Description

The super reverse osmosis water purifier in town and country
One, technical field
The utility model relates to the reverse osmosis water purifying plant, particularly the manufacturing field of the water purifier of the tap water that uses for town-dweller-rural-family.
Two, background technology
Since reform and opening-up, environmental pollution problems is increasingly serious.The seriously polluted life that is threatening the mankind of modern society's water resources; United Nations's health organization gives a warning to the whole world: " 21 century; water resources crisis will be the human fact that at first will face ", " whole world has at least people more than 50,000 to die from because of drinking the various diseases that polluted water causes every day." scientist reminds us: if or else we note the maintenance to water resources, will occur---" water grows on trees on the earth, but one can not be drunk! "
The pollution day by day of water resources, particularly serious to the influence in rural area.Basically be peasant's digging well to get water with good conditionsi, unqualified is just fetched water in the river and the mountains and rivers and is drunk, and at present the whole nation more than 90% the river and underground water is polluted even severe contamination, its pollution is loathsome especially, especially underground water and tap water ferrimanganic, suspended substance, the colloid thing, toxic byproduct, agricultural chemicals, bacterium, silt, iron rust, the solid impurity pollution hazard, organic chemicals, agricultural chemicals, chemical fertilizer, acid cancer thing, heavy metal and metal ion, trichloromethane (rural households that relate to are greatly about more than 5.6 thousand ten thousand), even there is well that water is arranged, also severe overweight, can't drink, threaten human healthy.The condition of similar city tap-water is not used in general small towns, and directly with underground water or the face of land natural stream networks source as tap water, its present situation is rural households' drinking water pollution, severe overweight to small towns population; The small towns tap water partly exceeds standard, and do not reach People's Republic of China's new " drinking water sanitary standard ", and the present situation of above-mentioned pollution has constituted the very big threat to the town and country personnel health.
Now known on the market water purifier product design simple structure, technology content is comparatively low, mainly be based on small towns the exceed standard rough purification of groundwater source and the purification again of tap water, the purpose that reaches general tap water designs, and can not solve cities and towns and people in the countryside water source and reach the purpose that People's Republic of China's new " drinking water sanitary standard " becomes pure water after purifying.As: Chinese patent literature disclose a kind of " the super active water water making machine in town and country " (ZL200820063753.7) and " inorganic nutrients water purifier " (CN87216207), the two all is the water source with the tap water, adopts the purification of precision Filter element and resin cation (R.C.), the filtration of active carbon-point, active water generator filtration, the senior filter element filtering of accurate activated carbon to be treated as direct drinking water.
