Determination of textile dyeing wastewater COD components by comparison with respirometry and full-scale data.
A Modified Activated Sludge Model No. 1 (M-ASM1), including six COD components (S1, S(S), X1, X(S), X(H), and S(O)) and three biochemical processes (aerobic growth of heterotrophs, aerobic decay of heterotrophs and hydrolysis of entrapped organics) was used to simulate the anaerobic hydrolysis-aeration-sedimentation treatment series in a full-scale textile dyeing wastewater treatment plant (WWTP) with an influent flow rate of 200,000 m3/d. Using a respirometry method, the influent COD components of the WWTP activated sludge system were estimated. Then, calibration equations were set up depending on the full-scale treatment plant running data in order to calibrate the measurement results. This paper indicates that the influent COD components of a low biodegradability wastewater can be estimated using a respirometry method coupled with a calibration procedure based on full-scale plant running data.
