Abstract

BACKGROUND

The treatment of high-strength industrial wastewater containing high organic load and salinity remains a significant challenge for conventional processes. This study presents an integrated two-stage ultrafiltration (UF) system based on modified polyethersulfone (PES) membranes specifically developed for seasoning wastewater treatment to simultaneously address organic pollutant reduction, biofouling, and partial desalination.

RESULTS

In the first stage, the membrane surface was modified with dopamine (DA), polyethyleneimine (PEI), and silver nanoparticles (AgNPs). An optimal 1:1 DA:PEI ratio yielded a flux recovery ratio of 88%, while the incorporation of AgNPs provided distinct antibacterial activity against Shigella flexneri. Additionally, artificial neural networks (ANNs) accurately modeled flux decline with a high predictive accuracy (R2 = 0.964). The second stage, utilizing a glutaraldehyde-crosslinked PES membrane, achieved 53.12% Ca²⁺ rejection compared to only 6.53% for Na⁺, which was primarily driven by Donnan exclusion. Overall, this integrated two-stage system achieved 92.27% chemical oxygen demand (COD) removal.

CONCLUSION

The proposed integrated two-stage modified UF system demonstrates effective fouling mitigation, robust antibacterial functionality, and successful selective multivalent ion removal. These findings highlight the system's strong potential as an energy-efficient treatment or selective pretreatment process for high-strength, high-salinity industrial effluents. © 2026 Society of Chemical Industry (SCI).

两级改性PES超滤系统强化处理高强度调味废水：有机去除及工艺优化

背景：高有机负荷和高盐度的高强度工业废水的处理仍然是传统工艺面临的重大挑战。本研究提出了一种基于改性聚醚砜（PES）膜的集成两级超滤（UF）系统，该系统专为调味废水处理而开发，可同时解决有机污染物减排、生物污垢和部分脱盐问题。结果第一阶段用多巴胺（DA）、聚乙烯亚胺（PEI）和银纳米粒子（AgNPs）修饰膜表面。最佳的DA:PEI比例为1:1，通量回收率为88%，而AgNPs的掺入对福氏志贺氏菌具有明显的抗菌活性。此外，人工神经网络（ann）准确地模拟了通量下降，预测精度较高（R2 = 0.964）。第二阶段，使用戊二醛交联的PES膜，Ca2+的排异率为53.12%，而Na+的排异率仅为6.53%，这主要是由Donnan排斥引起的。总的来说，这个集成的两级系统实现了92.27%的化学需氧量（COD）去除。结论：该两级改性UF系统具有有效的污垢缓解、强大的抗菌功能和成功的选择性多价离子去除效果。这些发现突出了该系统作为高强度、高盐度工业废水的节能处理或选择性预处理工艺的强大潜力。©2026化学工业学会（SCI）。
