Problems solved by technology

For aerobic treatment, if the conventional aerobic activated sludge method is used to directly treat this kind of wastewater with a concentration of more than several thousand, it is difficult to discharge it up to the standard, unless it is diluted with a large amount of wastewater, which will lead to increased infrastructure and operating costs.

Embodiment

[0032] This integrated treatment method has been tested in a pharmaceutical company and achieved ideal results.

[0033] The clindamycin alkaline wastewater was taken from the clindamycin production workshop of an enterprise in Nanyang. The production process of the enterprise's clindamycin hydrochloride is to use lincomycin hydrochloride as the raw material, add the chlorinated agent to make the chlorine group replace the hydroxyl group, after alkalization, hydrolysis, extraction, salt formation, concentration and crystallization The process wastewater is mainly lye absorption wastewater, alkali extraction wastewater, vacuum pump sewage, steam condensation wastewater, equipment cleaning water, ground flushing water, etc. This kind of wastewater has complex components, high concentration of organic matter, refractory and many toxic and harmful substances, and the wastewater is thick yellow and has a strong pungent smell. It belongs to high-concentration organic wastewater that...

Abstract

The invention discloses an integrated treatment process of clindamycin alkaline wastewater and belongs to the technical field of wastewater treatment. The process includes steps of: subjecting the clindamycin alkaline wastewater produced in a certain workshop section to Fe2<2+>/K2S2O8 oxidation pretreatment, and feeding the wastewater into a two-stage separation internal circulation anaerobic reactor and a multi-stage A/O reactor to perform biological treatment. The process integrates advantages of a Fe2<2+>/K2S2O8 oxidation technology, the two-stage separation internal circulation anaerobic reactor and the multi-stage A/O reactor. After treatment, the COD removal rate of the wastewater can be more than 99%, the ammonium-nitrogen removal rate can be more than 95%, and the total nitrogen removal rate can be more than 90%. In addition, a biogas product with economic value can be produced. The integrated process has characteristics of small agent adding amounts, high resistance to impact load, low system running costs, stable running, and the like.

Description

Technical field: [0001] The invention belongs to the technical field of waste water treatment, and in particular relates to a 2+ / K 2 S 2 o 8 The integrated treatment technology of oxidation pretreatment, two-stage separation internal circulation anaerobic reactor and compound A / O is especially suitable for the treatment of clindamycin alkaline wastewater. Background technique: [0002] Clindamycin is a semi-synthetic derivative of lincomycin. Compared with the former, its antibacterial activity is increased by 2 to 8 times. At present, the demand in the international market is increasing year by year, and it has the potential to replace lincomycin. Semi-synthetic antibiotic wastewater not only has the characteristics of complex components of synthetic drug wastewater and many refractory substances, but also contains biological inhibitors such as antibiotics like biopharmaceutical wastewater. Its main characteristics are: complex water quality components; high pollutant c...
