摘要
Abstract
Ningdong Water Plant is faced to treat water with low temperature and low turbidity. Experiments were carried out and results were achieved as follows:(1)The best removal efficiency of turbidity and UV254 was obtained with adding KMnO4 and KFeO4 followed by adding PAC,removal efficiency by simultaneous addition of 3 reagents was the next,the worst removal efficiency of turbidity and UV254 was obtained with adding PAC followed by adding 2 potassium salts;(2 )There was an optimal dosage of these 2 potassium salts;(3)Pre-oxidation was better under acidic condition;(4)Purified Al13 could significantly decrease turbidity after sedimentation.关键词
