摘要：
Phenolic substances in semi-coking wastewater were converted into phenolic resin by formaldehyde, therefore the resources were utilized. Volatile phenol, COD, ammonia nitrogen and oil in semi-coking wastewater before and after phenolic resin formation were detected to optimize the reaction time, temperature and raw material ratio, eventually the optimal reaction conditions for phenolic resin preparation were determined. Meanwhile, the physicochemical analysis of phenolic resin materials was carried out by XRD and SEM. The results showed that a volume ratio of 1:40 (formaldehyde vs. semi-coking wastewater), a reaction temperature of 90ºC, and a reaction time of 4 hours were the optimum reaction conditions for semi-coking wastewater treated by formaldehyde. © 2024 Peking University.
