Embodiment Construction

[0022] specific implementation plan

[0023] As shown in Figure 2 of this embodiment, the system device includes the following main components: water inlet valve 1, booster pump 2, sand filter 3, activated carbon filter 4, water softener 5, microfilter 6, fine filter 7, high pressure Pump 8, nanofiltration membrane filter 9, reverse osmosis membrane filter 10 and 11, ultraviolet sterilizing device 20, chlorination device 21 and water purification and storage device 22. The system is first connected in sequence in the order of water inlet valve 1, booster pump 2, sand filter 3, activated carbon filter 4, water softener 5, microfilter 6, fine filter 7, and high-pressure pump 8. The water outlet of high-pressure pump 8 is divided into Two paths, one path is connected to the water inlet of the nanofiltration membrane filter 9 through the flow control valve 14, the flowmeter 13 and the pressure gauge successively, and the concentrated water output of the nanofiltration membrane fil...

Abstract

The present invention provides production process and system of piped drinking water. The water purifying treatment process includes sand filtering treatment, active carbon filtering treatment, water softener treatment, microfilter treatment, fine filter treatment, pressurizing, filtering with nanofiltering film and reverse osmosis film, ultraviolet ray irradiation and chlorine disinfection, and the treated water can reach the standard of drinking water. The production process and system of the present invention is suitable for various kinds of water source, especially water source with high TDS and water source with high TOC, and the purified water has proper amount of life elements maintained and high quality.

Description

technical field [0001] The invention relates to a production method of drinking purified water and an equipment system thereof. Background technique [0002] With the improvement of people's living standards, the requirements for drinking water quality are getting higher and higher, and the existing water treatment technology of waterworks is difficult to produce higher standard drinking water. It has become a development trend to carry out advanced drinking water treatment technology research to produce higher quality drinking water. At present, direct drinking water production generally adopts membrane filtration. There are three commonly used membranes: reverse osmosis membrane, nanofiltration and ultrafiltration. The removal effects of these three membranes on trace amounts of toxic and harmful substances are quite different, and the conditions of use are also different. The ultrafiltration membrane cannot remove inorganic substances, but can only remove organic subst...
