Abstract

Today, microplastics have become one of the most important environmental concerns. Wastewater treatment plants are a major source of microplastics in the environment. The aim of this study is to track and assess the risk of microplastics in a wastewater treatment plant. Samples were taken from different units of sewage treatment plants in the spring and winter. Microplastics were separated using sieves and density‐based methods. Analysis revealed a higher abundance of microplastics in spring. The highest amount of microplastic removal was in the disinfection and secondary sedimentation units in the winter season. Fragments are the most common shape. Poly Ethylene Terephthalate (PET) polymers were most prevalent. Black was the most common colour. Poly Ethylene (PE), PET and poly Amide (PA) polymers posed the highest risk, according to calculations. One of the most important ways to prevent microplastics from entering water sources is to reduce the consumption of plastic materials, recycle plastic waste and remove microplastics from the wastewater treatment process.
污水处理厂中微塑料的追踪和风险评估
如今,微塑料已成为最重要的环境问题之一。污水处理厂是环境中微塑料的主要来源。本研究旨在跟踪和评估污水处理厂中的微塑料风险。研究人员在春季和冬季从污水处理厂的不同单元采集了样本。使用筛子和基于密度的方法对微塑料进行了分离。分析结果表明,春季的微塑料含量较高。在冬季,消毒和二次沉淀装置中的微塑料去除量最高。碎片是最常见的形状。聚对苯二甲酸乙二酯(PET)聚合物最为常见。黑色是最常见的颜色。根据计算,聚乙烯(PE)、聚对苯二甲酸乙二酯(PET)和聚酰胺(PA)聚合物的风险最高。防止微塑料进入水源的最重要方法之一是减少塑料材料的消耗、回收塑料废物以及在废水处理过程中去除微塑料。

期刊介绍: Water and Environment Journal is an internationally recognised peer reviewed Journal for the dissemination of innovations and solutions focussed on enhancing water management best practice. Water and Environment Journal is available to over 12,000 institutions with a further 7,000 copies physically distributed to the Chartered Institution of Water and Environmental Management (CIWEM) membership, comprised of environment sector professionals based across the value chain (utilities, consultancy, technology suppliers, regulators, government and NGOs). As such, the journal provides a conduit between academics and practitioners. We therefore particularly encourage contributions focussed at the interface between academia and industry, which deliver industrially impactful applied research underpinned by scientific evidence. We are keen to attract papers on a broad range of subjects including: -Water and wastewater treatment for agricultural, municipal and industrial applications -Sludge treatment including processing, storage and management -Water recycling -Urban and stormwater management -Integrated water management strategies -Water infrastructure and distribution -Climate change mitigation including management of impacts on agriculture, urban areas and infrastructure
