Before garbage incineration, the garbage is always sorted, because the types of garbage are different, the hazards are also different, and the type of municipal solid waste incinerator is also needed. Let's see what we need to do before the waste is incinerated.
On the one hand, due to the classification and collection of their domestic waste, the non-combustible components such as muck glass, metal, bricks, and porcelain tiles in the domestic garbage sent to the combustion plant are relatively small, and on the other hand, the moisture of domestic waste is lower due to the less kitchen waste in these countries. In general, the calorific value of domestic waste in these thriving countries is high.
In addition to the similar temperature conditions, the matrix components of the reactions are very different, and the carrying conditions are also different, so it is difficult to describe the fermentation reactions in the domestic waste fermentation ponds. Generally speaking, the matrix of fermentation reaction in the domestic garbage fermentation pond is biological organic matter, which mainly includes starch, sugar, protein, lipid, etc., which are catalyzed by different enzymes under suitable conditions and synthesized into small molecule organic matter by a variety of different microorganisms, and at the same time release heat to the outside world. The synthesis produces a local small molecule substance that is excreted in a gaseous state (such as methane, carbon dioxide, etc.).
Anaerobic fermentation can be divided into three processes, firstly, the solid organic matter is hydrolyzed by the in vitro enzymatic hydrolysis of microbial exozyme, and the complex organic matter is hydrolyzed and fermented into simple soluble organic matter, such as polysaccharides are hydrolyzed into monosaccharides, proteins are converted into amino acids, and fats are converted into glycerol and fatty acids. The second step is to convert the products of the stage into low-grade volatile fatty acids, such as acetic acid, propionic acid and butyric acid, under the action of acid-producing bacteria. The third step is the fermentation of simple organic matter into methane and carbon dioxide, which are severely anaerobic, by methanogens. In engineering, the above three stages are generally simply divided into two parts: acid production and marsh production. There are a combination of the above repercussions that cease in the domestic waste dump fermentation pond, but the repercussions that cease are often incomplete.
In the process of burying household waste, the bacteria produced can seriously endanger our health. While it's hard to spot in a short period of time, there will always be people who will be affected by this over time. The present invention is inexpensive, simple to operate, and the effect is remarkable. Good bye.
