Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a treatment device for waste water from phenolic resin production. Background technique [0002] There are two main sources of phenolic resin wastewater, one part is the water produced during the condensation process of phenol and aldehyde, and the other part is about 63% of the water contained in the raw material formaldehyde. Phenolic resin wastewater usually has the following characteristics: (1) complex composition and high chemical oxygen demand; (2) many highly toxic substances; (3) poor biodegradability. If the wastewater with high concentration of phenolic resin is discharged directly without treatment, the impact on the environment will be huge and far-reaching. The degradation and treatment of high-concentration phenolic resin wastewater has attracted widespread attention from various countries. For example, the US National Environmental Protection Age...
