Gongye shui chuli, 2021 针对当前化学强化除磷自控系统的短板，并结合疫情防控常态化背景下污水厂消毒设施的改造升级，从3个方面开展了对化学强化除磷自控系统的优化试验研究：一是将投药点后移至深度处理滤池与接触消毒池之间；二是用当前可快速在线测定的正磷酸盐(OP)替代总磷(TP)作为自控参数，建立总磷与正磷酸盐的相关关系；三是基于化学除磷效率与投药量之间的半经验关系，建立CEPRM模型算法，以取代PLC控制器传统的PID算法。结果表明，优化后污水厂出水总磷稳定达到《城镇污水处理厂污染物排放标准》(GB 18919—2002)一级A标准，

Gongye shui chuli, 2021 采用Fe3O4与PAC制备磁性-化学沉淀复合试剂MPACl，将其用于处理磷化工企业高含磷模拟生产废水。利用响应曲面法进行分析优化，得到对TP去除率影响大小顺序：MPACl投加量> PAC质量分数> pH。最佳运行条件为：MPACl中PAC占比74.75%，MPACl投加量16.07 g/L，pH=9，TP去除率为97.38%。MPACl除磷机理主要为：MPACl中聚合氯化铝水解并与磷酸根发生化学沉淀作用；磁性絮体对磷酸盐的化学吸附和沉淀网捕作用。

Gongye shui chuli, 2014 有机磷水处理药剂生产废水的可生化性差、成分复杂、总磷浓度高，其总磷主要由有机磷类化合物组成，较难处理。尝试采用一级化学除磷—光电催化氧化—二级化学除磷组合工艺处理该废水。实验结果表明：废水经该组合工艺处理后，出水COD、TP分别可达到50、0.5 mg/L，达到《天津市污水综合排放标准》（DB 12/356—2008）的一级排放标准。一级化学除磷—光电催化氧化—二级化学除磷组合工艺可有效地处理有机磷水处理药剂生产废水。

Gongye shui chuli, 2020 针对污水厂精准自动控制的需求，建立了金属盐投加量与除磷效果之间的化学强化除磷投药量半经验CEPRM模型，并结合4种金属盐（硫酸铁、聚合硫酸铁、硫酸铝和氯化铝）化学强化除磷时的污水厂实际生产数据，进行了模型的非线性拟合。结果表明：4种金属盐的拟合相关度均大于0.9，残差平方和均小于0.01，硫酸铝的拟合效果最佳。同时，基于CEPRM模型特点说明了加药自控系统的设置要求与应用模式。

Dimensional Assembly Engineering of Ce‐MOF Interfaces for Selective Recognition of Phytic Acid
Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Selective molecular recognition is central to chemical sensing yet discriminating structurally similar molecules at complex interfaces remains challenging. Traditional strategies based on tuning size, charge, or binding‐site chemistry often suffer from limited flexibility.
