Description
Technical field
The present invention relates to technical field of water purification, and in particular to a kind of water-purifying filter.
Background technology
With increased population, industry and expanding economy, the pollution getting worse that surface drainage is subject to, factory's blowdown, life
Sewage living makes national good water sources constantly reduce；Underground water pollution is more startling, and garbage loading embeading, septic tank, mining site are dirty
It contaminates, the ground down blow of factory so that the quality of groundwater in the whole nation nearly 60% is " poor ".Currently, China waterworks is still using biography
System treatment process, the most of pollutant that cannot be removed effectively, the organic and inorganic pollutant having been detected by water is
More than 2100 kinds.
For different types of pollutant, a variety of water-purifying materials have been developed, have been applied in the equipment such as water purifier.However it is existing
All there is the problems such as process range is narrow, of high cost or there are secondary pollution risks in some materials：If PP cottons in water only for suspending
The removal of the large particulate matters such as object, silt, iron rust, colloid, it is all helpless for bacterium, organic molecule etc.；Common activity
Charcoal can remove chlorine residue, pesticide residue, pigment etc., cannot effectively adsorb bacterium, calcium ions and magnesium ions etc.；RO (reverse osmosis) film can remove big
Partial metal ion, but the minerals beneficial to human body are had also been removed simultaneously, while cost is higher；KDF can effectively deal with
Chlorine residue in water and heavy metal, and inhibit the growth of microorganism in water, but the problem of there are still heavy metal secondary pollutions.
In actual use, it to achieve the effect that clean water source and reducing net water-purifying material biological pollution, generally adopts
With sodium hypochlorite irreversible destruction can be generated to water-purifying material, made to being carried out sterilizing, the Active Chlorine thus introduced
Water purification performance declines rapidly and can not be continuing with.Therefore, to extend the service life of water-purifying material, water inlet also needs after sterilization
Dechlorination processing is carried out, the requirement of 0.1ppm is less than with contents of residual chlorine in reaching into water, this generic operation obviously increases operating cost.
If the equipment with high desalinization water-purifying material with chlorine-resistant property can be prepared, Operating Complexity can be effectively reduced, is dropped
Low operating cost；Simultaneously because water inlet in chlorine residue presence, can effectively inhibit the quick breeding of bacterium, avoid film operational process
In biological pollution, not only be conducive to system stable operation, chemical cleaning number can also be reduced, further decrease system maintenance
Expense.
