Zusammenfassung: | The invention relates to the field of C02F water treatment and recovery, in particular to an environment-friendly treatment method for grinding and polishing wastewater. According to the invention, grinding and polishing wastewater containing impurities such as abrasive paper scraps, silicon carbide particles, alumina particles, diamond powder and the like is used as a treatment raw material, and passes through specific types and quantities of filter tanks and ultrafiltration tanks, and polyacrylamide and polyaluminum ferric sulfate are introduced into a first-stage filter tank; the treated water does not contain impurities such as paper scraps, silicon carbide particles, aluminum oxide particles and diamond powder, meets the laboratory water standard, realizes recycling of wastewater, reduces pollution to the environment, improves the utilization rate of water resources, and accords with the research and development concept of the industrial field.
本发明涉及C02F水处理回收领域,更具体地,本发明提供了研磨抛光下水环保处理方法。本发明以含有砂纸纸屑、碳化硅颗粒、氧化 |
