摘要:
在多级A/O工艺运行过程中，有效利用原水中的碳源和控制各级污泥浓度对系统节能降耗和出水达标排放至关重要，其中调整进水分配比和外回流比是现场工艺优化最直接的突破点和操作入口。基于污水厂运行的实测数据，应用BioWin软件对北京碧水污水处理厂二级反应阶段进行数值模拟。通过模型搭建、校核（参数修正）、验证进行实际进水水质生化反应模拟。结果表明，当进水分配比为50% ∶30% ∶20%、外回流比（R）为100%时工况最优；经工程验证，在最优工况条件下多级A/O工艺运行稳定，出水水质效果最佳，对COD、TN、NH3-N的平均去除率分别为95%、73%、99%，相比调节前平均去除率分别提高了9%、10%、3%。但受多级A/O工艺自身缺陷性的限制，好缺氧交替难以为除磷菌提供厌氧环境，从而导致除磷效率较低。
Abstract:
During operation of a multi-stage A/O process, effective utilization of carbon sources in raw water and control of sludge concentration of each unit are of great importance to save energy of the system and comply with discharge standard. Among them, adjustment of influent distribution ratio and external reflux ratio are the most direct operational measures of field process optimization. Based on actual operational data of the wastewater treatment plant（WWTP）, BioWin software was applied to simulate the secondary reaction stage of Beijing Bishui WWTP. The biochemical reaction with real influent quality was simulated through model construction, checking (parameter correction) and verification. When the influent distribution ratio was 50% ∶30% ∶20% and the external reflux ratio (R) was 100%, the operational condition was the best. Engineering verification showed that the multistage A/O process was stable and the effluent quality was the best. Average removal efficiencies of COD, TN and NH3-N were 95%, 73% and 99%, respectively, which were 9%, 10% and 3% higher than those before adjustment. However, restricted by defect of the multi-stage A/O process itself, it was difficult to provide an anaerobic environment for phosphorus removal bacteria due to alternate aerobic-anaerobic operation of the process, resulting in low phosphorus removal efficiency.
