摘要

本研究评估了改性废棉布生物膜反应器（MWCC-BR）作为一种新型低成本生物膜载体在分散式系统中优化生活污水处理的性能。采用正交实验（OE）设计和主成分分析（PCA）方法，评估了水力停留时间（HRT）、溶解氧（DO）、温度和填充率（FR）等关键操作参数对化学需氧量（COD）、总磷（TP）和铵态氮（NH₄+ -N）去除效率（RE）的影响。主成分分析结果显示，水质特征与处理效果之间存在显著的相关性，COD和TP浓度越高，污染物的降解能力越强。它还为优化系统性能提供了有价值的见解，并为实际应用程序提供了一个健壮的框架。在最佳条件下，MWCC-BR对COD的回收率为96.5 %，对NH₄+ -N的回收率为82.8 %，对TP的回收率为60.1 %。本研究表明，MWCC-BR通过为废水处理、固体废物回收和环境保护提供成本效益高、环境友好的解决方案，具有与可持续发展目标6（清洁水和卫生设施）保持一致的潜力。

Innovative optimization of modified waste cotton cloth biofilm reactor for sustainable domestic wastewater treatment

This study evaluated the performance of a Modified Waste Cotton Cloth Biofilm Reactor (MWCC-BR) as a novel and low-cost biofilm carrier for optimizing domestic wastewater treatment in a decentralized system. The study employed an orthogonal experimental (OE) design and Principal Component Analysis (PCA) to assess the impact of key operational parameters, including hydraulic retention time (HRT), dissolved oxygen (DO), temperature, and filling rate (FR), on the removal efficiencies (RE) of chemical oxygen demand (COD), total phosphorus (TP), and ammonium nitrogen (NH₄⁺-N). The PCA revealed significant correlations between influent characteristics and treatment performance, with higher influent COD and TP concentrations enhancing pollutant degradation. It also provided valuable insights for optimizing system performance and offered a robust framework for real-world applications. Under optimal conditions, MWCC-BR achieved RE of 96.5 % for COD, 82.8 % for NH₄⁺-N, and 60.1 % for TP. This study demonstrates the potential of MWCC-BR to align with Sustainable Development Goal 6 (clean water and sanitation) by providing a cost-effective, environmentally friendly solution for wastewater treatment, solid waste recycling, and environmental protection.
