Problems solved by technology

[0003] The existing heavy metal wastewater treatment system occupies a large area as a whole, and the construction settings are scattered on site between the treatment pools, the construction period is long, and it cannot be transferred after the construction is completed, and the treatment pools cannot be replaced. They can only be dismantled and rebuilt, which is time-consuming force
In addition, a single agitator is used in the sludge sedimentation process, and the reaction is not sufficient, and the sludge sedimentation efficiency is low

Abstract

The invention discloses a heavy metal wastewater treatment system and a treatment method thereof, and belongs to the field of heavy metal wastewater treatment. According to the heavy metal wastewatertreatment system, an electro-catalytic oxidation tank, a PH regulating tank, a heavy metal trapping tank and a magnetic coagulation tank are detachably fixed in a container; first stirrers are fixed to the top of a coagulation reaction area and the top of a magnetic powder reaction area, a second stirrer is fixed to the top of a flocculation reaction area, a high shearing machine, a first-stage magnetic separator and a second-stage magnetic separator are fixed to the top of a pool body, and the discharging end of the high shearing machine communicates with the feeding end of the first-stage magnetic separator through a pipeline. The sludge output end of the first-stage magnetic separator is communicated with the feeding end of the second-stage magnetic separator through a pipeline, the sludge outlet end of the first sludge return pipe is communicated with the feeding end of the high-speed shearing machine, and the sludge outlet end of the second sludge return pipe is fixedly communicated with the bottom of the magnetic powder reaction area. The heavy metal wastewater treatment system and the treatment method thereof are small in occupied area, transferable, sufficient in reaction and high in precipitation efficiency.

Description

technical field [0001] The invention belongs to the field of heavy metal wastewater treatment, and in particular relates to a heavy metal wastewater treatment system and a treatment method thereof. Background technique [0002] Heavy metal wastewater refers to wastewater containing heavy metals discharged from industrial production processes such as mining and metallurgy, machinery manufacturing, chemical industry, electronics, and instrumentation. Heavy metal wastewater is one of the most serious environmental pollution and one of the most harmful industrial wastewater to humans, and its water quality and quantity are related to the production process. Heavy metals in wastewater generally cannot be decomposed and destroyed, but can only transfer their existing positions and change their physical and chemical forms. [0003] The existing heavy metal wastewater treatment system occupies a large area as a whole, and the construction settings are scattered on site between the ...
