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 amantadine in wastewater. Among them, the crystallization method did not decompose the waste water. Pollutants, only amantadine substances are simply precipitated from wastewater. Although ozone and fenton technology can greatly improve the removal efficiency of amantadine hydrochloride wastewater, the initial concentration of wastewater that can be treated is low and the treatment cost is high. Therefore, finding A new process that is both economical and has a certain treatment effect needs to be solved urgently and has great significance

Embodiment Construction
[0013] A method for photocatalytic oxidation treatment of wastewater containing amantadine hydrochloride The specific implementation steps are as follows: respectively place amantadine hydrochloride wastewater (concentrations of 5500 and 6000mg / L) in a photocatalytic oxidation reactor with a volume of 100mL, adjust The pH value of the wastewater is about 10.0, 11.0, the concentration of photocatalyst is controlled at 0.9 g / L, the ultraviolet light time is controlled at 14 hours, and the distance between the ultraviolet light and the highest water surface of the wastewater is controlled at 2cm and 3cm, and the reaction is carried out, and samples are taken regularly. At the end of the reaction, the COD removal rates of amantadine hydrochloride wastewater samples reached 34.52% and 35.12%, respectively.

The invention belongs to the technical field of sewage treatment, and relates to a method for treating amantadine hydrochloride-containing wastewater through photocatalytic oxidation. The invention solves the problem that the amantadine hydrochloride-containing wastewater has high chemical oxygen demand (COD) and is difficultly biologically degraded. The method mainly comprises the following steps of: controlling the initial concentration of an amantadine hydrochloride-containing wastewater sample to be 5,500-6,000mg / L, regulating the pH value of the amantadine hydrochloride-containing wastewater to be about 10-11.0, controlling the adding concentration of a photocatalyst to be about 0.9g / L, controlling the ultraviolet irradiation time to be about 14 hours, and controlling a distance between the ultraviolet irradiation and the highest water surface of the wastewater to be about 2-3cm for reaction. Experiments prove that the method for treating the amantadine hydrochloride-containing wastewater through the photocatalytic oxidation has a certain effect, and is a new way for treating the amantadine hydrochloride-containing wastewater.
Description
technical field [0001] The invention relates to a wastewater treatment method, which is a wastewater treatment method for oxidizing and decomposing refractory organic substances in water by using photocatalytic oxidation technology. 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 important to st...
