Problems solved by technology

Southwest China is rainy, humid, and the temperature is low in winter. The effect of applying relevant technologies to deal with pig manure is poor, the cost is high, and it is difficult to apply effectively. It is urgent to develop an effective treatment of pig manure produced by intensive pig farms and produce organic fertilizer new method

Embodiment 1

[0025] Collect fresh horse manure, mix it with pig manure with a water content of 70-75% in a mass ratio of 1:10, and stack it in an incubator for 10 days to obtain the original bacterial agent; mix the original bacterial agent with a mass ratio of 1:10 Pig manure with a water content of 70-75% is mixed and stacked in an incubator for 10 days to obtain a fermented bacterial agent for production; to build a solar isolation greenhouse, the main material is a hollow solar panel with a light transmittance greater than 80%, and the top is curved structure with an area of ​​400m 2 , that is, the annual output of organic fertilizer is 1,000 tons; the mass ratio of 75% of ordinary calcium sulfate and 25% of ordinary calcium carbonate is mixed to make a nitrogen-preserving deodorant. Deodorants are added to pig manure with a water content of 70-75% according to the mass ratio of 1%, mixed evenly, composted with a thickness of 2 meters, a length of 10 meters, and a width of 5 meters, co...

Embodiment 2

[0027] Collect fresh horse manure, mix it with pig manure with a water content of 70% to 75% in a mass ratio of 1:10, and compost it in a fermentation tank for 10 days to obtain the original bacterial agent; mix the original bacterial agent with a mass ratio of 1:10 Pig manure with a water volume of 70-75% is mixed and stacked in the fermentation tank for 10 days to obtain a fermented bacterial agent for production; to build a solar isolation greenhouse, the main material is a hollow solar panel with a light transmittance greater than 80%, and the top is an arc-shaped structure. Its area is 800m 2 , that is, the annual output of organic fertilizer is 5,000 tons; the mass ratio of 75% of ordinary calcium sulfate and 25% of ordinary calcium carbonate is mixed to make a nitrogen-preserving deodorant. Deodorants are added to pig manure with a water content of 70-75% according to the mass ratio of 1%, mixed evenly, composted with a thickness of 3 meters, a length of 20 meters, and ...

Abstract

Disclosed is a method for treating pig manures to produce an organic fertilizer, which inoculates horse manures in pig manures and purifies and amplifies high temperature fiber bacteria thereof to prepare a zymogen agent through two times of high temperature fermentation, then composts are inoculated in a solar energy isolation greenhouse to produce the organic fertilizer. The method has advantages of fast compost starting, low cost of nitrogen protecting and deodorization agent, broad sources and good effects; and the whole process for producing the organic fertilizer is conducted in the solar energy isolation greenhouse, thereby effectively preventing secondary pollutions such as pig manures and diffusion of nutrients and realizing the clean treatment to the pig manures and production to the organic fertilizer. The method is suitable for the southwest area and the like in China abound with rain and moisture and with rather low temperature in winter, and has advantages of low investment, low energy consumption, low cost, simple operation, strong practicability and easy promotion.

Description

technical field [0001] The invention relates to the fields of modern animal husbandry, environmental pollution control and fertilizer. In particular, it relates to a method for cleanly producing organic fertilizer by treating pig manure produced by intensive pig farming in a harmless and low-energy manner mainly for the characteristics of rainy, humid, and low winter temperatures in southwest my country and similar areas. Background technique [0002] With the improvement of people's living standards, the continuous increase of the population, the increasing demand for meat products, and the advancement of science and technology, the traditional pig raising industry has developed rapidly into an intensive pig raising method, which has also brought a series of environmental issues. Around many pig farms, concentrated discharge of manure seriously pollutes the nearby land, water and air ecological environment, and effective treatment is urgently needed. [0003] At present, ...
