In the world of fast fashion, textile industries are blooming rapidly to meet the consumer's demands. However, vast amounts of wastewater have been constantly produced, and it is becoming a serious environmental problem in the waterways. Although the technology for treating textile wastewater has been well reported and established, more sustainable efforts have taken the attention nowadays. Through the use of living Malaysian Ganoderma lucidum mycelial pellets (GL) and activated dolomite (AD) in the treatment system, the study explores the synergy between biosorption and physisorption as alternative treatment for textile wastewater. In the current work, mixture of GL premixed with AD (50:50; v/v) is used to treat industrial textile wastewater. The morphology, adsorption characteristics, and antibacterial activity of the adsorbents were studied. The mixture of adsorbents is capable of removing colours by 77.8% and reducing chemical oxygen demand (COD) by 75% within 48 h contact. Furthermore, the kinetic and adsorption had been studied and follow the pseudo-first-order kinetic model while both adsorption of Langmuir and Freundlich model was deduced from the treatment. In addition, antimicrobial activities from the treatment potentially reduced 10 × 10 CFU/mL after 48 h. The synergistic treatment by Ganoderma lucidum mycelial pellets and activated dolomite has immense potential in future wastewater treatment technology to obtain cleaner water.
在快时尚的世界里，纺织行业正迅速蓬勃发展以满足消费者需求。然而，大量的废水不断产生，这正成为水道中的一个严重环境问题。尽管处理纺织废水的技术已有充分报道且已确立，但如今更多可持续的努力受到了关注。通过在处理系统中使用活的马来西亚灵芝菌丝体颗粒（GL）和活性白云石（AD），该研究探索了生物吸附和物理吸附之间的协同作用，作为纺织废水的替代处理方法。在当前工作中，将GL与AD预混合（50:50；体积/体积）的混合物用于处理工业纺织废水。研究了吸附剂的形态、吸附特性和抗菌活性。吸附剂混合物在48小时接触时间内能够去除77.8%的颜色并降低75%的化学需氧量（COD）。此外，还研究了动力学和吸附过程，其遵循准一级动力学模型，同时从处理过程中推导出了Langmuir和Freundlich模型的吸附情况。此外，处理后的抗菌活性在48小时后可能将细菌数量减少至10×10 CFU/mL。灵芝菌丝体颗粒和活性白云石的协同处理在未来废水处理技术中具有巨大潜力，有望获得更清洁的水。
