In general, a sterilization process to remove harmful microorganisms such as viruses and pathogens is required in the purification process of drinking water or the reprocessing process of nutrient solution used for plant cultivation, and this sterilization process is mainly performed by physical and chemical methods .

Physical methods include dry heat sterilization, high-pressure steam sterilization, intermittent sterilization, UV or radiation sterilization, etc. These physical methods are methods of sterilizing harmful microorganisms by performing a long-term treatment process under high temperature or high pressure.

Accordingly, the sterilization method using a physical method has a disadvantage in that a long processing time is required to create a high-temperature or high-pressure state, and a high cost is required for manufacturing equipment for forming a high-temperature or high-pressure state.

In addition, the chemical method uses a toxic substance in a way to remove bacteria using a specific sterilizing agent and sterilizing gas, so there is a disadvantage in that it causes adverse effects on the human body and causes environmental pollution.

In recent years, sterilization devices using light, such as ultraviolet (UV) sterilization devices, have been widely used instead of physical and chemical sterilization methods.

The ultraviolet sterilizer is installed on the pipeline through which water or nutrient solution is moved, and has a structure in which an ultraviolet lamp is embedded inside a chamber body having a pipe shape, and the ultraviolet lamp is inserted into a quartz tube and installed inside the chamber body there is.

However, since the conventional ultraviolet sterilization apparatus described above has a complicated structure and is configured by connecting a plurality of expensive ultraviolet sterilization units 40, there is a problem in that the cost burden of consumers increases.

In addition, the above-described conventional ultraviolet sterilization apparatus has a disadvantage in that a large number of spaces are required and a long assembly time is required because a plurality of ultraviolet sterilization units 40 must be arranged and assembled.

In particular, the conventional ultraviolet sterilization apparatus described above has a limitation in that it cannot independently sterilize heterogeneous fluids having different types of sterilization target fluids (eg, heterogeneous plant cultivation nutrient solution having different components) or differently control the sterilization time of the fluids. . Accordingly, the conventional ultraviolet sterilization apparatus has a disadvantage in that compatibility in use is lacking and sterilization efficiency is lowered.

In addition, when the above-mentioned ultraviolet sterilizer is used for a certain period of time, inorganic substances and foreign substances are entangled in the quartz tube, reducing the light transmittance of the ultraviolet lamp and significantly reducing the sterilization effect. It is necessary to clean the quartz tube by physically removing it or pickling the stuck material using a chemical such as nitric acid.

The cleaning operation of the quartz tube takes an excessively long time in common, requiring a long downtime and high maintenance costs.
