What are the benefits of biogas centric agroecology

Green, organic, pollution-free, energy-saving.

One is energy efficiency. Biogas is produced from livestock manure to obtain high-quality domestic and ecological energy, which is used for processing non-staple foods and heating, replacing liquefied gas and coal gas.

The second is the benefit of environmental sanitation. Purify the ecological park, create a hygienic production and living environment and a clean image of the park, and improve the interior appearance of the park.

The third is ecological efficiency. The ecological benefits of biogas are reflected in the ecosystem of the park, livestock and poultry manure is the main raw material for making biogas, biogas is a pollution-free fuel, can replace coal gas or liquefied gas; Biogas slurry is also a high-quality organic fertilizer, which can be used for planting vegetables, grains, seedlings, etc. At the same time, biogas slurry can be converted into aquaculture feed after biological treatment, which is a high-quality feed for fish, shrimp and special aquatic products.

Fourth, economic benefits. In addition to generating energy benefits, biogas can also bring direct economic benefits, as the core and link of the agricultural ecosystem, it drives the development of planting, processing and breeding in the ecological park, and expands the profitable project chain of the ecological park. In addition, the use of biogas slurry can replace chemical fertilizer, saving fertilizer costs, the current ecological park produces 30m3 of biogas per day, saving fuel costs of 10,000 yuan per year.

Fifth, social benefits. With rural biogas as the working link, we will spread a comprehensive and efficient production mode to rural areas, spread a clean, civilized and modern way of life, and lead rural farmers to achieve prosperity and close to civilization.

Biogas is a flammable gas generated by the fermentation of microorganisms under anaerobic conditions by organic matter (human and animal manure, domestic sewage, agricultural waste, etc.), its main components are methane (accounting for 55 70%) and carbon dioxide (accounting for 25 40%), it is a renewable biomass energy, with the characteristics of high quality, clean, cheap, easy to prepare, etc., because this gas was originally found in the swamp, so it is called biogas.

The comprehensive utilization technology of biogas ecological agriculture is to build a biogas digester, use human and animal manure, domestic sewage, agricultural waste, etc. into the pond for fermentation, produce biogas, biogas slurry and biogas residue for daily life and agricultural production, reduce production costs, improve economic benefits, so as to form a benign development chain of farmers' life, biogas fermentation, and ecological agriculture.

The biogas digester can ferment decomposable household waste and improve the utility of fertilizer. However, if you want to do a good job in ecological agriculture, you have to learn microbial cultivation, because the ecological cycle is inseparable from microorganisms, and microorganisms are the most easily ignored by most people who do ecological agriculture. Without microorganisms, it is no longer an ecology.

<> normal operation, biogas has no impact on the environment. Attention should be paid to the use of biogas: before using biogas, the gas source should be connected first, and each joint should be fastened; Light the ignition first, and then slowly twist the switch to prevent too much biogas from being released; Biogas lamps, stoves and gas pipes should not be placed near flammable materials; If you smell rotten eggs indoors, open doors and windows quickly to ventilate; It is forbidden to ignite and test the gas at the gas pipeline mouth and discharge port of the biogas digester; In the event of a fire, immediately turn off the gas supply.

1. Does biogas pollute the environment?

1. The main component of biogas is methane, and there are no mosquitoes and flies around the biogas digester under normal operation, and it can also improve the environment, so it generally has no impact on the environment.

2. What should be paid attention to when using biogas:

1) Before using biogas, the gas source should be connected, and each joint should be fastened, and soapy water can be used to check whether there is air leakage at each joint.

2) When using biogas, you should first ignite the ignition and then slowly twist the switch to prevent too much biogas from being released, burning the body or causing disasters.

3) Biogas lamps, stoves and gas pipes should not be close to flammable materials to prevent fire, and in the event of a fire, immediately close and cut off the gas source.

4) If you smell rotten eggs indoors, quickly open the doors and windows to ventilate, or use a blast to expel the biogas outside.

5) It is forbidden to ignite and test the gas at the air guide pipe mouth and discharge port of the biogas digester to prevent backfire and damage to the biogas digester.

2. The benefits of establishing biogas digesters in ecological agriculture

1. The establishment of a biogas digester can use livestock manure to produce biogas, and the biogas obtained from it can be used for processing non-staple food and heating, and can also replace liquefied gas and gas.

