| Abstract: | The stepped disposal method was studied to decrease lead and cadmium ion in the draining wastewater from acid preparation and good results were obtained.The experiment results shown that using the stepped neutralization method,first adjusting the wastewater's pH to 12.0,the removing rate of cadmium ion reached up to 97.4%;and then adjusting its pH to 8.5 after settling and filtration,the removing rate of lead ion reached up to 98.0%. |
