Drinking water preparation device and drinking water preparation method adopting same

Abstract

The invention provides a drinking water preparation device. The drinking water preparation device is reasonable in arrangement. By filtering and purifying raw water, the outlet water is ensured to reach the standard of the drinking pure water. Meanwhile, the filtered drinking water is sterilized, so that the secondary pollution is prevented. The drinking water preparation device comprises a front filtering device and a reverse osmosis filtering device which are sequentially connected with each other by virtue of a pipeline, and is characterized in that a water purifying circulating and sterilizing device is arranged at the rear side of the reverse osmosis filtering device, the water purifying circulating and sterilizing device comprises an RO water production box, a drinking water circulating pump, a hygiene-grade titanium rod filter and an ultraviolet sterilizer which are sequentially connected with one another by virtue of a pipeline, the RO water production box is connected with a pure water outlet end of the reverse osmosis device, RO produced water is filtered by virtue of the hygiene-grade titanium rod filter to reach a water application site, the ultraviolet sterilizer is arranged between the RO water production box and the water application site, and the RO water production box is connected with the water application site by virtue of a circulating pipeline. The invention also provides a drinking water preparation method adopting the device.

Description

technical field [0001] The invention relates to the technical field of drinking water treatment, in particular to drinking water preparation equipment and a drinking water preparation method using the equipment. Background technique [0002] my country's water resources are scarce, and the pollution of water resources and the environment is becoming increasingly serious. Many water plants have to face the use of more polluted water whose water quality does not meet the requirements as a source of drinking water. With the improvement of people's living standards and the continuous enhancement of health and safety awareness, higher requirements are put forward for drinking water quality standards. In order to remove substances harmful to human health from contaminated raw water and improve the safety and reliability of drinking water, it is necessary to purify the raw water to meet drinking water standards. [0003] The Chinese utility model patent with the notification numb...

Problems solved by technology

[0003] The Chinese utility model patent with the notification number 2504258Y discloses a reverse osmosis water generator, which purifies and filters the raw water to meet the standard of drinking pure water through pretreatment and reverse osmosis filtration, and the filtered drinking water is stored in the produced water tank and transported to Water point, however, in actual use, long-term storage of drinking water in the water production tank will also breed bacteria, resulting in peculiar smell of drinking water. In addition, after long-term operation of the equipment, the accumulated particles and colloids will peel off into the drinking water and pollute the filtered drinking water
