摘要:
以低碳氮比污水为处理对象，采用实验室规模生化反应器试验和数学模拟相结合的方法，开展分步进水SBR工艺生物脱氮效能及工艺优化研究。结果表明，常规SBR法受工艺局限性的影响，对总氮的去除效率偏低。分步进水SBR工艺可高效地去除COD和NH4+-N，对TN的去除效果优于传统SBR工艺，但低于理论去除率。基于STOAT软件构建的数学模型可较好地模拟该工艺的生物脱氮过程。采用数学模拟的方法开展正交试验，确定分步进水SBR工艺的优化运行条件:HRT为9 h，流量分配比为5 ∶3 ∶2，A/O运行时间比为3 ∶2。
Abstract:
Biological denitrification efficiency and process optimization of step-feed SBR process treating low carbon nitrogen ratio sewage were explored by combining lab-scale bioreactor experiments and mathematical simulation. Due to process limitation, the total nitrogen removal efficiency of conventional SBR was low. Step-feed SBR process could remove COD and NH4+-N efficiently, and the removal efficiency of total nitrogen was higher than that of the traditional SBR process, but lower than the theoretical removal value. The biological denitrification process could be properly simulated through the established mathematical model based on STOAT software. Optimized operational conditions were determined by using mathematical simulated orthogonal experiments, which were as follows: HRT of 9 hours, flow distribution ratio of 5 ∶3 ∶2 and anoxic and oxic operational time ratio of 3 ∶2.
