Review Paper


Coal gasification wastewater (CGW) contains a large number of toxic and refractory compounds, such as phenolic compounds and polycyclic and heterocyclic aromatic compounds. These toxic and refractory compounds are difficult to degrade if biological methods are the only ones used. In recent years, several novel biological coupling processes are used to treat CGW. In the study, this review attempts to offer a comprehensive summary regarding the biological coupling treatment technologies of CGW, including conventional biological processing arts, the combination of adsorption and biotechnology, biological enhancement technologies, co-metabolism technologies and the combination of advanced oxidation and biotechnology. Meanwhile, the treatment efficiency of different biological coupling processes was compared with each other. Co-metabolism and advanced oxidation with biotechnology are both highly effective and promising technologies for degrading toxic and refractory compounds. More research should be conducted on these two aspects in the future.
