Abstract

This study investigates a novel method for food waste management by using it as a sustainable replacement for conventional pore-forming agents in ceramic membrane production. The membranes were analyzed using various techniques, including X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FT-IR), thermogravimetric analysis (TGA), and a universal testing machine. The morphologies of the membranes were observed using scan electron microscopy (SEM). The effects of particle size (45–125 μm), pore-forming agent (5–20 wt%), and sintering temperature (900–1150 °C) on the porosity and mechanical strength of the membranes were investigated using the Design of Experiments (DoE) and Response Surface Methodology (RSM). The optimized membrane was evaluated for its performance in filtering industrial textile wastewater. It achieved impressive results, with approximately 98.4 % removal of turbidity and 71.3 % removal of chemical oxygen demand. This research paves the way for optimizing ceramic membrane fabrication using upcycled food waste, promoting sustainability and offering potential solutions for both food waste management and industrial wastewater treatment challenges.

以废治废：在采用 DOE/FFD 设计的陶瓷膜制造过程中，使用可循环利用的厨余作为孔隙形成剂处理纺织废水。

本研究通过在陶瓷膜生产中使用厨余作为传统成孔剂的可持续替代品，探讨了一种新型厨余管理方法。研究人员使用多种技术对膜进行了分析，包括 X 射线衍射 (XRD)、傅立叶变换红外光谱 (FT-IR)、热重分析 (TGA) 和万能试验机。使用扫描电子显微镜（SEM）观察了膜的形态。使用实验设计（DoE）和响应面方法（RSM）研究了粒度（45-125 μm）、成孔剂（5-20 wt%）和烧结温度（900-1150 ℃）对膜的孔隙率和机械强度的影响。对优化后的膜在过滤工业纺织废水方面的性能进行了评估。结果令人印象深刻，浊度去除率约为 98.4%，化学需氧量去除率约为 71.3%。这项研究为利用可回收厨余优化陶瓷膜制造铺平了道路，促进了可持续发展，并为厨余管理和工业废水处理难题提供了潜在的解决方案。
