Problems solved by technology

The main problem is that the simulation system used in the research has a single target substance, which is very different from the actual wastewater system, and it is difficult to directly apply it to the treatment process of industrial wastewater.

Embodiment 1

[0014] Treatment objects: reddish brown adamantane amination wastewater (TOC about 3900mg / L) and light yellow adamantane bromination wastewater (TOC about 820mg / L) produced during the production process of a pharmaceutical factory.

[0015] In a glass open container, add adamantane bromination wastewater dropwise to 300 ml of adamantane amination wastewater, stir magnetically at a speed of 100 rpm, and adjust the pH value of the wastewater to 8. After filtering through a 0.45 micron fiber membrane, take 80ml and place it in a 250ml glass conical flask, add the extractant according to the ratio of the extractant to water at 1:1, the extractant is P 204 and n-octanol mixture, where P 204 The volume content is 60%. At room temperature, magnetic stirring was carried out at a speed of 250 rpm for 15 minutes. Then transfer to a separatory funnel, let stand for 60 minutes, and separate layers. The TOC of the separated wastewater was reduced to 1450mg / L, and the removal rate reache...

Abstract

The invention relates to a method for reducing organic matter in amantadine production wastewater. In particular, the present invention relates to a method for separating organic matter from amantadine production wastewater by solvent extraction. Including adding adamantane bromination wastewater to adamantane amination wastewater to adjust the pH value of the wastewater, filtering out the solids therein, and then preparing an extractant composed of complexing agent + diluent, and treating the filtered wastewater at room temperature Perform a mixed extraction. The method of the invention can significantly reduce the organic matter in the adamantane production wastewater, and realize the purpose of pretreating the amantadine production wastewater.

Description

technical field [0001] The invention relates to a method for reducing organic matter in amantadine production wastewater, which is mainly used for pretreatment of amantadine production wastewater, and belongs to the technical field of industrial production wastewater treatment and environmental protection technology. Background technique [0002] Amantadine, chemically known as Tricyclo[3,3,1,1 (3，7) ] Decane-1-amine, also known as tricyclodecanylamine. It is an antiviral drug, suitable for the prevention or treatment of respiratory tract infection caused by Asian A-II influenza virus, and it is effective for the treatment of Parkinson's disease. [0003] In industrial production, amantadine is chemically synthesized from dicyclopentadiene through hydrogenation, isomerization, bromination and amination. During this synthesis, two main streams of production wastewater are produced: adamantane bromination wastewater and adamantane amination wastewater. The adamantane bromin...
