Straw incineration is a common agricultural waste treatment method, and its harm cannot be ignored. The following are the main hazards of straw burning:
1. Polluted air quality
Data show that when the straw is burned, the three pollution indexes of sulfur dioxide, nitrogen dioxide and inhalable particulate matter in the atmosphere reach their peak value, of which the concentration of sulfur dioxide is 1 times higher than usual, and the concentration of nitrogen dioxide and inhalable particulate matter is 3 times higher than usual, which is equivalent to the fifth level of the average daily concentration. Straw burning will cause haze weather and produce a large number of toxic and harmful substances, which poses a threat to human and other biological health
2. Damage soil structure
When the straw is burned into the ground, the microorganisms in the surface will be burned, and the humus and organic matter will be mineralized. This not only disrupts the balance of biological systems in the soil, but also changes the physical properties of the soil, aggravates soil compaction, reduces the natural fertility and water retention of the soil, resulting in the growth of crops being affected, and thus affecting agricultural yield123.
3. Start a fire
When burning straw, it is easy to ignite the flammable materials around, especially in the vicinity of mountain forests, and the consequences are unimaginable. Once a fire starts, it is often difficult to control, causing huge economic losses.
4. Affect traffic safety
As there are a large number of farmland on both sides of the highway, the smoke formed by burning stalks causes reduced air visibility and reduced visible range, which is easy to cause traffic accidents. Increase the probability of traffic accidents, endanger personal safety.
5. Health risks
The smoke produced by burning straw contains a large number of harmful substances, such as nitrogen oxides, photochemical oxidants and suspended particles, etc. These pollutants stimulate the eyes, nose and throat and other parts containing mucous membranes, causing cough, chest distress and tears, and may lead to bronchitis in serious cases. It is particularly significant for middle-aged and elderly people, children and people with respiratory diseases, which may cause or aggravate respiratory diseases.
Straw pellet machine is a kind of equipment that can compress biomass materials such as crop straw into granular fuel. It compresses crushed straw and other raw materials into particles with a certain shape and density through high pressure, which can be used as clean energy instead of traditional coal and natural gas as fuel, helping to reduce greenhouse gas emissions and meeting the requirements of sustainable development. It can also be used as feed or for other purposes, and the use of straw granulator to convert straw into pellets can largely solve the environmental problems caused by straw burning.
The popularization and application of straw pellet machine is of great significance for improving ecological environment and promoting sustainable development. It can effectively solve the problem of environmental pollution caused by straw burning, and also provide a new way for farmers to increase their income. The application of straw pellet machine can not only improve the utilization rate of crop straw, but also reduce the dependence on non-renewable energy sources, which has important environmental protection and social significance
