Background

The treatment technology of the current kitchen waste mainly comprises the following steps: sanitary landfill treatment, incineration treatment, feed treatment, anaerobic fermentation treatment, aerobic composting treatment, aerobic microorganism treatment and the like.

The aerobic microorganism treatment technology is a more common and mature treatment technology. But not only feed treatment or aerobic composting treatment. In the prior art, except for the high-temperature environment, the whole process needs dehydration, dehumidification or drying to achieve the maximum decrement of the water content.

The process of current kitchen garbage processing mainly adopts:

1. a high-temperature heating mode: the high temperature environment is realized by heating. The existing heating methods mainly include: electric heating, liquefied gas (or natural gas) heating, electromagnetic heating, and the like;

2. the decrement technology comprises the following steps: in the prior art, the reduction dehydration is mostly carried out by draining water or heating to thermal gasification to exhaust. Generally, the water content of the kitchen waste is reduced to a water content close to that of the fermentation of the strains (for example, the water content of a B-type microbial agent in a microecological microbial agent of Shanghai dry-bound Biotech limited company is 50% -60% by fermentation) through pretreatment, such as crushing and extrusion treatment. And then feeding the kitchen waste into a fermentation bin of the kitchen treatment equipment for fermentation, heating the kitchen waste to the fermentation temperature required by the strain through the fermentation bin, and fermenting the kitchen waste under the conditions of certain water content and temperature. And after the water generated in the fermentation process is discharged in a drainage mode, pumping the water to oil-water separation equipment for water treatment. Or by thermal gasification by heating. The air in the fermentation chamber is heated, after the relative humidity of the air reaches the concentration in the high-temperature environment, the ventilation valve is opened, the air in the high-humidity fermentation chamber is discharged out of the chamber, and then the gas is discharged and treated through the deodorization system.

1. by adopting the electric heating type heating and electromagnetic heating technology, the energy efficiency ratio is too low, the highest common energy efficiency ratio can only reach 95%, and the cost is too high. The technology of heating by adopting liquefied gas (or natural gas) is not environment-friendly enough, the energy efficiency ratio is low, and the heating cost is close to the cost of heating technologies such as electric heating type heating, electromagnetic heating and the like.

2. The drainage mode of the decrement technology is treated by water such as oil-water separation, the decrement of the drainage is limited, the effect of real decrement is achieved, and the second mode is matched under most conditions, so that the technical defect is that: secondary pollution is generated, the treatment period is prolonged, the related equipment is various, the treatment process is complex, the equipment cost is high, the post-operation cost is high and the like; the technology of heating to thermal gasification exhaust, thermal gasification process except that need consume a large amount of electric energy, the gas that discharges still need to be handled through deodorization equipment, just can reach emission standard etc. like the combination of deodorization technologies such as UV ultraviolet deodorization, plasma deodorization, spray column, water filtration, and the technical defect is: equipment, treatment cost, field and energy consumption are increased; moreover, the gas after the deodorization treatment affects the surrounding environment, and is liable to cause complaints from surrounding residents.
