Problems solved by technology
[0003] The existing heavy metal wastewater treatment uses a magnetic coagulation tank for sludge treatment. The existing magnetic coagulation tank includes a coagulation reaction tank, a magnetic powder reaction tank, a flocculation reaction tank, and a sedimentation tank. The construction period is long, and it cannot be transferred after the construction is completed; and each pool uses a single agitator, the reaction is not sufficient, and the sludge sedimentation efficiency is low

The invention discloses an integrated magnetic coagulation tank, which belongs to the field of wastewater treatment equipment, and is characterized in that the internal space of a tank body of the integrated magnetic coagulation tank is sequentially divided into a coagulation reaction zone, a magnetic powder reaction zone, a flocculation reaction zone and a sedimentation zone by three partition plates along the water inlet direction, and first stirrers are fixed at the tops of the coagulation reaction zone and the magnetic powder reaction zone; a second stirrer is fixed to the top of the flocculation reaction zone, the discharging end of a high-speed shearing machine communicates with the feeding end of a first-stage magnetic separator through a pipeline, the sludge output end of the first-stage magnetic separator communicates with the feeding end of a second-stage magnetic separator through the pipeline, and a sludge header pipe fixedly communicates with a first sludge return pipe anda second sludge return pipe; 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 zone. The integrated magnetic coagulation tank disclosed by the invention is small in occupied area, transferable, sufficient in reaction and high in precipitation efficiency.
Description
technical field [0001] The invention belongs to the field of waste water treatment equipment, in particular to an integrated magnetic coagulation tank. 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 uses a magnetic coagulation tank for sludge treatment. The existing magnetic coagulation tank includes a coagulation reaction tank, a magnetic powder r...
