Description
Technical Field
The utility model belongs to the technical field of refuse treatment, concretely relates to kitchen garbage fermenting installation.
Background
The domestic garbage mainly comprises waste plastics, waste paper, cullet, metal products, fruit peel and vegetable leaves. Kitchen garbage, leftovers and the like. Kitchen waste refers to waste generated after meal cooking. The cooked kitchen garbage comprises leftovers, leftovers and vegetable leaves; the kitchen garbage comprises pericarp, eggshell, tea residue, bone, and scallop. Kitchen waste is one kind of organic waste and is divided into cooked kitchen waste and raw kitchen waste. The cooked kitchen garbage comprises leftovers, leftovers and vegetable leaves; the raw kitchen garbage comprises pericarp, eggshell, tea residue, bone and scallop, and generally refers to raw materials, finished products or residues required by family life diet. But the broad sense of kitchen waste also includes used chopsticks, food packaging materials and the like. Kitchen waste, commonly known as swill, also known as swill and hogwash, is a domestic waste formed in the process of domestic consumption by residents, is extremely easy to rot and deteriorate, emits foul smell, and spreads bacteria and viruses. The main components of the kitchen waste comprise rice and flour food residues, vegetables, animal and vegetable oil, meat and bones and the like, and the kitchen waste comprises starch, cellulose, protein, lipid and inorganic salt in terms of chemical composition. Polluting the environment and influencing the appearance of the market. The kitchen waste contains high organic matters and moisture and is easy to decay and deteriorate under the action of microorganisms; and the longer the waste is placed, the more serious the putrefaction phenomenon becomes. Particularly, in summer, the temperature is higher, the rot and deterioration are quicker, and a large amount of percolating water and malodorous gas are easy to generate at this time, so that mosquitoes are bred, and the bad influence is caused on the environmental sanitation. Is harmful to human health. Meat protein and animal fat substances in the kitchen waste are mainly from livestock and poultry which provide meat food, and after the livestock directly eat the kitchen waste which is not effectively treated, homologous pollution of cannibalism easily occurs, cross infection of epidemic diseases between people and livestock is caused, human health is harmed, and the spread of certain fatal diseases can be promoted. Spread the disease. The open-air storage of kitchen waste can bring about the mass propagation of mosquitoes, flies, mice and insects, which are main vectors of disease circulation. The lower seepage liquid generated during stacking in the kitchen waste enters a sewage treatment system, so that the content of organic matters is increased, the burden of a sewage treatment plant is increased, and the operation cost is increased. The kitchen waste is mainly characterized by rich organic matter content, high water content and easy decay, the properties and smell of the kitchen waste can cause bad influence on environmental sanitation due to kitchen waste treatment, and harmful substances such as pathogenic microorganisms and mycotoxin are easy to grow. The food is delicious before one minute, and becomes garbage after one minute. Due to dietary culture and dinner gathering habits, kitchen waste becomes a common phenomenon. The table is extremely wasteful, and generates a huge amount of kitchen waste every day. Experts consider that the kitchen waste rich in nutrition is a precious renewable resource. However, as the method has not been regarded as important yet and the disposal method is inappropriate, it has become a potential hazard source affecting food safety and ecological safety. Although improper disposal can have serious consequences, kitchen waste is not always available. The national committee for improvement, the jurissin, the chief deputy, indicates that the kitchen waste has the characteristics of wastes and resources, and is a typical 'resource which is misplaced'.
The kitchen waste is solid waste such as leftovers, vegetable leaves, fruit peels, bones, tea leaves and the like generated in the food processing process of the residential life, the catering industry and the food processing industry, the fermentation of the kitchen waste can be divided into anaerobic fermentation and aerobic fermentation, and the anaerobic fermentation degrades macromolecular organic matters such as starch, grease, saccharides and cellulose in the kitchen waste into micromolecular organic matters by utilizing anaerobic flora under the anaerobic condition; aerobic fermentation under aerobic condition, aerobic bacteria are utilized to further decompose and harmlessly treat small molecular organic matters generated by anaerobic fermentation to obtain clinker which can be used as organic fertilizer. The kitchen waste has the characteristics of large production amount, high organic matter content and easy decay, the existing common treatment method is burying, and if the landfill treatment of the landfill site is completely removed, the landfill pressure of the landfill site is increased. Not only pollutes the environment, but also has higher treatment cost, is not beneficial to fully utilizing resources and causes great waste of resources.
