Description
Technical Field
The invention belongs to the field of environmental protection, and particularly relates to an integrated comprehensive utilization system and method for treating and recycling food waste.
Background
The kitchen waste is a general name of the residual food discarded by institutions, schools, collective canteens, restaurants and hotels, and comprises discarded vegetable leaves, leftovers, fruit peels, fruit kernels, egg shells and the like, and can also comprise bones of various meats, tea leaves and the like in a wider sense. Compared with other wastes, the kitchen waste has the characteristics of high water content, organic matter content, grease and salt content, high possibility of putrefaction and the like. The kitchen waste is easy to ferment, deteriorate and rot, so that a large amount of toxin is generated, malodorous gas is emitted, water and atmosphere are polluted, the living environment is seriously influenced, harmful substances such as pathogenic microorganisms and mycotoxin are easy to grow, and the potential threat to the health of people exists. At present, the main treatment methods of the kitchen waste comprise:
1. physical sorting treatment: the separation of each component in the garbage is realized by adopting a series of modes, and then the components are uniformly recovered. The method makes the best use of the garbage to the utmost extent, and minimizes the possible pollution caused by the garbage. However, due to the high cost required, this method is not used in most countries except a few developed countries;
2. crushing and direct discharging method: in the early 40 s of the last century in the united states, a food waste disposer has been successfully developed, and the principle is that food waste contained in an inner container is broken by a blade which runs at a high speed, and then the broken food is flushed to a sewer, so that the trouble of discarding and storing kitchen waste is solved. In addition, japanese has also studied kitchen waste treatment apparatuses for a long time, and some are equipped with an ozone deodorizer for removing various odors generated from the kitchen waste. More than 90% of the united states today use such machines, and some cities even force use. The treatment policy and the treatment mode of the kitchen waste of each state in the United states are slightly different, and a plurality of states establish a self kitchen waste treatment and recovery system aiming at the specific local situation.
3. A landfill method: the landfill treatment of the kitchen waste is an anaerobic digestion treatment method, organic matters in the kitchen waste can be decomposed to generate CH4, and the kitchen waste can be completely treated. The technology is convenient, and the problem of residue treatment is avoided, but the method can better treat the kitchen waste, but aims at eliminating the waste, and cannot realize the recycling of the kitchen waste. With the increasingly widespread knowledge of the availability of kitchen waste, the landfill rate of the kitchen waste is on the trend of decreasing no matter in europe, the united states, japan or china, and even many countries prohibit the kitchen waste from entering a landfill site for treatment.
4. Anaerobic treatment: is the most environment-friendly method and can create benefits at present. The anaerobic treatment can generate a large amount of methane, the methane is a clean renewable energy source and can be used for generating electricity and making fuel, and the system is totally closed without peculiar smell, so the anaerobic treatment is considered to be one of the future development directions of the kitchen waste.
5. And (3) treating the microorganisms: namely, the process of decomposing and utilizing organic matters in the kitchen waste through the metabolic growth activity of microorganisms. The fermentation mode mainly comprises solid fermentation and liquid fermentation. Because the solid state fermentation has the characteristics of low energy consumption, short period, high yield and the like, the solid state fermentation is mostly adopted at present. At present, domestic kitchen waste is mainly treated by landfill and incineration, new landfill sites are more and more difficult to find along with the continuous increase of the yield of the kitchen waste, and the incineration method for treating the kitchen waste has the problems of large investment, limited tail gas emission and the like, and is difficult to widely apply. The nutrient components in the kitchen waste are easy to be digested and utilized by animals, and the food waste is a good feed raw material. The traditional method for treating the kitchen waste is to directly feed livestock and poultry without any treatment. However, the mode is easy to infect the epidemic diseases in the crowd to the livestock and poultry through the kitchen waste, and the mode can cause the cross infection of the epidemic diseases between the people and the livestock by bringing harm to the human health together with the food chain accumulated by toxins and harmful substances in the livestock and poultry. In particular, in recent years, the epidemic diseases such as foot-and-mouth disease, avian influenza, mad cow disease and the like raise the attention of people on the safety of feed. However, except the crushing direct discharging method, such as physical sorting treatment, landfill treatment, anaerobic treatment and microbial treatment, the kitchen waste is classified, packaged, put, transported and sorted. Firstly, the classified packaging of kitchen waste usually adopts plastic packaging bags, and the breakage and leakage of the packaging bags are very annoying. Secondly, plastic packaging bag and kitchen garbage extrude each other in input, transportation process, and the bonding is in the same place, causes subsequent sorting very difficult, and not only work load is very big, and tired dirty again moreover. If the fertilizer is not sorted, white pollution (plastic packaging bags) can be caused, and the fertilizer can be used as a fertilizer to pollute the land. If the feed additive is used as a raw material for producing feed, the feed additive cannot be used because of the mixing of a plastic packaging bag. Third, plastic packaging bags consume large amounts of material, resulting in a large amount of waste of resources and white pollution (plastic packaging bags). In addition, eighty percent of the kitchen waste is water, and the kitchen waste is directly packaged by plastic packaging bags, so that the transportation amount is huge.
Therefore, a method for treating and comprehensively utilizing the kitchen waste is urgently needed.
