Printing and dyeing industry wastewater treatment technology: Another feature is the color of dyeing wastewater  high, some up to 4000 times. So one of the important tasks of printing and dyeing wastewater treatment is carried out in Nanjing bleaching treatment recommended cleaning unit, which requires research and selection of efficient decolorizing bacteria, efficient and pro-coagulant decolorization bleaching processes.  printing and dyeing industry, PVA slurry and the use of new additives unit cleaning, making difficult biodegradable organic matter content of a substantial increase in the wastewater. Especially PVA slurry caused CODCr content accounted dyeing wastewater CODCr significant proportion of the total, while the water used in this part of General Microbiology CODCr to degradation. Hence the need for research and screening of microbial degradation of PVA.  In addition, due to the production of intermittent operation unit cleaning company reputation, so there are fluctuations in water quantity and quality; for large-scale use of wastewater unit reduction dyes, sulfur dyes, dyes and other ice cleaning Which is good, relatively poor chemical flocculation. Therefore treatment process to consider these factors have a certain ability to adapt water, water load changes.

Cleaning process is a cleaning media interaction, pollutants, among the workpiece surface, is a complex physical and chemical action process. Cleaning not only the nature of pollutants, the type, shape and degree of adhesion of the relevant physical and chemical properties of the medium and cleaning, cleaning performance, the workpiece material, surface condition, but also with cleaning conditions such as temperature, pressure, and an additional ultrasonic vibration , mechanical force and other factors. Therefore, the choice of scientific and reasonable cleaning process, process analysis must be carried out.
