Anti-pollution reverse-osmosis water purification machine

Abstract

The invention provides an anti-pollution reverse-osmosis water purification machine, which solves the problems of poor quality, easy generation of secondary pollution and the like of water produced by the existing water purification machine. The water purification machine comprises a water inlet valve, a pre-filter, a booster pump, a post-filter and a water outlet faucet, wherein the water inlet end of the water inlet valve is connected with a water source; the water outlet end of the water inlet valve is communicated with the water inlet end of the pre-filter; the water outlet end of the pre-filter is sequentially connected in series with a low-voltage switch and a solenoid valve; the water inlet end of the booster pump is connected with the water outlet end of the solenoid valve; the post-filter is connected between the booster pump and the water outlet faucet; a high-voltage switch is connected between the water outlet faucet and the booster pump; and the water flows into the post-filter, flows through the high-voltage switch, and finally flows out of the water outlet faucet. The water purification machine has the advantages of pretreatment process simplification by using an ultrafiltration membrane for pretreatment and prevention of the problem of secondary pollution caused by a single active carbon filter element by replacing a traditional active carbon filter element with a composite hydrophilic membrane filter element.

Description

technical field [0001] The invention belongs to the technical field of domestic water purification and treatment, and relates to household water purification equipment, in particular to an anti-pollution reverse osmosis pure water machine. Background technique [0002] Water resources are the basic material for human beings to survive.

[0002] Water resources are the basic material for human beings to survive. However, due to the massive discharge of industrial wastewater and domestic sewage, some rivers and lakes have been seriously polluted. People's drinking water has been exposed to various germs, heavy metals and compounds that endanger human health. Pollution, with the improvement of people's living standards, modern people pay more and more attention to their own health, especially in terms of drinking water and health, people have higher and higher requirements for household water quality, tap water can no longer meet people's drinking water needs It is required that drinking drinking water after secondary treatment of tap water is very important to health has been generally accepted, so many drinking water filtration and purification treatment equipment have been developed to provide people with safe and hygienic drinking water

However, the traditional pure water machine mainly has the following problems: 1. After the source water is treated by the reverse osmosis membrane filter device, it will produce pure water and concentrated water with a ratio of 1:3, and the proportion is as high as three quarters. The concentrated water is directly discharged as waste water, resulting in serious waste of source water; 2. The purified water is stored in the pressure storage tank. If there is no drinking water for a long time, the pure water in the pressure storage tank will also It is possible to breed bacteria, thus affecting the safety and sanitation of pure water; 3. After the pure water machine is used for a period of time, the reverse osmosis membrane is prone to chemical scale, organic matter and colloid pollution, microbial pollution and other pollution, such as if it is not cleaned for a long time or not cleaned in time , it will damage the reverse osmosis membrane, thereby affecting the service life of the reverse osmosis membrane filter device

It can be seen that the pretreatment of the water purifier has the following disadvantages: 1. It adopts a multi-stage filter element structure, and multiple filter elements are connected in series. The pre-treatment process is complicated, resulting in a large volume of the whole machine, which affects product installation and maintenance. And promotion, and it is easy for bacteria and viruses to breed in the filter element, causing secondary pollution, resulting in a rapid decline in the life of the reverse osmosis membrane due to excessive bacteria in the water
