Description
Technical field
The present invention relates to water correction plant, particularly for the manufacture field of the water purifier of the tap water of town-dweller-rural-family and enterprises and institutions.
Background technology
Along with the continuous propelling of world industry, the problem of water pollutions is increasingly serious.The seriously polluted life that threaten the mankind of water resources; United Nations's health organization gives a warning to the whole world: " 21 century; water resources crisis by be the mankind first will faced by the fact ", " the various diseases that the whole world has at least people more than 50,000 to die to cause because drinking polluted water every day." scientist reminds us: if or else we note, to the maintenance of water resources, just there will be---" water, the earth grows on trees, but one can not be drunk! " World Health Organization's investigation points out; human diseases 80% is relevant with water, and the main sterilization method of tap water is chlorination sterilization, although can a large amount of bacterium be removed; also there is objectionable impurities; the heavy metal especially in water, the compositions such as chlorine molecule and nitrite, while course of conveying, water tower storage etc. all can cause secondary pollution to a certain degree; although by water boil; also cannot remove the objectionable impuritiess such as the heavy metal in water, the Excess free enthalpy of these materials, can cause great harm to human body.Particularly serious on the impact in rural area, rural potable water sanitary condition urgently improves, the water source of China's domestic drinking water in rural areas is mainly based on underground water, the population of Drinking Water accounts for 74.87%, the population drinking the surface water accounts for 25.13%, substantially be peasant household with good conditionsi digging well to get water, unqualified is just at rivers, lake, reservoir, in gully, directly water intaking is drunk, these underground water typical contamination, even severe overweight, especially underground water iron, manganese, alkali, suspended substance, colloid substances, toxic byproduct, agricultural chemicals, bacterium, silt, iron rust, solid impurity pollution hazard, even there is well to have water, also severe overweight, cannot drink, threaten the healthy of the mankind.General small towns does not use the condition of similar city tap-water, small towns population is directly using underground water or earth's surface natural stream networks as the source of tap water, its present situation is, the drinking water pollution in rural area, severe overweight, do not reach People's Republic of China's " drinking water sanitary standard ", and the present situation of above-mentioned pollution constitutes the great threat to town and country personnel health.
Now on the market known water purifier product mainly based on purifying again city tap-water, the object reaching Drinking Water designs, but it is relatively simple on design structure, technology content is comparatively low, especially the hierarchical back flush of filter core has been become to a technical bottleneck of this series products, current most manufacturers mainly adopts the treatment process of manual cleaning frequently and more renew cartridge, the object that water purifier becomes hierarchical back flush blowdown in course of normal operation can not be solved, as: Chinese patent literature discloses one " purifier of the self-stip that can be in operation " (CN87216207), take tap water as water source, adopt differential control discharge, concora crush gac filtration, nanofiltration core filtration treatment becomes Drinking Water.
