Problems solved by technology

[0002] Dichloronicotinic acid is an important pharmaceutical intermediate, which can be used to synthesize 2-alkoxypyridine, etc., and can also be used to synthesize some antibiotics. Because of its wide range of biochemical effects, it has aroused widespread interest. Nicotinic acid is an important pharmaceutical and pesticide intermediate with a wide range of uses. It can be used to manufacture nicotinic acid, nicotinic acid, nicosulfuron, diflufenamide, etc. In response to environmental protection requirements, 2-chloronicotinic acid products The production wastewater needs to meet the national standard discharge requirements. However, the electrolytic oxidation industrial wastewater treatment catalyst and its preparation method in the traditional process have the disadvantages of high catalyst cost, high equipment investment, low activity and short service life, low work efficiency and high treatment cost.

Abstract

The invention discloses a wastewater degradation device for dichloronicotinic acid production, which comprises a first tank, a second tank, a base plate, a photocatalytic chamber, and a COD (chemicaloxygen demand) detector, casters are mounted at the four corners of the bottom end of the base plate, the first tank is mounted on one side of the top end of the base plate, the COD detector is mounted on the other side of the top end of the base plate, the second tank is fixed at the middle position of the top end of the base plate, a top cover is mounted on the top end of the first tank, a waterinlet is arranged at the middle position of the top end of the top cover, a plurality of layers of filter screens are mounted on the top end in the first tank, and a temperature sensor is fixed on one side, which is away from the second tank, in the first tank under the layers of filter screens. According to the invention, by mounting the layers of filter screens, production wastewater can be filtered stage by stage, so that solid impurities of the wastewater can be intercepted by the filter screens, and thereby the impurities are prevented from blocking a pipeline.
