[0018] Examples:

[0019] The flowchart of the present invention is as figure 1 As shown, the method for rapidly processing urban kitchen waste of the present invention includes the following steps:

[0020] 1) First collect, recycle and sort food waste on a large scale in the city;

[0021] 2) After the food waste is collected uniformly, the food waste is broken into fine slurry;

[0022] 3) The fine slurry is extracted with a thick slurry pump, and the high-temperature steam sterilization and drying is carried out quickly, and the non-toxic dry food waste powder produced is quickly bagged and packaged;

[0023] 4) Transport the non-toxic food waste dry powder that can be stored in packaging bags to the countryside. The dry food waste powder and agricultural waste such as bagasse, banana stems, peanut shells and other agricultural wastes will be jointly fermented by biological synergy;

[0024] 5) After fully fermented, the materials can be used as high-quality farmyard fertilizer or a...

Abstract

The invention provides a method for rapidly processing municipal food wastes. The method comprises the following steps: 1, collecting food wastes in a city in a large scale manner, recovering them, and sorting them; 2, crushing the unifiedly recovered food wastes into a fine slurry; 3, extracting the fine slurry with an underflow pump, rapidly carrying out high temperature steam disinfection drying, and rapidly bagging generated nontoxic dry food waste powder; 4, conveying the nontoxic dry food waste powder which is bagged and can be preserved to rural areas, and carrying out biological synergistic fermentation manure rotting on the dry food waste powder together with agricultural wastes of bagasse, banana sticks, peanut shells and the like; and 5, using the fully fermented material obtained in step 4 as a high quality farm manure or a fertilizer for culturing economic animals. The method which has the advantages of simple processing procedure and low cost is a convenient and practical method for processing the municipal food wastes.

Description

technical field [0001] The invention is a method for quickly processing urban kitchen waste, in particular a method for quickly realizing the reduction, harmlessness and recycling of urban kitchen waste by using a two-step method, which belongs to the method for rapidly processing urban kitchen waste transformation technology. Background technique [0002] Kitchen waste is a difficult problem facing the people of our country, and it is also a problem that restricts urban development. It is imminent to solve the problem of chaotic disposal of kitchen waste. However, if the kitchen waste is not treated in a standardized manner, the source of waste food chains such as "sloppy pigs" and "gutter oil" that endanger the health of the people will not be cut off. In order to prevent food waste from becoming a source of wealth for lawbreakers, and also for the health and safety of the general public and the environment, the treatment of food waste must be specialized. Specialization...
