Treatment system for removing carbamazepine in wastewater

Abstract

The invention discloses a treatment system for removing carbamazepine in wastewater. The treatment system comprises a pH adjusting tank, a coarse screen, an inclined plate sedimentation tank, a biological polymerization reactor, a high-voltage discharging organic rhodium catalytic polymerization reactor, a water purification tank, a weak nitrocotton drying and forming system and the like. The system creatively adopts a technical route of combining a physical manner, a chemical method and microbiological treatment; high energy generated by high-voltage electric arcs is absorbed by N,N-dialkylurea through direct effects of an energy effect and a polymerization catalyzing effect, wherein chemical bonds of an amine radical and a carbonyl group are excited by energy to be at an unstable state, and have bond rupture and are recombined under a surface catalysis effect of dichlorotetracarbonyldirhodium; finally, a polymerization reaction is performed to generate nitrocellulose particles (weak nitrocotton), so that recycling of nitrogen element resources is realized.

Description

technical field [0001] The invention relates to a treatment system for removing carbamazepine in waste water, which belongs to the field of waste water treatment in environmental protection. Background technique [0002] Carbamazepine (also known as carbamazepine) is a commonly used psychotropic drug in clinical practice. It is often used together with other drugs to treat epilepsy, depression and trigeminal neuralgia. After the patient takes it, part of the parent body and its metabolites enter the water environment with the excrement. Therefore, the parent and metabolites of carbamazepine were frequently detected in sewage. The chemical name of carbamazepine is 5H-dibenzo[b,f]azepine-5-carboxamide, which is a nitrogen-containing aromatic compound with a complex chemical structure, and its concentration in wastewater is very low. It is difficult to remove low-concentration carbamazepine by advanced sewage treatment methods. [0003] However, if the residual carbamazepine...

AI Technical Summary

Problems solved by technology

The chemical name of carbamazepine is 5H-dibenzo[b,f]azepine-5-carboxamide, which is a nitrogen-containing aromatic compound with a complex chemical structure, and its concentration in wastewater is very low. The sewage treatment method is difficult to remove low concentration carbamazepine

[0003] However, if the residual carbamazepine in wastewater and the environment cannot be effectively removed, there is a high risk potential threat to human health
