Abstract

A treatment device for low-temperature concentration of heavy metal wastewater relates to the technical field of wastewater treatment and comprises a plurality of evaporation boxes which are mutually fixed and stacked in the vertical direction, and each evaporation box is internally provided with an air pressure adjusting assembly capable of adjusting the air pressure in the evaporation box. A raw water assembly used for supplying heavy metal waste water to the evaporation box is arranged on one side of the evaporation box, the evaporation box heats and evaporates the heavy metal waste water to form evaporation condensate water, and a water collecting assembly used for collecting the evaporation condensate water is arranged on the other side of the evaporation box. And the evaporation capacity is increased by utilizing the depressurization characteristic, and the use energy consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a treatment device for low-temperature concentration of heavy metal wastewater. Background technique [0002] At present, with the development of society, the rapid expansion and development of the manufacturing industry has led to the rapid development of the economy, which is accompanied by the problem of factory wastewater discharge. Industrial wastewater contains a large amount of salt and acid. If it is not treated or treated It is easy to pollute the environment if it is not good, and the existing sewage treatment equipment generally discharges after simple electrolysis treatment, and the acid dissolved in the brine cannot be separated by electrolysis, so the wastewater that is not thoroughly treated will not only pollute the environment, but also Moreover, it will have a certain impact on human health, and the policies introduced now have higher and higher emi...
