Embodiment Construction
[0010] The present invention will be described in detail below with reference to the accompanying drawings.
[0011] In the figure: 1. Ozone generator; 2. Gas flow meter; 3. Ozone oxidation contact reactor; 4. Tail gas absorption device; 5. Sampling port.
[0012] Put the amantadine waste water in the ozone oxidation contact reactor, pass through the ozone, and control the ozone inlet flow rate to 0.25m 3 / h, adjust the pH value in the reactor within the range of 6.0 to 8.0, and control the reaction time to react. At the end of the reaction, the COD removal rate of the amantadine wastewater was up to 97%, and the tail gas was absorbed by the KI solution in the tail gas recovery device.
[0013] The present invention utilizes ozone as an oxidant to oxidize amantadine wastewater based on the following theory: the reaction between ozone and pollutants in water mainly passes through two pathways, that is, the direct reaction of ozone and the indirect reaction of hydroxyl radical ...

The invention relates to a method for ozonating amantadine wastewater, which belongs to the technical field of sewage treatment. The invention solves the problems of amantadine wastewater, including high COD and hard biodegradation. The main technical scheme is as follows: an experiment indicates that the concentration of amantadine is related to the concentration of COD within a certain range, an ozone generator is utilized to generate ozone, which is sent into an ozone reactor, the ozone and amantadine water sample sufficiently react in the ozonation contact reactor, the COD in the amantadine wastewater is degraded by controlling reaction conditions, and the change of the content of the amantadine is judged according to the change of the COD value. The design of the technical scheme is reasonable, the COD value in the water sample is greatly reduced, the technological method and the supporting requirement are simple, implementation is easy, and popularization and application are convenient. The invention provides a scientific and effective method for the treatment of amantadine wastewater, and solves the problem that the amantadine wastewater is hardly treated.
Description
technical field [0001] The invention relates to a sewage treatment method, in particular to an oxidation treatment method for oxidative decomposition of refractory substances in water by using ozone. Background technique [0002] Cold is the most common frequently-occurring disease, and the users of cold medicines are the most, and they constitute a huge cold medicine market. One of the main uses of amantadine is as a raw material for colds, and its consumption is increasing sharply. The dosage of amantadine raw materials used in compound anti-cold preparations and single preparations is relatively stable, and the market usage for veterinary medicine is also increasing year by year, which determines that amantadine has a broad application market, and its market usage is also increasing year by year. Make the production of amantadine have stable development. Therefore, there are more and more manufacturers producing amantadine, and the output is also increasing, and more an...
