Development of Ecologically Safe Air Cleaning Technology for Greenhouses
Greenhouse vegetable growing in Russia is one of the priority and dynamically developing areas of agriculture, and the production of quality food is one of the goals of the strategic development of Russia. The development of environmentally friendly methods of air disinfection, recycling containers and pest control in greenhouse plants is important. For this purpose, a chemical method of disinfection with aerosol generators spraying disinfectant is used. (Research purpose) The research purpose is to study the effect of ultraviolet radiation and ozone on microbial contamination of air in greenhouse plants. (Materials and methods) We developed an ozone generator operating in un-dehumidified open air. The generator produce ozone by corona discharge. We selected lamp TUV PL-L as UV source for the second component of disinfection from microorganisms. (Results and discussion) We have shown that ozone has a profound bactericidal effect compared with the use of ultraviolet radiation. Ultraviolet has little effect on the humidity change in the room. (Conclusion) We have proposed the revised method for calculation of ozone concentration and the performance of the ozone generator. We performed the experimental studies of the effect of ultraviolet radiation and ozone on microbial contamination in chamber boxes.
