Amantadine wastewater resourceful treatment method

Abstract

The invention provides an amantadine wastewater resourceful treatment method, and belongs to the field of sewage treatment methods. The method comprises the following steps: adjusting the pH value of process wastewater, controlling a certain pH value for carrying out carrier gas extraction and concentration, and directly recycling a concentrated solution to a production and recovery process for treatment; pumping the carrier gas extracted fresh water into a biochemical system, and adopting salt-tolerant anaerobic and salt-tolerant aerobic treatment processes; enabling biochemical effluent to be subjected to flocculation precipitation mud-water separation, concentrating sludge and performing outsourcing treatment, and enabling supernate to be subjected to advanced oxidation (AOP) advanced treatment and discharged after reaching the standard. The process design is carried out on the amantadine production wastewater, the technical problem that amantadine is difficult to treat is solved after the amantadine production wastewater is treated by the technology, and the recycling of the wastewater can be realized.

Description

technical field [0001] The invention relates to the technical field of oily and relatively high COD production wastewater treatment process, in particular to a method for resourceful treatment of amantadine wastewater. Background technique [0002] Amantadine, also known as amantadine and tricyclic amantadine, is an anti-influenza drug widely used in recent years, and is widely used clinically for the prevention and treatment of influenza virus type A infectious diseases. Amination wastewater and bromination wastewater are refractory wastewater generated during the production of amantadine, with high organic content, poor biodegradability, and a large amount of amantadine substances. [0003] Amantadine is a saturated tricyclodecane amino derivative, which is a highly symmetrical and very stable cage hydrocarbon. According to data, the content of amantadine in the influent water of sewage treatment plants reaches 184-538 ng / L, primary treatment can remove 6.7%-17.4% of aman...

AI Technical Summary

Problems solved by technology

[0004] The main problem of the prior art: Amantadine production wastewater contains relatively high concentrations of amantadine and its derivatives, which have strong antibacterial activity, poor biodegradability, and difficult treatment. Enter the natural environment with excess sludge, accumulate in the environment, endanger human health, and have toxic effects on native organisms, aquatic organisms, etc.
