AI Technical Summary

Technical Problem

In traditional pipe direct drinking water systems, the instability of the SDI in the nanofiltration system leads to blockage, the ultraviolet disinfection effect is poor, and there are microbial resurrection problems, so the safety of drinking water cannot be guaranteed.

Method used

A direct pipe drinking water system is designed, including a water purification module, a blending module, a disinfection module and a water supply circulation module. The system removes harmful substances through ultrafiltration membrane components, further purifies water quality through desalination and organic components, and combines ozone and ultraviolet disinfection technology to ensure water safety.

Benefits of technology

Multi-level purification and disinfection of water is achieved, the safety of drinking water is ensured, the use of ozone is reduced, the generation of bromate is avoided, the maintenance cycle of the system is extended, and fully automated operation is achieved.

Abstract

The utility model relates to the technical field of direct drinking water systems, in particular to a pipeline direct drinking water system which comprises a water purification module and a blending module, the water purification module comprises a plurality of ultrafiltration membrane assemblies and desalting and organic matter removing assemblies, and the blending module is connected with the water purification module and used for adjusting the water supply proportion of the ultrafiltration membrane assemblies and the desalting and organic matter removing assemblies; the disinfection module is connected with the blending module through a sterile water inlet pipe; one part of the water supply circulation module is connected with the disinfection module, and the other part is connected with a user. The three disinfection modes are combined to inhibit microorganism breeding, water supply safety is guaranteed, the content of added ozone can be reduced, and the situation that disinfection by-products exceed the standard due to a single disinfection mode is prevented. The system realizes the effects of centralized purification and regulation of water quality, intelligent disinfection management and high-quality water supply, and has the advantages of capability of guaranteeing the water quality of direct drinking water and microbial safety, long maintenance period, full automation, no manual intervention and the like.
