Water purification method and device

Abstract

A process for cleaning water includes such steps as high-temp calcining of shell (calcium carbonate) to obtain calcium oxide powder, mixing it with natural seal salt, concentrating electrolysis to educe out crystal with weak-alkaline positive ions, grinding to become easily soluble powder, and adding it to the water to be cleaned to deposit the suspended particles.

Description

technical field [0001] The invention relates to a method and device for water purification, in particular to a method and device for drinking water purification. Background technique [0002] With the development of industry, the natural ecology has been destroyed, and the toxin residue and infiltration that may be produced in transportation and storage have caused water pollution, which has seriously threatened the safety of human drinking water. Therefore, drinking water usually needs to be purified before it can be used. Drink with peace of mind. As far as the current water purification methods are concerned, they generally include: chemical agents (iodine, chlorine, bromine), ozone, ultraviolet rays, reverse osmosis, particle filtration... However, the above water purification methods actually have the following deficiencies at: [0003] 1. As far as ozone and ultraviolet water purification methods are concerned, although ozone or ultraviolet rays can achieve the effec...

AI Technical Summary

Problems solved by technology

[0003] 1. As far as ozone and ultraviolet water purification methods are concerned, although ozone or ultraviolet rays can achieve the effect of sterilization, they cannot effectively remove pollutants such as acidic suspended particles in water

[0004] 2. In terms of reverse osmosis and particle filtration water purification methods, although the filter element can be used to screen out fine suspended particles in the water to achieve water purification effect, the user not only needs to hire someone to install expensive and complicated water purification equipment, but also Water filter consumables must be replaced regularly, and once these water filter consumables lose their filtering effect, they cannot be recycled and reused, resulting in waste of resources

[0005] Furthermore, in terms of the current "pre-chlorination" water purification process for tap water, it uses a large amount of chlorine for disinfection, but the tap water after adding a large amount of chlorine is very likely to produce carcinogenic "trihalomethanes" (trihalomethanes), make the building's water storage tank a source of pollution

[0006] It is known that alkaline drinking water containing a lot of calcium ions is good for health, but the above-mentioned water purification methods are only pure water, which cannot make the water alkaline and increase the calcium ions in the water, which is a pity
