Background

The chlorination disinfection is a disinfection means widely used in urban water treatment, and has the advantages of low cost and strong sterilization capability. However, when the organic content of the source water is somewhat high, chlorination will produce chlorinated organic compounds, i.e., chlorinated disinfection by-products (DBPs). Most chlorinated organic compounds have carcinogenicity, teratogenicity and mutagenicity, and the three-induced by-products have long-term toxic and side effects on aquatic organisms and human health. Therefore, it is imperative to remove chlorine disinfection by-products from drinking water.

The photocatalytic degradation of organic matters refers to a technology that a catalyst generates photo-generated electrons or holes under the condition of auxiliary illumination so that the organic matters in an organic matter aqueous solution are degraded.

Among many materials, titanium dioxide (TiO2) has been one of the hot spots in the research of photocatalytic materials due to its good light stability and non-toxic effect. Research shows that the nano TiO2 photocatalytic technology has the outstanding advantages of mild application conditions, wide application range, small selectivity, simple and convenient operation, capability of effectively reducing secondary pollution and the like.
