Description

Technical Field

[0001] The utility model relates to the technical field of water treatment equipment, in particular to a heavy metal wastewater resource treatment equipment. Background Art

[0002] Heavy metal wastewater refers to wastewater containing heavy metals discharged during industrial production processes such as mining, machinery manufacturing, chemical industry, electronics, and instrumentation.

The heavy metals in the wastewater generally cannot be decomposed and destroyed, but can only be transferred to another location and transformed into a physical and chemical form. In the treatment of heavy metal resources, chemical precipitation is usually used. The precipitation method is to add an appropriate amount of precipitant so that heavy metal ions react with it to form an insoluble precipitate, which is then removed by solid-liquid separation. In the current treatment device, the use of precipitation makes it difficult to remove the precipitate. In this regard, a heavy metal wastewater resource treatment device is proposed to facilitate the operator to remove the precipitate.
