Description

Closed manure and organic waste aerobic fermentation tank

technical field

The utility model belongs to the interdisciplinary field of animal husbandry machinery and biological engineering, in particular to a closed continuous aerobic fermenter for feces and organic waste.

Background technique

With the rapid development of the economy and the improvement of people's quality of life, people's demand for animal products and food will continue to increase, and animal products and food occupy an increasingly important position in people's lives. Relevant studies have shown that in recent years, the aquaculture industry has experienced unprecedented development and expansion around the world, and these developments are mainly characterized by large-scale and intensive operations. At present, my country is one of the big countries in livestock and poultry breeding. In recent years, with the continuous expansion of large-scale livestock and poultry farms, the pollution caused by the random discharge of livestock and poultry manure has become a key source of environmental pollution.

According to data, in 2003, the discharge of livestock and poultry manure in my country was about 3.2 billion tons, which far exceeded the total discharge of 1 billion tons of industrial waste in the whole year. By 2011, the waste of livestock and poultry manure in my country The total discharge of animals will exceed 4.6 billion tons, and the pollution from aquaculture has become one of the major sources of pollution in my country.

Excessive excrement of poultry and livestock is directly discharged into the environment without treatment, which will not only cause harm to human health and the ecological environment, but also affect the sustainable development of animal husbandry. Therefore, the prevention and control of poultry and livestock manure pollution Governance has become a matter of urgency. The hazards of poultry manure to the environment are manifested as: (1) water pollution; (2) air pollution. During the stacking and storage process, due to the high water content in livestock and poultry manure, a lot of malodorous gases (including ammonia, sulfide and methane, etc.) will be produced, polluting the air and affecting the ambient air quality. Among all poultry manures, dairy cows have the largest odorous gas. Many countries have strict standards and regulations on the emission of odorous gases. There are relevant regulations in Japan's "Odor Law". Accounted for as many as 6 kinds, namely trimethylamine, methyl mercaptan, dimethyl sulfide, hydrogen sulfide, ammonia and methyl disulfide, and later added 4 kinds of lower fatty acids (including propionic acid, n-butyric acid, n- valeric and isovaleric acids). These substances poison the respiratory center of human beings, stimulate the nervous system, and finally cause human diseases, affect the growth and development of poultry and livestock, and at the same time reduce the reproductive capacity of poultry and livestock. (3) Heavy metal pollution. When adding trace metal element additives (such as iron, copper, zinc and arsenic, etc.) to livestock and poultry feed, only a small amount of these trace elements can be directly digested and absorbed, and most of them are directly excreted with feces. Some people estimate that if a broiler farm with a breeding capacity of about 100,000 chickens uses organic arsenic growth agents for more than 15 years, the arsenic content in the soil in the surrounding areas will double. (4) Contamination by pathogenic microorganisms. Many pathogenic microorganisms, parasites and eggs exist in untreated poultry manure, and the breeding mosquitoes and flies cause the spread of parasites and infectious diseases; (5) Random discharge of poultry manure not only pollutes the environment, but also kills and eliminates The rate of increase year after year also threatens the sustainable and healthy development of animal husbandry itself. (6) Affect social stability. Untreated poultry manure is directly discharged into the environment, seriously polluting the surrounding waters and farmland, and constantly conflicting with the surrounding residents and farmers.

The traditional old method of manure fermenting as fertilizer is to let it accumulate and ferment naturally for 5-6 months, so that the smell will be emitted, which will not only pollute the environment but also cause a large loss of nutrients.

The applicant adopts the heaping method and uses the effective microbial agent to ferment the pig manure for the first time. The effective microbial agent can increase the temperature of the pile, make the high temperature period come earlier, accelerate the decomposition of organic matter, thereby accelerating the composting process and shortening the fermentation time; and then When carrying out the second fermentation, add functional composite microbial agent (nitrogen-fixing bacteria, phosphorus-dissolving bacteria, potassium-dissolving bacteria), and the beneficial bacteria (nitrogen-fixing bacteria, phosphorus-dissolving bacteria, potassium-dissolving bacteria) in the heap will get different degrees of Value-added, the available nitrogen, available phosphorus, and available potassium in the heap are released, so that the pig manure retains more nutrients and obtains higher fertilizer efficiency. However, there are problems such as polluting the environment and uneven fermentation.
