酚醛树脂是工业生产中广泛应用的一类树脂，它是由酚类和醛类在酸和碱催化剂作用下合成的缩聚物。本文所涉及的醋醛树脂是氨催化的苯酚甲醛树脂。在醋醛树脂的生产过程中，间歇地产生少量高浓度的有机废水。据测定，废水CODcr在（104－108）mg/l范围内，挥发酚在（102－105）mg
Phenolic resin is a kind of resin widely used in industrial production. It is a polycondensate synthesized from phenols and aldehydes under acid and base catalysis. The aldehyde resin involved in this paper is ammonia catalyzed phenol formaldehyde resin. In the production of acetaldehyde resin, a small amount of high-concentration organic wastewater is intermittently produced. It was determined that the CODcr of wastewater was in the range of (104-108) mg / l and that of volatile phenol was (102-105) mg
