对于饮用水消毒或循环水杀菌目前普遍采用加氯方法。用液氯消毒效率较高,设备简单,但计量准确性及管理的安全性方面还有不少要解决的问题,要进行自动加氯气,技术上困难较多。最近,我们用次氯酸钠进行水的消毒试验,结果表明这工艺计量稳定,安全可靠,容易管理,自动投加有更大可能性,处理后水呈弱碱性,可以提高水的稳定性,防止水的侵蚀作用。
For the disinfection of drinking water or the sterilization of circulating water, chlorination methods are generally used. Disinfection with liquid chlorine is more efficient and equipment is simpler, but there are still many problems to be solved in terms of accuracy of measurement and safety of management. It is technically more difficult to perform automatic chlorine addition. Recently, we used sodium hypochlorite to disinfect the water. The results showed that this process is stable, safe and reliable, easy to manage, and has a greater possibility of automatic dosing. After treatment, the water is weakly alkaline, which can improve the stability of the water and prevent water. The erosion effect.
