Description
Summary:The article discusses the treatment of wastewater containing heavy metal salts before releasing it into natural water bodies or the urban drainage system. The focus is on environmental protection, human health, and the potential for recovering valuable metals from wastewater. A vertical settling tank was selected for its cost-effectiveness in treating metal-containing acidic wastewater. The article provides a general method for calculating these settling tanks during reagent sedimentation, which can be used to remove various types of heavy metal salts. For this purpose, all calculations related to the use of reagents (their quantities, volumes of reagent storage, solution tanks, and neutralization chambers) were conducted in advance. Additionally, corresponding chemical equations for the reagents and various acids, as well as the equations for the reactions occurring between the reagents and heavy metal salts, were formulated.
