Measures to control microbial pollution Pure water is a special product. Once contaminated by a few microorganisms, it may exceed the standard and even cause flocculent precipitation. Therefore, controlling microbial pollution is a very important work for production enterprises. The above analysis shows that the measures to control the microbial pollution of pure water should be comprehensive, and one aspect should not be overemphasized, while other aspects should be ignored, because any link in the production process will be polluted, thus affecting the quality of products.

1, strengthen self-hygiene management, strengthen food hygiene quality awareness, appoint a leader to be responsible for hygiene work, set up full-time hygiene inspection institutions, strengthen the detection of water source, packaging, air and products in the filling room, formulate hygiene management systems from water source management, sterilization, filling and packaging to personal hygiene, designate special personnel to supervise the implementation, strengthen the training and learning of food hygiene knowledge, focus on mastering disinfection methods, and clarify the key links that microorganisms are easy to pollute.

2. According to the characteristics of water source, design the production process reasonably and scientifically, equip with necessary water treatment and production equipment, and choose a sterilization system that meets the disinfection of water quality. In China, ultraviolet, ultrafiltration and ozone are mostly used as disinfection facilities for mineral water and pure water. However, years of experience have proved that the poor reliability of the first two types is the main factor that causes the unqualified products, and ozone sterilization is considered to be the best method at present.

3. Regularly strengthen the cleaning and disinfection of pipelines, containers and filters in the whole production process, and do a good job in disinfection of bottles, lids and filling rooms. It is understood that chlorine dioxide (ClO2 _ 2) is used for disinfection of pipelines and packages of most manufacturers, and has strong oxidation and disinfection effects. However, the quality control of disinfection drugs should be strengthened to ensure its disinfection effect.
