摘要（英）：

The invention discloses a system and a method for preparing a magnesium-zinc ferrite from acid pickling sludge and acid pickling waste liquor and belongs to the field of recycling of hazardous waste.The system comprises a water storage tank, a water pump, a ferrite hydrothermal preparation device, a first charging pump, a second charging pump, an acid storage tank, an alkali storage tank, a discharging pump, a solid-liquid separation and filter-pressing device, a ferrite drying device and a ferrite collecting device, wherein the water storage tank, the acid storage tank and the alkali storagetank are connected with the ferrite hydrothermal preparation device through the water pump, the first charging pump and the second charging pump respectively; a discharge port of the ferrite hydrothermal preparation device is connected with the solid-liquid separation and filter-pressing device through the discharging pump; the solid-liquid separation and filter-pressing device is connected withthe ferrite drying device. The method for preparing the magnesium-zinc ferrite from the acid pickling sludge and the acid pickling waste liquor comprises steps of precursor preparation, hydrothermal preparation of the ferrite, solid-liquid separation and ferrite drying. The acid pickling sludge and the acid pickling waste liquor are co-processed in a recycling manner for preparing the magnesium-zinc ferrite.
