Abstract: Recently, the environmental pollution problems caused by the livestock wastewater have become an important bottleneck to hinder both the healthy development of livestock industry and the construction of ecological civilization. The wastewater treatment technology based on the microalgae cultivation can not only solve the environmental pollution in the livestock industry, but also produce high value-added biomass products, which has attracted more and more attention. This paper briefly summarized the removal mechanism of carbon, nitrogen, phosphorus, antibiotics and heavy metals from livestock wastewater by microalgae. The influence factors for the microalgae technology such as microalgae species, pretreatment of livestock wastewater, cultivation system and conditions were expounded emphatically. The future research should be focused on screening more efficient microalgae species to enrich the germplasm bank of microalgae, developing corresponding compound microalgae-bacteria agents for different types of wastewater, and enhancing the development of downstream products of microalgae to realize the transformation from wastewater to biomass products.
