Problems solved by technology

However, since the raw materials obtained are generally food waste about 12 to 24 hours after production, it has rotted and deteriorated, and it is very easy to pollute equipment and the environment, causing the treatment plant to become a new source of pollution
[0006] Due to the occurrence of leaks, drips and leaks in the collection, transportation and treatment of food waste, secondary pollution is caused, and the food waste treatment industry has become an industry that is disgusted by citizens, which increases the difficulty of food waste and urban domestic waste treatment.

Embodiment 1

[0044] like figure 1 Shown is the flow chart of the kitchen waste treatment method of the present invention, specifically comprising the following steps:

[0045] Step 1, on-site fermentation: Put the freshly produced food waste into the on-site food waste fermentation device installed at the food waste production site, and ferment under the set fermentation conditions according to the different fermentation strains;

[0046] Step 2, transfer: After the food waste is fermented in the on-site fermentation device for the set time, the fermentation liquid is transferred to the fermentation liquid constant temperature transport vehicle, and the fermentation conditions in step 1 are kept unchanged. Continue to ferment in the fermentation container; transport the fermented liquid to the centralized treatment plant through the fermented liquid constant temperature transport vehicle;

[0047] Step 3, concentrated fermentation: After the food waste fermentation liquid is transferred to ...

Embodiment 2

[0062] The food waste treatment process in this embodiment is as follows image 3 As shown, its basic processing flow is the same as the four steps described in embodiment 1, but the processing conditions of each step are slightly different, specifically:

[0063] In step 1, no strains are added, the food waste is not sterilized, and the lactic acid bacteria naturally present in the food waste are used for natural anaerobic fermentation at a fermentation temperature of 37-38°C. The pH value of the fermentation broth was not adjusted during the fermentation process.

[0064] In step 1, the volume of the fermenter in the on-site fermentation treatment device is 150-500 liters, the average volume is 300 liters, and the number is 300.

[0065] In step 2, the food waste constant temperature transport vehicle has a carrying capacity of 4 tons, and each vehicle can transfer the fermentation liquid produced by 13 food waste generation points every round trip.

[0066] The remaining ...

Embodiment 3

[0074] The food waste treatment process in this embodiment is as follows Figure 4 As shown, its basic processing flow is the same as the four steps described in embodiment 1, but the processing conditions of each step are slightly different, specifically:

[0075] In step 1, in step 1, during the first fermentation, put into the fermenter tank the fermented Bacillus L-lactate-producing Bacillus fermentation seed liquid accounting for 1 / 30 of the volume of the fermenter. Additional fermented seed liquid was added, but the remaining 1 / 30 volume of the remaining fermented liquid was used as the seed liquid after each suction of the fermented liquid. Aerobic fermentation, fermentation temperature 55 ℃. The kitchen waste is not sterilized, and the pH value of the fermentation liquid is not adjusted during the fermentation process.

[0076] In step 1, the volume of the fermentation tanks in the on-site fermentation treatment device is 150-500 liters, the average volume is 300 lit...

Abstract

The invention relates to the technical field of waste recycling, in particular to a food waste treating method. The method comprises the following steps of: I, fermenting on site; II, transferring; III, fermenting in a centralized way; and IV, performing subsequent treatment. A treating process is started just after the production of food waste, and an enclosed fermentation state is always kept in the collecting, transferring and centralized treatment process of food waste, so that the breeding of putrefactive bacteria is restrained, secondary pollution is prevented, collected food waste is completed treated on the basis of reclamation, the problems of collection, transportation and treatment of food waste in a certain region in cities are favorably solved in a regional and systematic mode, dry and wet classified recycling of life waste is facilitated, and convenience is brought to management and monitoring.

Description

technical field [0001] The invention relates to the technical field of garbage recycling, in particular to a method for treating kitchen garbage. Background technique [0002] Kitchen waste mainly refers to the organic waste generated in the catering industry, canteens and family cooking and dining, and generally includes leftovers, kitchen raw material scraps, melon peel and fruit scraps, etc. The main components include starch, protein, oil, dietary fiber and other organic components, which have the characteristics of high water content, high oil and salt content, and are easy to rot and smell. [0003] With the improvement and improvement of people's living standards, the amount of kitchen waste is increasing. [0004] At present, the collection, transshipment and treatment of kitchen waste produced by most households in cities in my country adopts the method of mixed collection, mixed transshipment and mixed treatment with urban domestic waste. On the one hand, a varie...
