Abstract
Two different methods for treating an acid wastewater from lead-zinc p rocessing industry are compared. The results obtained show that chemic al treatment (neutralization alkalization and precipitation by means o f NaOH addition) is a better method than electrochemical treatment wit h Fe electrodes for the heavy metal ions' diminution, in the case when the initial heavy metal concentrations are relatively law.
