Ever-increasing swine wastewater (SW) has become a serious environmental concern. High levels of nutrients and toxic contaminants in SW significantly impact on the ecosystem and public health. On the other hand, swine wastewater is considered as valuable water and nutrient source for microalgae cultivation. The potential for converting the nutrients from SW into valuable biomass and then generating bioenergy from it has drawn increasing attention. For this reason, this review comprehensively discussed the biomass production, SW treatment efficiencies, and bioenergy generation potentials through cultivating microalgae in SW. Microalgae species grow well in SW with large amounts of biomass being produced, despite the impact of various parameters (e.g., nutrients and toxicants levels, cultivation conditions, and bacteria in SW). Pollutants in SW can effectively be removed by harvesting microalgae from SW, and the harvested microalgae biomass elicits high potential for conversion to valuable bioenergy.
不断增加的养猪废水（SW）已成为严重的环境问题。SW 中大量的营养物质和有毒污染物对生态系统和公共健康有重大影响。另一方面，养猪废水被认为是微藻培养的有价值的水和营养源。将 SW 中的养分转化为有价值的生物质，然后从中产生生物能源的潜力引起了越来越多的关注。基于此，本文全面讨论了通过在 SW 中培养微藻来生产生物质、SW 处理效率和生物能源生成潜力。尽管受到各种参数（例如养分和有毒物质水平、培养条件以及 SW 中的细菌）的影响，大量微藻物种在 SW 中生长良好，并产生大量生物质。SW 中的污染物可通过从 SW 中收获微藻而有效去除，并且收获的微藻生物质具有转化为有价值的生物能源的巨大潜力。
