Vegetable garbage disposal and resource utilization production process and device thereof

Abstract

The invention relates to a vegetable garbage disposal and resource utilization production process, which comprises the following steps: crushing: crushing vegetables to obtain pasty or pasty vegetable puree; sorting: sorting the obtained vegetable puree to obtain impurities and the vegetable puree subjected to impurity removal; dehydrating: dehydrating the vegetable puree subjected to impurity removal to obtain dehydrated vegetable puree and tail water; air floatation treatment: carrying out air floatation treatment on the obtained tail water to obtain clear water and scum; and fermentation: carrying out aerobic fermentation on the dehydrated vegetable mud to obtain the vegetable organic fertilizer. The invention further provides a corresponding production device, which is used for treating organic garbage sorted out manually or mechanically in cities and villages,wherein the sorted organic garbage reaches the fineness and dryness required by fermentation after being smashed and dehydrated, and is fermented into odorless and sterile organic fertilizer through high-temperature and high-oxygen fermentation, so that transportation resources are saved, breeding of mosquitoes, flies and bacteria is prevented, the environment is protected, and the land is recultivated.

Description

technical field [0001] The invention relates to the field of garbage treatment, in particular to a production process and a production device for making organic fertilizer from vegetable garbage. Background technique [0002] A large part of domestic waste is organic waste such as discarded vegetables, fruits, plants, flowers, etc. Recycling disposal of it can not only return it to the field, but also produce certain economic benefits. It is a trend to use it as a resource. It is imperative. [0003] In the current field of organic waste treatment, organic waste such as discarded vegetables, fruits, plants, and flowers is generally disposed of together with other wastes, and then incinerated for power generation or landfilled after treatment processes such as crushing and compression. However, organic waste such as discarded vegetables, fruits, plants, and flowers has different characteristics from other wastes. First, it has more water, and second, it can extract its nutri...

AI Technical Summary

Problems solved by technology

However, organic waste such as discarded vegetables, fruits, plants, and flowers has different characteristics from other wastes. First, it has more water, and second, it can extract its nutrients and use them as organic fertilizers through resource disposal processes. Organic waste can be used for power generation or If it is directly landfilled, it will cause a waste of resources

[0004] Since discarded vegetables, fruits, plants, flowers and other organic waste are often mixed with various debris such as steel bars, iron blocks, stones, steel ropes, and nylon ropes, it is difficult to directly apply the conventional organic fertilizer production process to vegetable organic fertilizers. production
