Abstract :
Sorption experiments of triclosan (TCS) were carried out on different sludge (anaerobic, aerobic and anoxic sludge) in different type (activated sludge, sterilized sludge and antibacterial sludge). The sorption models under different temperatures (10, 20 and 30°C) were investigated and the corresponding sorption coefficients were calculated. The results showed that TCS sorption agree with the Freundlich and Henry linear sorption model, and the coefficients Kd and KF varied with the increasing of temperature. TCS sorption show no significantly difference on activated sludge or antibacterial sludge, so the antibacterial sludge can be used in sorption experiment in stead of activated sludge. According to the validation experiment of sorption coefficients in sewage treatment system, TCS sorption on activated sludge agree with linear model, the sorption ratio on the sludge can be predicted by the linear distribution coefficient Kd.
