The meat protein and animal fats in food waste mainly come from those livestock and poultry that provide meat food, and livestock are prone to "cannibalism" homologous pollution after directly eating food waste that has not been effectively treated, and cause cross-transmission of epidemics between humans and animals, endangering human health, and may promote the spread of certain deadly diseases. The seepage generated when food waste is stacked enters the sewage treatment system, which will cause an increase in the content of organic matter, thereby increasing the burden on the sewage treatment plant and increasing the operating cost.
Equipped with microbial flora capable of decomposing household organic waste. These carefully cultivated and screened microbial flora specialize in "eating" organic waste such as vegetable leaves, bones, vegetables, melons and fruits. Only the organic waste needs to be put into the equipment, and at the same time it is inserted with microbial agents, and through high-speed fermentation, drying, odor removal and other processes, the organic waste can be effectively degraded on the spot, and the reduction, resource and harmlessness of garbage disposal can be achieved from the source. In addition, the decomposition products are water vapor, carbon dioxide, etc., which consume less electricity and truly achieve low carbon.
Since last year in Shanghai, the enforcement of garbage sorting has kicked off nationwide. The problem of garbage disposal after classification is also a major problem at present. Traditional treatment methods include incineration, landfill, microbial treatment, etc., and microbial treatment is divided into anaerobic and aerobic microbial methods, and various treatment methods have their own advantages and disadvantages, here is a further analysis of aerobic microbial treatment.
Aerobic microbial treatment usually has high temperature, medium temperature, medium and low temperature microbial strains. There are large differences according to the temperature required for the activity of microbial strains. High-temperature strains, generally above 100 °C, in order to maintain such a high temperature, energy consumption is particularly large, and it is rarely used at present. Medium temperature strains, generally at 45-70 °C, most of the current compost uses this method, there will be 5%~10% biomass residue after output, and the comprehensive energy consumption can meet the national energy conservation and emission reduction standards. Low-temperature strains, generally at 30-50 degrees Celsius, have low energy consumption, have a very good energy consumption ratio, and generally completely eliminate the organic components in food waste, and the reduction rate can reach 99%.
Extinction type kitchen waste treatment equipment is very suitable for local treatment, due to the use of low-temperature strains, low energy consumption, and the reduction rate is as high as 99%, no discharge is required all year round, low labor maintenance costs, and has great advantages in local source treatment. Since there is no need to discharge materials, there is no need to consider the residue after compost fermentation.
In addition, the elimination of food waste treatment equipment also has the advantages of high integration, small footprint, intelligent control, high degree of automation, etc., does not require manual attendance, and is very suitable for use in communities, schools, warships, unit canteens, scenic spots and other places.
