Water treatment device

Abstract

A water treatment device mainly comprises a feed water inlet, a membrane purification unit, a water inlet and a concentrated water outlet which are communicated with a water supply pipeline, wherein raw water flows into the feed water inlet, is purified through the membrane purification unit and then flows out of the water inlet to form purified water, concentrated water is discharged through the concentrated water outlet, and the membrane purification unit further comprises at least one ultrasonic generator which can carry out ultrasonic cleaning operation on a filter element in the membrane purification unit. Compared with the conventional technology, a technology adopts the ultrasonic generator to vibrate dirt which is accumulated in the filter element, the continuously increased water pressure of the filter element during the purification process is utilized to forcefully discharge the dirt with high pressure concentrated water quickly, and thus, the time for cleaning the filter element is shortened; and moreover, according to the water treatment device, the concentrated water outlet is closed during the water purifying process, so that wastewater discharge can be reduced, the purification efficiency is increased, and thus, water resources are effectively saved.

Description

technical field [0001] The invention relates to the field of drinking water purification equipment, in particular to a household or commercial water treatment equipment for purifying tap water. Background technique [0002] With the continuous advancement of world industrialization, whether in developed countries or poor areas, the problem of environmental pollution is becoming more and more serious, the increasing pollution of water resources, and the safety of drinking water have repeatedly touched people's fragile nerves, and gradually become a global challenge. In 2008 A group of news shocked the whole country: drinking tap water is unsafe, the water contains a certain degree of antibiotics and even sex hormones, although the content is low, but long-term drinking can also cause cancer, part of the pollution of tap water, the pollution is even more heinous, especially Calcium in tap water (Ca2 + ), magnesium (Mg2 + ) ions, carbonate ions, antibiotics, sex hormones, iro...

[0002]With the continuous advancement of world industrialization, whether in developed countries or poor areas, the problem of environmental pollution is becoming more and more serious, the pollution of water resources is becoming more and more serious, and the problem of drinking water safety has repeatedly touched the People's fragile nerves have gradually become a global challenge. In 2008, a group of news shocked the whole country: drinking tap water is unsafe, and the water contains a certain degree of antibiotics and even sex hormones. Although the content is low, long-term drinking can also cause cancer. Tap water Part of the pollution, the pollution is even more heinous, especially calcium (Ca2+), magnesium (Mg2+) ions, carbonate ions, antibiotics in tap water , sex hormones, iron, manganese, suspended solids, colloids, toxic by-products, bacteria, sediment, rust, and solid impurities pollution hazards, seriously exceeding the standard, some urban and rural tap water exceeded the standard, failing to meet the "Drinking Water Hygienic Standards of the People's Republic of China" 》, and the current situation of the above-mentioned pollution constitutes a great threat to the health of urban and rural people

[0003] In the well-known water purifier products on the market, the filter element used to purify the water inside the filter element will burn in the inner wall of the filter element after a period of use Excessive residual impurities that cannot flow out together with the concentrated water will lead to problems such as reduced pure water output, low water quality, and reduced service life of the filter element.

The traditional method is to replace the filter element with a new one, which will inevitably lead to waste of the filter element, because the filter element can still be used after regular cleaning and maintenance; in some industrial pure water machines, the filter element can be cleaned regularly, but its cleaning The efficiency is too low, a large amount of running water and cleaning fluid are required, and the entire cleaning process takes a long time

[0004] Another problem with traditional water purifiers is low filtration efficiency, especially for water purification equipment that filters through reverse osmosis membranes, usually producing 1 cup Pure water needs to discharge 4 to 8 cups of concentrated water, which is a serious waste, so the market popularity of traditional pure water equipment is not high
