| Abstract: | Reclaimation of waste alkali from paper-making wastewater by using a pyrite slag-based coagulant And physicochemical method was studied. The result showed that reclamation rate of waste alkali reached 65%,a caustic alkali(17-25g/L) was obtained, and reduction rate of COD was 80%,profit can be obtained from alkali, which was reclaimed from paper-making wastewater ,and can reach 400 yuan/1000 kg, The result indicate that the method can be used in large field. |
