Metal solid waste treatment system

The invention provides a metal solid waste treatment system. The system comprises an ozone generation unit, an aeration unit, a stirring unit and a precipitation unit, wherein the ozone generation unit communicates with the aeration unit through one pipeline; the aeration unit extends into the stirring unit; and the stirring unit communicates with the precipitation unit through one pipeline. The invention further provides a using method of the metal solid waste treatment system. According to the metal solid waste treatment system, the ozone generation unit is adopted, thus the generated ozone is high in concentration and free of pollution, electrode consumption is low, the influence of environment temperature and humidity is avoided, the maintenance cost is low, metal solid waste after ozone oxidation is rapidly precipitated and separated under the action of a flocculating agent, and the waste is changed into wealth. 本发明提供种金属固废的处理系统，包括有臭氧发生单元、曝气单元、搅拌单元和沉淀单元，所述臭氧发生单元经管路与曝气单元相连通，所述曝气单元伸入所述搅拌单元内，所述搅拌单元经管路与沉淀单元相连
