Abstract

The invention discloses a phenolic wastewater biological treatment device. The phenolic wastewater biological treatment device comprises a raw liquid supply tank used for containing phenolic wastewater, a biological reaction component connected with the raw liquid supply tank, a phenol extraction part connected with the biological reaction component, a separation device which is connected with the phenol extraction part and separates out solution and water and a pump component providing flowing power for the solution; the solution separated out by the separation device flows into the biological reaction component. The invention provides a biological treatment device which can continuously and efficiently remove phenol difficult to degrade in industrial wastewater, water is effectively improved, and phenol and an extraction agent are recycled, so that the effects of environment conservation and cost reduction are achieved.

Description

technical field [0001] A waste water treatment field, in particular to a waste water treatment device. Background technique [0002] In recent years, with the acceleration of social development and the improvement of living standards, the development of petrochemical and other industrial structures has changed rapidly, and the pollution of phenol wastewater produced by these industrial structures has become increasingly prominent. It is understood that phenol-containing wastewater mainly comes from coking plants, petrochemical plants, resin plants, insulating material plants, spice plants, plastic plants, etc., and is a raw material and intermediate for papermaking, coking, oil refining, plastics, pesticides, and pharmaceutical synthesis. , which has a stable benzene ring structure and is not easy to degrade, so its wastewater is difficult to treat. Phenol-containing wastewater is very harmful to humans. Phenol is a highly toxic substance, which mainly exists in the produc...
