Technical Field

[0001] The utility model relates to the technical field of wastewater treatment devices, in particular to a phenolic wastewater pretreatment device. Background Technique

[0002] Enterprise waste gas is a major pollution source, and its treatment has always troubled production enterprises. Especially with the development of society, the country and people have paid more and more attention to environmental pollution.

[0003] When many thermal insulation materials are shaped, a large amount of phenolic resin needs to be sprayed. During the production process of heating and curing for shaping, a large amount of waste gas will be generated. The waste gas contains a small amount of pollutants such as free phenol, free aldehyde and particulate matter. After filtration, it is removed by a wet electrostatic precipitator. During the operation of the wet electrostatic precipitator, a large amount of spray circulating water and off-line flushing water are required. Slowly, the concentration of organic substances such as phenol, aldehyde and resin in the water will become higher and higher. Although the existing wastewater treatment devices for thermal insulation material production can preliminarily treat the generated wastewater, the wastewater treatment efficiency is low, seriously affecting the production efficiency of the equipment. At the same time, it is not convenient to recycle water resources, and it also increases the company's production cost and causes waste of resources. Content of the Utility Model
