Abstract: The decolorization of engineered bacteria bioaugmentation on dyeing wastewater shows obvious advantages in printing and dyeing wastewater biotreatment. The research is focused on the construction and application of bioaugmentation engineered bacteria. In this article，engineered bacteria construction is summarized in dealing with dyeing wastewater. Gene engineered bacteria possess good effect，but with low success rate，high cost and security risk. Bioaugmentation engineered bacteria refer to the high efficient bacterium strains isolated and domesticated from activated sludge，which can be used to treat printing and dyeing wastewater，and have special degradation function on printing and dyeing wastewater pollutants. A detailed introduction is made to the screening and domestication of individual and mixed engineered bioaugmentation bacteria，together with the augmentation effect of xenobiotics. The optimization and promotion of bioengineered bacteria is prospected. Adding bioengineered bacteria into reactors，achieving the combination of engineered bacteria and treatment process，optimizing treatment process，further strengthening the engineered bacteria and putting it into large-scale use shall be the focus of future work.
