Abstract
The invention discloses an antibacterial ceramic particle for water treatment and a using method. The antibacterial ceramic particle for water treatment is composed of 80%-99.99% by weight of a matrix material and 0.01%-20% by weight of an antibacterial agent. According to the invention, by adopting a novel antibacterial water-purifying technical thought, and an antibacterial particle which is efficient and lasting in antibacterial and bacteriostatic effect is provided; the antibacterial particle can be widely added into water purifying materials, such as active carbon, a small connector, a pipeline machine, barreled water and bottled water, a component and a terminal drinking-water product to achieve antibacterial treatment effect, so that a microbial secondary pollution problem of water treatment product is widely solved.
Description
Technical field
The present invention relates to water-treatment technology field, specifically, relate to anti-bacteria ceramic particle and using method for a kind of water treatment.
Background technology
In recent years, due to environmental pollution, particularly water is seriously polluted, and water purification Industry Quick Development estimates that the market scale of water purification industry will reach 4,000 hundred million yuan in the five-year.Yet the mind great trouble that water purifier discharge water colony number exceeds standard, secondary pollution problem is industry always, quick-fried light excessively for a long time in the media, and also up to the present, this problem is not also solved always preferably.
For example, water after reverse osmosis machine purifying treatment is sterile pure water, yet the pressure pot of reverse osmosis membrane assembly postposition and T33 assembly through moving for a long time under wet condition, very easily grow a large amount of microorganisms, often easily cause water outlet microbe colony number greatly to exceed standard.And for example, the little UNICOM water storage device of normal and reverse osmosis machine, ultrafilter coupling, inwall tends to tongue green for a long time (microorganism amount reproduction) in use for some time, and human consumer's health has been brought to huge potential risk.
For fear of the secondary pollution problems such as microbial contamination of water purifier, the method for current normal employing is to use the disinfection of powerful and expensive sterilizing agent to filter material, but these methods all exist many drawbacks.Sterilizing agent often can destroy organic film material and may cause corrosion to plastic assembly, and residual sterilizing agent also is likely given to purify waste water and polluted; Backwash operation is bothersome water wasting often, also need drive by external force, and the filtering material of not all purifier is all applicable to backwash operation.The current method also existing is to adopt UV-device, ozone equipment etc. to carry out degerming, and the obstacle that these devices are expensive, security is low, used is in a large number numerous.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, adopt the thinking of novel antibacterial water purification technology, a kind of antibacterial granule efficient, durable antibiotic fungistatic effect that has is provided, can extensively make an addition in proportion in the water-purifying materials such as gac, little UNICOM, pipeline machine, bottled water, bottled water, assembly and terminal drinking-water product, reach antimicrobial treatment effect, extensively solve water-treated prod microorganism secondary pollution problem.
To achieve these goals, the present invention adopts following technical scheme:
A water treatment anti-bacteria ceramic particle, is comprised of body material and antiseptic-germicide, and its weight percentage is respectively 80-99.99%, 0.01%-20%.
