Description
Technical field
The invention belongs to deodorizer technical field, relate in particular to a kind of deodorizer that is applicable to the stench that disposal of refuse brings.
Background technology
Sanitary Landfill is the place of solid waste being carried out to stabilisation, harmless treatment disposal, but due in landfill process and processing disposal process, house refuse inside exists complicated physics, chemistry and microbial process, thereby can produce a large amount of foul smellings, have strong and stimulating abnormal smells from the patient, inflammable, explosive complicated gas component, this can exert an adverse impact to the atmospheric environment in city.Along with improving constantly of the enhancing of people's environmental consciousness and the requirement to environmental quality, the pollution that people bring the stench causing because of house refuse is also more responsive.
For the stench problem of refuse landfill, main processing method is physical absorption, plant extract processing and control of microorganisms etc. at present.For example, application number is that the Chinese patent application of CN201210184344.3 discloses a kind of deodorization absorbent that is applicable to refuse landfill, it can play certain deodorization, but physical absorption deodorization existence effect slowly and can only remove the shortcoming of the odorant of limited quantity, and the absorption of this adsorbent needs to be further processed after saturated and even need to carry out desorption processing, can cause so again secondary pollution; For another example, application number is the preparation method that the Chinese patent application of CN201010617598.0 discloses a kind of deodorizer, this deodorizer is plant extract deodorant, the deodorizer that adopts the disclosed method of this application to prepare has deodorizing effect relatively preferably, but its clearance to ammonia only has 63% left and right, and adopt plant extraction liquid deodorization also to have the problems such as reaction is slow, effective ingredient content complicated and effective ingredient is relatively low; For another example, application number is that the Chinese patent application of CN201110272839.7 also discloses a kind of microbial deodorant and bacterial strain thereof that is applicable to refuse landfill and garbage transfer station, it also has good deodorizing effect, but because colony growth is to environmental condition (as temperature, humidity and acid-base value etc.) sensitivity, easily cause the unsettled problem of deodorizing effect so there is the variation of environment.
Summary of the invention
The object of the invention is to: for the deficiencies in the prior art, and provide a kind of deodorizer that is applicable to the stench that disposal of refuse brings, it has, and deodorization is rapid, deodorizing effect significantly, the advantage such as stable and persistent period is long.
To achieve these goals, the present invention adopts following technical scheme:
A kind of deodorizer, comprises deodorant liquid A and deodorant liquid B, and wherein, by mass percentage, described deodorant liquid A comprises:
Antibacterial 1%～10%;
Stabilizing agent 2%～8%;
Water 82%～97%;
Described deodorant liquid B comprises:
Gel 4%～12%;
Acid-base modifier 1%～10%;
Water 78%～95%.
Wherein, in deodorant liquid A, antibacterial is for killing the various microorganisms that rubbish exists, or reduces the activity of microorganism, thereby reduces the release of foul gas, and meanwhile, the antibacterial odorant of can also effectively degrading, reaches the effect of stable and lasting deodorization.Stabilizing agent, for improving the stability of antibacterial at water, because some antibacterial are water insoluble, therefore, need to use stabilizing agent to improve uniformity and the stability of the dispersion of antibacterial in water.
In deodorant liquid B, gel is for forming the good rete of one deck barrier properties for gases on rubbish surface, and to stop the release of the gas with foul odour, acid-base modifier is in order to regulate the pH value of gel in water, preventing that gel from flocculating, sedimentation etc.
One as deodorizer of the present invention is improved, and by mass percentage, described deodorant liquid A comprises:
Antibacterial 3%～7%;
Stabilizing agent 3%～6%;
Water 87%～94%;
Described deodorant liquid B comprises:
Gel 6%～9%;
Acid-base modifier 3%～8%;
Water 83%～91%.
One as deodorizer of the present invention is improved, and described antibacterial is selected from least one in inorganic chlorine antibacterial, organochlorine antibacterial and organosulfureous fungicide, and these several antibacterial all have and kill preferably or inactivating efficacy microorganism.
One as deodorizer of the present invention is improved, and described inorganic chlorine antibacterial is selected from least one in liquid chlorine and chlorine dioxide; Described organochlorine antibacterial is selected from least one in dichlorophen, dodecylbenzyl ammonium chloride, bromine chlorine hydantoin, cypermethrin, sodium dichloro cyanurate and sym-closene; Described organosulfureous fungicide is selected from least one in ethylene bisdithiocarbamic ammonium and PZ.
Improve as the one of deodorizer of the present invention, described stabilizing agent be selected from vulcabond, maleic anhydride, boric acid, Borax, glutaraldehyde and and persulfate at least one.
One as deodorizer of the present invention is improved, and described gel is selected from least one in sodium carboxymethyl cellulose, alginate jelly, polyethylene, polyvinyl alcohol, polyacrylamide and aluminosilicate.
One as deodorizer of the present invention is improved, and described acid-base modifier is selected from least one in dilute hydrochloric acid, dilute sulfuric acid, citric acid, phosphate and sodium hydroxide.Phosphate can be selected dibastic sodium phosphate and/or sodium hydrogen phosphate.
One as deodorizer of the present invention is improved, and the using method of described deodorizer comprises the following steps:
The first step, is first sprayed at deodorant liquid A on the rubbish for the treatment of deodorization processing equably by the first atomising device;
Second step, then by the second atomising device, deodorant liquid B is sprayed on the rubbish through first step processing equably, deodorant liquid A and deodorant liquid B are mixed on the surface of rubbish.
When actual use, can dilute deodorant liquid A and deodorant liquid B as required.
One as deodorizer of the present invention is improved, and described the first atomising device and described the second atomising device are all set to mobile atomising device or fixing atomising device.
One as deodorizer of the present invention is improved, and described the first atomising device and described the second atomising device are all set to high pressure sprays fog equipment, and the interval of first step spraying operation and second step spraying operation is 1min～10min.
With respect to prior art, the present invention is by preparation independent deodorant liquid A and deodorant liquid B, when use, first deodorant liquid A is sprayed on rubbish, and then deodorant liquid B is sprayed on rubbish, deodorant liquid A and deodorant liquid B are mixed on rubbish surface, thus the foul odour in rapid (3min～5min) Jian Dan garbage loading embeading district.After 40min～60min, gel in deodorant liquid B can form nontoxic on the surface in garbage loading embeading district, the rete that barrier properties for gases is good, this rete can reduce the release of foul gas, and in this rete, include the component in deodorant liquid A, biocide molecules in the deodorant liquid A of rete place is slowly discharged, thereby rapidly and continue to kill harmful microorganism and decompose odorant as hydrogen sulfide, ammonia and trimethylamine etc., and the formation of this rete can also long term inhibition garbage loading embeading district the activity of microorganism, and then slow down the discharge of foul gas, reach the effect of stable and lasting deodorization.Experiment shows: the surface that the present invention is sprayed to garbage loading embeading district is after 3 minutes ~ 8 minutes, and the foul odour in garbage loading embeading district significantly reduces, and meanwhile, also can realize following effect: Staphylococcus albus killing rate is reached more than 99.93%; Escherichia coli killing rate is reached to 100%; The clearance of ammonia is reached more than 89.8%; Clearance to hydrogen sulfide reaches more than 98%, and deodorizing effect can continue 4 days ~ 7 days.In the present invention, rete and antibacterial have deodorization effect.
