Industrial wastewater contains a large number of toxic pollutants, and the total consumption of dyes in the global textile printing and dyeing industry exceeds 587,000 tons per year. Duo to the process of dye production is more complex, the application of processes and materials are more, so many production links will produce a variety of waste, garbage, and the relevant waste dye into the river, lake and sea is up to millions of kilograms. It can be seen that textile printing and dyeing wastewater is the main source of water environmental pollution. If not treated in time, it will not only affect the production efficiency, but also harm the surrounding ecological environment and pose a serious threat to human survival. Scientific and effective intervention of textile industry wastewater and reasonable selection of textile industry wastewater intervention mode are related to the sustainable development of the industry. In recent years, electroflocculation (EC) technology has gradually become a research hotspot due to its advantages of high removal rate, simple operation, small dosage of chemicals, and small impact on the environment, including the intervention of wastewater. This paper will describe the main mechanism of EC and the application status of EC technology is discussed in detail, the limitations and future development trend of this technology are also proposed.
