Description

A kind of feces of livestock and poultry deodorant
Technical field
The present invention relates to a kind of feces of livestock and poultry deodorant, belong to the processing technology field of debirs.
Background technique
China's livestock and poultry breeding industry is quickly grown, currently, about 2,700,000,000 tons of feces of livestock and poultry that China rural area generates every year.Although poultry Poultry manure is also the precious resources in agricultural production, and nitrogen that domestic livestock and poultry farm year generates, phosphorus are respectively up to 15,970,000 tons and 363 Ten thousand tons, it is equivalent to the 78.9% and 57.4% of China's same period fertilizer amount, but being continuously increased with feces of livestock and poultry, it stacks on the spot Stink is big, and mosquitos and flies is more, pollutes air and water source；Directly make fertilizer infectivity disease and insect pest, it is difficult to digest, be needed rapidly on the spot Carry out harmless treatment.There are many method for innocent treatment, and wherein stacking ventilation aerobic fermentation is more common and easy to operate, fast Spend faster processing method.In order to reduce the stink generation of stacking early period, accelerate the decomposition rate of waste, it would be desirable to poultry Poultry manure carries out deodorizing process.Generated foul smell main component is NH in livestock excrement composting treatment process3And H2S.It is right at present Generated foul smell available physical, chemistry and biological method are handled in Composting Process.Physical deodorization method mainly has washing Method, absorption method, screening agent method and high-altitude diffusion method, chemical deodorization method mainly have direct combustion method, chemical oxidization method, neutralisation and High-temperature oxidation, biological odor removal method are to be decomposed using microorganism, convert stink odor to reach deodorization purpose, therefore also cried micro- Biological odor removal method.But compost deodorizing is carried out using the method for physics and chemistry, effect is preferable, but there is investment and operating cost High, the problems such as secondary pollution is serious.Deodorization is carried out to compost using biological method, the effect in laboratory may be fine, but by It is limited in microbial activity by environmental condition, it is difficult to ensure that the deodorizing effect of compost.
Patent 201510097566.5: " a kind of During High-Temperature Composting nitrogen-protecting deodorant and its application " propose use by calcium chloride, The deodorant of iron chloride, alkyl glycosides and water composition, is added in raw material, to debirs During High-Temperature Composting using the method for spray The processing of stink in the process.But the deodorant is liquid substance, is difficult to control the dosage of deodorant when in use, and spraying During it is difficult to ensure that deodorant covering uniformity.
Patent 201410006033.7: " livestock and poultry farm deodorant and application " propose using by 15~50g acetic acid, 50 The copper sulphate of~100g is settled to 500ml preparation with water and obtains, deodorant is packed into open-top receptacle and is suspended on by vent window. The deodorant is also liquid substance, in use, being not added directly into feces of livestock and poultry, cannot fundamentally solve asking for stink Topic.
Summary of the invention
The purpose of the present invention is to provide a kind of feces of livestock and poultry deodorant, the deodorant utilizes chemicals and biology system The synergistic effect of agent carries out stink processing to feces of livestock and poultry；Deodorant is micro-nano type particulate matter, is added using the method for sprinkling Into feces of livestock and poultry, not only stink can be solved the problems, such as with uniform fold but also fundamentally；The deodorant is by following Raw material is prepared by mass percentage: flyash 50%~70%, silicon powder 17%~25%, additive 10%~17%, Inoculant 3% ~9%, the additive is one or more substances of calper calcium peroxide, calcium oxide and Nanoscale Iron.
Preferably, flyash of the present invention, calper calcium peroxide, calcium oxide, Inoculant granularity be 1000~2500 mesh, receive The granularity of meter Tie is 70~100nm, and the granularity of silicon powder is 200~500 mesh；The difference of granular size is formd by suction-operated Composite particles, the surface that flyash, additive and Inoculant are adsorbed on silicon powder particle form composite particles, and each substance can be sent out Wave its respectively due effect.
Deodorant of the present invention the preparation method comprises the following steps: additive, Inoculant are sequentially added flyash according to mass ratio In, it is sufficiently mixed uniformly, is then added to silicon powder in uniformly mixed mixture, be uniformly mixed to obtain the final product.
Inoculant of the present invention is the material in secondary fermentation stage during livestock excrement composting.
Flyash of the present invention is the solid waste of coal-burning power plant's discharge, main component are as follows: SiO2、Al2O3、FeO、 Fe2O3、CaO、MgO 、K2O、 Na2O、MnO2Deng, most of is oxide soluble easily in water, react with water generate alkaline matter and Volatile fatty acid reacts forming salt, can greatly reduce the yield of this important malodorous compound of volatile fatty acid.
The present invention also provides application of the feces of livestock and poultry micro-nano deodorant in livestock excrement composting, specifically: compost is opened When the beginning, the ratio of stool quality 0.5~5% is accounted for according to deodorant, gradually or is disposably sprayed into deodorant using spray appliance In feces of livestock and poultry, it is uniformly mixed carry out compost, with the passage of compost time, thorough deodorization can be completed after a week.
The present invention provides shown in spray appliance (Fig. 1)；Deodorant is entered by drain hole 1, and air is passed through manual by air inlet 3 Deodorant composite particles are blown in pipeline 4 by 2 air blast of air blower, are sprayed away by the sprinkling mouth 5 below pipeline, air blower can To provide very big wind-force, makes deodorant composite particles by evenly spreading out after sprinkling mouth, achieve the effect that uniform fold.
Compared with the prior art, the advantages of the present invention are as follows:
(1) feces of livestock and poultry deodorant of the invention handles feces of livestock and poultry, and worm's ovum, pathogen contamination are reduced, be finally effectively reduced The yield of smelly metallic substance during livestock excrement composting, granularity is very small, is directly sprayed onto livestock excrement composting when using It just can reach the effect of all standing in raw material.
(2) flyash in feces of livestock and poultry micro-nano deodorant of the invention is very high in China's yield, and harm is big, therefore reachable To the effect of waste resource recovery.
(3) feces of livestock and poultry micro-nano deodorant of the invention is significant to deodorizing effect during livestock excrement composting.Through testing Measurement, stink can be eliminated in the latter week left and right of compost, and compared with the Traditional compost deodorization time, stink eliminates the time and does sth. in advance 15 days More than.
(4) preparation method is simple, low in cost, easy to use.
