Abstract

This paper research aerobic excess sludge come from A / O process in sewage treatment plant of a paper mill in Shandong, china. The content of TCOD, SCOD, TSS, VSS, P043--P and NH4 +-N in this sludge is studied ,while, the feasibility that aerobic excess sludge and papermaking wastewater in the same time. The results showed that the theoretical gas production is 1.2m3/VSS.kg in mesophilic digestion;The release of P043--P and NH4+-N achieve the best emissions in pH 7.0 ~ 8.0. Within 20 days of continuous experiment, the release of P043--P and NH4 +-N comes from aerobic excess sludge is 1.5mg/ L and 5.0mg/ L, respectively. The SCOD increase 50-100 mg /L, in this process. The treatment efficiency of papermaking wastewater is not greater impacted. The release of P043--P and NH4+-N in this process can replace the added urea and phosphate in water treatment water treatment.
