AI Technical Summary

Technical Problem

Existing technologies present significant challenges in treating wastewater with diphenyl sulfone, and the anaerobic tank is inhibited by high concentrations of diphenyl sulfone, resulting in low sedimentation efficiency and paralysis of the anaerobic treatment system.

Method used

Pretreatment is carried out using a distillation kettle, with stirring by a stirring mechanism, temperature control by a temperature regulator, and organic matter recovery by a condenser. After reducing the pollutant concentration, the pollutants are then treated in a sedimentation tank and an anaerobic tank.

Benefits of technology

It significantly reduces the concentration of pollutants in wastewater, reduces the toxic inhibition of anaerobic microorganisms, and improves the stability and efficiency of biochemical treatment.

Abstract

This invention provides a diphenyl sulfone wastewater treatment device, belonging to the field of chemical production technology. It includes a distillation kettle, a stirring mechanism, a temperature regulator, a condenser, and a recovery water tank. The distillation kettle has a feed port, a discharge port, and a waste discharge port. The stirring mechanism is installed on the distillation kettle and has a stirring shaft located inside the kettle. The temperature regulator is installed on the distillation kettle to regulate the reaction temperature and has a surrounding layer covering the outer wall of the kettle. The condenser has an air inlet and a drain port. The recovery water tank is connected to the drain port and is used to store the cooled product. This diphenyl sulfone wastewater treatment device significantly reduces the concentration of pollutants in wastewater through distillation pretreatment in the distillation kettle. Simultaneously, some organic matter in the wastewater is recovered, reducing the difficulty of wastewater treatment and decreasing the toxicity and inhibitory effect of the wastewater on anaerobic microorganisms, thus preventing the anaerobic treatment system from shutting down.
