Analysis of disinfection technologies for water with different qualities

Different water quality has different influence on disinfectant.It is necessary to select appropriate disinfection technology.This paper describes the principle and characteristics of disinfection process,including the chlorination,chlorine dioxide disinfection,ozone disinfection,UV disinfection and TiO2 Photoeatalytie oxidation.In view of the different surface water with high turbidity,high algae and high organic,and the different groundwater with organic(oil) pollution and with excessive iron and manganese,based on disinfection by-products and microbial inactivated effect,various disinfection technologies are compared and suitable disinfection technology is chosen for specific water.
