Through static experiments， it is found that these two methods have a better inhibiting effect on water samples with shorter circulation time and lower concentration ratio. YC2655 scale inhibitor has the best inhibiting effect among PC2566， YC2655 and YL505 polycarboxylic acid scale inhibitors. For circulating water that has been circulated for 1 month， magnetic scale inhibitor has a higher anti-scaling rate than dosing polycarboxylic acid scale inhibitor， and its anti-scaling rate is up to 96%. Electrical conductivity and pH can reflect scaling tendency， the smaller electrical conductivity and pH， the smaller scaling tendency of water samples. Therefore， through the detection and comparison of untreated water samples and water samples treated with the above two methods， by analyzing the change rules of their conductivity and pH over time， it is found that the magnetization treatment has a better and more stable anti-scaling effect than dosing scale inhibitor. Finally， it is concluded that compared with dosing
