Patent ID: 8801923

Claim:
A wastewater treatment apparatus that obtains treated water by adding a flocculant and magnetic powder to wastewater accumulated in a tank to thereby generate flocculated magnetic flocs, and recovering the magnetic flocs by means of a magnetic force to thereby remove the magnetic flocs from the wastewater, comprising: a magnetic flocs treatment device which treats the recovered magnetic flocs and which comprises a pump and a magnetic separation portion; wherein the magnetic separation portion has a structure in which fluid piping is arranged at a magnetic field generating portion comprising a magnetic member that has a plurality of electromagnets or permanent magnets mounted in a vicinity of a surface of the magnetic member, and a hollow pipe made of metal that surrounds the member, wherein the fluid piping is wound around the circumference of the hollow pipe, and magnetic powder in the recovered magnetic flocs is recovered by using the pump to pump the recovered magnetic flocs to the fluid piping of the magnetic separation portion, and causing the magnetic powder in the recovered magnetic flocs to attach to the fluid piping by means of a magnetic force of the magnetic field generating portion.
