Field energy sterilization alga destroying apparatus

The utility model relates to a field energy sterilization alga destroying apparatus, which is provided with at least six drum bodies, wherein, inside each drum body can only be arranged one of a high voltage electrostatic field generator, a high frequency electric field generator or an UV/nmTiO2 generator with at least one high voltage electrostatic field generator, at least three high frequency electric field generators and two or three UV/nmTiO2 generators being arranged; one of the drum bodies switched into conduction through a water diversion pipe and provided with the high voltage electrostatic field generator inside is provided with a water inlet and a water outlet; the other one switched into conduction through a water diversion pipe and provided with a high frequency electrostatic field generator inside is also provided with a water inlet and a water outlet; another one switched into conduction through a water diversion pipe and provided with the UV/nmTiO2 generator inside is also provided with a water inlet and a water outlet; while the rest provided with the above three types of generators are connected in series and switched into conduction in turn. The utility model can exterminate bacteria and alga in water and realizes effective degradation of organic pollutants without secondary pollution.
