The considerable demand for dyes worldwide has triggered a surge in their production globally. The extensive application of dyes and inefficient dyeing processes has elevated the risk of environmental pollution. The effluents from dying industries contain toxic compounds that are dreadful to both the environment and living beings. Besides, conventional effluent treatment processes have proved ineffective in clearing the dye from the effluent. The sole way of tackling this problem would be by applying a more rational approach that would be sustainable and efficient. After a thorough study of the literature, we are convinced to say that cyanophyceae and algae could serve as one of the promising biodecolorizing agents substituting most other biosorbents used in conventional biological effluent treatment technology. To evidence this we compiled data from the literature, wherein, various algal biomasses capable of decolorizing dye effluents have been examined. This paper also gives comprehensive facts on the mechanism of decolorization, pretreatment, influencing factors, and toxicity of treated products.

藻类和蓝藻生物质作为潜在的染料生物脱色材料：综述

全球对染料的巨大需求引发了全球染料产量的激增。染料的广泛应用和低效的染色工艺增加了环境污染的风险。死亡工业的废水含有对环境和生物都可怕的有毒化合物。此外，传统的污水处理工艺已证明无法有效清除污水中的染料。解决这个问题的唯一方法是采用更合理、可持续和有效的方法。经过对文献的深入研究，我们确信蓝藻和藻类可以作为一种有前途的生物脱色剂，替代传统生物污水处理技术中使用的大多数其他生物吸附剂。为了证明这一点，我们从文献中汇编了数据，其中，已经检查了能够使染料流出物脱色的各种藻类生物质。本文还对处理产品的脱色机理、预处理、影响因素和毒性等方面进行了全面的阐述。
