- Abstract
The obvious features of artificial stone wastewater are high SS and COD concentration, and the wastewater cannot meet the discharge standard. Three-stage coagulation procedure was adopted to dispose wastewater by controlling the different coagulants, coagulant dosage and pH value in this study. The results showed that aluminum sulfate was acted as coagulant and the dosages were 56.70mg/L,16.00mg/L and 7.50mg/L respectively in the three-stage coagulation procedure, the supernatant SS of wastewater was 8.8mg/L, the turbidity was 6.9 NTU and COD was 73.65 mg/L. Based on the three-stage coagulation procedure, the supernatant was further to be adsorbed by diatomite. When the pH was 6.40, the dosage was 20 g/L, and the supernatant COD was 16.80 mg/L, the supernatant, treated by three-stage coagulation procedure, can be directly used for production.
