用微藻修复废水是一个新话题，专注于设计一种具有成本效益且对环境有益的方法。最近评估了多种微藻和细菌财团，以确定它们是否可以净化来自各种来源的污水。系统功效的关键是它能够去除氮（N）和磷（P）等营养物质以及砷（As）、铅（Pb）和铜（Cu）等重金属。这项研究将传统的废水处理系统与基于微藻的系统进行了比较，以处理不同类型的废水。该研究调查了微藻净化废水的潜力。该研究还评估了从受污染水中提取营养物质和重金属的废水参数、方法和科学技术。根据文献，微藻可以从各种流出物中去除 98.7% 到 100% 的氮（N）、磷（P）和重金属。本文最后讨论了使用微藻修复废水的困难。污水中营养物质的消除受生物质生产、渗透能力、温度、pH 值和 O2 浓度的影响。因此，建议进行“试点”研究来调查污染物。

Wastewater treatment by using microalgae: Insights into fate, transport, and associated challenges

The remediation of wastewater with microalgae is a new topic that concentrates on devising a cost-effective and environmentally beneficial method. Multiple microalgae and bacterial consortiums have recently been evaluated to determine if they can purify effluent from various sources. Critical to a system's efficacy is its ability to remove nutrients such as nitrogen (N) and phosphorus (P) and heavy metals such as arsenic (As), lead (Pb), and copper (Cu). This study compared traditional wastewater treatment systems to microalgae-based systems for treating different types of wastewater. The research investigates the potential for microalgae to cleanse wastewater. The research also evaluates wastewater parameters, methods, and scientific techniques for extracting nutrients and heavy metals from polluted water. According to the literature, Microalgae can remove between 98.7% and 100% of nitrogen (N), phosphorous (P), and heavy metals from various effluents. The paper concludes by discussing the difficulties of using microalgae to remediate wastewater. The elimination of nutrients from the effluent is influenced by biomass production, osmotic capacity, temperature, pH, and O2 concentration. Therefore, a “pilot” study is recommended to investigate contaminants.
