Abstract

PURPOSE: To improve efficiency of treatment in removing heavy metals from waste water containing carbonates by performing floatation separation, coagulation settling and coagulation settling under the coexistence of a heavy metal collector, adjusting pH successively.
CONSTITUTION: pH of waste water containing heavy metals and carbonates is adjusted to below 7 and well-known floatation separation is performed. Then, pH of the waste water subjected to the floatation separation is adjusted to 8W12 and well-known coagulation settling treatment is performed. After completion of the above treatment, pH of the waste water is adjusted to below 7 and coagulation setting treatment is performed under the coexistence of a heavy metal collector. Organic agent such as "SumiflockHM-2,000" is desirable as the heavy metal collector.
