摘要: Abstract This work investigated the rheological behavior of sludge in a long-running digestor and established timely approach for monitoring torque information an anaerobic process. With multi-methods, within were revealed, which indicated that: (1) on-line sensing was efficient method to obtain signals, could give reliable prediction variation sludge, further provide useful monitor operation digestor; (2) thixotropic index decreased continuously along with operational time, showed weakening tendency interaction among particles; (3) both content total suspended solids (TSS) extracellular polymeric substances (EPS) had close relationships limit viscosity but TSS positive impact, while, impact EPS negative.
