Description
Technical field
The present invention relates to a kind of preparation method of the compound ion sieve structure filter core for drinking water treatment.
Background technology
Along with the development in modern industrial or agricultural and city, a large amount of trade effluent and sanitary sewage are not effectively addressed and are discharged, and cause most of rivers, lake, underground water to be polluted.All the time, town dweller is drinking public water supply mostly.But, continuous worsening due to water pollutions, the treatment process of major part waterworks is relatively simple, can not remove the harmful organic substance in water and bacterium completely, especially the secondary pollution of tap water water delivery reservoir, water distribution pipeline is the hotbed of bacterial growth, when water pipe uses more than one month, due to fungi and mould parasitism, pipe inner wall there will be sliding, sticky phenomenon, the tap water causing water factory to export again contaminated, makes people very difficult for drinking qualified tap water.
Gac is widely used in drinking water treatment process, serves vital role to the improvement of tap water mouthfeel and the removal of poisonous and harmful substances.The biocompatibility good due to gac and chemical compatibility, in water, microorganism is easy to breed on the gac of adsorb organic compound, cause the decline of charcoal absorption objectionable impurities ability, become the hotbed of microbial reproduction, and the ammonia in water can be converted into nitrite by microorganism in water, cause water Central Asia nitric acid content to increase, cause outlet water quality to degenerate.
Silver is namely known before 2000 as sterilant, and the anti-microbial effect of silver is relevant with the valent state of self, and this ability is successively decreased in the following order: Ag
3+>Ag
2+>Ag
+.Silver ions can attract the sulfydryl of bacterial body endoenzyme egg strongly, and combines rapidly, makes to think necessary enzyme loss of activity, causes bacterial death.Therefore many investigators attempt to come eliminate activity charcoal sterilizing ability difference and easy this defect of bacterial contamination with active carbon loading silver.The people such as Luo Yongyi (Luo Yongyi, Zhang Kerong, Zhang Yao, Deng. silver absorption behavior on the activated carbon and the research [J] of mechanism. environmental chemistry, 1995,14 (1): 1-5.) research shows: the argent in active carbon loading silver constantly can discharge micro silver ion in water, inhibit growing of bacterium to a certain extent, but not there is redox reaction on the activated carbon in silver, just be adsorbed on activated carbon surface by physical action, cause the galactic pole of activated carbon surface easily to run off, the effect of lasting sterilization can not be reached.
Summary of the invention
