Description
Technical field
The utility model relates to a kind of water technology, and especially a kind of water treatment technology, specifically a kind of tap water is without chlorine disinfectant disinfection system.
Background technology
Disinfection technology is widely used in water treatment field, is one of important means of water technology.Existing disinfection technology mainly contains following a few class:
1. there is chlorine disinfectant sterilization.As: chlorine, clorox, dioxide peroxide etc.;
2. ultraviolet ray sterilization bactericidal;
3. ozone disinfecting-sterilizing;
4. hydrogen peroxide disinfection;
5. other disinfection modes: photocatalysis technology, electric field disinfection technology, (copper silver) alloy disinfection technology etc.
The subject matter that above-mentioned disinfection technology exists is:
1. there is chlorine disinfectant sterilization technology.
This is a kind of technology being widely used in city tap-water disinfection.Wherein:
Disinfection by chlorine sterilization can generate the carcinogenic substances such as haloform.And chlorine inherently has poison gas, storing or using all needs strict control.
Hypochlorite disinfectant's sterilization generally adopts hydrochloric acid (HCl) to add sodium chlorate (Na
2clO) reaction forms.Because hydrochloric acid belongs to hazardous substance and precursor chemicals, the buying in market and shipping storage all require higher.
Disinfection by chlorine dioxide sterilization generally by electrolytic saltwater and obtaining, efficiency is lower but consume energy very large.
Several above have chlorine disinfectant bactericidal assay all can produce the meta-bolites endangered human body or physical environment, and in its final product, chlorion endangers very large in industrial production, and it can to the generation such as pipeline, equipment corrosive nature.Because of the stability of its chemical structure, chlorion is difficult to be removed
2. ultraviolet ray sterilization bactericidal technology.
Ultraviolet ray sterilization bactericidal utilizes the DNA(thymus nucleic acid in suitable wavelength destroy microorganisms cell) and RNA(Yeast Nucleic Acid) molecular structure and play sterilization and in use have following shortcoming:
(1) without Continuous sterilization ability, can be able to again pollute after ultraviolet disappears.
(2) in turbidity and water, suspended substance has considerable influence to ultraviolet ray sterilization bactericidal, reduces sterilization effect.
(3) the easy fouling of UV-lamp sleeve pipe, affects appearing and sterilization effect of ultraviolet.
(4) relative energy consumption is larger.
3. ozone sterilizing disappears bacterium
The ozone sterilizing bacterium that disappears utilizes its strong oxidizing property to carry out destruction to bacterium, cell walls and inner DNA, RNA to play killing action, in use has following shortcoming:
(1). the main Problems existing of ozone disinfecting-sterilizing is that production unit (spark-discharge method) is huge, flow process is complicated, needs higher operation and management level.Ozone generation rate lower (1 ~ 2%), power consumption is large, and building equipment investment is comparatively large, cost is very high, is not suitable for the disinfection technique that the water yield is larger.
(2) ozone is a kind of gas of instability, easily decomposes in water, adopts separately ozone disinfecting-sterilizing to be difficult to the effect ensureing to continue.
(3) there are some researches show that ozone and organism reaction can generate unsaturated aldehydes, the toxic substances such as dual oxide compound, can produce carinogenicity product: main degradation products has organism in containing a small amount of bromide: methenyl bromide, acetonitrile methyl chloride, 1-1 bis-bromoketone etc.Inorganic nature product has bromate, hypobromous acid etc.Wherein will importantly bromate, its maximum acceptable concentration is extremely low, and USS is 0.01mg/L.
(4) chlorination or chloramines can generate trichloronitromethane respectively and mauguinite all has larger harm again after ozonize.
4. hydrogen peroxide disinfection
The hydrogen peroxide virus killing bacterium that disappears also is utilize its strong oxidizing property to play sterilization, and its shortcoming is:
(1). hydrogen peroxide (H
2-O
2) human body gene (DNA) damage and transgenation can be caused, be related closely with various pathology.
(2). hydrogen peroxide can cause the animal such as mouse and rabbit carcinogenic, thus may possess danger to the mankind.
(3). hydrogen peroxide may accelerate mankind aging's process, itself and senile dementia especially presenile dementia generation and develop closely related, as strong oxidizer by antioxidant in consume body, make resistance of oxidation low, resistibility declines and causes various disease further.
(4). hydrogen peroxide may cause or increase the weight of the eye diseases such as cataract, can cause injury of lung by respiratory tract, and multiple-contact can cause human hair to bleach, xanthoderma etc.
(5). small molecules hydrogen peroxide per os is taken in and is easy to enter cells in vivo and tissue, can cause the numerous disease relevant to free radical by freedom of entry radical reaction chain.
5. other disinfection modes-
---
Limitation due to himself: the factors such as too low in efficiency, energy consumption is too large, investment is too high and stability is inadequate can not be accepted extensively by water treatment market.
