Central water purifier

Abstract

The invention relates to a central water purifier which comprises a pressure bearing container, a negative electrode, a positive electrode and an electrolysis power source. The negative electrode and the positive electrode are in a pair, the pressure bearing container comprises a metal barrel arranged vertically and insulating sealed end caps at two ends, an insulating spacer bush is arranged in the pressure bearing container, a plurality of water permeable holes are formed in the middle of the insulating spacer bush, the negative electrode is arranged at the bottom of the insulating spacer bush, a first water-permeable membrane and a second water-permeable membrane sequentially wrap the insulating spacer bush outwards, a physical adsorption filter core is filled between the first water-permeable membrane and the second water-permeable membrane, a sewage outlet is arranged on the end cap at the top of the metal barrel, a water inlet is arranged on the end cap at the bottom of the metal barrel, a water outlet is arranged between the second water-permeable membrane and the metal barrel, and the metal barrel is electrically connected with the negative electrode. The central water purifier can eliminate pollution by microorganisms and viral bacteria of a household drinking water pipeline system and can improve and lower hardness of water.

Description

technical field [0001] The invention relates to a central water purifier, in particular to a water quality purification device installed at the general water inlet end of small and medium-sized users (such as families, villas, etc.), and belongs to the technical field of advanced treatment of drinking water quality. Background technique [0002] At present, the water environment is worsening and deteriorating, but most waterworks at home and abroad still use the outdated process of sedimentation, filtration, and chlorine disinfection to simply process river water or groundwater. However, in the face of the rampant flooding of industrial sewage, agricultural sewage and domestic sewage into domestic water sources and causing primary pollution of water sources, waterworks have been overwhelmed and unable to do anything. [0003] Chlorination disinfection is a tap water disinfection technology that has been used in my country for many years and is still widely used. It plays a k...

Problems solved by technology

The main problem is that the softened water can only be used for washing, not for drinking

Because ion exchange removes calcium and magnesium ions in water, it releases a large amount of sodium ions into the water, which is not healthy

Moreover, the water softener needs to be backwashed frequently with salt (sodium chloride), which is time-consuming, laborious and expensive
