Printing and dyeing wastewater is an important source of construction wastewater, because it contains a lot of harmful substances such as dyes, modifiers, strong acids and alkalis, it is difficult to solve. The traditional treatment methods of printing and dyeing wastewater generally adopt physicochemical method and biochemical method, but the solution effect is not good, and the recycling cost is high. Therefore, the development of a high efficiency, green environmental protection printing and dyeing wastewater recycling processing technology plays a vital role.

Printing and dyeing wastewater recycling processing technology is an efficient, environmental protection and energy saving, green environmental protection wastewater treatment method. Through the combination of various treatment methods, many pollutants in the wastewater can be effectively removed to ensure the quality of water reuse. At the same time, the process completes the recycling of waste water and improves the utilization efficiency of water resources. Due to the aggravation of water resources pollution and water environment problems, printing and dyeing wastewater recycling processing technology will be more widely used and promoted.
