Purification and Treatment Technology for Heavy Metal Wastewater in Wet Metallurgy Considering Environmental Protection Concepts
In order to achieve water quality purification of heavy metal wastewater and improve sewage treatment effificiency,research on wet metallurgical heavy metal wastewater purification technology is carried out under the consideration of environmental protection concept.During this process,install a heavy metal wastewater treatment device for wet metallurgy.Design the dosage of collector and foaming agent in flotation agent based on the mode of action of the collector.Design a flotation based method for heavy metal ion precipitation and purification treatment of raw water by adding precipitants such as sulfides and hydroxides at the inlet of the arranged wastewater treatment device.The comparative experimental results show that using the designed method for wastewater treatment,the pollutant content in the treated wastewater can reach the emission standard limit,that is,achieve purification treatment,and meet the practical application needs.
