Solidifying agent, flocculation aid, magnetic powder, the rapid adsorbing contaminant of coagulant forms density height, heavy magnetic flocculation group, after High-rate sedimentation
It is separated by solid-liquid separation, coagulation reaction tank upper layer clear water is pumped into magnetically separating and purifying equipment and carries out purified treatment, it is clear that treated
Water enters clear water reserviors, and treated, and rainwater enters Magneto separate magnetic roller, and the magnetic powder isolated is recovered to coagulation by third suction pump
In reaction tank, the utilization rate of magnetic powder is improved, the rainwater isolated enters deslimer by sludge water pump and carries out desliming.
