Electroplating wastewater purification device

Abstract

The invention discloses an electroplating wastewater purification device comprising a pretreatment device for pretreating electroplating wastewater; a filter component for purifying water pretreated by a pretreatment device; a first filtering device which is inserted into a first groove body for being mounted in a filter tank; and a second filtering device which is inserted into a second groove body for being mounted in the filter tank. In the purification device provided by the invention, no water flow stress concentration area at the connection positions of the first filter device and the second filter device with the filter tank is present, thereby avoiding the damage of the connection positions of the first filter device and the second filter device with the filter tank when the waterflow rate is higher.

Description

technical field [0001] The invention relates to a water treatment device, in particular to an electroplating sewage purification device. Background technique [0002] Electroplating wastewater is one of the most harmful types of wastewater in real life. Due to the presence of more heavy metals in it, improper treatment of electroplating wastewater can easily cause serious pollution to the environment. For example, electroplating wastewater without proper treatment can easily cause Surface water and soil pollution, thus causing serious harm to humans and other organisms. [0003] In order to treat the electroplating wastewater, there is a filtering method to purify the electroplating wastewater in the prior art, such as the adsorption of heavy metal ions such as antimony ions by means of chitosan and sage, specifically, chitosan, sage, etc. Sage's rolling adsorption brush is intermittently in contact with electroplating wastewater. When heavy metal ions such as antimony ions...

[0002] Electroplating wastewater is one of the most harmful types of wastewater in real life. Due to the presence of more heavy metals in it, improper treatment of electroplating wastewater can easily cause serious pollution to the environment. For example, electroplating wastewater without proper treatment can easily cause Contamination of surface water and soil, thereby causing serious harm to humans and other living things

[0003] In order to treat the electroplating wastewater, there is a filtering method in the prior art to purify the electroplating wastewater, such as using chitosan and sage to absorb heavy metal ions such as antimony ions, specifically, chitosan, sage, etc. Sage's rolling adsorption brush is intermittently in contact with electroplating wastewater. When heavy metal ions such as antimony ions in the wastewater come into contact with the rolling adsorption brush, complexation reactions can occur to capture heavy metal ions; however, this method requires a special The treatment pool is carried out, which makes its structure complex and high in cost; moreover, there is a dead angle of water scour in this way, and its structure is easy to be damaged under the scour of water
