Magnetic recovery and sewage treatment method

The invention relates to a recovery and sewage treatment method, belongs to the technical field of sewage treatment, and in particular, relates to a magnetic recovery and sewage treatment method including the steps: sewage is uniformly distributed on a belt slope surface having the back face provided with a magnetic field region, and magnetic seeds falling off from a belt due to gravity are recovered by using a magnetic seed recovery region arranged below the bottom of a slope top. Therefore, the device, the method and the system adopt the multiple recovery technologies such as brush rolling, spraying and the like, have the advantages of high magnetic seed separation, recovery and utilization rate and large sewage treatment amount; a plate structure is adopted, and the occupied space is small. 本发明涉及种回收及污水处理方法，属于污水处理技术领域，具体涉及种磁回收及污水处理方法。包括：将污水均匀布置于个背面设置有磁场区域的皮带坡面上，利用坡顶底部下方设置的磁种回收区域将因重力而从皮带上脱落的磁种回收。因此，该装置、方法及系统采用滚动毛刷、喷淋等多重回收技术，磁种分离回收利用率高，并且污水处理量大；采用板式结构，占用空间小。
