目前一般采用氯气或漂白粉处理医院含菌污水和消毒饮用水。对于无液氯供应的地区,尤其是偏僻地区和工地医院,氯气需要依靠运输,难以及时供应,而且不安全。漂白粉很容易分解,运输和存放过程中其消毒效果会逐渐降低,甚至失效。全国现有铁路医院100余座,沿线工地数千处,为保护环境不受菌毒污染和保护施工人员身体健康,急需 Chlorine or bleaching powders are currently used to treat hospital sewage containing bacteria and to sterilize drinking water. For areas where there is no supply of liquid chlorine, especially in remote areas and construction sites, chlorine needs to be transported, it is difficult to supply it in time, and it is not safe. The bleaching powder is easily decomposed, and the disinfecting effect during transportation and storage is gradually reduced or even failed. There are more than 100 existing railway hospitals in the country and thousands of sites along the site. It is urgently needed to protect the environment from bacterial contamination and to protect the health of construction workers.
