Background

In recent years, water-borne pathogenic bacteria are attracting more and more attention, and especially the pathogenic bacteria can be propagated in a water distribution network system, thereby threatening human health. The water disinfection is an effective way for removing pathogenic microorganisms in water, preventing water-mediated infectious diseases from spreading and ensuring the sanitation and safety of drinking water. At present, common methods for disinfecting tap water can be classified into physical disinfection techniques and chemical disinfection methods.

The physical disinfection technique commonly used therein is ultraviolet disinfection. The ultraviolet disinfection technology is simple to apply, microorganisms in drinking water can be effectively inactivated under the conditions of low dosage and short retention time, but the requirement of ultraviolet disinfection on the quality of inlet water is high, the ultraviolet disinfection and sterilization capacity is related to the radiation time and intensity, and in addition, an ultraviolet lamp also needs to be regularly cleaned and replaced, has no continuous sterilization capacity and has the risks of regeneration and secondary pollution.

Commonly used chemical sterilization methods include chlorine, chlorine dioxide, chloramine, ozone sterilization. Because chlorination disinfection has the characteristics of good effect, low cost and the like, most of drinking water in China is disinfected by traditional chlorination at present. Chlorination works mainly by hypochlorous acid, which enters water to react to form hypochlorous acid, permeates to the surface of negatively charged bacteria, penetrates cell walls to enter the bacteria, and destroys the bacterial enzyme system through oxidation to kill the bacteria. However, the chlorine disinfection method is easy to react with organic matters coexisting in water, such as Natural Organic Matters (NOMs), to generate Disinfection Byproducts (DBPs) such as halogenated alkanes and halogenated aromatic hydrocarbons, and the substances have high toxicity, have risks of carcinogenesis, teratogenesis and mutagenesis, and have great threat to human health.
