In order to ensure the excellent adsorption performance, this paper choosed lignite activated carbon to study the adsorption performance of typical pollutants phenol, indole and quinoline in coal gasification wastewater, and analyzed its adsorption performance under single matrix and co-substrate conditions. The experimental results showed that among the three kinds of organic substances, lignite activated coke has the strongest adsorption capacity for phenol, while the adsorption capacity for quinoline was relatively low. Under mixed matrix conditions, activated coke has strong adsorption selectivity for phenol and indole.