2. The establishment of a biogas digester can purify the environment and create a hygienic production environment and living environment.

3. Biogas slurry is a high-quality organic fertilizer, which can provide fertilizer for vegetables, grains and other crops, and after biological treatment, biogas slurry can be converted into breeding feed, which is a high-quality feed for fish and other special aquatic products.

4. The establishment of a biogas digester can also reduce production costs and improve economic benefits, which can be used in daily life and agricultural production.

1. It is conducive to the protection of the ecological environment. The development of biogas solves the fuel problem of farmers and improves the agricultural ecological environment.

2. It is conducive to solving the problem of rural energy. As long as the fermentation raw materials are sufficient, the reputation of the stalls is empty and well managed, the fuel problem of lighting and cooking rice can be solved.

3. It is conducive to improving sanitary conditions. Using biogas as fuel, it is smokeless, dust-free, and easy to clean. Some manure, garbage, domestic sewage, etc. are good raw materials for biogas fermentation, thereby improving the environmental sanitation conditions in rural areas and benefiting the health of people and animals.

4. It is conducive to promoting the development of agricultural production. A large amount of livestock and poultry manure is added to the biogas digester for fermentation, which can produce biogas, and can make a large number of high-quality organic fertilizers, expanding the quality of organic fertilizers.

5. It is conducive to promoting the development of animal husbandry. After the biogas is started, it is conducive to solving the contradiction of "three materials" (fuel, feed and fertilizer) and promoting the development of animal husbandry.

6. Production of pollution-free vegetables. The carbon dioxide produced by passing biogas into the greenhouse and burning it can be used as a gas fertilizer, which can not only promote the growth of plants, but also inhibit the occurrence of many pests and diseases.

7. It is conducive to the liberation of labor. It saves the time of cooking and cooking, and reduces the housework. Biogas is a clean energy source, so countries are promoting it in rural areas.

No matter which ecological agriculture construction mode, it is inseparable from biogas digesters and biogas projects.

Hello dear<>

The answer you're looking for: Yes, both biogas digesters and biogas plants play an important role in the construction of ecological grinding agriculture. Biogas is an energy source that can be produced by fermentation of organic wastes such as rural domestic waste, agricultural waste, and livestock and poultry manure.

In the construction mode of ecological agriculture and cluster industry, biogas can be used as a resource for agricultural production, which can be used for heating, lighting, cooking and other production and living purposes, which can replace traditional fossil energy and reduce environmental pollution. At the same time, the biogas digester can also be used as a model of ecological agriculture, by fermenting agricultural waste to produce biogas, and then applying biogas residue as organic fertilizer to farmland, to achieve the recycling of resources, reduce waste emissions, and achieve the purpose of environmental protection and sustainable development. Therefore, biogas digester and biogas project are an indispensable part of the ecological agriculture construction model, which plays an important role in the sustainable development of agricultural production and environmental protection.

1. The normal working air pressure in the pool cannot be greater than 12000 Pa? The pressure that the foundation should be able to withstand should not be less than 50,000 Pa.

2. Biogas production is mainly based on the use of human, animal (poultry) manure, straw, weeds, corn, sorghum stalks and other organic matter as raw materials, which are fermented in the biogas digester. According to the survey, a family of five needs to consume 1m3 of biogas every day to cook rice and stir-fry vegetables and take a hot bath, so how much dry firewood can be saved every day? (The calorific value of biogas is about:.)

The calorific value of dry firewood is about:

84000000 12000000 = 7 kg, saving 7 kg of dry firewood per day.

3. What are the benefits of promoting the use of biogas to the rural living environment or ecological environment?

It is an important part of improving the rural environment and building ecological agriculture. Scientific planning, rational development and comprehensive utilization of biogas resources are of great significance for protecting forest vegetation, enhancing soil fertility, curbing soil erosion, reducing conventional energy consumption, reducing agricultural environmental pollution, improving comprehensive agricultural production capacity, increasing farmers' income, improving farmers' living environment, improving farmers' quality of life, realizing a virtuous cycle of agricultural ecological environment, promoting the sustainable development of agriculture and rural economy, and comprehensively promoting the construction of a new socialist countryside.

Specifically; 1. Eliminate the pathogens produced by rural livestock and poultry manure; air pollution and other hazards. 2. Biogas fertilizer is provided for crops.
