Problems solved by technology

Pig manure pollutes the groundwater, the microbial content exceeds the standard, and the toxic and harmful substances seriously exceed the environmental tolerance; at the same time, the air pollution from the manure is also obvious, and harmful gases such as ammonia and sulfur dioxide increase; moreover, the pig manure causes soil acidification, heavy metals, etc. Residue and other issues

Embodiment 1

[0021] A pig manure treatment method, comprising the following steps:

[0022] (1) Deodorization treatment: stack the pig manure to be treated on the bamboo poles, press the pig manure tightly, and then put a layer of bamboo poles on the pig manure, stack them in sequence, and form bamboo poles, pig manure, and bamboo poles from bottom to top. The stacking relationship is until the pig manure to be processed is piled up. The bamboo poles are cut into strips of 5-8m, and the thickness of the pig manure stacked in each layer is 50-60cm. When stacking bamboo poles, the ground clearance should be ≥ 30cm. After placing them for 2 to 3 days, mix the pig manure and fermentation bacteria 1 at a mass ratio of 1:0.2, mix well, and place the bamboo poles at a temperature of 28°C and a relative humidity of 35%. Fermentation is carried out in a fermentation room with a concentration ≥ 18%. After 6 to 8 days, the product after the first fermentation is mixed with the fermentation bacteria 2...

Embodiment 2

[0028] A pig manure treatment method, comprising the following steps:

[0029] (1) Deodorization treatment: stack the pig manure to be treated on the bamboo poles, press the pig manure tightly, and then put a layer of bamboo poles on the pig manure, stack them in sequence, and form bamboo poles, pig manure, and bamboo poles from bottom to top. The stacking relationship is until the pig manure to be processed is piled up. The bamboo poles are cut into strips of 5-8m, and the thickness of the pig manure stacked in each layer is 50-60cm. When stacking bamboo poles, the ground clearance should be ≥ 30 cm. After placing them for 2 to 3 days, mix the pig manure with the fermentation bacteria 1 at a mass ratio of 1:0.3, mix well, and place the bamboo poles at a temperature of 33°C and a relative humidity of 45%. Fermentation is carried out in a fermentation room with a concentration ≥ 18%. After 6 to 8 days, the product after the first fermentation is mixed with the fermentation bact...

Embodiment 3

[0035] A pig manure treatment method, comprising the following steps:

[0036] (1) Deodorization treatment: stack the pig manure to be treated on the bamboo poles, press the pig manure tightly, and then put a layer of bamboo poles on the pig manure, stack them in sequence, and form bamboo poles, pig manure, and bamboo poles from bottom to top. The stacking relationship is until the pig manure to be processed is piled up. The bamboo poles are cut into strips of 5-8m, and the thickness of the pig manure stacked in each layer is 50-60cm. When the bamboo poles are stacked, the ground clearance should be ≥30cm. After placing them for 2-3 days, mix the pig manure and the fermentation bacteria 1 at a mass ratio of 1:0.25, mix well, and place them in a room containing oxygen at a temperature of 30°C and a relative humidity of 40%. Fermentation is carried out in a fermentation room with a concentration ≥ 18%. After 6 to 8 days, the product after the first fermentation is mixed with the f...

Abstract

The invention belongs to the technical field of manure treatment, and particularly relates to a pig manure processing method. The method includes the following steps of deodorization treatment, heavy metal removal and preparation of gasket materials. By adopting the pig manure processing method, the content of sulfur compounds, nitrogen compounds and other malodorous gases in pig manure is effectively reduced, and the root cause of pig manure stink is fundamentally solved; in addition, the method has obvious effects on heavy metal transformation of pig manure, and the treated pig manure and other padding materials are made into gasket materials to eliminate the stench of pig manure and inhibit the growth and reproduction of pests and pathogens; and meanwhile, after fermentation, a large number of beneficial microorganisms are produced and can be used for synthesizing nutrients, such as carbohydrates, proteins, organic acids, vitamins, eaten by livestock, thereby enhancing livestock disease resistance, promoting the healthy growth of livestock, realizing changing waste into treasure and reducing the pollution of pig manure to the environment.

Description

technical field [0001] The invention belongs to the technical field of manure treatment, in particular to a method for treating pig manure. Background technique [0002] With the continuous development of my country's animal husbandry, the pig industry has made great progress, and my country has become the world's largest pig-raising country. According to the report of the National Bureau of Statistics, at present, the total amount of live pigs raised in my country (the amount of slaughter and the amount of stock) has exceeded 1 billion. The continuous development of the pig industry is gradually meeting the people's growing demand for pork, but it is also facing some increasingly prominent problems while developing. In recent years, large-scale pig farms have gradually increased, and there are fewer and fewer free-range farmers. The pig raising mode has changed from rural free-range farming to intensive pig raising. Pig food has also changed from leftover hogwash to unifie...
