- Abstract:
-
Two composite coagulants are used: polyaluminum chloride (PAC) and polyacrylamide (PAM) and ferrous sulfate and polyacrylamide. The removal effect of COD and SS from lincolmycin wastewater was experimentally studied under different pH values and dosages. The test results show that PAC+PAM has a good removal rate compared with ferrous sulfate+PAM when the pH value is 2 and the dosage is 12 mg/L. And the removal rate reached the maximum; The removal rates of COD and SS were 300.22% and 05.32%, respectively.The coagulation precipitation method could be used as the pretreatment unit of lincolmycin wastewater biological treatment system to reduce the pollutant concentration in wastewater. Reduce the load of biological treatment.
