Physical method-based circular processing technology for bottle washing water and device thereof

Abstract

The invention discloses a cycle treatment process and device of a physical method for washing bottle water. The process and device include four stages of filtration: primary filtration for intercepting impurities visible to the naked eye, self-cleaning filtration with a filtration accuracy of 100um, and precision filtration with a filtration accuracy of 20um. Filtration and low-pressure ultrafiltration with a filtration accuracy of 0.01um; and includes backwash components and CIP cleaning components. This process of recycling physical method of bottle washing water is different from the traditional water purification process. Recycling; this process design has four levels of filtration measures, and each level of filtration measures is equipped with different filtration precision; in particular, the filtration precision from the second level of filtration to the fourth level of filtration is the best parameter obtained through experiments , Creatively use physical treatment technology to clean water and reduce sewage discharge.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to a process and a device for recycling bottle washing water in a physical method. Background technique [0002] In the food and beverage industry, many companies use glass bottles for product packaging. Glass containers need to be cleaned and sterilized before filling, and this process is mainly used for cleaning glass containers. Due to the large amount of cleaning water, direct treatment of discharge will bring a lot of waste of water resources and environmental protection problems, while the traditional water purification process often requires a large amount of chemical agents, which will bring new pollution sources and environmental protection problems. Chemical pollution components will gradually concentrate, which is not conducive to recycling. [0003] Process status: [0004] 1. The cleaning water is directly discharged or discharged to the sewage tr...

AI Technical Summary

Problems solved by technology

Because the chemical components will be gradually concentrated, it is not feasible for long-term recycling, and it still needs to enter the sewage treatment process or be discharged directly. The overall utilization rate is less than 50%, and the problems of waste of water resources and environmental protection and sewage discharge are still not solved.
