Device and method for recycling agricultural organic solid wastes

Abstract

The invention discloses a method for recycling agricultural organic solid wastes, which comprises the following steps of: 1) performing physical pretreatment on different types of agricultural wastes in different modes to form pretreated materials to ensure that different types of agricultural wastes are easily fermented; 2) feeding the pretreated materials into a fermentation tank, and mixing a microbial DM activating agent and the pretreated materials in the process of feeding the pretreated materials into the fermentation tank; 3) turning the pretreated materials which are fed into the fermentation tank, constructing a proper environment for work and reproduction of microbes, supplying oxygen to fermented materials simultaneously and realizing the radiating function; and 4) dischargingthe materials subjected to the fermentation treatment in the fermentation tank.

Description

technical field [0001] The present invention relates to the field of agricultural environment management and resource utilization of agricultural waste, especially to the treatment and utilization of farmland straw, weeds, various vegetables, leaves, stems, fallen fruits and residual plants of economic crops, including garden waste processing and utilization. Background technique [0002] Agricultural production will produce a large amount of waste, such as straw, weeds, vegetable leaves, orchard litter, fallen fruit, etc. In addition, the clean vegetables into the city also leave a large amount of farmland waste in the planting base, and fruit and vegetable planting areas are everywhere It can be seen that all kinds of waste vegetables, rotten leaves and rotten fruits are piled up with flies and insects. Waste vegetables and rotten fruits contain a lot of water, are perishable and smelly, and will pollute the air, rivers and groundwater; in summer, a large number of vegetab...

Problems solved by technology

[0002] Agricultural production will produce a large amount of waste, such as straw, weeds, vegetable leaves, orchard litter, fallen fruit, etc. In addition, the clean vegetables into the city also leave a large amount of farmland waste in the planting base, and fruit and vegetable planting areas are everywhere It can be seen that all kinds of waste vegetables, rotten leaves and rotten fruits are piled up with flies and insects. Waste vegetables and rotten fruits contain a lot of water, are perishable and smelly, and will pollute the air, rivers and groundwater; in summer, a large number of vegetable residues are The breeding grounds of mosquitoes and flies lead to the spread of diseases, causing the majority of villagers to suffer from mosquitoes and flies. In winter, they become places where pests and insects breed and overwinter. Popularity creates conditions; arbitrary stacking of vegetable seedlings and leaves will also block irrigation channels

These waste vegetables and rotten leaves cannot be left in the field as fertilizer because they contain germs; at the same time, some vegetables and leaves have serious drug residues, and livestock will get sick or even die if they eat them. Farmers are unwilling to use them as feed for pigs and other livestock; Straw burning will produce smoke, dust and harmful gas, which not only causes environmental pollution but also wastes resources. Moreover, straw burning has been banned by the state, which leads to a large amount of crop straw that cannot be processed.

If tens of thousands of tons of farmland wastes are not treated and left to rot naturally, it will obviously become a major public hazard, affecting both the quality of life and health of farmers and the environment for agricultural production
