵌入实际产气程度（RBMP），提出并应用了一种基于碳氮平衡模型的评估方法，可判别厌氧消化反应器运行状况.

| Abstract: | A typical AD plant for kitchen waste was taken as a case to evaluate carbon and nitrogen flow using the carbon and nitrogen balance model, and the operation performance was evaluated through the distribution of carbon and nitrogen in solid, liquid and gas phases. The results showed that the carbon and nitrogen material flow can fit well with the results of biogas production (goodness of fit was 0.88). The modified solid-liquid separation unit in the model significantly improves the simulation results of solid content (TS) of solid digestate and liquid digestate (goodness of fit increased to 0.97 and 0.82, respectively). Clearly, the carbon and nitrogen balance model-assisted approach, integrated with the actual gas production index (RBMP), is suitable for evaluating the operating efficiency. |
