Problems solved by technology

Since the COD and chroma of water-based ink wastewater are generally very high, there is no direct biochemical treatment condition, and the chroma and COD of the wastewater are difficult even if the method of directly adding water is diluted dozens of times or even hundreds of times or thousands of times. Discharge up to the standard, and at the same time increase the polluted volume of wastewater, the difficulty of treatment and the cost of treatment; the method of incineration, foreign transportation and deep burial also makes the cost of wastewater treatment very high, which is easy to cause secondary pollution, making it unbearable for enterprises

Abstract

The invention belongs to the field of sewage treatment, and more specifically discloses a treatment system and treatment process thereof for ink wastewater in packaging industry. The treatment systemcomprises a wastewater collecting tank (1), a reaction settling tank (2), a sludge tank (3), an aeration tank (4), a pH regulating tank (5), a Fenton oxidation tank (6), a flocculation reaction tank (7), a multi-medium filter (8), a clean water tank (9), and a sludge filter press (10). The treatment process disclosed by the invention overcomes the difficulties of high COD and chromaticity and difficulty in treatment of ink wastewater, so that the quality of the treated water reaches the first-grade discharge standard, and zero discharge of pollution is realized.

Description

technical field [0001] The invention belongs to the field of sewage treatment, and specifically discloses a treatment system and a treatment process for ink waste water in the packaging industry. [0002] technical background [0003] At present, the domestic carton packaging industry generally adopts water-based ink printing technology. In the production process, it is necessary to replace the ink to clean the printing equipment and produce a certain amount of ink wastewater. Since the COD and chroma of water-based ink wastewater are generally very high, there are no direct biochemical treatment conditions, and the chroma and COD of the wastewater are difficult to dilute even if it is diluted dozens of times or even hundreds of times or thousands of times by directly adding water Discharge up to the standard, but also increase the volume of wastewater pollution, treatment difficulty and treatment cost; the method of incineration, foreign transportation and deep burial also m...
