An environmental protection separation and purification device for industrial wastewater heavy metal ion electrolysis filtration

Abstract

The invention discloses an environment-friendly separation and purification device for heavy metal ion electrolytic filtration of industrial wastewater. The environment-friendly separation and purification device comprises an electrolysis tank, wherein a supporting plate is fixedly connected to the right upper end of the electrolysis tank; an electrolytic anode is connected to the supporting plate in a sleeving manner; a support base is fixedly connected to the left upper end of the electrolysis tank; an electrolytic cathode is connected to the support base in a sleeving manner; a valve is mounted at the left lower end of the electrolysis tank through threads; a filtering device is mounted at the left end of the electrolysis tank through screws; and a pipeline is mounted at the lower end of the filtering device through screws. According to the environment-friendly separation and purification device for heavy metal ion electrolytic filtration of industrial wastewater, the electrolytic anode is adopted, abd magnesium hydroxide generated in the electrolysis tank can effectively adsorb heavy metal ions in water and forms a floccule to subside, so that the heavy metal ions are separated from water; and the filtering device can effectively filter the sediment generated in the electrolytic tank to realize removal of heavy metals, so that water is purified.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to an environmental separation and purification device for electrolytic filtration of heavy metal ions in industrial wastewater. Background technique [0002] With the rapid development of industry, water pollution has become increasingly serious, which has become an unavoidable topic in today's society. As the types of pollutants in wastewater are becoming more and more complex, and the country's control on wastewater discharge is also stricter, traditional wastewater treatment technologies have been difficult to meet the requirements. Common electrolytic removal of heavy metals often leads to interruption of treatment due to anode consumption and water level changes, which affects the efficiency of sewage treatment. Moreover, it is easy to generate sediment in the electrolytic tank, and it is often impossible to filter heavy metals. Contents of the invention [000...
