Abstract

Microfibers (natural, regenerated and synthetic) have become a global pollution problem. The dyeing process in the textile industry is one of the main sources of microfiber pollution, while receiving limited attention. A printing and dyeing wastewater treatment plant in a textile industrial park in China was selected for this study. We systematically investigated the occurrence, release and removal characteristics of microfiber in wastewater treatment plants and assessed their contamination risk. Results showed that the microfiber concentration in the influent of printing and dyeing wastewater was 263.1 ± 46.7 MFs/L, in the effluent it was 55.5 ± 10.2 MFs/L, and in the RO effluent it was 8.9 ± 2.8 MFs/L. Although microfiber removal is not inefficient, wastewater treatment plants still release large quantities of microfiber every day. The FTIR results indicated that cellophane is the most common microfiber in this wastewater plant. This also provides a new direction for subsequent microfiber research. Finally, we evaluated the contamination risk of microfiber using various methods. Our study provides a reference for cleaner production in the textile printing and dyeing industry and a feasible direction for future research on microfiber pollution.

印染废水处理厂微纤维的发生、分布及风险评价

超细纤维（天然、再生和合成）已成为一个全球性的污染问题。纺织工业中的染色过程是微纤维污染的主要来源之一，但人们对其关注有限。本研究选取中国某纺织工业园区的印染废水处理厂为研究对象。系统调查了超细纤维在污水处理厂的发生、释放和去除特性，并对其污染风险进行了评估。结果表明，印染废水进水微纤维浓度为263.1±46.7 MFs/L，出水微纤维浓度为55.5±10.2 MFs/L，反渗透出水微纤维浓度为8.9±2.8 MFs/L。虽然去除超细纤维的效率并不低，但废水处理厂每天仍会释放大量的超细纤维。FTIR结果表明，玻璃纸是该污水处理厂中最常见的超细纤维。这也为后续的超细纤维研究提供了新的方向。最后，我们用不同的方法评估了超细纤维的污染风险。本研究为纺织印染行业的清洁生产提供了参考，也为今后超细纤维污染的研究提供了可行的方向。图形抽象

期刊介绍： Water, Air, & Soil Pollution is an international, interdisciplinary journal on all aspects of pollution and solutions to pollution in the biosphere. This includes chemical, physical and biological processes affecting flora, fauna, water, air and soil in relation to environmental pollution. Because of its scope, the subject areas are diverse and include all aspects of pollution sources, transport, deposition, accumulation, acid precipitation, atmospheric pollution, metals, aquatic pollution including marine pollution and ground water, waste water, pesticides, soil pollution, sewage, sediment pollution, forestry pollution, effects of pollutants on humans, vegetation, fish, aquatic species, micro-organisms, and animals, environmental and molecular toxicology applied to pollution research, biosensors, global and climate change, ecological implications of pollution and pollution models. Water, Air, & Soil Pollution also publishes manuscripts on novel methods used in the study of environmental pollutants, environmental toxicology, environmental biology, novel environmental engineering related to pollution, biodiversity as influenced by pollution, novel environmental biotechnology as applied to pollution (e.g. bioremediation), environmental modelling and biorestoration of polluted environments. Articles should not be submitted that are of local interest only and do not advance international knowledge in environmental pollution and solutions to pollution. Articles that simply replicate known knowledge or techniques while researching a local pollution problem will normally be rejected without review. Submitted articles must have up-to-date references, employ the correct experimental replication and statistical analysis, where needed and contain a significant contribution to new knowledge. The publishing and editorial team sincerely appreciate your cooperation. Water, Air, & Soil Pollution publishes research papers; review articles; mini-reviews; and book reviews.
