1. Experimental purpose:
The textile printing and dyeing industry plays an important role in improving and enriching people's material and cultural life. The pollutants in the textile printing and dyeing industrial wastewater are m*nly dirt, salts, oils and fats on textile fibers such as cotton wool, as well as various slurries, dyes, surfactants, additives, acids, alkalis, etc. added during the processing. The amount of textile printing and dyeing industrial wastewater is large and it is one of the serious sources of pollution.
In order to understand the commonly used unit operation technologies in textile printing and dyeing wastewater, master the treatment process composed of these unit operations, and observe the behavior of wastewater, sludge and *r during the treatment process, a small dynamic teaching experimental device is specially made to improve people's understanding.
