Description
The present invention relates to sewage disposal technology, specifically a kind of compound disinfectant and preparation method.
Along with developing rapidly of industry and concentrating and expansion of urban population, problem of environmental pollution is serious day by day.City domestic sewage is that the life activity by the resident is produced, the excreta that is mainly life waste material and people pollutes, because it has the condition that is suitable for microbial reproduction, and contain a large amount of bacteriums and pathogene, have certain harmfulness, particularly in some coastal cities, sanitary sewage is constantly to ocean disposal, make the offshore sea waters be subjected to severe contamination, bring serious harm for economical production and people's lives.As pernicious bacteria in the untimely removing sewage, not only can influence city living environment quality, and the development in city brought have a strong impact on.These pollute main employing chemosterilant such as bactericide such as phenols, hypochlorous acid class at present, although single use disinfection force is strong to causing secondary pollution easily in the ocean, its residuals not only works the mischief to marine organisms, and human health is constituted a threat to.
The purpose of this invention is to provide that a kind of bactericidal effect is more excellent, the compound disinfectant of non-secondary pollution and preparation method.
Technical scheme of the present invention is: umber by volume, its composition is got 100 parts of rhizoma extracting liquids, 100～200 parts of iodophor solutions that contain available iodine 0.3%～0.5% add calcium hypochlorite 0.8 gram～2.0 grams that contain available chlorine 25%～30% by per 100 milliliters of rhizoma extracting liquids;
Its preparation method is:
1) preparation rhizoma extracting liquid: take by weighing 20～100 parts of the coptiss by weight, add 200～1000 parts of distilled water, container that described solution is housed in 60～80 ℃ of water bath processing 20～30 hours, is filtered to get filtrate 1; Filter residue adds 100～400 parts of distilled water, and little fire boiled 1.5～2 hours, filtered to get filtrate 2; Filter residue adds 100～400 parts of distilled water again, and little fire boiled 1.5～2 hours, filtered to get filtrate 3; Merging filtrate 1,2,3, the low-temperature reduced-pressure method for concentration is concentrated into 1/2～1/6 of merging filtrate, and making rhizoma extracting liquid is 100～200 parts; The thickening temperature of described low-temperature reduced-pressure method for concentration is 40～60 ℃, and pressure is 700～760 millimetress of mercury;
2) be mixed: umber by volume, get 100 parts of above-mentioned rhizoma extracting liquids before the use, add 100～200 parts of iodophor solutions containing available iodine 0.3%～0.5%, and add calcium hypochlorite 0.8 gram～2.0 grams that contain available chlorine 25%～30% by per 100 milliliters of rhizoma extracting liquids.
The present invention has following advantage:
1. bactericidal effect is good.Because the present invention adopts biotechnology, make full use of the antibacterial and bactericidal action of the natural plants coptis, and cooperate small amounts of inorganic chlorhexidine-containing disinfectant calcium hypochlorite and contain the iodine disinfectant Iodophor and make, make the present invention have antibacterial and bactericidal effect simultaneously and act on strong characteristics well, its sterilizing rate reaches 98～99.99%, is 1.0 * 10 as coliform count
8Sewage about CFU/L adds after this compound disinfectant handles, and coliform count obviously drops to 1.0 * 10
4CFU/L compares with single component bactericide in the prior art, and bactericidal effect is more stable, more reliable, and activity is low, and bactericidal effect is strong, and multiple Gram-positive and negative bacteria are had inhibition and killing action.
2. non-secondary pollution.The present invention adopts biotechnology; based on natural plant extracts; its residuals does not cause secondary pollution; especially to the processing of coastal cities sanitary sewage; except effectively suppressing and kill pernicious bacterias such as Escherichia coli; this compound formulation does not influence the marine organisms of offshore sea waters, thereby has good environmental protection and ecological significance.In addition human body there is not toxic and side effect, non-corrosiveness, nonirritant, good stability.
3. biotechnology is adopted in the preparation of this compound disinfectant, mild condition, and extraction process is simple, leaching process does not add other chemical substance, and a water extracts, and what concentrate employing is the low-temperature reduced-pressure method for concentration, the preparation method is easy, uses simply, three kinds of compositions is mixed promptly gets bactericide before use.
4. applied widely.Compound disinfectant of the present invention is except the sterilization that is applied to liquid such as environmental wastewater, also applicable to otherwise sterilization and sterilizations such as families.
Below in conjunction with embodiment in detail the present invention is described in detail.
