Description
Technical field
The present invention relates to a kind of method of utilizing the natural pond slag to produce mixed organic manure, belong to agricultural wastes comprehensive utilization field.
Background technology
In recent years, along with cities and towns and urban residents' standard of living improve constantly, impel the resident to the sustainable growth of meat, eggs and milk demand.Promoted livestock and poultry breeding industry to develop rapidly, the breed scale constantly enlarges.The agricultural wastes such as fecal sewage that livestock and poultry cultivation produces to atmospheric environment around the plant and resident living environment structure serious threat, have a strong impact on the quality safety that town dweller's life and agricultural-food are produced, therefore must carry out harmless treatment the fecal sewage of livestock and poultry farm.At present, utilizing the biogas engineering anaerobic fermentation technology to handle feces of livestock and poultry is the effective measure that solve environmental pollution, promptly can change the environmental situation around the plant, and can fully utilize to Organic farming production feces of livestock and poultry again provides quick-acting organic fertilizer.
The biogas that feces of livestock and poultry produces through the biogas anaerobic fermentation technology is used for producing after desulfurization and life, has saved the disposable energy, has reduced the atmospheric pollution that burning straw and coal cause.Natural pond slag, natural pond liquid can be used as the quick-acting organic fertilizer direct returning to farmland.Natural pond slag, natural pond liquid have many advantages as organic fertilizer: nutrient is complete, and fertilizer efficiency is lasting, contains the material that stimulates plant growth in the fertilizer, increases output, improves crop quality, the structure of improving the soil.Stalk, human and animal excreta can be killed most of worm's ovum and germ through anaerobically fermenting, alleviate the generation of crop pest, can alleviate residual in food such as agricultural chemicals, chemical fertilizer effectively.Also promote simultaneously the development of aquaculture, formed that plant production, animal transform, the benign cycle of micro-reduction, realized the increment again of livestock and poultry cultivation production and energy utilization.
Country satisfies the demand of people to meat, eggs and milk in order to promote the livestock and poultry breeding industry development, and factory subsidizes to large-scale cultivation, has accelerated the tempo of large-scale cultivation factory.Country is for solving the problem of environmental pollution of large-scale cultivation factory simultaneously; many big-and-middle-sized biogas engineerings have been built; the biogas that produces is used for generating electricity or using for productive life after desulfurization; natural pond slag, natural pond liquid as fertilizer sources use for agriculture production or directly are discharged in the sewer; caused fertilizer loss, natural pond slag, natural pond liquid as fertilizer sources use the problem that also exists the transportation difficulty.At present, also there is not a kind of method of easily, reasonably effectively utilizing natural pond liquid and natural pond slag.
Summary of the invention
The problem that purpose of the present invention exists in utilizing at liquid natural pond, above natural pond slag provides a kind of method of utilizing the natural pond slag to produce mixed organic manure.
For reaching above-mentioned purpose, a kind of method of utilizing the natural pond slag to produce mixed organic manure of the present invention may further comprise the steps;
1) culture factory and build the anaerobically fermenting biogas engineering, swine manure wastewater is entered biogas engineering fermentation and biogas production, natural pond slag, natural pond liquid, biogas uses or generating for productive life after desulfurization, and natural pond slag, natural pond liquid use for producing fertilizer.
2) solid-liquid separation is separated natural pond slag, natural pond liquid with solid-liquid separating machine.
3), add natural pond slag stirring and evenly mixing with the crop material crushing screening.When stirring, add the nutrient adsorbent with the easy nutrient of loss in the fixing natural pond slag.
4) with the natural pond slag, its N of crop material mixture sample examination, P, the K content that mix in the step (3).
5) according to N, P, K content in natural pond slag, the crop material mixture in the step (3), add nitrogenous fertilizer, phosphate fertilizer, potash fertilizer, the content that reaches N, P, K respectively is 15 or other proportionings.
6) the uniform mixture that will be mixed enters the granulation of volution stirring granulating machine.
7) particle of making in the step (6) is entered the oven dry of oven drying at low temperature equipment, pack is sealed, and forms the commodity mixed organic manure.
Beneficial effect of the present invention is:
Adopt the mixed organic manure that the present invention produced, contain active very strong active substance, help the characteristic of improving the soil, increase the content of microorganism in the soil, improve the activity of soil; Contain various plants growth again and need quick-acting inorganic nutrients such as the nitrogen phosphorus potassium of usefulness and trace element.The effect of existing fertilizer has plant growth regulation again; Both contained the needed available nutrient of plant-growth, the characteristic of can improving the soil again, culture fertility, the purpose that reach volume increase, increases income.And can reach and solve plant's environmental pollution, the purpose of raising quality of agricultural product.
