A Study of Treatment of Yellow River′s Water by Combined Use of Active Carbon Powder and Potassium Permanganate

A static experiment was used for investigating the effect of active carbon powder and potassium permanganate when they were used in a combined way with different dosage and add sequence on the removal of organic matters in raw water from yellow river, the results of the test show that: in view of raw water from yellow river which turbidity is 7.7 NTU, water temperature is 4 ℃,when the dosage of active carbon powder is 10 mg/L, the dosage of potassium permanganate is 1.0 mg/L, the best result of organic removal can be obtained by dosing the both contemporarily, meanwhile, the flocculation performance is also better strengthened.
