Through the static test, the bactericidal agent suitable for the blast furnace water purification system was selected to oxidize the organic chloride chlorhexidine. The results show that under alkaline conditions, the bactericide has a higher bactericidal rate against heterotrophic bacteria, iron bacteria and sulfate reducing bacteria. The sterilization mechanism is also discussed in this paper.
The water pill is divided into two layers inside and outside, which has a disinfecting effect on drinking water. When it is used, it is directly added to an appropriate amount of water, and the outer layer of chlorinated (C 3 O 3 N 3 Cl 2 Na) is first reacted with water, and the obtained hypochlorous acid (HClO) has a bactericidal action. After a few minutes, the inner layer of sodium sulfite (Na 2 SO 3 ) removes residual chlorine (HClO, etc.) from the water. One of the reactions for removing residual chlorine: Na 2 SO 3 + HClO = Na 2 SO 4 + HCl, which is not a metathesis reaction.
The process characteristics of the excellent chlorine bleached linen yarn are introduced. The process is carried out under acidic conditions, which can effectively remove pigments, effectively remove lignin, and have less potential damage to the fibers. Bleaching provides excellent whiteness and maintains the original luster and style of flax fibers at a low cost.
