Abstract

The invention discloses a waste discharging treatment system for trimanganese tetraoxide production. The waste discharging treatment system comprises a collecting tank, an oxidizing tank, a filter pressing tank, a precipitating pond and a manganese precipitating tank, wherein a collected wastewater outlet of the collecting tank is communicated with an oxidized wastewater inlet of the oxidizing tank through a pipeline; an oxidized wastewater outlet of the oxidizing tank is communicated with a material inlet of the filter pressing tank through a pipeline; a filtered water outlet of the filter pressing tank is communicated with a liquid inlet pipe of the precipitating pond through the pipeline; a liquid outlet pipe of the precipitating tank is communicated with a clear liquid inlet pipe through a pipeline; a precipitate discharging opening of the manganese precipitating tank is communicated with the material inlet of the filter pressing tank through a pipeline. According to the waste discharging treatment system disclosed by the invention, through twice manganese precipitating, the treatment on manganese ions in manganese-containing wastewater is greatly increased, and the wastewatertreating effect is better; meanwhile, the manganese ions in the wastewater are precipitated for twice and are recycled and reutilized, and the production cost is greatly saved.

Description

technical field [0001] The invention belongs to the technical field of waste water treatment, and in particular relates to a waste treatment system for manganese tetraoxide production. Background technique [0002] At present, 90% of manganese tetraoxide is prepared by the electrolytic metal manganese suspension oxidation method, and 5-8 tons of industrial wastewater will be produced in the production process of each ton of manganese tetraoxide, which contains a large amount of manganese, calcium, Magnesium, sodium, chlorine, silicon and other elements, if these elements are directly discharged along with the wastewater, it is not only a waste of water resources and manganese, but also a kind of pollution to the environment. The existing treatment method is to treat the wastewater by chemical oxidation, so that the manganese element in the wastewater reacts with oxygen to form a precipitate (manganese oxide), and then the solid-liquid separation realizes the recovery of the ...
