Abstract Saline wastewater contains numerous pollutants such as nutrients, heavy metals, micropollutants, and organic pollutants. This kind of wastewater needs to be treated prior to discharging. Compared to other technologies for saline wastewater treatment, the microalgae process is considered to be ‘green’ or environmentally friendly as it generates no secondary pollutants and creates profit. To elucidate the issue, this review investigated the following: (1) the nature of saline wastewater; (2) adaptation of microalgae in saline wastewater; (3) pollutants’ remediation by microalgae in saline wastewater; (4) comparisons with other technologies; and (5) future perspectives. Most importantly, during microalgae process, the saline wastewater is transformed from a waste into a source for biofuel and pigment production. This trend implies to heal the environment, cut remediation expenses and raise revenue.

用于含盐废水处理的微藻：批判性评论

摘要 含盐废水含有多种污染物，如营养物质、重金属、微量污染物和有机污染物。这类废水在排放前需要进行处理。与其他含盐废水处理技术相比，微藻工艺被认为是“绿色”或环保的，因为它不产生二次污染物并创造利润。为了阐明这个问题，本综述调查了以下内容：（1）含盐废水的性质；(2)微藻在含盐废水中的适应性；(3)微藻对含盐废水中污染物的修复；(4) 与其他技术的比较；(5) 未来展望。最重要的是，在微藻过程中，含盐废水从废物转化为生物燃料和色素生产的来源。
