【 摘 要 】

Being an internationally accepted standard for the activated sludge modeling, the Activated Sludge Model No.1 (ASM1) was used to simulate the treatment of paper mills effluent in an industrial full-scale sequencing batch reactor (SBR). Key characteristic parameters were estimated and corrected with the wastewater temperature: maximum heterotrophic growth rate mu(H) (9.69/day), heterotrophic yield Y-H (0.625 g cell COD/g COD oxidized) and heterotrophic decay rate b(H) (1.98/day). The wastewater chemical oxygen demand (COD) was fractionated as slowly biodegradable substrate X-s (20%), particulate inert organic matter X-I (58%), readily biodegradable substrate S-s (18%) and soluble inert organic matter S-I (4%). Finally, the SBR operation was simulated with field data from the paper mill. The average relative error of the simulated effluent COD was 12.7%. The results showed that the ASM1 could be reasonably used in the papermaking wastewater treatment simulation. (C) 2017 Elsevier Ltd. All rights reserved.
