Description

Filtering component for water purifier

Technical Field

The utility model relates to a water purification filters technical field, indicates a filter assembly for water purifier very much.

Background

With the rapid development of economy, the living standard of people is remarkably improved. With the attendant environmental problems that are becoming more and more severe. At present, the drinking water source pollution in China is mainly characterized in that ammonia nitrogen and organic matters in water of a water source are greatly increased, the three causes (carcinogenesis, teratogenesis and causing outburst) of water are greatly enhanced, and the traditional water treatment process has the limitation of removing the pollutants, so that the phenomenon of 'no water eating while staying on water' appears in many places.

The tap water contains a lot of harmful substances, such as soluble heavy metal ions, excessive residual chlorine, rust, bacteria and viruses. The common process for tap water generally comprises three steps: coagulating, adding aluminum chloride, aluminum sulfate or ferric chloride into raw water to generate substances such as suspended matters, colloids and the like which are easy to precipitate and crystallize; then the mixture enters a sedimentation tank, after sedimentation for a certain time, the mixture flows out and is filtered by a turnover plate consisting of quartz sand, and finally liquid chlorine is added for disinfection treatment. Tap water treatment processes are primary filtration of hundreds of tons of water and even tens of thousands of tons of water, and because the number of stages is too large, the filtration effect is difficult to ensure. Even clean tap water passes through pipelines of several kilometers, which is well known as secondary pollution of tap water. The secondary pollution mainly comprises galvanized pipe pollution, rusting of water pipes and taps, garbage pollution of high-rise water tanks and the like, and the secondary pollution becomes a hidden danger of safe drinking of tap water.

Membrane separation, which has been rapidly developed in recent decades, is a novel separation technology, and compared with the conventional treatment process, the membrane separation technology has the advantages of high efficiency, low energy consumption, high automation degree and the like in the aspect of water treatment, and has attracted extensive attention of researchers in recent years. The membrane separation technology is characterized in that a certain form of pressure is applied to the outside, so that the water to be treated flows to the other side through one side of a membrane surface, and treatment substances such as bacteria, proteins and the like contained in the water are intercepted by the membrane surface, so that the water purification treatment is realized.

In the water purifier, a core component playing a purifying role is a porous filtering element, and a traditional filter element is independently arranged according to different functions and materials; according to the filter flux demand of difference, need set up a plurality of filter cores under the general condition, consequently occupation space is great, and the connection between the filter core also has the installation inconvenient to and the access point leads to appearing leaking the scheduling problem frequently.
