Problems solved by technology

[0002] As we all know, the printing and dyeing industry is a large discharge of industrial wastewater. Wastewater contains a large amount of harmful substances and cannot be discharged directly. It is often treated by chemical or biological methods, but no matter which method is used, a large amount of waste will be generated during the treatment process How to make sludge harmless and turn it into a resource that can be used has become a problem that plagues the entire industry
