Abstract
The invention relates to a poultry waste deodorization method and the application thereof. The invention is characterized in that: firstly, peroxidase solution of 0.5U/mL to 1.5U/mL and hydrogen peroxide solution of 1 to 4 percent is made up, and the peroxidase solution is sprayed on the poultry waste (spraying 3mL for each liter of waste), and then the hydrogen peroxide solution with the same volume is sprayed, or calcium superoxide powder of 75 percent (spraying 0.3 to 0.5 g for each liter) is sprayed. Using the principle that the peroxidase ensures that the aromaticity compound is catalyzed and oxidized to free radical to be decomposed and eliminated by using peroxide or calcium superoxide as an electron acceptor in the range of having wider temperature, PH value, pollutant concentration and salinity, the bad smelly produced by poultry waste in a poultry cultivation farm is eliminated. The deodorization method is simple without any complex facility, and any staff and device are not needed to be increased having no investment cost and having low running cost. The deodorization effect is obvious and can last for a long time, and secondary pollution can not be caused. The invention has application prospect in the meager profit industry of livestock breeding.
Description
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 pollutent of livestock and poultry breeding industry is the foul smell that fecaluria and anaerobically fermenting thereof produce.The main component of foul smell is voltaile fatty acid, indoles, phenolic compound, ammonia, volatile amine, volatile sulfur compounds etc.
Large-scale odor removal investment and running cost are all higher, and for the higher point source of emission concentration, 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 reodorant of employing de-odorised, 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.
Peroxidase can be an electron acceptor(EA) with hydrogen peroxide or calcium peroxide in temperature, pH value, Pollutant levels and the salinity range of broad, is that the phenol oxyradical decomposes removal with the phenolic compound catalyzed oxidation.Handle in the research and show containing phenol, amino benzene analog waste water, can remove phenol and aniline more than 30 kinds, the clearance of some phenol is reached 99%.
Summary of the invention
The purpose of this invention is to provide a kind of deodorizing method and application thereof of livestock and poultry fecaluria, it can overcome the above-mentioned shortcoming of prior art, and this deodorizing method is simple, and cost is lower, and deodorizing effect is remarkable, can not cause secondary pollution.Plant can needn't increase employee and equipment by oneself.
Animal dung urine deodorizing method of the present invention, it is characterized in that superoxide enzyme solution and 1%～4% superoxol of preparation 0.5U/mL～1.5U/mL earlier, on the livestock and poultry fecaluria, spray superoxide enzyme solution (every liter of fecaluria sprays 3mL) earlier, spray isopyknic superoxol again, or 75% calcium peroxide powder (every liter of fecaluria sprays 0.3g～0.5g) get final product.
The advantage of animal dung urine deodorizing method provided by the invention is:
1) without any need for the deodorizing facility, no cost of investment.Though the price of horseradish peroxidase is higher, consumption is few, also can select the lower soybean peel peroxidase of price or the isozyme of other peroxidase, so total cost is low.
2) do not produce secondary pollution, but also help the subsequent disposal utilization of fecaluria.The oxygen that peroxide breakdown produces can make oxygen content increase in the fecaluria, produces foul smell thereby reduce by the fecaluria anaerobically fermenting.The water that hydrogen peroxide decomposition produces does not have influence to environment.Calcium peroxide decomposes the physico-chemical property that the calcium ion that produces can improve soil, makes fecaluria land use preferably.
3) deodorizing effect is permanent, after the sprinkling, can keep not having stink 3 days.
4) the enzyme source of peroxidase is abundant, and storing is convenient.Livestock and poultry farm can spray and use voluntarily with using with joining, and is simple and convenient.
