The Principle and Application of Ultraviolet Germicidal Lamp 1

Sterilization lamp, popularly speaking, mainly plays the role of sterilization and disinfection, also known as UV lamp, which is a kind of UV lamp with lower intensity. It uses lower mercury vapor pressure (<10-2Pa is stimulated to cause ultraviolet light, and its emission spectrum mainly has two lines: one is 253.7 nanometer light wavelength, the other is 185 nanometer light wavelength, these two full It is ultraviolet light that is invisible to the eyes. The spectrum of 253.7 nanometers of light wavelength can play a very good sterilization. The main principle of sterilization is based on the absorption line law of cells to light waves: the wavelength of cells to light is 250-270 nanometers The amount of ultraviolet light absorbed is large, and the absorbed ultraviolet light can affect the genetic material (DNA) of the cell, causing it to cause photochemical action, and the energy of ultraviolet photons is absorbed by the base pairs in DNA, resulting in genetic Substances mutated, causing bacterial viruses to kill immediately or fail to reproduce offspring, reaching the goal of sterilization.

So, when we are usually feeding ornamental fish, when should we use germicidal lamps?

1. Fish tank bacteria boom

Fish tank bacteria boom usually show that the water changes from clear to bottom to turbid in a short period of time. After the water explosion in the fish tank, a germicidal lamp can be used to suppress the reproduction of the bacterial virus or kill the bacterial virus. In this case, you can change part of the water and turn on the sterilization lamp for 2 hours. After turning off the lamp, you can improve it by adding nitrifying bacteria.

There are many factors that can cause the fish tank bacteria to boom. For example: too many fish, too much organic matter caused by feeding and fish excrement causes a large number of foreign bacteria to multiply, or a large number of cleaning filters at a time can cause fish tank explosion bacteria.
