3、outh DistrictDrainage Operation Ltd ., Shanghai 201203)Abstract: Soluble inert COD (SI)is a key index for the discharge standard of a wastewater treatment plant.Amodified SI determination method was established to eliminate the influence of soluble microbial products(SMP)onSI determination.Determina
4、tion results of domestic wastewater demonstrated good repeatability and accuracy of themodified method.According to the test results of wastewater from a long-distance combined sewer, SI/COD and SI/SCOD (soluble COD)fluctuated greatly in grab samples but were relatively steady in 24 h composite samp
5、les.SI/COD and SI/SCOD were respectively (9.20.3)% and (27.32.1)% in 24 h composite samples under dry weath-er, but increased significantly in samples under storm weather.Keywords: soluble inert COD;Activated Sludge Model;combined sewer S= x(IWA)4 C (ASMs) 1 , COD Vs y V 3COD(SS)、 V 3COD(XS)、 COD(SI
