Electroplating sewage filtering device

Abstract

The invention relates to an electroplating sewage filtering device including a secondary electrolytic pond, a filter cylinder, a liquid medicine tank and a controller; the secondary electrolysis pond includes a main electrolytic bath and a reference electrode bath; the filter cylinder includes a centrifugal separation chamber and a filter core separation chamber, the centrifugal separation chamber is internally provided with a centrifugal barrel and a second motor, the centrifugal barrel is internally provided with a separation flocculation net barrel, and the filter core separation chamber is internally provided with a plurality of filter cores. The electroplating sewage filtering device has good sewage treatment effect, has high efficiency, and is beneficial for improving the effects of environmental protection and energy saving.

Description

technical field [0001] The invention relates to an electroplating sewage filtering device, which belongs to the technical field of electroplating equipment. Background technique [0002] The electroplating filter device in the prior art is a device that presses the liquid medicine with impurities into the filter barrel through the pump, and removes the impurities by filtering through the filter element, so as to obtain high-precision clean liquid medicine, and the electroplating wastewater contains a large amount of organic matter , organic matter cannot be treated by chemical methods, because the electroplating wastewater contains a large amount of heavy metals, resulting in biochemical bacteria that cannot survive and cannot degrade organic matter, the wastewater treated by chemical methods has a high COD, macromolecular complexes or chelates, using chemical methods It is impossible to separate the heavy metals from the complexing agent. For this reason, secondary electrol...

[0002] The electroplating filter device in the prior art is a device that presses the liquid medicine with impurities into the filter barrel through the pump, and removes the impurities by filtering through the filter element, so as to obtain a high-precision clean liquid medicine device, and the electroplating wastewater contains a large amount of organic matter , organic matter cannot be treated by chemical methods, because the electroplating wastewater contains a large amount of heavy metals, resulting in biochemical bacteria that cannot survive and cannot degrade organic matter, the wastewater treated by chemical methods has a high COD, macromolecular complexes or chelates, using chemical methods It is impossible to separate the heavy metals from the complexing agent. For this reason, secondary electrolytic treatment is often used. However, a large number of flocs are produced in the electroplating sewage, so that the current electroplating sewage filtration device is easy to cause clogging by ordinary filtration methods, and cannot be well cleaned.
