The textile industry is one of the largest consumers of water and chemicals, so that each kilogram of textile product requires 100-200 liters of water.Therefore, due to the limited water resources available, having the most pollution among industrial activities and the need to comply with wastewater disposal standards in the environment necessitates wastewater treatment. This study was conducted by review-descriptive method using existing studies. In this article, a review of floating treatment wetland and its application in the wastewater treatment of the textile industry, the key factors affecting the treatment and the combined role of plants and bacteria for maximum purification of contaminated water are presented. Plant tissue in water, roots and rhizomes in sediments play a major role in pollutant treatment. Examining the results of the advantages and disadvantages of different methods in wastewater treatment of the textile industry shows that floating wetland technology is an alternative to traditional and expensive wastewater treatment methods. According to the researches, Phragmites australis is widely used in this technology. Phragmites australis, along with Acinetobacter, Pseudomonas and Rhodococcus, can reduce COD by 92%, BOD by 91%, dye by 86% and heavy metals by 87%.
