Method for treating amantadine hydrochloride-containing wastewater by using titanium-containing blast furnace slag as photocatalyst

Abstract

The invention belongs to the technical field of sewage treatment and relates to a method of treating amantadine hydrochloride-containing wastewater by using titanium-containing blast furnace slag as a photocatalyst. The method is used to solve high COD and hardly-biodegraded problems of amantadine hydrochloride-containing wastewater. The main technical scheme comprises the following steps of: placing an amantadine hydrochloride-containing wastewater sample with the concentration of 6000mg/L into a photocatalytic oxidation reactor with the volume of 100mL, adjusting the pH value of wastewater to 10-12, using the titanium-containing blast furnace slag as a photocatalyst while its addition concentration is controlled within 0.6-1.2g/L, the ultraviolet radiation time is controlled within 12-16h and the highest water surface distance from the ultraviolet radiation to simulation wastewater is controlled within 1-3cm, reacting and performing timing-sampling. It is proved through tests that titanium-containing blast furnace slag, as a photocatalyst, has a certain effect of treating amantadine hydrochloride-containing wastewater. The amantadine hydrochloride-containing wastewater is effectively degraded and simultaneously a new approach to reutilizing titanium-containing blast furnace slag is also provided so as to achieve the purpose of reutilizing solid waste and treating polluted wastewater.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a method for treating waste water containing amantadine hydrochloride using titanium-containing blast furnace slag as a photocatalyst. Background technique [0002] Amantadine hydrochloride is mainly used for the prevention and early treatment of Asian influenza A virus, the treatment of neurological disorders caused by Parkinson's disease, and the treatment of herpes zoster and postherpetic neuralgia. As it is more and more widely used as a cold medicine, its production capacity has also increased significantly, and the corresponding amantadine hydrochloride wastewater discharge during its production process has also gradually increased. At the same time, due to the characteristics of high COD, difficult biodegradation, and poor biodegradability of amantadine hydrochloride wastewater, it has a serious impact on the environmental water body. Therefore, it is very importa...

Problems solved by technology

At the same time, due to the characteristics of high COD, difficult biodegradation, and poor biodegradability of amantadine hydrochloride wastewater, it has a serious impact on the environmental water body. Therefore, it is very important to study its solution as soon as possible.

[0003] At present, there are very few studies on the treatment of amantadine hydrochloride wastewater at home and abroad. A small number of studies have used crystallization, ozone oxidation technology, fenton technology and other methods to treat amantadi...
