A kind of electrolysis-type sterilization and disinfection device, preparation method and application
Technical field
The invention belongs to water treatment technology field, sterilization is carried out to water body using electrolysis mode more particularly, to one kind
The functional module disinfected, preparation method and use.
Background technology
Swimming body-building is a kind of motion mode that people are liked, however, the health of swimming pool is but frequently subjected to the humiliation of people
Disease, it is primarily due to dissolve in a large amount of dusts of swimming pool, secretion and substantial amounts of bacterial reproduction and causes swimming pool water quality
Drastically decline, if purifying sterilizing not in time, most likely result in swimmer's skin, eyes, digestive system etc. and catch an illness.Existing side
Method is mainly utilized in the circulation filter put into outside chlorine class disinfectant and swimming pool in swimming pool.Using circulating filtration method cost
High, area occupied is big, and sterilization, filtering consuming time are long.Liquid chlorine disinfection method is advantageous in that easy, expense is low, can kill such as
Pathogen, virus and parasitic ovum etc..However, liquid chlorine belongs to high-risk violent in toxicity, liquid chlorine can produce many harmful in water
Material, such as chloroform, the liquid chlorine of surplus also can be to the skin of visitor, and the healthy aspect such as hair, eyes, respiratory tract is produced
Raw detrimental effect.It is always a developing direction of swimming pool industry without chlorine or less with chlorine.In addition, the manager of swimming pool
For the color for making pool inner water seems as clear as crystal, often using algicide (copper sulphate), this measure not only increased management
Cost, also easy influence people's is healthy, and the discharge of copper-containing wastewater also pollutes environment.Ozone is introduced in running water
Sterilization method, is the more popular another sterilization method in current market.The disinfection principle of ozone is the Strong oxdiative based on ozone
Performance, but solubility of the ozone in running water is limited, and ozone equally has greatly injury to human body, is chronically at ozone
In environment, dizziness is easily caused, more serious meeting causes the oxidation and perforation of lung's epidermal cell, so as to cause the diseases such as pneumothorax
Shape.Also one kind is disinfection by ultraviolet light mode, and this mode is difficult to be applied to inside water body, and has ultraviolet to irradiate human body
Injury.
