The grinding wastewater treatment equipment project mainly includes three links: wastewater collection, wastewater treatment and wastewater discharge. In terms of wastewater collection, it is necessary to collect and separate the wastewater generated during the grinding process for subsequent treatment. In terms of wastewater treatment, it is necessary to use appropriate treatment equipment, such as physical and chemical treatment equipment, to treat the wastewater and remove pollutants such as suspended matter, organic matter, and heavy metals to meet national emission standards.
