Abstract
The invention relates to waste treatment, in particular to a pig-raising manure nitrogen-preserving deodorant and a production method thereof. Sulfuric acid, hydrochloric acid, magnesium sulfate and ferrous sulfate are taken as the main raw materials for preparing the nitrogen-preserving deodorant; the process is simple, and the cost is low, thereby solving the problem of environmental pollution caused by the pig-raising manure. The ingredients of the nitrogen-preserving deodorant by concentration ratio are as follows: 2-3ml/L of concentrated sulfuric acid, 2-3ml/L of concentrated hydrochloric acid, 20-30g/L of magnesium sulfate, 100-150g/L of ferrous sulfate and water. The production method is as follows: mixed solution of dilute sulfuric acid and dilute hydrochloric acid is prepared according to the mixture ratio, magnesium sulfate heptahydrate is added into the mixed solution for stirring and dissolution, then ferrous sulfate heptahydrate is added for stirring and dissolution, water is added for setting the volume, the solution is shaken up, and a finished product is obtained by being arranged in a container. The invention has reasonable formula, good nitrogen-preserving deodorizing effect and easy implementation, thereby being applicable to the pig manure treatment of small and medium-sized pig farms or family cultivation.
Description
Technical field
The present invention relates to offal treatment, be specially a kind of feces nitrogen-protecting deodorant and preparation method thereof of raising pigs.
Background technology
In recent years, along with the fast development of animal husbandry, animal husbandry is cultured scale and is increased progressively day by day, and the animal waste pollution problem becomes increasingly conspicuous.According to statistics, the whole nation feeding live pig amount in 2005 increased by 3.2 times than 2000, reached more than 84,000 ten thousand.Along with the improvement of people's diet structure, China's animal husbandry also has a bigger development, and feces of livestock and poultry also will increase year by year.Statistics shows, national feces of livestock and poultry year generation be about 17.3 hundred million tons, be 2.7 times of trade waste, wherein pig industry year defecation amount is 10.62 hundred million tons; Poultry husbandry year defecation amount is 1.7 hundred million tons.Nitrogen year, generation was about 1,597 ten thousand tons, phosphorus year generation be about 3,630,000 tons, the COD generation is about 6400 tons, considerably beyond the industrial discharge amount.According to measuring and calculating, a year number of animals raised be that the ammonia that 1000 pig farm drains in the environment is 100 tons, 30 tons in phosphorus.The emission intensity amount is about 1,000 ten thousand tons in the annual pig manure in the whole nation, and phosphorus is about 2,000,000 tons, and these pollutant will severe contamination surrounding and water source as not carrying out harmless treatment.
China's pig industry mainly is divided into intensive culture and the casual household cultures dual mode.Little raiser is mainly to be that basic point carries out pig-breeding behind the house before the room, and is most below 100.For a long time, a greatest problem that perplexs small-sized raiser is the handling problem of feces of raising pigs, because pig manure urine can not in time be handled, causes the deterioration of living environment.If, promoted mosquitos and flies and noxious bacteria to grow in a large number without handling directly discharging, the generation of pathogenicity Resistant strain, the consequence that antibiotic remains etc. are serious is so feces must could discharge through deodorization and purified treatment.Under the Chinese society doctrine new countryside construction and the overall background of building a harmonious society, the rural ecological environment of built environment grace especially comes into one's own, and the deodorization technology of live pig feces is subjected to extensive concern.
At present, the feces of raising pigs is handled a lot of mature technique and method is arranged.The one, as the energy, utilizing Unareobic fermentation is swine excrement and straw etc. is fermented together and to produce biogas, is that swine excrement utilizes effective method; Another kind is as fertilizer, the high temperature that utilizes quick decomposer degraded and in its sweat, produce, kill harmful pathogen and roundworm egg, unsettled material is changed into more stable humus, cooperate suitable inorganic nutrients to be mixed with bio-organic fertilizer again and dash and apply fertilizer.This kind method is economical and practical, non-secondary pollution, the major measure that has become the swine excrement recycling and preserved the ecological environment in recent years.
Raise pigs the discharging feces in contain harmful gass such as ammonia, hydrogen sulfide, amine, untimely cleaning or processing, further transform foul gass such as producing methyl mercaptan, dimethyl disulfide, methyl sulfide, dimethylamine and multiple lower fatty acid, stink can be multiplied, not as good as influencing the resident living environment, also can cause harmful effect to the healthy growth of pig.
At present, China has developed and has developed some deodorizer that utilize the swine excrement that chemistry and biological method be made into, but for some small-sized raisers, also there are more difficulty in most of technology and method aspect applying.Design the economical and practical feces nitrogen-protecting deodorant of raising pigs, for improve small-sized raise pigs to raise on a household basis grow environment and the local-style dwelling houses environment will have crucial meaning.
Summary of the invention
The object of the present invention is to provide a kind of feces nitrogen-protecting deodorant and preparation method thereof of raising pigs, utilize sulphuric acid, hydrochloric acid, magnesium sulfate and ferrous sulfate to be primary raw material, make nitrogen-protecting deodorant, its technology is simple, with low cost, solves the problem of the excrement and urine polluting environment of raising pigs.
For achieving the above object, the technical solution used in the present invention is as follows:
The nitrogen-protecting deodorant composition is by concentration ratio among the present invention: concentrated sulphuric acid 2-3ml/L, and concentrated hydrochloric acid 2-3ml/L, magnesium sulfate 20-30g/L, ferrous sulfate 100-150g/L, surplus is a water.
Concrete manufacture method is as follows:
(1) get an amount of industrial concentrated sulphuric acid by proportioning, slowly join in the container that fills tap water (accounting for total amount 70-80%), the limit adds sour limit stirs cooling;
(2) slowly add concentrated hydrochloric acid by proportioning in liquid coolant, the limit adds sour limit stirs cooling; Make the mixed liquor of dilute sulfuric acid and dilute hydrochloric acid;
(3) in mixed liquor, add Magnesium sulfate heptahydrate, be stirred to the magnesium sulfate dissolving by proportioning;
(4) add ferrous sulfate heptahydrate by proportioning at last, stir, the ferrous sulfate of adding is fully dissolved; Cooling adds suitable quantity of water, reaches the prescription requirement, shakes up, and the container of packing into gets finished product.
