Abstract

The invention relates to a direct drinking water system and process for purification treatment on raw water. The direct drinking water system comprises an ultrafiltration device, an activated carbon filtration device, a reverse osmosis device and a circulating pipe network which are connected with each other sequentially through a conveying pipeline. Raw water is filtered by the ultrafiltration device, the activated carbon filtration device and the reverse osmosis device respectively, and then the treated direct drinking water is conveyed to each point of use through the circulating pipe network, and therefore, circulating supply is realized. In the circulating pipe network, the points of use of water are connected in series to effectively guarantee the sanitation and the safety of the direct drinking water. The direct drinking water system comprehensively meets the sanitation requirements on the direct drinking water, is good in universality and can be applied to purifying various types of raw water to produce the direct drinking water.

Description

technical field [0001] The invention belongs to the field of drinking water treatment, in particular to a drinking water advanced treatment system and process, in particular to a direct drinking water system and a direct drinking water production process. Background technique [0002] Water treatment is the process of removing some harmful substances that are unnecessary for production and life in water through physical and chemical means. It is a process of water quality conditioning such as sedimentation, filtration, coagulation, flocculation, corrosion inhibition, and scale inhibition for specific purposes. [0003] The so-called direct drinking water refers to the raw water that has undergone advanced treatment and purification by special processes to remove organic matter, bacteria and viruses in the raw water, retain trace elements in the water that are beneficial to the human body, and output it to the water that users can drink directly. The water source of direct d...
