The ultraviolet rays Handler to process the sterilization .

The DNA are especially vulnerable in wavelength 200-290mm. so the uv led strip with wavelength 200-290mm can control special hereditary phenomenon and DNA (deoxyribonucleic acid) through of Bacteria or viruses .( In the biological treatment systems, different kinds of microbes ‘growing and metabolizing need necessary elements including carbon, hydrogen, oxygen, nitrogen, phosphorus, sulfur, and so on, also need microelement including Fe Na and so on) the way can make Bacteria or viruses lose nutrient supply and their ability to reproduce., They were more weak and also enjoyed lower fertility .we will effect my purpose.

Due to various microorganism has varying levels of sensitivity. for ultraviolet rays. base on Bacillus strain(B.subtlis)we make experiments showed that Its bactericidal rate was 99.5% on D 10= mw.s/cm 2 (exposure).
