Technical field
The present invention relates to a kind of disinfectant, and in particular to a kind of Hospital Sewage Treatment Potassium Monopersulfate composite disinfecting
Agent.
Background technology
At present, the processing of sewage caused by hospital still more uses the disinfectant based on effective chlorine class to carry out disinfection place
Reason, but chlorine-containing disinfectant can produce many accessory substances during use, such as chlorohydrocarbon, chloracetic acid, chloroacetonitrile, chlorine
Ketone etc., and the investigation of epidemiology shows, these accessory substances and urinary system canceration, human primary gastrointestinal cancers, pregnant woman's miscarriage, other breedings and
Development problem is closely related, such as the chlorine dioxide as some disinfectant main components, though its zoopery belongs to nontoxic level,
The chlorine dioxide and its accessory substance of high concentration may have potentially hazardous, the standardization of its industry and preparation side to health
The rationalization of method, the differentiation standard of active ingredient and storing safety issue etc. still have to be solved.
Few hospitals handle hospital sewage using peroxide disinfectant, although peroxide disinfectant is in the presence of many excellent
Point, as Peracetic acid, hydrogen peroxide are respectively provided with good killing effect to bacterial propagule, virus, fungi and gemma, having can
Operational height, has a broad antifungal spectrum (even if heterogeneous organic matter being present), without sustained toxicity and genetoxic, not by the shadow of solution ph
Ring, the advantages that time of contact is short, suitable for one-level secondary waste water effluent；Ozone can kill various microorganisms, including leather orchid
Family name's positive and negative bacteria, gemma, virus, fungi or even parasite.But there is also problems with：
(1) the phase interaction between the higher and different peroxide compound of dosage of the hydrogen peroxide in simple use
Still treat further to study with the toxic action after mechanism, and compatibility；
(2) disinfecting power of ozone can be with pH value, temperature, RH, additive (surfactant and carbohydrate etc.) and cell
The change of the quantity of surrounding organic matter and change, some DBPs (DBPs) can be produced during ozonization, such as saturation
Aldehydes, organic acid, epoxide, bromo compound etc.；
(3) although more preferable than using chlorine and chlorine dioxide using Disinfection Effect during peroxide disinfectant, it is pacified
Full property evaluation still needs further to be studied.
CN104719336A discloses a kind of low-corrosiveness potassium peroxymonosulfate disinfectant, the disinfectant of the formula
The Main Ingredients and Appearance for playing sterilization is Potassium Monopersulfate, due to the characteristic of Potassium Monopersulfate in itself so that formula
More auxiliary ingredients are needed to can be only achieved the purpose effectively sterilized, the problem of this also results in Formulation Ingredients complicated, high expensive.
As can be seen here, effective chlorine class and peroxide disinfectant respectively have quality, this containing a large amount of true in processing hospital sewage
Bacterium, bacterium, the water body of virus and gemma, need a kind of quick, wide spectrum and the new disinfectant for being capable of Continuous sterilization badly.
The content of the invention
In view of the shortcomings of the prior art, it is an object of the invention to provide a kind of Hospital Sewage Treatment to be answered with Potassium Monopersulfate
Close disinfectant, there is the characteristics of sterilizing power is strong, available chlorine content is low, react generation peroxy acid have concurrently effective chlorine class,
The advantages of two class disinfectant of peroxide, so as to avoid producing three cause things because available chlorine content is high, and used merely
High concentration requirement during oxygen acid, has saved cost, has reduced potential safety hazard.
Hospital Sewage Treatment of the present invention Potassium Monopersulfate composite disinfectant, by the original of following mass percent
Material is made：
Preferably, it is made up of the raw material of following mass percent：
Wherein：
The mole dosage of the malic acid is 2 times of the difference of Potassium Monopersulfate and sodium chloride mole dosage；
The preparation method of the disinfectant is as follows：The raw material of above proportional quantity is molten with 20-30g/L mass concentration proportioning
In Xie Yushui, and wavelength is used as 240-280nm, radiation intensity 90uW/cm2Ultra violet lamp 5min, obtain product.
In the present invention：
The non-oxychloride type activating component that Potassium Monopersulfate belongs in disinfectant, can discharge including small point after soluble in water
Various active species including sub- free radical, nascent oxygen, the permeability of cell membrane barrier of microorganism can be destroyed, can be aoxidized
Pathogen so that bacterium protein denaturation solidification, so as to kill pathogenic microorganism；Simultaneous sodium chloride composition in disinfectant
It can cause to produce free chloro ion in solution after decomposition, potentiometric titrations caused by potassium hydrogen persulfate decomposition can pass through free radical
The acting activating chlorion of chain type, chlorine radical and chlorine molecular radical are produced, the oxidation generation material such as chlorine and hypochlorous acid, is passed through
Destroy thallus DNA and play a part of disinfection, while be advantageous to the removal to ammonia nitrogen.
Potassium Monopersulfate has a very strong oxidisability in itself, but it is dissolved in after water that easily quick release goes out oxygen, and kills
Bacterium effect is weaker, therefore Potassium Monopersulfate can not be merely is used to sterilize, it is necessary to be equipped with other compositions, such as chlorion, organic
Acid；The sulphuric acid free radical that Potassium Monopersulfate discharges can aoxidize chlorion and organic acid, but the concentration of sulphuric acid free radical and its
Oxidizing potential affects reaction, and it is primary that more sulphuric acid free radicals, which how are more quickly formed, and effectively play its oxidisability
Problem.In metal ion such as Co2+, Fe2+And sulphuric acid free radical can be formed under the catalysis of ultraviolet faster and more, so as to with
Chlorion, organic acid reaction generation hypochlorous acid and peroxy acid in side, and play sterilization is hypochlorous acid and mistake
Oxygen acid.The effect of ultraviolet is that electron provides certain potential energy so that HSO5 -Preferably take off H+, generation-SO5 -, so as to shape
Into-SO5-SO5-, and then produce sulphuric acid free radical.
Malic acid is added in system and on the one hand plays a part of adjusting pH as a kind of organic acid, and prior work
With being that the organic acid is easy to be oxidized to peroxy acid by Potassium Monopersulfate, peroxy acid is by destroying the sulfydryl of thalline, disulfide bond rises
To the effect of disinfection.
Because original chlorion and organic acid can play a part of disinfection, but actual use in the very first time
In, organic matter, inorganic matter such as ammonia nitrogen in water body etc. can all consume oxidant, and in order to keep lasting sterilizing ability, spy adds
Sodium dichloro cyanurate, it is characterized in the balance of the aqueous solution persistently producing hypochlorous acid with hypochlorous reduction.
The present invention makes full use of the strong oxidizing property of Potassium Monopersulfate, is effectively played in the form of catalyst or ultraviolet catalytic
The strong oxidizing property of Potassium Monopersulfate, hypochlorous acid and peroxy acid are generated, form Inorganic whisker disinfectant, reach high-efficiency broad spectrum
The effect of disinfection.The problem of in view of secondary pollution, the present invention do not use Co2+、Fe2+As catalyst, but select
The mode of ultraviolet catalytic is selected.
Because use environment is different, the auxiliary element of inventive formulation have selected following 3 kinds：Citric acid, sodium metasilicate, dichloro
Sodium isocyanurate, if the water body organism of sewage, inorganic matter etc. need the debris for consuming oxidant less, it is contemplated that as far as possible
Accessory substance is reduced, then should select citric acid and sodium metasilicate；If water foreign is more, persistently killing for disinfectant should be considered
Bacterium ability, it should select sodium dichloro cyanurate.
In summary, the present invention has advantages below：
