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 pond, a coarse grille, a cantboard settling pond, a biological polymerization reactor, a high-voltage electricity-discharging organic rhodium catalysis and polymerization reaction tank, a clear water pond, a weak nitrocotton drying forming system and the like. According to the treatment system for removing carbamazepine in the wastewater, a technological path in which a physical means, a chemical method and microbiological treatment are combined is creatively adopted, through the direct effect of energy effects and polymerization and catalysis effects, the high energy generated by high-voltage arcs is absorbed by N,N-dialkylurea, chemical bonds of amine groups and carbonyl groups are excited by the energy and in an unsteady state, bond fission and recombination occur under the surface catalysis effect of dichlorotetracarbonyldirhodium, finally a polymerization reaction happens to generate nitrocellulose particles (weak nitrocotton), and thus the recycle utilization of a nitrogen element resource is achieved.

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
