One of the main source of heavy metal wastewater is the electronics industry. If treated ineffectively, it may be discharged into water bodies, causing water body pollution and endangering human health. Traditional treatment methods have a poor quality of wastewater and high treatment process costs. This subject takes the low concentration of lead and copper wastewater from a lead storage battery factory as the research object, and uses the principle of the precipitation of Thiobacillus acidophilus to remove lead and copper from the wastewater. The results show that at a temperature of 30°C, pH of 2.5, and rotation speed of 130r/min, acidophils have the highest removal rate of 74.69%, 38.48% for lead and copper, respectively.
