摘要：Experiments on microbial degradation with hydrolytic acidification-aerobic (membrane bioreactor) MBR process were conducted to treat the pulping midcourse wastewater (PMW) with chemical oxygen demand (COD) concentration of 1,182mg/L, chromaticity of 327PCU, and TSS concentration of 153mg/L. Rumen micro-organisms (RM) were used in the hydrolytic acidification process. The experimental results demonstrated that the hydrolytic-aerobic process could raise the biodegradability of the PMW, the VFA concentration could reach 200mg/L, and the acidification rate was 24%; the effluent COD could reach 96mg/L, the chromaticity 80PCU, and the TSS 15mg/L. These results suggested that hydrolytic acidification via RM and aerobic MBR could be a promising way for effective disposal of puling midcourse wastewater.
