高级氧化工艺(AOPs)因其在水处理中有效降解持久性有机污染物、病原体和其他污染物而日益受到认可。在众多AOP技术中,等离子体化学因其物理和化学效应的协同作用而脱颖而出,能够高效降解复杂的污染物。本研究着重探讨基于等离子体的AOPs在采出水(PW)处理中的应用,采出水中含有碳氢化合物、重金属和溶解性固体等污染物,这些污染物对传统方法的处理提出了挑战。

介绍

本研究探索了低温等离子体在混合染料废水处理中的应用,考察了不同染料类别之间的相互作用以及活性物质在同步降解中的作用。通过评估放电类型、溶液组成和反应动力学等关键参数,本研究旨在提高基于等离子体的高级氧化工艺在工业废水处理中的可扩展性和效率。

等离子体溶液体系已成为一种极具前景的纳米结构合成方法,具有无需还原剂、实验设计简单以及可在等离子体作用下连续合成等优点。这些体系能够在纳米颗粒形成过程中直接生成还原剂,这使其区别于传统的液相合成方法。

在这项工作中,等离子体处理产生的合成废水可以有效地分解有机污染物并去除石油污染物。

Advanced oxidative processes (AOPs) increasingly are recognized for their efficacy in degrading persistent organic pollutants, pathogens, and other contaminants in water treatment. Among AOP techniques, plasma chemistry stands out because of its synergistic integration of physical and chemical effects, enabling efficient degradation of complex pollutants. This study focuses on applying plasma-based AOPs for the treatment of produced water (PW), which contains contaminants including hydrocarbons, heavy metals, and dissolved solids that challenge conventional methods.

Introduction

This study explores the application of low-temperature plasma for the treatment of mixed-dye effluents, examining the interplay between different dye classes and the role of reactive species in simultaneous degradation. By evaluating key parameters such as discharge type, solution composition, and reaction kinetics, this work aims to enhance the scalability and efficiency of plasma-based AOPs for industrial wastewater treatment.

Plasma-solution systems have emerged as a promising approach for the synthesis of nanostructures, offering advantages such as reductant-free processing, simple experimental design, and continuous synthesis under plasma exposure. These systems enable the direct generation of reducing agents during nanoparticle formation, distinguishing them from conventional liquid-phase methods.

In this work, the plasma treatment of the synthetic wastewater created can effectively break down organic pollutants and remove petroleum contaminants.
