Abstract
The invention discloses a kind of drinking device sterilization dechlorination environmental protection water process, comprise the steps：(1) running water is handled into (2) ultrafiltration membrance filter with activated carbon.Drinking device of the present invention sterilization dechlorination environmental protection water process, " secondary pollution " that can solve the problems, such as drinking purpose of tap water inconvenience and running water damage to human body；Activated carbon has heavy metal, the suction-operated of chlorion and water quality are decolourized and clarification, various materials that can be larger effectively in adsorptive liquid, impurity；Tourmaline processing also add the bioactivity of water, and having improves the characteristics such as body physiological function；The present invention can realize permanently effective suppression and kill bacterium, remove removing heavy metals, chlorion, prevent drinking device and secondary pollution is produced because of bacteria breed, increase the service life.
Description
Technical field
The present invention relates to water-treatment technology field, more particularly to drinking device sterilization dechlorination environmental protection water process.
Background technology
Running water refers to purify by water treatment plants, sterilize after produce meet being given birth to for people for respective standard
The living, water of production and application.Domestic water mainly draws rivers and lakes and underground water by the water intake pumping station of water factory, surface water, by
Waterworks according to《National Drinking Water related sanitary standard》, by the processing for precipitating, sterilizing, the technological process such as filtering,
Each user is transported to finally by Energy Saving Measures of Pumping Station.
The life of running water and people are closely bound up, and the water quality of running water and people's is healthy in close relations.China's water quality
Standard also has a certain distance than international standard at present.Water supply security is faced with pollution of waterhead getting worse and feedwater quality at present
The dual-pressure that standard gradually steps up, this also just proposes higher requirement to advanced water treatment technology.
Waterworks generally use liquid chlorine or bleaching powder carry out sterilization processing to running water, cause to contain in running water
A certain amount of free chlorine.According to national drinking water standard, the content of water users end pipeline free chlorine must not be less than
0.05mg/L, but being somebody's turn to do " chlorine residue " can act on the organic substance in water, produce harmful chlorinated organics, such as chlorine
Imitative, dichloroethylene, carbon tetrachloride etc..It is therefore desirable to carry out dechlorination operation to running water, to eliminate the harm that " chlorine residue " is brought.
In running water preparation process and the water transfer pipe network of aging and the water tank of unmanned cleaning, inevitably cause from
" secondary pollution " of water, therefore the running water being sent into user family can not directly be drunk, usual people are simply by boiling water
It is boiled just directly to drink, and boil water and not only bother, and simply play a part of disinfection, it can not eliminate in running water
Heavy metal and various harmful substances.But the pollution getting worse of current water resource, especially heavy metal pollution and organic matter
Pollution, the injury that can not caused through treated running water to body is drunk for a long time.
Therefore, water safety is further ensured, for the health of people and the development of society, it is a kind of i.e. convenient to be badly in need of
Practicality, and drinking water treatment method capable of direct drinking.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of drinking device sterilization dechlorination environmental protection water process, this drink
" secondary pollution " that can solve the problems, such as drinking purpose of tap water inconvenience and running water with method for treating water damages to human body.
In order to solve the above technical problems, the present invention is achieved through the following technical solutions：
A kind of drinking device sterilization dechlorination environmental protection water process, comprises the steps：
(1) running water is handled with activated carbon；
(2) ultrafiltration membrance filter.
A kind of drinking device sterilization dechlorination environmental protection water process, comprises the steps：
(1) running water is handled with antibacterial active carbon；
(2) tourmaline is handled；
(3) ultrafiltration membrance filter.
The aperture of the milipore filter is 0.002-0.02 μm.
The particle diameter of the tourmaline is 10-100 mesh.
Tourmaline processing procedure adds tourmaline into running water, and antibacterial active carbon processing adds anti-into running water
Bacterium activated carbon.
The preparation method of the antibacterial active carbon is：2-5 parts by weight chitosans are added to 45-55 parts by weight, quality point
