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

Embodiment Construction

[0019] like figure 1 A treatment method for removing carbamazepine in wastewater is shown, wherein the wastewater containing carbamazepine enters the pH adjustment pool 1 through the wastewater pipeline, where it is temporarily stored and the pH is adjusted to 6.0-7.0, and the pH adjustment pool 1 The outlet of the coarse grid 2 is connected to the coarse grid 2 through the wastewater pipeline, where the large-diameter solid matter in the wastewater is removed, and the outlet of the coarse grid 2 is connected to the inclined plate sedimentation tank 3 through the wastewater pipeline, where the insoluble substances in the wastewater are further removed, and the inclined plate The outlet of the sedimentation tank 3 is connected to the biopolymerization reactor 4 through the waste water pipeline, and a plurality of biopolymerization films are fixed inside the biopolymerization reactor 4, and highly active Rhodosporidium toruloides and Streptococcus molarii etc. are attached to the...

Abstract

The invention discloses a treatment method for removing carbamazepine in wastewater. Wastewater is sequentially treated in a pH adjustment tank, a coarse screen, an inclined plate sedimentation tank, a biological polymerization reactor, a high-pressure discharge organic rhodium catalyzed polymerization reaction tank, and a clean water tank. The invention creatively uses a technical route combining physical means, chemical method and microbial treatment; through the direct role of energy effects and polymerization catalytic effect, the high energy generated by high-voltage arc is absorbed by N,N-dialkyl urea; the chemical bond of amine radical and carbonyl group is excited by energy and in an unstable state; and the bond ruptures and recombines under the surface catalysis of dichlorotetracarbonyldirhodium, and finally generates polymerization reaction to generate nitrocellulose particulates (weak nitrocotton), so as to achieve the recycling of nitrogen resources.

Description

technical field [0001] The invention relates to a treatment method for removing carbamazepine in waste water, belonging 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 in ...
