A kind of method of oxidation removal poultry fecaluria foul smell
Technical field
The present invention relates to a kind of animal dung urine deodorizing method and application thereof.
Background technology
The development of the fast development, particularly large-scale cultivation of producing along with livestock and poultry breeding industry, the generation of a large amount of animal wastes causes the poultry industry development and the contradiction of environmental pollution to show especially day by day.The topmost pollutant of livestock and poultry breeding industry are fecaluria and foul smell that anaerobic fermentation produced thereof.The main component of foul smell is volatile fatty acid, indole, phenolic compound, ammonia, volatile amine, volatile sulfur compounds etc.
Large-scale odor removal investment and operating cost are all higher, and for the higher point source of concentration of emission, effect is obvious.But to the uncontrollable discharge source of livestock and poultry farm and so on, collection and confinement of gases pipeline complexity, cost of investment increases greatly, and treatment effect is also undesirable.Existing market also has the deodorizer of employing deodorant, mainly contains chemical deodorizing agent, plant deodorant, microbial deodorant.Chemical deodorizing agent and plant deodorant are except that cost is higher, and the chemical deodorizing agent may produce secondary pollution, and the microbial deodorant cost is low than the above two, mainly are that flora is less, the cause that fermentation costs reduces, but flora I haven't seen you for ages reduces deodorizing effect.In addition, microbial deodorant can not long storage time, is difficult to long-distance transportation, and application is restricted.
Large-scale odor removal investment and operating cost are all higher, and for the higher point source of concentration of emission, effect is obvious.But to the uncontrollable discharge source of livestock and poultry farm and so on, collection and confinement of gases pipeline complexity, cost of investment increases greatly, and treatment effect is also undesirable.Existing market also has the deodorizer deodorant, mainly contains chemical deodorizing agent, plant deodorant, microbial deodorant.Though microbial deodorant can be kept permanent deodorizing effect, deodorizing effect is slow, and the deodorization rate is not high.And microbial deodorant can not long storage time, is difficult to long-distance transportation, and application is restricted.Chemical deodorizing agent and plant deodorant are except that cost is higher, and present chemical deodorizing agent may produce secondary pollution, chemical deodorizing agent such as H 2O 2, KMnO 4Can effectively remove H 2Foul gas such as S, methanthiol needs the long period and produces that toxic byproduct is arranged yet utilize such chemical oxide to remove stench.Therefore must seek the chemical deodorizing agent that oxidability is stronger and do not produce toxic byproduct.
Ferrate (FeO 4 2-) having a strong oxidizing property, its oxidability even be higher than ozone all has very strong oxidisability in whole pH scope, do not produced toxic byproduct, and its reduction product Fe (III) is a kind of good flocculating agent.Discover that potassium ferrate can be oxidized to nitrogen oxide, methanol and nitrogen respectively fast with azanol, N-methyl hydroxylamine, N-aniline, adjacent methyl hydroxylamine.The clearance of phenol in 20min can reach 98%.Potassium ferrate has good deactivation to escherichia coli, f2 virus, Q phagus beta, can also effectively kill staphylococcus aureus, bacillus subtilis black variety gemma and Candida albicans.Ferrate has caused the extensive concern of research worker as a kind of green novel water-treatment medicament.
But ferrate decomposes in water soon, and the Oxidation time is short, and some more dysoxidizable oxidation operations are incomplete.For this reason, with ferrate and hydrogen peroxide associating, the reduction product Fe of ferrate (III) catalyzing hydrogen peroxide produces the stronger hydroxyl radical free radical of oxidability, further oxidation odorous substance.
Summary of the invention
The method that the purpose of this invention is to provide a kind of foul smell of oxidation removal poultry fecaluria, it can overcome the above-mentioned shortcoming of prior art, and deodorizing method is simple, and cost is lower, and deodorizing effect is remarkable and permanent, non-secondary pollution.Livestock and poultry farm can needn't increase employee and equipment by oneself.

The advantage of animal dung urine deodorizing method provided by the invention is:
1) utilizes the strong oxidizing property of ferrate, rapidly oxidation removal part foul smell.Utilize hydrogen peroxide to produce the stronger hydroxyl radical free radical of oxidability again under the catalytic action of ferrate reduzate, complete oxidation is removed various foul smell compositions.Make deodorizing effect both rapid, efficient again permanent.
2) utilize the strong oxidizing property of ferrate, destroy cell wall, the cell membrane of antibacterial, and the enzyme in the cellularity, kill the microorganism in the poultry fecaluria, fundamentally suppress the generation of foul smell.
3) without any need for the deodorization facility, no cost of investment.Though the price of solid ferrate is higher, consumption is few.If adopt the aqueous solution of ferrate, though deodorizing effect is rapid, on rubbish, uses 10 minutes and take effect, impermanent, lose oxidation deodorant effect along with the decomposition of ferrate, will spray several times at least even tens every day.Therefore totle drilling cost is lower.
4) do not produce secondary pollution, but also help the subsequent treatment utilization of fecaluria.The reduction product Fe of ferrate (III) is a kind of good flocculating agent, and is nontoxic.Ferrate self decomposition also can produce oxygen.Peroxide breakdown also can produce oxygen, and the fecaluria oxygen content is increased, and produces foul smell thereby reduce by the fecaluria anaerobic fermentation.The water that hydrogen peroxide decomposes produces does not have influence to environment.
5) adopt solid ferrate, avoid the unstability of ferrate water preparation, and with hydrogen peroxide co-oxidation odorous substance.Deodorizing effect is permanent, after the sprinkling, can keep not having stink 4 days.
