Magnetic seed recovery system and method suitable for magnetic coagulation clarification equipment

According to the magnetic seed recovery system and method suitable for the magnetic coagulation clarification equipment, sludge containing magnetic seed particles repeatedly enters a magnetic separator for mud-solid separation by utilizing the circulating effect of a sludge stirring pump on sludge in a sludge storage tank, and multiple separation and recovery of the magnetic seed particles in the magnetic separator are achieved; and the recovery rate of the magnetic seed particles is greatly improved. Meanwhile, the sludge shearing machine and the magnetic separator are arranged at the top of the sludge storage tank, and a redesigned magnetic seed particle collecting, recycling and secondary adding system is supplemented, so that the limitation on the mounting position of the magnetic separator and the equipment height of the sludge storage tank due to no pressure of magnetic seed particles and sludge after separation of the magnetic separator can be overcome; and the installation land occupation of the magne
