粉末活性炭吸附长江原水中微囊藻毒素的影响因素
Influence Factors of Adsorption with Powdered Activated Carbon for Microcystins Removal in Raw Water of Yangtze River
摘要
Abstract
Bottle point experiments were carried out to investigate the effect of powdered activated carbon(PAC) on the removal of MC-RR and MC-LR in Yangtze River raw water. The influences of pH, PAC dosage and prechlorination were also analyzed during the adsorption in different solutions. The results showed that 86 % MC-RR and 71 % MC-LR were removed when adding 10mg/L PAC and reaching equilibrium state. In particular, the adsorption of MC-RR on PAC has greater capacity and faster rate than MC-LR. If more PAC is fed, the removal effect of MCs does not change much while reducing pH to a weakly acidic condition is more propitious to remove MCs by PAC. The influence of MCs removal effect by prechlorination is complicated, depending on the feeding mode of chlorine and PAC.关键词
