Biological wastewater treatment using trickle bed reactors is a commonly known and used solution. One of the key elements of the proper operation of the trickle bed bioreactor is the appropriate selection of biofilm support elements. The respective properties of the bioreactor packing media used can influence, among other things, the efficiency of the treatment process. In this study, the possibility of polyester waste material usage for the preparation of the biofilm support elements was tested. The following properties were checked: adsorption capacity, swelling, surface morphology, microbicidal properties, as well as the possibility of their use in biological wastewater treatment. The tested elements did not adsorb copper nor showed microbicidal properties for bacterial strains and as well as fungal strains and . The hydrophilic and rough nature of the element surface was found to provide a friendly support for biofilm formation. The durability of the elements before and after their application in the biological treatment process was confirmed by performing tests such as compressive strength, FTIR analysis, hardness analysis and specific surface area measurement. The research confirmed the applicability of the packing elements based on polyester textile waste to the treatment of textile wastewater. The treatment efficiency of the model wastewater stream was above 90%, while in the case of a stream containing 60% actual industrial wastewater it was above 80%. The proposed solution enables the simultaneous management of textile waste and wastewater treatment, which is consistent with the principles of a circular economy. The selected waste raw material is a cheap and easily available material, and the use of the developed packing elements will reduce the amount of polyester materials ending up in landfills.
使用滴流床反应器进行生物废水处理是一种广为人知且常用的解决方案。滴流床生物反应器正常运行的关键要素之一是生物膜支撑元件的恰当选择。所使用的生物反应器填充介质的各自特性等因素会影响处理过程的效率。在本研究中，测试了使用聚酯废料制备生物膜支撑元件的可能性。检查了以下特性：吸附容量、膨胀性、表面形态、杀菌性能以及它们在生物废水处理中使用的可能性。测试的元件既不吸附铜，对细菌菌株 和 以及真菌菌株 和 也未表现出杀菌性能。发现元件表面的亲水性和粗糙性质为生物膜形成提供了有利支撑。通过进行抗压强度、傅里叶变换红外光谱（FTIR）分析、硬度分析和比表面积测量等测试，证实了元件在生物处理过程前后的耐久性。研究证实了基于聚酯纺织废料的填充元件对纺织废水处理的适用性。模拟废水流的处理效率高于90%，而对于含有60%实际工业废水的水流，处理效率高于80%。所提出的解决方案能够同时处理纺织废料和废水，这与循环经济原则相一致。所选的废料原料是一种廉价且易于获取的材料，使用所开发的填充元件将减少最终进入垃圾填埋场的聚酯材料数量。
