The feasibility of reuse has been studied through the experiments of flocculation,scale and corrosion inhibition. The result shows that if it is treated properly,the turbidity of the circulating water can be decreased to 60 NTU,the scale and corrosion inhibition efficiency can be 99% and 95.6%,respectively,the corrosion rate is less than 0.078 mm/a. It is concluded that the coking w... 查看更多0个回答 . 2人已关注
