Description
Technical field
The present invention relates to medical sewage, sanitary sewage disposal technical field, more particularly to a kind of wastewater disinfection powder, making side
Method and its application method.
Background technology
Produce sanitary sewage per capita according to statistics 100-150L/ days.Pollutant in sanitary sewage mainly has detergent, rubbish
Contain substantial amounts of organic matter in rubbish, excrement, sanitary sewage, be that the presence such as pathogen, virus is provided convenience, general sanitary sewage
In containing bacillus up to 100,000-100 ten thousand/ml, ten thousand/ml of streptococcus 1000-10, in addition with various pathogenic bacteria.In sewage
Common pathogen has：Pathogenic bacteria, enterovirus and worm egg.Medical sewage with the area where hospital, scale,
Property is different and composition difference is larger；Often containing pathogen, organic matter, inorganic matter, radiometal ion etc. in hospital sewage；Not
Cause of disease bacterial content through processing reaches 100,000,000/ml.With increasingly shortage and the mankind increasingly the weighing to health of water pollution
Processing depending on, sanitary sewage, medical sewage is more and more important.
Traditional sanitary sewage and medical sewage sterilization method has following several：Liquid chlorine disinfection method, disinfection by chlorine dioxide method,
Hypochlorite disinfectant's method, ozone disinfection, ultraviolet sterilization.Liquid chlorine disinfection method, using liquefied chlorine gas, chlorine is poisonous in itself
Property, the accessory substance with carcinogenic property is introduced in disinfecting process, and need special storage device, it is impossible to kill hidden spore
Worm；Disinfection by chlorine dioxide method uses chlorine dioxide, and chlorine dioxide is unstable in itself, easily occurs blast, the risk of transport storage
Greatly, it is the same with chlorine that carcinogen can be introduced in disinfecting process；Hypochlorite disinfectant's method is, it is necessary to which special sodium hypochlorite is produced
Device, and Disinfection Effect is poor, can also produce carcinogen；Ultraviolet sterilization, is influenceed by the limpid degree of water body, research
Show that ultraviolet is only so that part pathogenic bacteria enter resting state, all pathogenic bacteria are not killed completely；Ozone disinfection is smelly
The reaction such as organic matter in oxygen and sewage, there is very strong disinfecting power, but ozone is unstable, no continuous disinfection ability, and ozone
, can introducing portion poisonous and harmful substance in disinfecting process.Traditional sanitary sewage and the sterilization method of medical sewage, only have
Disinfection efficacy, it is impossible to effectively reduce COD, BOD in water, it is incompetent to the suspension in water, heavy metal ion, radioactive substance
For power, sewage disposal needs just use after grid filtration, fermentation, precipitation, flotation, in-convenience in use.

D, wastewater disinfection powder is made, sealing is sealed up for safekeeping.
A kind of application method of wastewater disinfection powder, the application method is as follows：
A, wastewater disinfection powder 6-12g in this case is taken, be added in 500ml-1000ml pure water, stir and evenly mix, be sterilized water
Liquid；
B, the sterilization aqueous obtained in A added into 1t sewage, disinfecting time 2-24h.
Potassium hydrogen persulfate, calper calcium peroxide meet water after, it is continual generation nascent state atom active oxygen, with acidic components,
Chain reaction occurs for iron chloride, magnesium sulfate, produces a variety of high mars free radicals, superoxide radical, sulphuric acid free radical, hydroxyl free
Base, hydrogen peroxide and micro hypochlorous acid etc., the oxidation-reduction potential of wherein sulphuric acid free radical are up to 2.5-3.1V, hydroxyl free
The oxidation-reduction potential of base is up to 2.8V, much larger than the oxidation-reduction potential of liquid chlorine, chlorine dioxide and ozone；A variety of high activities are certainly
Make it that sterilization spectrum is wide by the presence of base, the free radical of part high redox potential causes Disinfection Effect good, can kill virus,
Fungi, bacillus, and pathogenic, teratogenesis, carcinogenic material will not be produced, sterilize safe and efficient.
Iron chloride can generate cotton-shaped many micropores with hydrogen sulfide, phosphate, arsenate and alkali substance reaction in water and sink

Compound, heavy metal and can sterilize, dephosphorization, reduce the index such as COD, BOD of water outlet.
Sodium acid carbonate, can be with the acid-base value of regulating water quality as nertralizer.
Chitosan is a kind of positively charged natural polymerses, by electrostatic attraction, can effectively go water removal
The organic matter such as middle heavy metal ion and Starch Protein, forms precipitation, reduces COD；Chitosan is natural high molecular polymerization
Thing, source is wide, and flocculating effect is good, does not bring secondary pollution.
Starch xanthate is a kind of efficient flocculant, with oil removing turbidity removal, reduction, reduces COD function；And will not band
Carry out secondary pollution.
Nano titanium dioxide, under the ultraviolet of natural light, to bacillus subtilis black variety gemma, Pseudomonas aeruginosa, big
Enterobacteria, gold-coloured staphylococci, salmonella, tooth branch bacterium and aspergillus have extremely strong killing effect；Disappear as one kind is long-acting
Toxic agent is present in water.
Mono-fatty acid glyceride can disperse larger organic detritus as surfactant, be easy to flocculant to play work
With.
Stabilizer can cause wastewater disinfection powder to have stable characteristic, conveniently transport, store and use.
Above-mentioned technical proposal is employed, the beneficial effects of the invention are as follows：Persistently produced after the wastewater disinfection agent dissolving of this case
A variety of high mars free radicals, superoxide radical, sulphuric acid free radical, hydroxyl radical free radical, hydrogen peroxide and micro hypochlorous acid are a variety of
Free radical combined disinfection, the advantage of highly effective and safe good with wide sterilization spectrum effect；Iron chloride, chitosan, starch xanthate three
Plant flocculant to use cooperatively, poisonous and hazardous heavy metal ion, radioactive substance and the organic matter in water can be adsorbed, formed
COD, BOD of precipitation, effectively reduction water body, and secondary pollution is not introduced；Nano titanium dioxide, can be with long-acting killing water
Various bacteria, fungi, and it is nontoxic；, can be without lattice during processing sewage because this product has fabulous flocculating effect
The processes such as grid filtering, fermentation, precipitation, flotation, it is easy to use.
