Disinfection well for ultraviolet sewage treatment by using microwaves

Abstract

The invention is applied to ultraviolet sewage treatment in the field of environmental protection. Lamp tubes, the conventional equipment for ultraviolet sewage treatment, have low electrode efficiency and short lives, have large floor areas because of using open channels for flowing and have poor effects. The invention adopts the microwaves sent out by magnetrons as the energy sources. The ultraviolet quartz lamp tubes are arranged in a cylindrical microwave resonance cavity body, are filled with mercury and protective gases, emit ultraviolet light under microwave excitation, have no electrodes and have long lives. A facility for current to flow in and out, with a cylindrical well type structure, and a spiral diversion facility installed in the facility for current to flow in and out canenable water to be fully contacted with the ultraviolet rays, thus obtaining good sterilization effects. The floor area of the invention is only a small percentage of that of the conventional equipment for ultraviolet sewage treatment.

Description

technical field [0001] The invention belongs to the technical field of environmental protection equipment, in particular to ultraviolet sewage treatment and disinfection equipment. Background technique [0002] Bacteria in water are killed under the irradiation of ultraviolet rays. This is a new technology developed in recent years. It is an effective method of water treatment. It is used in the field of water disinfection and is called ultraviolet water treatment and disinfection equipment. The existing ultraviolet water treatment and disinfection equipment generally adopts the form of open channel flow, which occupies a large area and the equipment for regulating the flow is complicated. The core part of the equipment, the ultraviolet lamp tube has electrodes, and its disadvantage is that the photoelectric conversion rate is low, and the luminous efficiency gradually decays with the use time, and the service life is only about 10,000 hours. This kind of equipment needs to ...

The existing ultraviolet water treatment and disinfection equipment generally adopts the form of open channel flow, which occupies a large area and the equipment for regulating flow is complicated

The core part of the equipment, the ultraviolet lamp tube has electrodes, and its disadvantage is that the photoelectric conversion rate is low, and the luminous efficiency gradually decays with the use time, and the service life is only about 10,000 hours. This kind of equipment needs to replace the lamp tube frequently, and the maintenance period is short and the cost is high.
