The wastewater from a phenolic resins plant is treated by urea-phenol-formaldehyde basic co-condensation process.Based on uniform design and regression analysis,the effect of factors such as proportioning,catalyst,temperature and time of reaction on processing results is investigated.The optimum process is gained.After purified,99.8 %of phenol and 99.2 % of formaldehyde in the wastewater can be removed.The output meets the need of biological treatment,and a certain amount of phenolic resins can also be recovered.The optimization method can also be applied to increasing the yield of phenolic resins production
