Description
Technical field
The present invention relates to a kind of device that domestic water is purified, belong to water-treatment technology field.
Background technology
Water pollutions and people's life level improve and have expedited the emergence of domestic water purification industry.But the product homogeneity of domestic water cleaner is serious so far, product quality is very different, and quality problems emerge in an endless stream.Though the Ministry of Health of China spot-check supervision every year, the water purifier substandard product of bulletin over the years and producer's cumulative year after year on the contrary.2010, two kinds of famous brand ultra-filtration water purifiers were circulated a notice of because sampling observation bacterium exceeds standard; Within 2011, Ministry of Health's bulletin unacceptable product is increased to 14.Technological innovation has become the primary bottleneck of restriction drink water purifier industry development.How to guarantee being perfectly safe of drinking water quality, and water saving, environmental protection, health, become government, focus that society, the common people pay close attention to jointly.
The situation making a general survey of existing domestic water cleaner (hereinafter referred to as water purifier) technology and product is as follows:
1, the existing water purifier technology being handling object with " water,tap " has been difficult to adapt to because ambient water pollutes aggravation, city for the deterioration that tap water feeding secondary pollutes, tap water chlorination is harmful to malicious secondary thing etc. source water quality.In recent years, natural disaster is continuous, and water pollutions Emergent health event takes place frequently, and requires that water purifier should be designed with certain elastic load intensive treatment ability, to ensure still can to ensure that effluent quality is up to standard in tap water Emergent health event emergent period.But existing commercially available water purifier cannot meet so high requirement at all.
2, the typical process structure of the existing water purifier in market is: (PP is cotton in 1. pre-treatment, pottery, stainless steel filtering net etc., be mainly used in the suspended particle in the water of removal source, colloidalmaterial) → 2. intermediate treatment (all adopt granulated carbon-sintered carbon, for eliminating the unusual smell, reduce colourity, absorption chlorine residue, intercept larger molecular organics and adsorb small organic molecule, Adsorption heavy metal ion and degerming etc.) → 3. membrane filtration (the ultra-filtration membrane that filtering accuracy is 0.1 ~ 0.01 micron, for suspended substances all in filtering water, colloid, microorganism and virus, and part larger molecular organics, filtering accuracy is the nanofiltration membrane of nanometer, is mainly used in removing hardness components and the evaporation of residual materials such as haloform intermediate, peculiar smell, colourity, agricultural chemicals, synthetic detergent, dissolved organic matter, Ca, reverse osmosis membrane) → 4. aftertreatment (active carbon loading silver etc. are mainly and improve mouthfeel, antibacterial etc.).The process structure Problems existing of above-mentioned existing water purifier has:
2.1 pre-treatments are middle-chain-activated carbon especially, plays the vital role formed a connecting link, but very easily loses efficacy by Premature saturations such as bacterial contaminations, needs professional person regularly to make house calls and frequently changes, too increase the probability that joint leaks simultaneously.
2.2 can not effectively work due to prime pre-treatment, have greatly increased the weight of the load of rear class ultrafiltration (nanofiltration, reverse osmosis) processing unit, so that its design capacity has to strengthen, complete machine cost is corresponding increase also.
2.3 because of before, during and after the load distribution of work for the treatment of at different levels unreasonable, need frequent replacing prime filter core, existing water purifier is caused to be multistage packaging assembly, cannot be integrated in a reactor, the ratio of performance to price is extremely low, also cause rear class membrane filter unit earlier breakage to lose efficacy, machine life is short simultaneously, and this is also another reason that water purifier really can not become electrical household appliance.
3, electrochemical water treating method is based on the redox reaction of electrochemical electrolysis process, utilize electrode reaction and correlated process thereof, by directly and the comprehensive action such as indirectly redox, cohesion flocculation, absorption degradation and collaborative conversion, to Organic substance in water, heavy metal, nitrate, colloidal solid thing, bacterium, colourity, smell the pollutents such as taste there is excellent removal effect.But electrochemical water treatment technology is difficult to be applied in domestic water purifying processor so far.This is because for life water purifier, it is only number of seconds magnitude that water pollutant stops duration of contact in water purifier, because duration of contact is too short, therefore has little time abundant reaction at all.At present compared with the KDF(Antimicrobial device of widespread use) water technology is electrochemistry a kind of reasonable trial in life domestic water purifying processor.But the specific surface area of KDF is little, and price is more expensive, normally combinationally uses with activated carbon; And the spontaneous galvanic cell potential difference of KDF is too low, redox effect is not enough.
