摘　　要：以天津市某净水厂生产用原水和调节池进口原水为试验原水进行混凝和吸附试验,通过在不同工艺点投加粉末活性炭,考察不同吸附时间下相关水质参数的变化规律,选择适宜的去除原水嗅味的粉末活性炭投加点和投加量。试验结果表明,在加聚合氯化铝前投加粉末活性炭对生产用原水嗅味的吸附去除效果最好,调节池进口原水投加15 mg/L粉末活性炭搅拌5 min后静置2 h对嗅味的处理效果最好。The coagulation and adsorption tests of the raw water for production and the raw water from the regulating tank of a water purification plant in Tianjin were carried out.The powdered activated carbon was added at different process points.The change rule of relevant water quality parameters under different adsorption times was investigated,and the appropriate dosing point and dosage of powdered activated carbon for odor removal of raw water were selected.The results show that dosing powder activated carbon before polyaluminium chloride has the best adsorption and removal effect on the odor of raw water for production.Dosing 15 mg/L powdered activated carbon in the raw water at the inlet of the regulating tank and stirring for 5 minutes and then standing for 2 hours have the best odor treatment effect.
