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

Abstract

The invention discloses a physical method-based circular processing technology for bottle washing water and a device thereof. The technology and the device include four-level filtering: primary filtering for intercepting macroscopic impurities, self-cleaning filtering in filtering precision of 100mum, secondary filtering in filtering precision of 20mum and low-pressure ultra-filtration in filtering precision of 0.01mum. The technology and the device also include a back-flushing component and a CIP cleaning component. The physical method-based circular processing technology for bottle washing water is different from the traditional water purifying technology; the specific grading filtering method is adopted by the technology; the chemical agents required by the traditional technology are not added in the running process, so that the water can be more extremely recycled; four-level filtering measures are designed for the technology and different filtering precisions are arranged for the four-level filtering measures; especially, the filtering precisions from the second-level filtering to the fourth-level filtering are the optimal parameters acquired after the experiment; and a physical treatment technology is creatively utilized to clean the water and the sewage emission is reduced.

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.
