当前,出水总氮(TN)稳定达标是我国城镇污水处理厂面临的关键问题。本文基于我国城镇污水处理厂主流工艺——序批式活性污泥工艺(SBR),构建了一种基于可控参数的前馈神经网络(FFNN)出水总氮预测模型。与已有预测模型相比,本模型具备以下两个特点:①采用可控参数(表面气速与缺氧段时长)代替溶解氧作为模型主要输入参数,明显提高模型可用可控性;②采用算法优化的前馈神经网络构建模型,显著提高模型预测精准度。研究结果表明:量化共轭梯度法优化的FFNN模型预测精准,其拟合相关系数(R)明显高于其他相关模型;优化后的FFNN模型可根据进水与关键控制参数实现出水TN精准预测,有望实现城镇污水处理厂总氮稳定去除、系统节能降耗,助力国家“3060”碳目标实现。

MABR exhibits excellent TN removal performance for treating ROC with low C/N ratio. Operating conditions should be properly controlled to achieve optimal TN removal. Denitrifying bacteria and NOB are proved notably inhibited by high salinity stress. The TN removal rate remains over 70% when the NaCl addition amount is below 20 g/L.

根据国家“十二五”氨氮总量控制和典型行业氨氮减排的技术需求,本文选择氮肥工业作为典型,研究共性的工程减排技术决策方法。针对目前国内环境技术评估以定性判断为主,缺乏可操作性强的综合评估方法的状况,提出了以费用效益分析为核心,层次分析+灰色关联度为次重因素的综合评估新方法,确定了该评估方法的数学模型和过程算法,并结合实例进行分析计算和验证。
