紫外线—臭氧组合式消毒机主要由六部分组成:臭氧发生器、紫外线消毒器、控制部分、循环管路、水泵和机架(图1)。该技术适合封闭式无土栽培系统,营养液循环利用时的消毒使用。1工作流程营养液池中待消毒的营养液由水泵以一定的流速、流量抽进消毒机,首先经过过滤器去除其中的杂质,然后进入文丘里射流器;臭氧发生器产生的臭氧,被文丘里管吸入管道与营养液混合,并开始杀灭其中的病原菌;从文丘里管流出的营养液随后进入紫外线消毒器,营养液受到紫外线照射再次进行消毒。消毒处理后的营养液最后由紫外消毒器出液口
UV - ozone combination disinfection mainly consists of six components: ozone generator, UV sterilizer, control section, circulation lines, pumps and racks (Figure 1). The technology is suitable for closed soilless cultivation system, disinfection when the nutrient solution is recycled. 1 Workflow Nutrition liquid pool to be disinfected nutrient solution by the pump to a certain flow rate, flow into the disinfection machine, first through the filter to remove impurities therein, and then into the Venturi jet; ozone generator ozone, was Venturi The tube suction pipe mixed with the nutrient solution, and began to kill the pathogen; the nutrient solution from the Venturi tube and then into the UV sterilizer, nutrient solution by UV irradiation disinfection again. After disinfection of the nutrient solution by the UV disinfection liquid outlet
