<p>The present invention relates to a magnetic powder recovery system capable of an advanced treatment method of high-concentration MLSS. According to the present invention, the magnetic powder recovery system applicable to a waste water treatment process of an A2O method for treating waste water comprises: a storage tank having waste water introduced thereinto as inflow water; an organism reactor including an anaerobic tank, an anoxic tank, an aeration tank, and a settling tank for discharging a residual sludge. The system of the present invention comprises: a buffer tank for introducing, up to a certain water level, a residual sludge discharged from the settling tank into a housing having an inlet formed on one side and an outlet formed on the other side; a magnetic powder recovery apparatus for separating the magnetic powder from the residual sludge introduced from the buffer tank, discharging the same, and mixing the separated magnetic powder with the inflow water introduced from the storage tank to generate recycled inflow water; and an agitation apparatus for stirring the recycled inflow water generated from the magnetic powder recovery apparatus, in the housing having the inlet formed on one side and the outlet formed in the other side, and then inputting the same to the anaerobic tank of the organism reactor. Therefore, the magnetic powder recovery system of the present invention can reduce treatment costs by recycling the magnetic powder included in the sludge generated during waste water treatment so as to improve economic efficiency.</p> |
