Abstract

The invention provides a method for treating phenolic waste water. The method comprises the following steps: S1, introducing chlorine dioxide into phenolic waste water and fully mixing chlorine dioxide with phenolic waste water; S2, enabling the phenolic waste water treated in the S1 to flow into a reaction tower filled with an active carbon-loaded nanoscale titanium dioxide catalyst; and S3, introducing oxygen into the reaction tower, and carrying out phenol degradation under irradiation of ultraviolet lights. According to the method for treating phenolic waste water provided by the invention, chlorine dioxide and the active carbon-loaded nanoscale titanium dioxide catalyst are compounded in use to generate a synergistic effect, so that the phenol degradation effect is good. Moreover, during chemical degradation, heating and pressurizing are not needed, the reaction condition is mild, the concentration of chlorine dioxide in reaction is reduced and the treatment safety is further enhanced.

Description

technical field

[0001] The invention relates to a method for treating waste water, in particular to a method for treating phenol waste water.

[0002] Background technique

[0003] Phenol is a raw material and intermediate produced in industries such as papermaking, coking, oil refining, plastics, pesticides, and pharmaceutical synthesis. Phenol-containing wastewater is very harmful to humans. Phenol has a significant corrosive effect on any tissue of the human body, and can invade the human body through mucous membranes, skin contact, inhalation and ingestion. After contact with the eyes, it can cause serious damage to the cornea, even blindness; after contact with the skin, it does not cause pain, but the exposed part initially appears white, if it is not washed away quickly, it can cause severe burns and systemic poisoning; after inhalation, it can cause headaches , dizziness, fatigue, blurred vision, pulmonary edema, etc. After ingestion, it may cause digestive tract ...
