At present, in the metallurgical industry, in order to improve the recovery rate of valuable metals in precious liquid, reduce the secondary pollution of harmful substances, and realize the filtration and washing treatment of neutralization slag, acid leaching slag, anode mud and other environmental protection standards, filter press and other filtration equipment are needed to filter and wash these materials, so as to achieve the purpose of metal recovery and environmental protection. It can deal with: the lime neutralization of the fuel plant sewage, chlor-alkali plant brine section discharge salt mud, etc., the sodium tripolyphosphate, sodium hyposulfite (common name insurance powder), polyaluminum chloride and other solids extracted from the wastewater.
