Description
Technical Field
The utility model relates to a technical field of refuse treatment, in particular to kitchen garbage disposal system.
Background
Kitchen waste is a general name of residual food discarded by food units such as families, hotels, restaurants, organs, enterprises and the like, is solid waste generated in the process of life consumption of people, and about 50 percent of most of urban waste in all countries in the world is kitchen waste at present. According to estimation, the kitchen waste production in China is 4500 ten thousand tons in 2000 years, 3800 tons per day in Guangzhou city is achieved, meanwhile, the kitchen waste production in China is increased by about 10% every year, the kitchen waste production newly increased every year reaches 500 ten thousand tons, and the main treatment mode is mainly landfill at present. The kitchen garbage contained in the garbage is not properly treated and utilized due to high water content and low calorific value, so that the garbage occupies a large amount of storage capacity of a landfill, is a main source for generating landfill gas and percolate, causes secondary pollution of the landfill and prevents cost from being greatly increased.
In recent years, the recycling rate of garbage increases, and particularly, the amount of kitchen garbage generated and the proportion of the garbage in urban garbage decrease after the garbage is classified and collected.
The kitchen waste can be treated by various methods, such as: the kitchen waste directly enters a household waste treatment system or a municipal sewer pipe network.
At present, some countries arrange a kitchen waste disposer in a kitchen, directly arrange the kitchen waste disposer between a water outlet at the lower part of a water pool and a sewer drain pipe, and discharge the kitchen waste into a municipal sewer network after being crushed. The method is easy to generate more sewage and odor, directly pollutes the environment, increases the breeding of germs, mosquitoes and flies and the spread of diseases, directly increases the pressure of refuse landfills and urban sewage treatment plants, increases the investment of corresponding systems and various treatment costs, avoids the generation of secondary pollution, and brings great difficulty to subsequent treatment due to high grease content in the waste water of the food and beverage wastes. Some regions require that restaurant waste water is discharged through an oil separation plate or an oil separation tank, otherwise, oil stains in kitchen garbage can be condensed into blocks in a drainage pipeline, and the blocks can be blocked after long-term storage, so that the drainage capacity of cities is greatly reduced, and if the restaurant waste water is in a flood season, the oil stain water can overflow.
The landfill is a common treatment method at present due to simple operation. The kitchen waste is very suitable for landfill gas utilization technology, the gas production speed of the kitchen waste is very high, the stabilization time is short, the recovery and the use of a landfill are facilitated, the proportion of biodegradable components in organic matters of the kitchen waste is high, but the seepage speed liquid is increased due to the overhigh water content of the kitchen waste, the land area meeting the landfill conditions is reduced, the treatment cost is increased, and the kitchen waste subjected to anaerobic decomposition is a main source of biogas and seepage blurred liquid in the landfill, so that the secondary pollution is caused. The treatment method can lose almost all the nutritional value in the kitchen waste, and finally most of carbon in the kitchen waste is converted into methane. In a well-designed landfill about 66% of the biogas can be reused as fuel, but the remaining 34% will go into the atmosphere, with the effect of biogas being about 25 times that of carbon dioxide.
High-temperature aerobic composting is one of the effective methods for treating kitchen waste. Composting is the process of biostabilizing organic solid waste under artificially controlled conditions. The kitchen waste is high in organic matter content and comprehensive in nutrient elements, is a good nutrient anaerobic substance for microorganisms, is very suitable for being used as a composting raw material, is low in content of inert wastes (such as waste plastics) in the kitchen waste, is beneficial to agriculture of composting products, and can be used for forestry, landscapes and the like besides agriculture. The method has the advantages that the treatment method is simple, more nitrogen can be reserved in the finished product, the method has the defects that the field is large, the treatment period is long, some germs are not easy to kill, the sewage and the waste gas generated in the composting field can cause new pollution, the environmental load is increased, if the generated sewage and the waste gas are treated again, extra treatment cost is increased, the high oil content and the high salt content in the kitchen waste are very unfavorable for the growth of microorganisms, and the effect of the high-temperature aerobic composting treatment process is also restricted.
A great deal of research and experiments prove that the kitchen waste is a potential feed raw material. The kitchen waste is used as a raw material, so that the price is low, the supply amount is large, the product is rich in nutrition, the profit margin is large, and the market competitiveness is strong. The relatively mature method for processing the feed by the kitchen waste comprehensively utilizes the granulation technology, the extrusion puffing technology, the drying technology and other means, and the concentration of bacteria in the extruded feed is far lower than that of bacteria in other samples. At present, a plurality of manufacturers develop technical equipment and put the technical equipment into operation, such as an OKADORO boiling type feed drying system of Japan K.K. The main problem of using kitchen waste as feed is the safety of feed, and in the face of raising the disinfection requirement, it must make corresponding regulation on the corresponding equipment and technology, so that it increases the treatment cost, therefore it is necessary to make great care in the selection of said technology.
However, the existing kitchen waste is laborious to treat, high in cost and poor in effect, so how to ensure scientific and reasonable treatment of the kitchen waste becomes a technical problem to be solved by technical personnel in the field.
